Description

Technical Field

[0001] This application relates to the field of hardware processing technology, and in particular to a fully automatic processing equipment for hardware handles. Background Technology

[0002] Hardware handles are commonly used auxiliary opening components for cabinet doors. Hardware handles come in a variety of shapes to meet all user's personalized needs.

[0003] like Figure 1 The diagram shows a typical existing handle 100. The handle 100 includes a cylindrical handle body 110 and connecting posts 120 radially fixed to both ends of the handle body 110; each connecting post 120 has a threaded hole 130. Therefore, during installation, the handle 100 can be fixed to the door by screws engaging with the threaded holes 130. Depending on the usage environment, there are various models of this handle 100; the length and diameter of different models of handle 100 may vary.

[0004] The machining of the handle 100 mainly involves machining threaded holes 130 into the blank, which includes the handle body 110 and the connecting post 120. The general machining steps are as follows: first, mill the end face of the connecting post 120, then drill a hole along the axial direction on the milled end face of the connecting post 120, and finally tap the drilled hole.

[0005] However, the existing technology has the following problems when machining the threaded hole 130:

[0006] (1) Most of the above processing steps are carried out by workers manually holding the blanks, which makes the processing process more dangerous and the processing precision is also more rough.

[0007] (2) The above processing steps are basically carried out separately, which leads to a long interval between processes, resulting in reduced processing efficiency and a decline in processing quality.

[0008] (3) Even if some processes use mechanical processing, they are generally not suitable for processing different models of handles. As a result, different models of handles need to be matched with different models of processing equipment, which leads to an increase in the overall processing cost of handles.

Detailed Implementation

[0043] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0044] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0045] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0046] One preferred embodiment of this application, such as Figure 2 and Figure 3 As shown, a fully automatic processing equipment for hardware handles includes a worktable 200, a feeding table 300, a loading mechanism 6, a processing mechanism group, and a unloading mechanism 9. The worktable 200 is fixedly mounted to support the feeding table 300. The worktable 200 has a loading station 201, a processing station 203, and an unloading station 202 arranged sequentially along its circumference. The feeding table 300 is rotatably mounted on the worktable 200. Multiple clamping assemblies 5 are mounted on the feeding table 300 along its circumference. The clamping assemblies 5 are used to clamp the blank 101 of the handle 100 being processed. The loading mechanism 6 is located on one side of the loading station 201. The loading mechanism 6 can flip the flat-laid blank 101 so that the processing surface faces upwards and push it into the clamping assembly 5 located at the loading station 201. The clamping assembly 5 can then clamp the blank 101 with the processing surface facing upwards at the processing station 203, thus ensuring the smooth progress of the processing steps. The machining mechanism group is located on one side of the machining station 203. The machining mechanism group is used to perform milling, drilling and tapping operations on the blank 101 clamped by the fixture assembly 5 in sequence. The unloading mechanism 9 is located on one side of the unloading station 202 to push the machined handle 100 out of the fixture assembly 5 for unloading.

[0047] In brief, the processing procedure of the handle 100 is as follows: the feeding table 300 can drive the clamp assembly 5 to rotate around the workbench 200 in the circumferential direction, and then the clamp assembly 5 can pass through the feeding station 201, the processing station 203 and the discharging station 202 in sequence. When the clamp assembly 5 is located at the feeding station 201, the feeding mechanism 6 can push the blank 101 to be processed into the clamp assembly 5 with the processing surface facing upward to realize the feeding of the blank 101. When the clamp assembly 5 is located at the processing station 202, the processing mechanism group can perform corresponding processing procedures on the blank 101. When the clamp assembly 5 is located at the discharging station 203, the discharging mechanism 9 can push the handle 100 processed from the blank 101 out of the clamp assembly 5 to realize discharging. The whole process does not need manual operation, and fully realizes the automatic processing of the handle 100. Compared with the traditional manual operation or process operation, the production efficiency and production quality of the handle 100 can be effectively improved.

[0048] It should be understood that, no matter the feeding, processing or discharging procedure, each procedure needs a certain time, and then the rotation of the feeding table 300 is intermittent rotation, and the specific intermittent time is set according to the longest time required in the above procedures. At the same time, the specific number of the clamp assembly 5 can be set according to actual needs. Generally, the whole processing procedure includes five steps of feeding, milling a plane, drilling a hole, tapping a screw and discharging, and then the number of the clamp assembly 5 is at least five. For the convenience of understanding, the number of the clamp assembly 5 will be taken as five in the following content.

[0049] It should also be understood that the processing surface of the blank 101 is the end surface of the connecting column 120 on the blank 101, and the required threaded hole 130 is obtained by processing the end surface. Therefore, when the blank 101 is processed, it is necessary to ensure that the blank 101 is clamped on the clamp assembly 5 with the processing surface facing upward.

[0050] In the embodiment, as shown in Figure 4 and Figure 5 , the lower end surface of the feeding table 300 is fixedly installed with a gear ring 310, and the lower part of the workbench 200 is fixedly installed with a first driving device 400. The first driving device 400 can be engaged with the gear ring 310 through the gear installed on the output end, and then the rotation of the gear is driven by the first driving device 400 to drive the feeding table 300 to rotate around the workbench 200.

[0051] It should be understood that the specific structure and working principle of the first driving device 400 are known to those skilled in the art, and the common first driving device 400 is a motor.

[0052] One of the embodiments of the application is as shown in Figure 6 , Figure 11 and Figure 12As shown, the clamp assembly 5 comprises a base plate 51, a pair of clamping assemblies 52 and an opening and closing assembly 53. The base plate 51 is fixed to the feeding table 300, and its extending direction coincides with the radial direction of the feeding table 300, and the upper end surface of the base plate 51 can be used to support the handle body 110 of the blank 101. The clamping assemblies 52 are symmetrically arranged at both ends of the base plate 51 along the extending direction, and the clamping assemblies 52 can be opened and closed to clamp and position the connecting column 120 of the blank 101, so that a clamping cavity for clamping the blank 101 can be formed between the clamping assemblies 52 and the base plate 51. The output end of the opening and closing assembly 53 can be connected with the clamping assemblies 52, and the input end of the opening and closing assembly 53 can be connected with the workbench 200. Thus, when the clamp assembly 5 is located at the feeding station 201 and the discharging station 202, the opening and closing assembly 53 can drive the clamping assemblies 52 to open by cooperating with the workbench 200 during the rotation of the feeding table 300, so that the feeding mechanism 6 can push the blank 101 with the processing surface upward into the opened clamping cavity, and the discharging mechanism 9 can push the processed handle 100 out of the opened clamping cavity. When the clamp assembly 5 is located at the machining station 203, the opening and closing assembly 53 can be disconnected from the workbench 200, and then the clamping assemblies 52 can be closed to clamp the blank 101, so as to ensure the clamping stability of the blank 101 during processing.

[0053] It can be understood that when the blank 101 is clamped, only the two connecting columns 120 of the blank 101 are clamped with the end surface upward. That is, by clamping the two connecting columns 120, the entire blank 101 cannot be shaken horizontally, and the vertical direction is the processing direction, and the blank 101 cannot be deviated in the vertical direction by the support of the feeding table 300. Of course, in order to facilitate the structural arrangement of the clamping assembly 52, the area of the feeding table 300 between the clamping assemblies 52 may need to be slotted, and therefore the base plate 51 can be provided to support the handle body 110 of the blank 101.

[0054] Of course, in order to better clamp the blank 101 in the clamping cavity, a placing groove 510 can be arranged on the upper end surface of the base plate 51, which can better support the handle body 110 of the blank 101 placed in the clamp assembly 5. The cross section of the placing groove 510 can be arc-shaped or rectangular, and in the embodiment, the arc-shaped structure is preferred, and in order to facilitate the processing of multiple models of handles 100, the cross-sectional diameter of the placing groove 510 is the maximum diameter of the handle body 110 corresponding to the model of the handle 100 that can be processed.

[0055] In the embodiment, as shown in Figures 5 to 8 and Figure 11 and Figure 12As shown, the feeding table 300 is provided with a groove below the bottom plate 51 corresponding to each clamp assembly 5. The clamping assembly 52 comprises a pair of clamping blocks, a pair of opening and closing plates 523 and a hinge component. The clamping blocks are symmetrically arranged on the end surface of the feeding table 300 on both sides of the extension direction of the bottom plate 51, and the bottom of each clamping block is provided with a pair of third sliding grooves 5202. The opening and closing plates 523 are located in the groove below the bottom plate 51, and the two opening and closing plates 523 are cross arranged between them, and both of them are hinged through the middle part and the hinge component arranged at the bottom of the groove. Both ends of each opening and closing plate 523 correspond to the bottom of the two clamping blocks, and then each opening and closing plate 523 is slidably matched with the third sliding groove 5202 at the bottom of the two clamping blocks through the sliding rod 5231 arranged at both ends. At the same time, one of the clamping blocks can be connected with the opening and closing assembly 53; so when the clamp assembly 5 is located in the feeding station 201 and the discharging station 202, the opening and closing assembly 53 can pull the corresponding clamping block to move along the direction perpendicular to the extension direction of the bottom plate 51, and then the opening and closing plate 523 can drive the two clamping blocks to move away from each other through the sliding of the sliding rod 5231 along the third sliding groove 5202, so as to realize the opening of the clamping cavity. When the clamp assembly 5 is located in the machining station 203, the clamping blocks can move close to each other under the action of the elastic force of the opening and closing assembly 53, so as to realize the closing of the clamping cavity.

[0056] For the convenience of understanding, the opening and closing process of the clamping cavity of the clamping assembly 52 will be described in detail below. The two clamping blocks can be defined as the first clamping block 521 and the second clamping block 522, and the first clamping block 521 can be connected with the opening and closing assembly 53.

[0057] Initially, the clamping cavity is in a closed state, and at this time the sliding rod 5231 at the end of the two opening and closing plates 523 corresponds to the first end of the third sliding groove 5202 at the bottom of the clamping block.

[0058] When the opening of the clamping cavity is needed, such as Figure 7 and Figure 11As shown, the opening and closing assembly 53 can pull the first clamping block 521 to move away from the base plate 51 in a direction perpendicular to the extension direction of the base plate 51. During the movement of the first clamping block 521, the slide rod 5231 can drive the corresponding opening and closing plate 523 to rotate around the hinge component through the extrusion fit between the third sliding groove 5202 and the slide rod 5231, i.e. the slide rod 5231 can slide relative to the third sliding groove 5202 from the first end to the second end close to the middle of the clamping block. Since the two ends of the opening and closing plate 523 move in the same way during the rotation of the opening and closing plate 523 around the hinge component in the middle, the second clamping block 522 can move in the same way as the first clamping block 521 under the drive of the opening and closing plate 523; that is, the first clamping block 521 and the second clamping block 522 move away from the base plate 51 synchronously, and then the first clamping block 521 and the second clamping block 522 can realize the opening of the clamping cavity through the gap formed.

[0059] As shown, Figure 7 and Figure 12 , the opening and closing assembly 53 can drive the first clamping block 521 to move close to the base plate 51 in a direction perpendicular to the extension direction of the base plate 51 through the elastic force, and then the second clamping block 522 can move in the same way as the first clamping block 521 through the action of the opening and closing plate 523, that is, the first clamping block 521 and the second clamping block 522 move close to the base plate 51 synchronously until the connecting column 120 of the blank 101 in the clamping cavity is clamped tightly.

[0060] It should be understood that the gap width formed between the first clamping block 521 and the second clamping block 522 is at least the maximum diameter of the corresponding connecting column 120 in the handle 100 model that can be processed. At the same time, the first end of the third sliding groove 5202 is close to the end of the first clamping block 521, and the second end of the third sliding groove 5202 is close to the middle of the first clamping block 521. Then during the opening process of the clamping assembly 52, the slide rod 5231 can slide from the first end of the third sliding groove 5202 to the second end; during the closing process of the clamping assembly 52, the slide rod 5231 can slide from the second end of the third sliding groove 5202 to the first end.

[0061] Specifically, as shown, Figure 7 , Figure 8 , Figure 11 and Figure 12As shown in the drawings, the first clamping block 521 and the second clamping block 522 are both provided with a positioning groove 5201 on the opposite vertical end faces. Thus, when the blank 101 is clamped, the connecting column 120 of the blank 101 is just located in the area corresponding to the positioning groove 5201, and then when the clamping assembly 52 closes the clamping cavity, the first clamping block 521 and the second clamping block 522 can clamp and position the connecting column 120 through the positioning groove 5201, so as to ensure the stability during the processing of the blank 101.

[0062] It can be understood that the cross-sectional shape of the positioning groove 5201 can be arc-shaped, V-shaped or trapezoidal structure. That is, when the first clamping block 521 and the second clamping block 522 clamp the connecting column 120 of the blank 101 through the positioning groove 5201, the positioning groove 5201 can not only limit the movement trend of the blank 101 perpendicular to the extension direction of the bottom plate 51, but also limit the movement trend of the blank 101 parallel to the extension direction of the bottom plate 51.

[0063] In the embodiment, the specific structure of the opening and closing assembly 53 has various structures, one of which is as shown in Figure 4 、 Figure 6 、 Figure 7 、 Figure 9 、 Figure 11 and Figure 12 As shown in the drawings, the middle part of the workbench 200 is provided with a fixed column 204, and the side part of the fixed column 204 is provided with a cam plate 205 at the corresponding positions of the feeding station 201 and the discharging station 202. At the same time, the opening and closing assembly 53 includes a traction plate 531 and a driving rod 533. The traction plate 531 is in elastic sliding connection with the feeding table 300 perpendicular to the extension direction of the bottom plate 51; the traction plate 531 can be in matched connection with the first clamping block 521. The driving rod 533 is in sliding connection with the feeding table 300, and the first end of the driving rod 533 is provided with a first traction groove 5330 inclined to the radial direction of the workbench 200; the first traction groove 5330 can be in sliding cooperation with the traction rod 5312 provided on the traction plate 531.

[0064] When the clamp assembly 5 is located at the feeding station 201 and the discharging station 202, the driving rod 533 can be moved by the extrusion fitting of the second end and the cam plate 205. In the process of moving the driving rod 533, the first traction groove 5330 and the traction rod 5312 are driven to slide relatively, so as to drive the traction plate 531 to move the first clamping block 521 away from the bottom plate 51 in a direction perpendicular to the extending direction of the bottom plate 51, thereby achieving the opening movement of the clamping assembly 52. When the clamp assembly 5 is located at the machining station 203, the second end of the driving rod 533 can be disengaged from the cam plate 205. At this time, the traction plate 531 can drive the first clamping block 521 to move towards the bottom plate 51 in a direction perpendicular to the bottom plate 51 under the action of the elastic force, thereby achieving the closing movement of the clamping assembly 52.

[0065] Specifically, as shown in Figure 5 、 Figure 9 、 Figure 11 and Figure 12 , the feeding table 300 is provided with a top plate 302 on one side of the clamp assembly 5, and the extending direction of the top plate 302 is parallel to the extending direction of the bottom plate 51. The traction plate 531 is connected to the top plate 302 in sliding connection in a direction perpendicular to the extending direction of the top plate 302 through at least one guide rod 5311 provided on the side away from the first clamping block 521. The guide rod 5311 is further sleeved with a spring 532, and the two ends of the spring 532 are connected to the top plate 302 and the traction plate 531, respectively. Thus, the clamping force of the clamping assembly 52 on the blank 101 is provided by the elastic force of the spring 532, and the elastic force of the spring 532 applied to the clamping assembly 52 through the traction plate 531 is greater than the shaking force generated during the machining of the blank 101.

[0066] It should be understood that, in order to ensure the movement stability of the traction plate 531 and the clamping stability of the clamping assembly 52, the number of guide rods 5311 can be multiple along the extending direction of the top plate 302, for example Figure 9 As shown in the figure, the number of guide rods 5311 is two, and the two guide rods 5311 correspond to the positions of the two clamping assemblies 52, respectively, and each guide rod 5311 is sleeved with a spring 532. In order to ensure that the spring 532 has sufficient elastic force to ensure the clamping stability of the clamping assembly 52 on the blank 101, the spring 532 is preferably a rectangular spring, and the spring 532 is always in a deformed state.

[0067] It should be known that, for the handle 100 made of zinc-aluminum alloy and copper, the cutting force required during processing is small due to the soft material, and thus the shaking force generated is small. Therefore, the elastic force formed by the rectangular spring is sufficient to ensure the clamping stability of the clamping assembly 52 to the blank 101 during the processing of milling a plane, drilling and tapping. At the same time, for the processing of the handle 100 of a larger size, the deformation degree of the spring 532 of the clamping assembly 52 is greater when clamping the corresponding blank 101, and thus the clamping force formed is greater.

[0068] As shown in one of the embodiments of the present application, Figure 6 The fixture assembly 5 further comprises a spacing adjustment assembly 54, which can be connected with the two clamping assemblies 52. When different models of handles 100 need to be processed, according to the model of the handle 100 to be processed, the spacing size between the two connecting columns 120 of the handle 100 can be obtained; and then the spacing adjustment assembly 54 can adjust the spacing between the two clamping assemblies 52 on the fixture assembly 5 to adapt to the change of the clamping size.

[0069] In the present embodiment, the specific structure of the spacing adjustment assembly 54 has various structures, one of which is shown in Figure 4 、 Figure 6 、 Figures 10 to 12 As shown, the middle part of the workbench 200 is provided with a bevel gear 206; each clamping assembly 52 is provided with a second sliding groove 5220, and the extension direction of the second sliding groove 5220 is perpendicular to the extension direction of the bottom plate 51. The spacing adjustment assembly 54 comprises a lead screw shaft 541 and a pair of sliding sleeves 542. The lead screw shaft 541 is rotatably installed on the feeding table 300, and the extension direction of the lead screw shaft 541 is parallel to the extension direction of the bottom plate 51; the lead screw shaft 541 is provided with two reciprocating lead screw sections 5410. The two sliding sleeves 542 are respectively installed on the second sliding grooves 5220 of the two clamping assemblies 52, and the two sliding sleeves 542 are respectively connected with the two reciprocating lead screw sections 5410 of the lead screw shaft 541. The end of the lead screw shaft 541 is installed with a bevel gear 545 through a one-way transmission structure, which is engaged with the bevel gear 206.

[0070] When the processing of the handle 100 is performed, the feeding table 300 can be driven by the first driving device 400 to rotate in the forward direction, at which time the bevel gear 545 rotates in the forward direction through the meshing with the bevel gear ring 206, but the screw shaft 541 can remain stationary through the one-way transmission structure, and the distance between the two clamping assemblies 52 remains constant. When it is necessary to adjust the distance between the two clamping assemblies 52, the feeding table 300 can be driven by the first driving device 400 to rotate in the reverse direction, at which time the bevel gear 545 rotates in the reverse direction through the meshing with the bevel gear ring 206, and the screw shaft 541 can rotate synchronously with the bevel gear 545 through the one-way transmission structure. In the process of rotating the screw shaft 541, the two sliding sleeves 542 can drive the two clamping assemblies 52 to move towards or away from each other through the cooperation with the reciprocating screw rod section 5410 until the distance between the two clamping assemblies 52 meets the processing requirements of the handle 100 of the new model.

[0071] It should be understood that, in order to ensure that the sliding sleeve 542 moves axially under the cooperation of the reciprocating screw rod section 5410 on the screw shaft 541, it is necessary to limit the circumferential rotation of the sliding sleeve 542. Therefore, at least the upper and lower sides of the sliding sleeve 542 can be provided with mutually parallel planes that slide with the upper and lower inner walls of the second sliding groove 5220. For example Figure 10 As shown, the cross section of the sliding sleeve 542 is a rectangular structure. At the same time, since the position of the screw shaft 541 is fixed, in order to ensure that the sliding sleeve 542 does not interfere with the opening and closing of the clamping assembly 52 during cooperation with the clamping assembly 52, the sliding sleeve 542 is installed in the second sliding groove 5220, so that when the clamping assembly 52 is opened and closed, the sliding sleeve 542 will slide relative to the second sliding groove 5220 perpendicular to the extension direction of the bottom plate 51.

[0072] It should also be understood that the second sliding groove 5220 can be arranged on the first clamping block 521 or on the second clamping block 522. However, considering that the opening and closing assembly 53 is connected in cooperation with the first clamping block 521, in order to avoid interference between the opening and closing assembly 53 and the distance adjusting assembly 54, the second sliding groove 5220 can be arranged on the side of the second clamping block 522 away from the first clamping block 521, and the opening and closing assembly 53 and the distance adjusting assembly 54 can be located on the two sides of the clamping assembly 52 respectively, so that the structure can be conveniently arranged.

[0073] In this embodiment, as Figure 5 , Figure 7 and Figure 9As shown, the feeding table 300 is provided with a first sliding groove 301 coinciding with the radial direction of the workbench 200 at the bottom of the groove of the bottom plate 51. The hinged component includes a first sliding block 524 at the lower end in a rectangular shape, and a rotating rod 5241 at the upper end; the hinged component can be hinged to the middle part of the opening and closing plate 523 through the rotating rod 5241, and the hinged component can also be slidingly matched with the first sliding groove 301 through the first sliding block 524 at the lower end. At the same time, the side of the first clamping block 521 away from the second clamping block 522 is provided with a clamping block 5211, and the traction plate 531 is slidingly connected with the clamping block 5211 parallel to the extension direction of the bottom plate 51 through the clamping groove 5310 provided on one side.

[0074] When the opening and closing of the clamping assembly 52 is performed, the traction plate 531 can pull the first clamping block 521 to move perpendicular to the extension direction of the bottom plate 51 through the clamping of the clamping groove 5310 and the clamping block 5211, and the hinged component is limited in the circumferential direction through the first sliding block 524 and the first sliding groove 301, so that the opening and closing plate 523 can drive the second clamping block 522 to move synchronously with the first clamping block 521 around the rotating rod 5241.

[0075] When the distance adjustment of the clamping assembly 52 is performed, the second clamping block 522 moves under the drive of the screw shaft 541, and the first clamping block 521 can move parallel to the extension direction of the bottom plate 51 along the clamping groove 5310 through the clamping block 5211 by the connection of the first clamping block 521 and the second clamping block 522 by the opening and closing plate 523; at the same time, the opening and closing plate 523 can also drive the hinged component to move parallel to the extension direction of the bottom plate 51 along the first sliding groove 301 through the first sliding block 524. In turn, the actions between the opening and closing assembly 53 and the distance adjustment assembly 54 can not interfere with each other.

[0076] It should be known that when the distance adjustment of the clamping assembly 52 is needed, generally the processing of the new type of handle 100 is needed, at this time there is no blank 101 on the clamp assembly 5, i.e. the first clamping block 521 and the second clamping block 522 are in the closed state with the smallest gap; at this time the sliding rod 5231 at the end of the opening and closing plate 523 corresponding to the first clamping block 521 and the second clamping block 522 is located at the two ends of the corresponding third sliding groove 5202, and when the second clamping block 522 moves parallel to the extension direction of the bottom plate 51 under the drive of the sliding sleeve 542, the first clamping block 521 can immediately move synchronously with the second clamping block 522.

[0077] It can be understood that the center of the bevel gear 206 needs to coincide with the center of rotation of the feeding table 300, but the screw shaft 541 is located on one side of the clamping assembly 52 and does not coincide with the radial direction of the workbench 200. Therefore, the one-way transmission structure needs to perform one-way transmission on the screw shaft 541, and also needs to adapt to the transmission position between the screw shaft 541 and the bevel gear 206.

[0078] Specifically, as shown in Figures 10 to 12 , the one-way transmission structure includes a rotating shaft 544 and a one-way bearing 546. The rotating shaft 544 is rotatably installed on the feeding table 300, and the extension direction of the rotating shaft 544 coincides with the radial direction of the workbench 200. The bevel gear 545 is installed on the first end of the rotating shaft 544 through the one-way bearing 546, and the second end of the rotating shaft 544 is meshed with the first gear 543 installed on the end of the screw shaft 541 through the installed second gear 547. Further, when the first driving device 400 drives the feeding table 300 to rotate in the reverse direction, the rotating shaft 544 can drive the second gear 547 to rotate through the engagement of the one-way bearing 546, so that the screw shaft 541 is driven to rotate through the meshing of the second gear 547 and the first gear 543. Since the rotating direction of the screw shaft 541 is single, but the spacing adjustment of the clamping assembly 52 can be spacing increase or decrease, the reciprocating screw segment 5410 is arranged on the screw shaft 541 to cooperate with the sliding sleeve 542, so that the single rotation of the screw shaft 541 can drive the clamping assembly 52 to increase or decrease the spacing through the reciprocating screw segment 5410.

[0079] One of the embodiments of the present application, as shown in Figure 2 , Figure 3 , Figures 13 to 16 , the feeding mechanism 6 includes a conveying belt 61 and a material lifting assembly 62. The material lifting assembly 62 is provided with a U-shaped material lifting groove 6240 in cross section, and the axial direction of the material lifting groove 6240 coincides with the radial direction of the workbench 200 and is flush with the height of the clamp assembly 5. The conveying belt 61 is arranged on one side of the material lifting assembly 62 for flat conveying of the blank 101. When feeding the blank 101, the material lifting assembly 62 can perform a first action and a second action. The first action: the material lifting assembly 62 directs the opening of the material lifting groove 6240 towards the conveying belt 61, so that the blank 101 is conveyed into the material lifting groove 6240 in a flat state with the machining surface facing away from the material lifting assembly 62. The second action: the material lifting assembly 62 is adapted to drive the material lifting groove 6240 to rotate to the opening upward, and push the blank 101 in the material lifting groove 6240 out to the feeding station 201.

[0080] Understandably, when feeding the blank 101, it is generally in a flat state, that is, the connecting post 120 of the blank 101 is laid flat on the conveyor belt 61. However, when processing the blank 101, it is necessary to ensure that the end face (i.e., the processing surface) of the connecting post 120 of the blank 101 is facing upwards. Therefore, by setting the top material assembly 62, the feeding mechanism 6 can ensure that the blank 101 is fed from the conveyor belt 61 to the clamping assembly 5 located at the feeding station 201, while also raising the blank 101 from a flat state to a position with the processing surface facing upwards.

[0081] It should be understood that the specific structure and working principle of the conveyor belt 61 are well-known to those skilled in the art, and therefore will not be described in detail here. For the blank 101 to be laid flat on the conveyor belt 61 with the connecting column 120 facing away from the top material assembly 62, the blank 101 can be placed on the conveyor belt 61 manually, or it can be placed on the conveyor belt 61 by mechanical means.

[0082] In this embodiment, the top material assembly 62 has various specific structures, one of which is as follows: Figures 13 to 16 As shown, the top-loading assembly 62 includes a second drive device 621, a limiting seat 623, and a rotating seat 624. The limiting seat 623 is fixedly installed; the rotating seat 624 is rotatably mounted to the limiting seat 623 through a rotating groove 6230 provided on the limiting seat 623 via its arc-shaped outer side. The loading trough 6240 is disposed on the rotating seat 624, and a drive groove is provided on the inner side of the loading trough 6240. The drive groove includes a second groove segment 6242 and a third groove segment 6243; wherein, the third groove segment 6243 is parallel to the axial direction of the loading trough 6240, the second groove segment 6242 is inclined to the third groove segment 6243, and the second groove segment 6242 is located near the end of the loading trough 6240 away from the loading station 201. The second drive device 621 is fixedly installed, and the second drive device 621 extends into the loading trough 6240 through a push rod installed at its output end, and the push rod can cooperate with the drive groove through a drive block 6210 provided on its outer side.

[0083] When the first action is performed, the push rod approaches the end of the feeding groove 6240 away from the feeding station 201, so that the drive block 6210 cooperates with the end of the second groove section 6242 away from the third groove section 6243, and at this time the push rod will not interfere with the process of the blank 101 being fed into the feeding groove 6240. When the second action is performed, the push rod moves axially along the loading groove 6240 under the drive of the second drive device 621, thereby pushing the blank 101 located in the loading groove 6240 to the loading station 201 until the blank 101 is removed from the loading groove 6240 and located in the clamping cavity of the fixture assembly 5. During this process, the drive block 6210 can first slide along the second groove segment 6242 to drive the rotary seat 624 to rotate around the rotating groove 6230 of the limiting seat 623 until the opening of the loading groove 6240 is facing upward, thereby allowing the blank 101 to be machined with the surface facing upward. Then, the drive block 6210 slides along the third groove segment 6243 to drive the rotary seat 624 to keep the opening of the loading groove 6240 facing upward, so that the blank 101 is pushed into the clamping cavity with the machined surface facing upward.

[0084] It should be understood that, in order to avoid interference between the push rod and the blank 101 during the first action, the extension length of the feeding trough 6240 can be set to be greater than the width of the conveyor belt 61; that is, as Figure 15 As shown, the rotary table 624 extends a certain length on the side of the conveyor belt 61 away from the loading station 201; thus, the second groove segment 6242 can be set in the loading groove 6240 corresponding to the extended length. Therefore, during the first action, the push rod is located in the loading groove 6240 corresponding to the extended length to avoid interference with the blank 101. Furthermore, during the second action, the push rod can engage with the second groove segment 6242 via the drive block 6210 at the initial stage of movement to drive the rotary table 624 to rotate.

[0085] It should also be noted that the opening width of the feeding trough 6240 is at least the maximum diameter of the handle body 110 in the handle 100 models that can be processed. Furthermore, the rotation angle of the rotary seat 624 is related to the angle between the opening of the feeding trough 6240 and the horizontal direction during the first action; that is, if the angle between the opening of the feeding trough 6240 and the horizontal direction is α, then the rotation angle of the rotary seat 624 is 90°-α. The feeding trough 6240 is flush with or lower than the height of the conveyor belt 61. Therefore, the central angle corresponding to the projected arc length of the second trough segment 6242 along the axial direction of the feeding trough 6240 is 90°-α. Meanwhile, in order to ensure the stability of the feeding trough 6240 during the first action, the drive trough also includes a first trough segment 6241, which is parallel to the axial direction of the feeding trough 6240 and is connected to the end of the second trough segment 6242 away from the third trough segment 6243. When the first action is performed, the push rod is located in the first trough segment 6241 through the drive block 6210.

[0086] In this embodiment, as shown in Figure 15 and Figure 16 , the transposition 624 is provided with an extension plate 6244 on the opening side of the feeding groove 6240, so that when the first action is performed, the feeding groove 6240 and the conveying belt 61 can be connected through the extension plate 6244 to ensure that the blank 101 can be smoothly discharged into the feeding groove 6240.

[0087] Specifically, as shown in Figure 13 , the limiting seat 623 and the second driving device 621 are fixedly installed on the first mounting seat 622, and the first mounting seat 622 can be fixedly arranged. The specific structure and working principle of the second driving device 621 are known to those skilled in the art, and common second driving devices 621 include cylinders, hydraulic cylinders, and linear motors.

[0088] One of the embodiments of the present application, as shown in Figure 2 , Figure 4 , Figure 19 and Figure 20 , the fixed column 204 in the middle of the workbench 200 is provided with a mounting table 207 at the top. The blanking mechanism 9 includes a fifth driving device 91, a guide plate 92, and a push rod 93. The guide plate 92 is fixed above the blanking station 202 through a fourth mounting seat 94; the guide plate 92 is provided with a first guide groove 921 and a second guide groove 922 which are communicated in L shape, the first guide groove 921 is vertically arranged and close to the inner side of the workbench 200, the second guide groove 922 is communicated with the lower end of the first guide groove 921, and the extension direction of the second guide groove 922 is parallel to the radial direction of the workbench 200. The push rod 93 is vertically arranged and slidably connected with the first guide groove 921 and the second guide groove 922 through a rectangular third sliding block 931 at the upper end. The height of the mounting table 207 is higher than that of the guide plate 92, the fifth driving device 91 is installed on the mounting table 207, the output end of the fifth driving device 91 is hingedly connected with the upper part of the push rod 93 through a hinge plate 911, and the driving direction of the fifth driving device 91 coincides with the radial direction of the workbench 200.

[0089] When the feeding table 300 rotates, the push rod 93 is located at the upper end of the first guide slot 921 through the third sliding block 931, so that there is a certain gap between the lower end of the push rod 93 and the feeding table 300, thereby ensuring that the feeding table 300 can rotate smoothly. When the pull handle 100 needs to be discharged, the fifth driving device 91 can drive the hinged plate 911 to move along the radial direction of the workbench 200, and then the push rod 93 can perform the first process and the second process under the drive of the hinged plate 911. The first process: the third sliding block 931 slides downward from the upper end of the first guide slot 921, so that the lower end of the push rod 93 moves downward into the opened clamping cavity of the clamp assembly 5. The second process: the third sliding block 931 slides from the inner end to the outer end of the second guide slot 922, so that the push rod 93 pushes the pull handle 100 in the clamping cavity of the clamp assembly 5 through the lower end to move to the outside of the feeding table 300, until the pull handle 100 falls from the clamp assembly 5 to the collecting device (not shown) below the feeding table 300. When the discharging of the pull handle 100 is completed, the fifth driving device 91 can drive the hinged plate 911 to move reversely, and then the push rod 93 slides along the second guide slot 922 and the first guide slot 921 through the third sliding block 931 to the upper end of the first guide slot 921.

[0090] It can be understood that the specific structure and working principle of the fifth driving device 91 are known to those skilled in the art, and common fifth driving devices 91 include cylinders, hydraulic cylinders, and linear motors.

[0091] As shown in one of the embodiments of the present application, Figure 2 , Figure 3 and Figure 18 , the processing mechanism group includes a plurality of processing mechanisms arranged along the circumferential direction of the feeding table 300, and the plurality of processing mechanisms are respectively used for milling a flat surface, drilling a hole, and tapping a thread on the end surface of the connecting column 120 of the blank 101. The processing mechanism includes a third driving device 702 and a pair of processing units 704; the third driving device 702 is fixedly arranged through a second mounting seat 701, and the two processing units 704 are connected to the output end of the third driving device 702; the connecting line of the two processing units 704 is parallel to the radial direction of the workbench 200. When the blank 101 needs to be processed, the third driving device 702 can drive the processing unit 704 to move downward to approach the blank 101 clamped on the clamp assembly 5, and then the corresponding processing procedure is performed through the processing unit 704.

[0092] It can be understood that, according to different processing procedures, the processing units 704 include milling cutter assemblies, drilling assemblies and tapping assemblies; and the corresponding processing mechanisms respectively include a milling plane mechanism 71 of the milling cutter assembly, a drilling mechanism 72 of the drilling assembly and a tapping mechanism 73 of the tapping assembly. The specific structure and working principle of the milling cutter assembly, the drilling assembly and the tapping assembly are well known to those skilled in the art, and therefore will not be described in detail here. At the same time, the specific structure and working principle of the third driving device 702 are also well known to those skilled in the art, and common third driving devices 702 include air cylinders, hydraulic cylinders and linear motors, etc.

[0093] In this embodiment, as shown in Figure 2 and Figure 13 , the workbench 200 is also provided with an adjusting mechanism 8, and each processing unit 704 on the processing mechanism can cooperate with the adjusting mechanism 8. When different types of handles 100 need to be processed, according to the type of the handle 100 to be processed, the spacing size between the two connecting columns 120 of the handle 100 can be obtained, and then the adjusting mechanism 8 can adjust the spacing between the two processing units 704 on each processing mechanism according to the spacing size of the connecting columns 120.

[0094] In this embodiment, the adjusting mechanism 8 has various specific structures, one of which is as shown in Figure 17 and Figure 18As shown, the adjusting mechanism 8 comprises a fourth driving device 81, a first plate set 82 and a second plate set 83. The first plate set 82 comprises a plurality of first mounting plates 821, and adjacent first mounting plates 821 are connected through a traction structure. The second plate set 83 comprises a plurality of second mounting plates 831 corresponding to the first mounting plates 821, and adjacent second mounting plates 831 are connected through a traction structure. The two machining units 704 on each machining mechanism are respectively mounted on the corresponding first mounting plate 821 and second mounting plate 831. The first mounting plate 821 and the second mounting plate 831 are both slidingly mounted on the support plate 703 provided at the output end of the third driving device 702, and the sliding directions of the first mounting plate 821 and the second mounting plate 831 coincide with the radial direction of the workbench 200. The fourth driving device 81 is fixedly mounted on the mounting table 207, and the fourth driving device 81 is connected with the corresponding first mounting plate 821 and second mounting plate 831 through the output end of the bidirectional screw rod 811. When it is necessary to adjust the distance between the machining units 704 on each machining mechanism, the fourth driving device 81 can drive the bidirectional screw rod 811 to rotate, so that the first mounting plate 821 and the second mounting plate 831 connected with the bidirectional screw rod 811 move towards or away from each other, and the remaining first mounting plates 821 and second mounting plates 831 move synchronously through the traction structure. In turn, the machining units 704 of the same machining mechanism mounted on the first mounting plate 821 and the second mounting plate 831 can move towards or away from each other along the radial direction of the workbench 200 to adjust the distance between the two machining units 704 to adapt to the machining of the new type of handle 100.

[0095] It can be understood that the specific structure and working principle of the fourth driving device 81 are also known to those skilled in the art, and the fourth driving device 81 preferably adopts a motor.

[0096] It should be appreciated that the number of machining mechanisms is at least three, and the number of first mounting plates 821 and second mounting plates 831 included in the first plate group 82 and the second plate group 83 is at least three. If the number of first mounting plates 821 is the same as the number of machining mechanisms, one of the first mounting plates 821 and the corresponding second mounting plate 831 need to be connected to the double lead screw 811 through the connection block 803 while being used to mount the machining unit 704 and being connected to the support plate 703. The connection block 803 may cause interference with the mounting structure. Therefore, preferably, the number of first mounting plates 821 and second mounting plates 831 is greater than the number of machining mechanisms. For example, if the number of machining mechanisms is three, the number of first mounting plates 821 and second mounting plates 831 can be four, of which three first mounting plates 821 and second mounting plates 831 can be mounted corresponding to the machining units 704 on the machining mechanisms, and the remaining first mounting plate 821 and second mounting plate 831 can be connected to the double lead screw 811 through the connection block 803.

[0097] Specifically, as shown in Figure 17 and Figure 18 , the first mounting plates 821 and the second mounting plates 831 corresponding to the machining mechanisms are connected to the slide groove on the support plate 703 through the second slide block 804 arranged at the upper end to slide in the radial direction of the workbench 200. At the same time, the first mounting plates 821 and the second mounting plates 831 can stably mount the corresponding machining units 704 through the third mounting seat 805 fixed at the lower end to ensure the machining stability of the machining units 704.

[0098] In this embodiment, the traction structure has various specific structures. For example, as shown in Figure 17 and Figure 18 , the traction structure includes a second traction groove 801 and a traction block 802 arranged on two adjacent first mounting plates 821, respectively, and the traction block 802 and the second traction groove 801 are connected to slide. When one of the first mounting plates 821 moves under the drive of the double lead screw 811, the remaining first mounting plates 821 can be driven to move synchronously in the parallel direction of the radial direction of the workbench 200 through the relative sliding of the traction block 802 along the second traction groove 801.

[0099] It can be understood that the extension direction of the second traction groove 801 and the traction block 802 is straight, and the extension direction is perpendicular to the radial direction of the workbench 200. In addition, there should be a certain gap between the adjacent first mounting plates 821 and the adjacent second mounting plates 831, so that the adjacent first mounting plates 821 and the adjacent second mounting plates 831 will not interfere with each other during the movement when adjusting the spacing of the machining units 704.

[0100] It should be understood that the processing time of the milling flat, drilling and tapping processes of the blank 101 is not necessarily the same. For example, in one case, the milling flat mechanism 71 drives the corresponding processing unit 704 to perform milling flat processing on the blank 101 through the third driving device 702, and the drilling mechanism 72 drives the corresponding processing unit 704 to complete the processing of the blank 101 and is located at the highest position through the third driving device 702, at this time, the corresponding processing unit 704 of the milling flat mechanism 71 and the corresponding processing unit 704 of the drilling mechanism 72 have a certain height difference in the vertical direction; That is, the two first mounting plates 821 corresponding to the two processing mechanisms and the two second mounting plates 831 corresponding to the two processing mechanisms have a certain height difference. Therefore, in order to ensure the stability of the entire structure of the first plate group 82 and the second plate group 83 under the above condition; The second traction groove 801 can be provided with a certain height in the vertical direction, and when there is a height difference between the adjacent two first mounting plates 821 and the adjacent two second mounting plates 831, the second traction groove 801 and the traction block 802 can still be stably connected.

[0101] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.
