[0042] In order to solve the problems of low processing efficiency and difficult positioning and clamping of existing multi-process processing equipment, an embodiment of the present application provides a multi-station machining equipment. Through the cooperation of a feeding mechanism and a fixing mechanism, multiple workpieces to be processed can be processed sequentially at different processing stations, thereby reducing manual participation and improving production efficiency.

[0043] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily.

[0044] like Figure 1 As shown, the multi-station machining equipment provided in the embodiment of the present application includes a frame 100, a feeding mechanism 200, a plurality of fixing mechanisms 300 and a plurality of processing stations 400, wherein the frame 100 is used to support the feeding mechanism 200, the fixing mechanism 300 and the processing stations 400.

[0045] In some embodiments, Figure 2 As shown, the rack 100 includes six support columns 110, two support beams 120, a first platform 130 and a second platform 140, wherein the six support columns 110 extend along a third direction, and the lower ends of the six support columns 110 are supported on the ground; the two support beams 120 are fixedly connected to the rack 100, and the two support beams 120 extend along a first direction and are arranged opposite to each other along a second direction, and the first direction is, for example, Figures 1 to 6 The x-axis direction shown, the second direction can be, for example Figures 1 to 6 The y-axis direction shown, the third direction can be, for example, Figures 1 to 6 The two support beams 120 are used to support the feeding mechanism 200; the first platform 130 and the second platform 140 are fixedly connected to the upper end of the support column 110, and the first platform 130 and the second platform 140 are arranged on both sides of the frame along the second direction.

[0046] The frame 100 also includes a loading area 150 and an unloading area 160. The loading area 150 is used to place the workpiece 10 to be processed, and the loading method is, for example, manual placement or loading with a mechanical gripper; the finished product stacking area 160 is used to place the finished workpiece after processing at each processing station 400.

[0047] The feeding mechanism 200 is arranged on two supporting beams 120. The feeding mechanism 200 is located between the first platform 130 and the second platform 140 in the second direction. The feeding mechanism 200 is used to transport the workpiece 10 to be processed to each processing station 400 along the first direction, and then the workpiece 10 to be processed is fixed by the fixing mechanism 300.

[0048] A plurality of fixing mechanisms 300 are arranged at intervals along the first direction, and each fixing mechanism 300 includes a pre-positioning device 310 and a clamping device 320. The pre-positioning device 310 is fixedly installed on the first platform 130 and the second platform 140. The pre-positioning device 310 is used to pre-position the workpiece 10 to be processed delivered by the feeding mechanism 200, and the clamping device 320 clamps the workpiece 10 to be processed after the pre-positioning, and then each processing station 400 processes the fixed workpiece 10 to be processed. The number of fixing mechanisms 300 is equal to the number of processing stations 400, and each fixing mechanism 300 corresponds to a processing station 400.

[0049] Each processing station 400 includes one or two processing devices 410. When the processing station 400 includes one processing device 410, the processing device 410 is installed on the first platform 130 or the second platform 140. When the processing station 400 includes two processing devices 410, the two processing devices 410 are installed on the first platform 130 and the second platform 140 along the second direction. Different processing stations 400 have different processing devices 410. For example, each processing station 400 is a chamfering station 420, a first punching station 430, a second punching station 440, a slot milling station 450, a cutting station 460, and a milling plane station 470 in the direction from the loading area 150 to the finished product coding area 160.

[0050] The processing process of the above-mentioned multi-station machining equipment is as follows: the feeding mechanism 200 transports the workpiece 10 to be processed in the loading area 150 to the pre-positioning device 310 corresponding to the chamfering station 420, and then the corresponding clamping device 310 clamps the workpiece 10 to be processed, and then the processing device 410 of the chamfering station 420 chamfers the workpiece 10 to be processed. After the processing is completed, the feeding mechanism 200 transports the workpiece 10 to be processed to the first punching station 430. At the same time, the feeding mechanism 200 transports another workpiece 10 to be processed in the loading area 150 to the chamfering station 420. The first punching station 430 and the chamfering station 420 process the two workpieces 10 to be processed at the same time. According to this step, the workpiece 10 to be processed is processed in each processing station 400 in turn, and is transported to the finished product coding area 160 by the feeding mechanism 200 after the processing is completed.

[0051] In the multi-station machining equipment provided in the embodiment of the present application, a plurality of workpieces 10 to be processed are transported to different processing stations 400 by a feeding mechanism 200, and then the workpieces 10 to be processed are pre-positioned by a pre-positioning device 310 in a fixing mechanism 300, and then clamped by a clamping device 320 in the fixing mechanism 300. The pre-positioning and clamping processes do not require manual operation, thereby reducing manual participation, and a plurality of workpieces 10 to be processed can be processed simultaneously by different processing stations 400, thereby improving production efficiency and meeting the requirements of mass production.

[0052] In some exemplary embodiments, reference Figure 1 and Figure 3 The pre-positioning device 310 includes two first positioning reference blocks 3110 and one second positioning reference block 3120, wherein the two first positioning reference blocks 3110 are arranged relatively to each other along the second direction and are respectively installed on the first platform 130 and the second platform 140; in the second direction, the first positioning reference block 3110 is closer to the feeding mechanism 200 than the processing device 410, that is, the first positioning reference block 3110 is installed on the edge of the first platform 130 and the second platform 140 on the side close to the feeding mechanism 200.

[0053] like Figure 3 As shown, the first positioning reference block 3110 is a block structure with a groove, and the shape of the groove is adapted to the shape of the workpiece 10 to be processed, so that the workpiece 10 to be processed can be just stuck in the first positioning reference block 3110. In this way, the workpiece 10 to be processed will not move in the first direction. In addition, the self-weight of the workpiece 10 to be processed ensures that it will not move in the third direction after falling on the first positioning reference block 3110. Therefore, the first positioning reference block 3110 realizes the pre-positioning of the workpiece 10 to be processed in the first direction and the third direction.

[0054] Continue to refer Figure 1and Figure 3 The second positioning reference block 3120 is installed on the second platform 140. In the second direction, the second positioning reference block 3120 is located on the side of the first positioning reference block 3110 away from the feeding mechanism 200. When the second positioning reference block 3120 pre-positions the workpiece 10 to be processed, the second positioning reference block 3120 is used to abut against one end of the workpiece 10 to be processed, thereby achieving the pre-positioning of the workpiece 10 to be processed in the second direction.

[0055] In this embodiment, the length of the groove of the first positioning reference block 3110 in the first direction is adjustable, and the distance between the second positioning reference block 3120 and the first positioning reference block 3110 in the second direction is also adjustable, so that workpieces 10 of different sizes can be pre-positioned.

[0056] In some embodiments, the pre-positioning device 310 also includes a baffle 3130. In the first direction, the baffle 3130 is installed on the second platform 140 and is located on the upstream side of the second positioning reference block 3120. Along the direction from upstream to downstream, the baffle 3130 is inclined toward the feeding mechanism 200, wherein the upstream side is one side of the loading area 150 in the first direction, and the direction from upstream to downstream is the direction from the loading area 150 to the finished product coding area 160 in the first direction, that is, the conveying direction of the workpiece 10 to be processed.

[0057] The baffle 3130 includes two planes that are perpendicular to each other, one of which is rotatably connected to the second platform 140 so that the inclination angle of the baffle 3130 is adjustable; the other plane is used to adjust the position of the workpiece 10 to be processed in the second direction during the process of conveying the workpiece 10 to be processed from upstream to downstream, so as to avoid interference between the workpiece 10 to be processed and the second positioning reference block 3120 during pre-positioning.

[0058] Through the cooperation of the first positioning reference block 3110 , the second positioning reference block 3120 and the baffle 3130 in the pre-positioning device 310 , the pre-positioning of the workpiece 10 to be processed in the first direction, the second direction and the third direction is achieved.

[0059] In some embodiments, reference Figure 1 and Figure 3 The clamping device 320 includes a group of first clamping devices 3210, and two first clamping devices 3210 in the same group of first clamping devices 3210 are relatively installed on both sides of the feeding mechanism 200 along the second direction; each first clamping device 3210 cooperates with a first positioning reference block 3110 to achieve the fixation of the workpiece 10 to be processed in the first direction and the third direction.

[0060] like Figure 4As shown, the first clamping device 3210 includes a connecting rod clamping cylinder 3211, a first clamping block 3212, a first connecting rod 3213, a second connecting rod 3214, a third connecting rod 3215 and a cylinder support seat 3216; wherein, the cylinder support seat 3216 is fixedly installed on the supporting beam 120, and the cylinder support seat 3216 is used to support the connecting rod clamping cylinder 3211, the output end of the connecting rod clamping cylinder 3211 is fixedly connected to the first connecting rod 3213, the first end of the second connecting rod 3214 is rotatably connected to the second end of the first connecting rod 3213, the second end of the second connecting rod 3214 is rotatably connected to the first end of the first clamping block 3212, the second end of the first clamping block 3212 is rotatably connected to the first positioning reference block 3110, the first end of the third connecting rod 3215 is rotatably connected to the second connecting rod 3214, and the second end of the third connecting rod 3215 is rotatably connected to the first positioning reference block 3110.

[0061] The third end of the first pressing block 3212 is designed to be L-shaped, and gaskets are installed on the two surfaces that contact the workpiece 10 to be processed. The material of the gaskets can be, for example, polyurethane or nylon.

[0062] When it is necessary to clamp the pre-positioned workpiece 10 to be processed, the connecting rod clamping cylinder 3211 is started, and the output end of the connecting rod clamping cylinder 3211 pushes the first connecting rod 3213 and then pushes the second connecting rod 3214 to move. Since the second end of the third connecting rod 3215 and the second end of the first clamping block 3212 are both rotatably connected to the first positioning reference block 3110, the first clamping block 3212 will make a circular motion with the connecting axis between its second end and the first positioning reference block 3110 as the center. In this way, the first positioning reference block 3110 contacts two surfaces of the workpiece 10 to be processed, and the first clamping block 3212 contacts the other two surfaces of the workpiece 10 to be processed, thereby achieving the fixation of the workpiece 10 to be processed in the first direction and the third direction.

[0063] The first clamping device 3210 is pneumatically driven and has a simple structure. It does not require manual clamping and can achieve rapid fixation.

[0064] In some embodiments, Figure 5 As shown, the clamping device 320 further includes a second clamping device 3220 , and the second clamping device 3220 and the second positioning reference block 3120 are arranged on both sides of the feeding mechanism 200 along the second direction opposite to each other.

[0065] The second clamping device 3220 includes a rotating cylinder 3221 and a second clamping block 3222 , wherein the rotating cylinder 3221 is fixedly mounted on the first positioning reference block 3110 , and the output end of the rotating cylinder 3221 is fixedly connected to the second clamping block 3222 .

[0066] When it is necessary to clamp the pre-positioned workpiece 10 to be processed, the rotating cylinder 3221 is started, and the output end of the rotating cylinder 3221 together with the second clamping block 3222 rotates until the second clamping block 3222 is aligned with the workpiece 10 to be processed, and moves along the second direction to clamp the workpiece 10 to be processed. In this way, the second clamping device 3220 cooperates with the second positioning reference block 3120 to fix the workpiece 10 to be processed in the second direction.

[0067] Since the second clamping device 3220 is located between the first positioning reference block 3110 and the processing device 410, and the rotary cylinder 3221 is a cylinder whose output end rotates while moving axially, the rotary cylinder 3221 has a compact structure, a small size, and saves more space.

[0068] In some embodiments, Figure 6 As shown, the feeding mechanism 200 includes a translation mechanism 210 and a lifting mechanism 220 . The translation mechanism 210 is configured to move the workpiece 10 to be processed along a first direction of the frame 100 , and the lifting mechanism 220 is configured to move the workpiece 10 to be processed up and down relative to the frame 100 .

[0069] The translation mechanism 210 includes a first cylinder 2110, a base plate 2120 and two guide rails 2130, wherein the first cylinder 2110 is fixedly mounted on the frame 100, the two guide rails 2130 are respectively fixedly mounted on two supporting beams 120, and the two guide rails 2130 are spaced apart in the second direction and extend along the first direction.

[0070] The bottom plate 2120 is slidably mounted on the two guide rails 2130 via a slider. The output end of the first cylinder 2110 is fixedly connected to the bottom plate 2120 , and the first cylinder 2110 is configured to drive the bottom plate 2120 to move along the guide rails 2130 .

[0071] The lifting mechanism 220 is fixed on the bottom plate 2120, and includes a second cylinder 2210, a lifting plate 2220, four guide pillars 2230, four linear bearings 2240 and a movable joint 2250; wherein, a through hole is provided on the bottom plate 2120, and the piston rod of the second cylinder 2210 passes through the through hole and is connected to the lifting plate 2220 through the movable joint 2250. The movable joint 2250 is used to connect the lifting plate 2220 and the piston rod of the second cylinder 2210, so that the connection error between the lifting plate 2220 and the piston rod of the second cylinder 2210 can be eliminated, so that the lifting process is smooth and stable.

[0072] The four guide pillars 2230 are respectively located at the four corners of the base plate 2120, and the lower ends of the guide pillars 2230 are fixedly connected to the base plate 2120. Four mounting holes are provided at the four corners of the lifting plate 2220 and the guide pillars 2230 on the base plate 2120 corresponding to the four mounting holes. Four linear bearings 2240 are fixedly installed in the four mounting holes. The four guide pillars 2230 are respectively slidably connected to the four linear bearings 2240. The guide pillars 2230 move up and down with the lifting plate 2220 to play a guiding role. In addition, since the feeding mechanism 200 also needs to move horizontally under the drive of the first cylinder 2110, the piston rod of the second cylinder 2210 also needs to be subjected to horizontal force. The existence of the four guide pillars 2230 can ensure that the piston rod will not bend under the action of horizontal force.

[0073] In some embodiments, the feeding mechanism 200 also includes two beams 230 and multiple sets of support seats 240, wherein the two beams 230 are fixedly mounted on the lifting plate 2220 and extend along the first direction, and the two beams 230 are spaced apart in the second direction and located at the edge of the lifting plate 2220.

[0074] Two support seats 240 in the same group of support seats 240 are respectively installed on two beams 230 relatively along the second direction, and multiple groups of support seats 240 are arranged at intervals along the first direction. The spacing between two adjacent groups of support seats 240 is equal to the spacing between two adjacent first positioning reference blocks 3110. With such a design, the feeding mechanism 200 can simultaneously transport multiple workpieces 10 to be processed to different pre-positioning devices 310.

[0075] A positioning groove is provided on the top of the support seat 240, and the shape of the positioning groove is adapted to the shape of the workpiece 10 to be processed. In this way, the support seat 240 can play a limiting role in the first direction during the transportation of the workpiece 10 to be processed. When other workpieces 10 to be processed need to be processed, the support seat 240 can be replaced to achieve the limiting of workpieces 10 to be processed of different sizes.

[0076] The feeding process of the above-mentioned feeding mechanism is as follows: the first cylinder 2110 starts and drives the base plate 2120 to move along the guide rail 2130 toward the upper feeding area 150, so that the position of the limit groove of a group of support seats 240 close to the loading area corresponds to the workpiece 10 to be processed in the loading area 150. At this time, the second cylinder 2210 starts and drives the lifting plate 2220 together with the cross beam 230 and the support seat 240 to rise together. The support seat 240 contacts the workpiece 10 to be processed during the rising process, and the workpiece 10 to be processed is stuck in the limit groove, and the workpiece 10 to be processed is lifted until it no longer contacts the loading area 150.

[0077] Afterwards, the first cylinder 2110 drives the base plate 2120 to move downstream, transporting the workpiece 10 to be processed to the chamfering station 420, and the second cylinder 2210 drives the lifting plate 2220 to descend, and the workpiece 10 to be processed falls into the groove of the first positioning reference block 3110. The fixing mechanism 300 fixes the workpiece 10 to be processed, and then the workpiece 10 is processed by the processing device 410.

[0078] During the processing, the first cylinder 2110 starts and drives the base plate 2120 to move along the guide rail 2130 to the loading area 150; after the processing is completed, the pressure on the workpiece 10 to be processed is released, and the second cylinder drives the lifting plate 2220 to rise. While the workpiece 10 to be processed located at the chamfering station 420 is lifted, another workpiece 10 to be processed located in the loading area will also be lifted; the above-mentioned conveying process is subsequently repeated, and after the processing is completed at each processing station 400, the finished workpiece is conveyed to the finished product coding area 160.

[0079] The feeding mechanism 200 in the embodiment of the present application enables each processing station 400 to process multiple workpieces 10 to be processed at the same time, thereby improving production efficiency, and has a simple structure and strong scalability.

[0080] In some embodiments, the guide rail 2130 and the guide post 2230 are provided with a dust cover 250, which is in the shape of an accordion. The dust cover 250 can protect the guide rail 2130 and the guide post 2230 from being corroded by dust, debris, oil and other substances, thereby ensuring the cleanliness and dryness of the surfaces of the guide rail 2130 and the guide post 2230, and ensuring the processing accuracy and service life of the multi-station machining equipment. In addition, the dust cover 250 can also prevent the debris generated during the processing from splashing onto the workers, ensuring the safety of the workers.

[0081] The specific working process of the multi-station machining equipment of this application is:

[0082] The workpiece 10 to be processed is placed in the loading area 150, and the first cylinder 2110 is started to drive the base plate 2120 to move along the guide rail 2130 toward the loading area 150, so that the position of the limiting grooves of a group of support seats 240 close to the loading area corresponds to the workpiece 10 to be processed in the loading area 150. At this time, the second cylinder 2210 is started to drive the lifting plate 2220 together with the cross beam 230 and the support seat 240 to rise together. The support seat 240 contacts the workpiece 10 to be processed during the rising process, and the workpiece 10 to be processed is stuck in the limiting groove, and the workpiece 10 to be processed is lifted until it is no longer in contact with the loading area 150.

[0083] Afterwards, the first cylinder 2110 drives the base plate 2120 to move downstream. During this process, the baffle 3130 adjusts the position of the workpiece 10 to be processed in the second direction, and transports the workpiece 10 to be processed to the chamfering station 420. The second cylinder 2210 drives the lifting plate 2220 to descend, and the workpiece 10 to be processed falls into the groove of the first positioning reference block 3110. The first positioning reference block 3110 and the second positioning reference block 3120 cooperate to achieve pre-positioning of the workpiece 10 to be processed in the first direction, the second direction and the third direction.

[0084] The clamping device 320 then clamps the workpiece 10 to be processed after being pre-positioned by the pre-positioning device 310. Specifically, the connecting rod clamping cylinder 3211 is started, and the output end of the connecting rod clamping cylinder 3211 pushes the first connecting rod 3213 and then pushes the second connecting rod 3214 to move. The first clamping block 3212 makes a circular motion with the connecting axis between its second end and the first positioning reference block 3110 as the center. In this way, the first positioning reference block 3110 contacts two surfaces of the workpiece 10 to be processed, and the first clamping block 3212 contacts the other two surfaces of the workpiece 10 to be processed, thereby cooperating to fix the workpiece 10 to be processed in the first direction and the third direction.

[0085] The rotating cylinder 3221 is started, and the output end of the rotating cylinder 3221, together with the second clamping block 3222, rotates until the second clamping block 3222 is aligned with the workpiece 10 to be processed, and moves along the second direction to clamp the workpiece 10 to be processed. The second clamping device 3220 cooperates with the second positioning reference block 3120 to fix the workpiece 10 to be processed in the second direction, and after fixation, it is processed by the processing device 410.

[0086] During the processing, the first cylinder 2110 starts and drives the base plate 2120 to move along the guide rail 2130 to the loading area 150; after the processing is completed, the pressure on the workpiece 10 to be processed is released, and the second cylinder drives the lifting plate 2220 to rise. While the workpiece 10 to be processed located at the chamfering station 420 is lifted, another workpiece 10 to be processed located in the loading area will also be lifted; the above-mentioned conveying process is subsequently repeated, and after the processing at each processing station 400 is completed, the finished workpiece is conveyed to the finished product coding area 160, and the processing is completed.

[0087] With such a design, a plurality of workpieces 10 to be processed are simultaneously transported to different processing stations 400 through the feeding mechanism 200, pre-positioned by a simple pre-positioning device 310, and then fixed by a pneumatic clamping device 320 in cooperation with the pre-positioning device 310, and the fixing method is simple and reliable; different processing devices 410 process a plurality of workpieces 10 at the same time, thereby improving the processing efficiency and facilitating the production of large quantities of workpieces; the production of workpieces of different models can also be achieved by adjusting the pre-positioning device 310 and replacing the support seat 240; in addition, the entire process reduces manual participation, and no manual positioning and clamping is required, thereby reducing the probability of safety hazards.
