Description

Technical Field

[0001] The invention relates to the technical field of window pulley production, in particular to an automatic puncturing and punching device for window pulley production. Background Art

[0002] In order to meet people's pursuit of aesthetics, many large indoor windows are often installed using hanging rails. In this way, the bottom of the window does not require any tracks or grooves, and can be pushed and pulled to achieve a beautiful effect.

[0003] When assembling the window hanging rail pulley, the pulley needs to be installed on the pulley block. In order to make the pulley block meet the load-bearing capacity of large windows, a solid pulley block is often used. During production, the pulley block needs to have two openings longitudinally and one opening transversely. Then, the pulley is installed on the two longitudinal openings, and the hanging rod is installed on the transverse opening to complete the installation of the pulley. When in use, connect the top of the window with the hanging rod on the pulley block, and then install the pulley as a whole in conjunction with the aluminum alloy slide groove at the top of the window to complete the installation of the hanging window.

[0004] In order to improve the production efficiency of the pulley block, the existing automated equipment can realize automatic drilling of the pulley block. When the equipment is running, the material conveying box will first convey the un-drilled pulley block to the pushing block through the conveying channel, and then the pneumatic push rod will pass through the fixed frame to push the pulley block, so that the pulley block is temporarily clamped between the pneumatic push rod and the pushing block, and then the pushing block will continue to cooperate with the pneumatic push rod to move the pulley block to the fixed frame, and then the pulley block will be fixed between the pushing block and the fixed frame under the continuous thrust of the pushing block, and the pneumatic push rod can be withdrawn at the same time, and the drilling operation of the pulley block can be started at this time. In order to improve efficiency, the drilling adopts the method of drilling holes simultaneously by six groups of drilling rigs, in which every two groups of drilling rigs cooperate to open a through opening, so that the six groups of drilling rigs can realize the drilling of three groups of through openings on the pulley block at one time.

[0005] The above-mentioned automatic drilling equipment has certain defects when drilling holes in the pulley block. The main problem is that the pulley block needs to be continuously thrust by the pushing block during the drilling process, and the six-group drilling rig will produce large vibrations and unstable thrusts on the pulley block and the pushing block during operation. Since the pushing block is powered by a cylinder, long-term vibrations and unstable thrusts can easily cause the connection between the pushing block and the cylinder to loosen, which in turn causes the pulley block to produce displacement deviations during movement. This displacement deviation will eventually affect the accuracy of drilling on the pulley block and cause deviations in the drilling position.

[0006] In addition, part of the chips generated during the drilling process will fall into the collection box below the equipment together with the pulley block, causing the pulley block and the chips to mix, which will interfere with subsequent processing steps. Summary of the invention

[0007] The object of the present invention is to provide an automatic puncture and punching device for window pulley production, which solves the problem that the six-group drilling rig of the traditional punching device will generate large shaking force and unstable thrust on the pulley block and the pushing block when drilling, and the pushing block is a power output source through the cylinder. In the long run, the travel route of the pushing block will have displacement deviation, which will cause the pulley block to have displacement deviation when the pushing pulley block moves, and some chips generated by the wheel block will fall into the collection box under the equipment at the same time as the pulley block. In the present invention, the pulley block can be automatically fixed on the clamping assembly under the clamping and pushing of the pneumatic push rod and the pushing block, and the pushing block does not need to be in contact with it all the time. After the punching is completed, when the next pulley block is transmitted for punching, the clamping assembly will automatically open, and the punched pulley block will automatically fall, thereby realizing the continuous automation effect of the device, and the pulley block can be separated from the debris during the falling process.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] An automatic puncture and punching device for window pulley production includes a drilling machine used in conjunction with a machine tool, a material conveying box is placed next to the machine tool, a slide seat is fixedly connected to one side of the machine tool, a push block is slidably connected to the slide seat, a conveying channel is connected between the slide seat and the material conveying box, and a pneumatic push rod is installed on the other side of the machine tool. It also includes a rectangular opening opened on the machine tool, a fixed seat fixedly connected to the rectangular opening, a clamping component installed on the fixed seat, an opening and closing component installed on the clamping component, and a self-locking component installed on the clamping component. And a pulley block used in conjunction with the clamping assembly; the drilling rig is provided with a total of six groups, of which four groups are arranged in pairs with one side facing each other, and the other two groups are arranged in one group with one side facing each other, and the six groups of drilling rigs are arranged in a standard "cross" shape; when working, the pushing block will push the pulley block to clamp it and fix it on the clamping assembly. When the punching of the pulley block is completed, the moving pneumatic push rod will push the self-locking assembly to move it to release the limit on the clamping assembly. At this time, the clamping assembly will automatically pop open under the push of the opening and closing assembly, and the sliding block will also detach from the clamping assembly and fall off.

[0010] Preferably, the clamping assembly includes two groups of shaft columns fixedly connected to a fixed seat, an annular block rotatably connected to the shaft column, a clamping block fixedly connected to the annular block, a through drill hole opened on the clamping block, a notch opened on the clamping block, and a supporting block fixedly connected to the bottom of the clamping block; the clamping block and the shaft column are symmetrically arranged, and the space formed when the two groups of clamping blocks are closed matches the shape of the clamped portion of the pulley block, and when the pulley block is clamped on the clamping block, the drill rig can drill a hole in the pulley block through the through drill hole.

[0011] Preferably, one of the groups of clamping blocks is provided with two groups of through drilling holes, and the other group of clamping blocks is provided with one group of through drilling holes, and the positions of the through drilling holes correspond to the travel route of the drilling rig.

[0012] Preferably, the opening and closing assembly includes a bearing seat fixedly connected between two groups of shaft columns, a sliding column slidably connected to the bearing seat, an abutment block fixedly connected to the sliding column, an elastic member fixedly connected between the abutment block and the bearing seat, a rotating groove provided on the clamping block, and a connecting rod rotatably connected between the rotating groove and the abutment block. When the pulley block pushes the abutment block toward the direction of the shaft column, the abutment block will drive the clamping block to close through the connecting rod, thereby clamping the pulley block.

[0013] Preferably, the rotating groove is connected to the notch, the thickness of the connecting rod is equal to the height of the rotating groove, and when the clamping block is closed, the connecting rod will be completely retracted into the rotating groove.

[0014] Preferably, the self-locking assembly includes a moving block slidably connected to the shaft column, a pin fixedly connected to the bottom of the moving block, an elastic member 2 fixedly connected between the top of the moving block and the bottom of the bearing seat, and a slot opened on the annular block. When the clamping block is closed, the pin will be automatically connected to the slot under the thrust of the elastic member 2, and the clamping block will be unable to open.

[0015] Preferably, the top of the moving block is flat and the bottom of the moving block is inclined. When the pneumatic push rod passes through the moving block, the moving block will be lifted up by the bottom inclined surface of the moving block, and the latch will be disengaged from the latch, and the clamping block will automatically pop open due to the thrust of the elastic member.

[0016] Preferably, a receiving assembly is also provided at the rectangular opening; the receiving assembly includes a slide groove fixedly connected to the rectangular opening, a slider slidably connected to the slide groove, a baffle fixedly connected to the slider, a guide wheel fixedly connected to the baffle, a discharge channel fixedly connected to the baffle, and two pneumatic push rods installed between the baffle and the machine tool. When the pulley block is pushed out of the clamping block, it will abut against the guide wheel and then fall along the guide wheel and the discharge channel.

[0017] Preferably, the bottom of the baffle is also fixedly connected to a frame, the frame is fixedly connected to an elastic net, and a collection box is also provided next to the elastic net. When the pulley block falls onto the elastic net, the pulley block will be bounced into the collection box by the elastic force.

[0018] Preferably, the elastic net is made of elastic nylon material, and the elastic net is tilted. The tilted elastic net can change the moving trajectory of the sliding block, so that the sliding block is separated from the chips.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Different from the traditional punching device which needs to maintain the continuous thrust of the pushing block to meet the fixing needs of the pulley block for punching, which may easily lead to deviation of the moving trajectory of the pushing block over time, thereby leading to deviation of the punching, the present invention can make the pushing block push the pulley block to be directly clamped on the clamping assembly by setting a clamping assembly, and the clamping assembly will automatically complete the closing and locking, thereby facilitating the punching work and effectively ensuring the accuracy of the punching position of the pulley block.

[0021] 2. When the pulley block completes punching, the pneumatic push rod will move toward the pushing block and push the latch to unlock the clamping assembly. Once the lock is released, the clamping assembly will quickly release the pulley block to make it fall, and the chips on the pulley block will also be shaken off by the release force. During this process, the pneumatic push rod will continue to move toward the pushing block so as to work with the pushing block to send the next pulley block to the clamping assembly for punching. In this way, the clamping assembly achieves continuous operation and automation in the entire punching operation.

[0022] 3. When the pulley block is ejected from the clamping assembly, the debris on its surface will fall off due to shaking. Then, the pulley block is ejected into the collection box under the elastic force of the elastic net, and the debris falls directly due to gravity. This design effectively separates the pulley block from the debris. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 9 The present invention provides an automatic puncture and punching device for window pulley production, and the technical solution is as follows:

[0035] As an embodiment of the present invention, refer to Figure 2 - Figure 4 , an automatic puncture and punching device for window pulley production, including a drilling machine 2 used in conjunction with a machine tool 1, a material conveying box 11 is placed next to the machine tool 1, a slide 12 is fixedly connected to one side of the machine tool 1, a push block 13 is slidably connected to the slide 12, a conveying channel 14 is connected between the slide 12 and the material conveying box 11, and a pneumatic push rod 15 is installed on the other side of the machine tool 1, and also includes a rectangular opening 3 opened on the machine tool 1, a fixed seat 4 fixedly connected to the side of the rectangular opening 3, a clamping assembly 5 installed on the fixed seat 4, an opening and closing assembly 6 installed on the clamping assembly 5, a self-locking assembly 7 installed on the clamping assembly 5, and a pulley block 8 used in conjunction with the clamping assembly 5; the drilling machine 2 is provided with six groups in total, four of which are arranged in pairs with one side facing each other, and the other two groups are arranged in one group with one side facing each other, and the six groups of drilling machines 2 are arranged in a standard "cross" shape;

[0036] During the punching operation, the material conveying box 11 will convey the pulley block 8 to the slide seat 12 through the conveying channel 14. At this time, the pneumatic push rod 15 will pass through the clamping assembly 5 and move in the direction of the pushing block 13, squeezing the pulley block 8 between the pneumatic push rod 15 and the pushing block 13, and then the pushing block 13 will push the pulley block 8 to move in the direction of the clamping assembly 5. During the movement, the pulley block 8 will push the opening and closing parts to drive the clamping assembly 5 to close. When the closing is completed, the pulley block 8 will also be automatically clamped on the clamping assembly 5. When the punching of the pulley block 8 is completed, the pneumatic push rod 15 will repeat the previous action and move in the direction of the pushing block 13. When the moving pneumatic push rod 15 passes through the self-locking assembly 7, it will push the self-locking assembly 7 to move it to release the limit on the clamping assembly 5. At this time, the clamping assembly 5 will automatically pop open under the push of the opening and closing assembly 6, and the sliding block will also detach from the clamping assembly 5 and fall off.

[0037] As an embodiment of the present invention, refer to Figure 5 and Figure 6 The clamping assembly 5 includes two groups of shaft columns 51 fixedly connected to the fixing seat 4, an annular block 52 rotatably connected to the shaft column 51, a clamping block 53 fixedly connected to the annular block 52, a through-drilling hole 54 provided on the clamping block 53, a notch 55 provided on the clamping block 53, and a supporting block 56 fixedly connected to the bottom of the clamping block 53; the clamping block 53 and the shaft column 51 are symmetrically arranged, and the space formed between the two groups of clamping blocks 53 when closed is consistent with the shape of the clamped part of the pulley block 8. When the clamping block 53 is closed, the three corners of the pulley block 8 can be surrounded, and the bottom of the pulley block 8 will be supported by the supporting block 56, ensuring the stability of the clamping of the pulley block 8. When the pulley block 8 is clamped on the clamping block 53, the drilling rig 2 can drill the pulley block 8 through the through-drilling hole 54.

[0038] As an embodiment of the present invention, refer to Figure 6 One group of clamping blocks 53 is provided with two groups of through drilling holes 54, and the other group of clamping blocks 53 is provided with one group of through drilling holes 54, and the positions of the through drilling holes 54 correspond to the travel route of the drilling rig 2, which can ensure that the drilling rig 2 can pass through the clamping blocks 53 to drill holes in the pulley block 8.

[0039] As an embodiment of the present invention, refer to Figure 7 and Figure 5The opening and closing assembly 6 includes a bearing seat 61 fixedly connected between two groups of shaft columns 51, a sliding column 62 slidably connected to the bearing seat 61, an abutment block 63 fixedly connected to the sliding column 62, an elastic member 64 fixedly connected between the abutment block 63 and the bearing seat 61, a rotating groove 65 provided on the clamping block 53, and a connecting rod 66 rotatably connected between the rotating groove 65 and the abutment block 63. When the pulley block 8 pushes the abutment block 63 to move toward the shaft column 51, the abutment block 63 overcomes the elastic force of the elastic member 64 and approaches the bearing seat 61. At the same time, the abutment block 63 will drive the clamping block 53 to close to each other through the connecting rod 66. When the clamping block 53 is closed, the pulley block 8 will be surrounded and fixed by the clamping block 53.

[0040] As an embodiment of the present invention, refer to Figure 7 The rotating groove 65 is connected to the notch 55 , the thickness of the connecting rod 66 is equal to the height of the rotating groove 65 , when the clamping block 53 is closed, the connecting rod 66 will be completely retracted into the rotating groove 65 , and when the clamping block 53 is closed, the abutting block 63 will be located in the notch 55 .

[0041] As an embodiment of the present invention, refer to Figure 7 and Figure 8 The self-locking assembly 7 includes a moving block 71 slidably connected to the shaft column 51, a latch 72 fixedly connected to the bottom of the moving block 71, an elastic member 73 fixedly connected between the top of the moving block 71 and the bottom of the bearing seat 61, and a slot 74 opened on the annular block 52. The bottom of the latch 72 is conical to facilitate the insertion of the latch 72 and the slot 74, and the shapes of the latch 72 and the slot 74 match. When the clamping block 53 is closed, the latch 72 will be automatically inserted into the slot 74 by the thrust of the elastic member 73, and the clamping block 53 will be unable to open.

[0042] As an embodiment of the present invention, refer to Figure 7 , Figure 8 and Figure 3 The top of the moving block 71 is flat, and the bottom of the moving block 71 is inclined. When the pulley block 8 is punched, the pneumatic push rod 15 will move toward the push block 13. When the moving pneumatic push rod 15 passes through the moving block 71, it will push the moving block 71 upward through the inclined surface at the bottom of the moving block 71, thereby driving the latch 72 to disengage from the slot 74. At this time, the clamping block 53 will be pushed by the elastic member 64 to automatically pop open, and the sliding block will also detach from the clamping assembly 5 and fall off.

[0043] As an embodiment of the present invention, refer to Fig. 9A receiving assembly 9 is also provided at the rectangular opening 3; the receiving assembly 9 includes a slide groove 91 fixedly connected to the rectangular opening 3, a slider 92 slidably connected to the slide groove 91, a baffle 93 fixedly connected to the slider 92, a guide wheel 94 fixedly connected to the baffle 93, a discharge channel 95 fixedly connected to the baffle 93, and a pneumatic push rod 2 96 installed between the baffle 93 and the machine tool 1, wherein a total of four groups of guide wheels 94 are provided, and the edge of the guide wheel 94 can abut against the pushed out pulley block 8. When the push block 13 pushes the pulley block 8 to complete the movement into the slide seat 12, the pneumatic push rod 2 96 will push the baffle 93 to move upward to the level of the pulley block 8. When the pulley block 8 is pushed out of the clamping block 53, the pulley block 8 will fall along the guide wheel 94 and the discharge channel 95. After falling, the baffle 93 will be rapidly lowered by the thrust of the pneumatic push rod 2 96.

[0044] As an embodiment of the present invention, refer to Fig. 9 A frame 931 is fixedly connected to the bottom of the baffle 93, an elastic net 932 is fixedly connected to the frame 931, and a collection box 933 is arranged next to the elastic net 932. When the pulley block 8 falls onto the elastic net 932, the pulley block 8 will be bounced into the collection box 933 by the elastic force.

[0045] As an embodiment of the present invention, refer to Fig. 9 The elastic net 932 is made of elastic nylon material and is tilted. The tilted elastic net 932 can change the moving trajectory of the sliding block, so that the sliding block is separated from the chips when being bounced off by the elastic net 932.

[0046] Working principle:

[0047] Reference Figure 1 , in the existing automatic drilling equipment, the material conveying box 11 will first convey the unpunched pulley block 8 to the pushing block 13 through the conveying channel 14, and then the pneumatic push rod 15 will pass through the fixed frame to push the pulley block 8, so that the pulley block 8 is temporarily clamped between the pneumatic push rod 15 and the pushing block 13, and then the pushing block 13 will continue to cooperate with the pneumatic push rod 15 to move the pulley block 8 to the fixed frame, and then the pulley block 8 will be fixed between the pushing block 13 and the fixed frame under the continuous thrust of the pushing block 13, and the pneumatic push rod 15 can be evacuated at the same time, and the drilling rig 2 can start the drilling operation on the pulley block 8. In the prior art, under the long-term shaking and unstable thrust of the pushing block 13 caused by the drilling rig 2, the pushing block 13 is easy to loosen with the cylinder, resulting in displacement deviation in the travel route, and the chips will fall and be collected and mixed together with the pulley block 8 at the same time;

[0048] Reference Figure 2 , Figure 3 and Figure 6In the present invention, when punching the pulley block 8, the material conveying box 11 will convey the pulley block 8 to the slide seat 12 through the conveying channel 14, and at this time, the pneumatic push rod 15 will pass through the gap 55 between the clamping blocks 53 and move toward the push block 13 (at this time, the receiving component 9 is at a position lower than the top of the rectangular opening 3), and finally squeeze the pulley block 8 between the pneumatic push rod 15 and the push block 13, and then the push block 13 will push the pulley block 8 to move toward the clamping component 5;

[0049] Reference Figure 3 , Figure 5 , Figure 6 and Figure 7 , in the process of the push block 13 pushing the pulley block 8 to move, the pulley block 8 will push the abutment block 63 to move toward the shaft column 51 while moving, and the abutment block 63 will overcome the elastic force of the elastic member 1 64 to approach the bearing seat 61, and at the same time, the abutment block 63 will drive the clamping block 53 to close to each other through the connecting rod 66. When the clamping block 53 is closed, the pulley block 8 will be surrounded and fixed by the clamping block 53. After the clamping block 53 is closed, the latch 72 will be automatically plugged into the slot 74 by the thrust of the elastic member 2 73. At this time, the clamping block 53 will not be able to open, and the push block 13 will return to the slide seat 12. At this time, the baffle 93 will also be pushed out by the pneumatic push rod 2 96 to be flush with the pulley block 8. At the same time, the drill bit of the drilling rig 2 can pass through the drill hole 54 to carry out drilling operations on the pulley block 8;

[0050] Reference Figure 7 - Fig. 9 When the punching of the pulley block 8 is completed, the pneumatic push rod 15 will continue to move toward the push block 13 to prepare for the punching operation of the next pulley block 8. When the moving pneumatic push rod 15 passes the moving block 71, it will push the moving block 71 upward through the inclined surface at the bottom of the moving block 71, thereby driving the latch 72 to disengage from the slot 74. At this time, the clamping block 53 will be automatically ejected by the thrust of the elastic member 64, and the pulley block 8 will also be pushed out of the clamping block 53. When the pulley block 8 is pushed out of the clamping block 53, it will fall along the guide wheel 94 and the discharge channel 95, and finally fall onto the elastic net 932. Then, under the elastic force of the elastic net 932, the pulley block 8 will be ejected into the collection box 933, and the chips will fall vertically, thereby realizing the separation of the pulley block 8 and the chips.
