Technical Field

[0001] This application relates to the field of louver manufacturing technology, and in particular to a device for punching holes in louvers for ventilation windows. Background Technology

[0002] The louvers of a ventilation window can switch between ventilation and blocking modes by rotating, so a round pin needs to be inserted into one end of the louver to connect it to the window frame and enable rotation. However, the existing louver pin manufacturing process usually relies on multiple machines working together, resulting in fragmented processes and low production efficiency. Summary of the Invention

An elastic limiting device is provided at the opening of the receiving tube near the moving plate, and a telescopic push rod is provided at the opening of the receiving tube away from the moving plate. The receiving tube also has a feed inlet.

[0014] Preferably, the main frame is rotatably connected to a threaded rod, and the threaded rod is threadedly connected to two moving blocks. The two moving blocks have opposite thread directions, and the two moving blocks are respectively connected to two bearing plates. The main frame is provided with a motor connected to the threaded rod at one end corresponding to the threaded rod.

[0015] Preferably, there are two devices for drilling the center hole and two devices for inserting the pin. The two devices for drilling the center hole are symmetrically arranged on both sides of the material transport surface extension direction, and the two devices for inserting the pin are also symmetrically arranged on both sides of the material transport surface extension direction.

[0016] Preferably, the main frame is provided with a slotting device, which is symmetrically arranged on both sides of the material transport surface extension direction with the milling notch device. The slotting device includes a first guide rail, a second guide rail and a slotting drill. The extension direction of the first guide rail is parallel to the ground and perpendicular to the movement direction of the moving plate. The extension direction of the second guide rail is parallel to the ground and the same as the movement direction of the moving plate. The second guide rail is slidably connected to the first guide rail by setting a slide groove. The slotting drill is slidably connected to the second guide rail by setting a slide groove.

[0017] The main frame is equipped with a second guide rail cylinder and a slotting rodless cylinder. The moving part of the second guide rail cylinder moves in the same direction as the extension direction of the first guide rail. The moving part of the second guide rail cylinder is connected to the second guide rail.

In summary, this application includes the following beneficial technical effects: 1. It realizes fully automated flow and synchronous processing of materials between multiple workstations. The moving plate is driven by an automatic linear reciprocating drive device, which drives the pusher to push the material from the loading station to the milling notch, side hole, center hole and pin insertion stations in sequence. Each processing device can process the material located at the corresponding workstation at the same time, without the need for manual handling, which significantly improves production efficiency; 2. The push block has both unidirectional pushing and automatic obstacle avoidance functions. When the moving plate drives the push block forward, the limit block blocks the push block from rotating, achieving reliable pushing; when resetting, due to the obstruction of the pressed material, the push block can rotate in the opposite direction to bypass the material, and automatically return to the pushing posture under the action of the spring, so that the push block can achieve unidirectional feeding in reciprocating motion without additional drive; 3. The loading device enables automatic selection of stacked materials. By using a telescopic top block to lift the material in the loading space, and in conjunction with a telescopic insert block to support the second material above, the bottom layer of material falls onto the transport surface alone, realizing the automatic material distribution function of releasing only one piece of material from the stack at a time; 4. The slotting device and the gear pin insertion device work together to achieve automatic installation of special gear pins. The slotting drill first drills a hole and then moves laterally to widen the slot through the cross guide rail. Then, the gear pin insertion device, with the cooperation of the rotary cylinder and electric rotary table, completes the flipping, clamping, turning and insertion of the gear pin, which meets the installation requirements of special louvers for gear pins. 5. Adjustable spacing between bearing plates, highly adaptable. Two moving blocks with opposite thread directions are driven by a threaded rod, causing the two bearing plates to move synchronously closer or further apart along the main slide rail. This allows for flexible adjustment of the load-bearing range of the material transport surface, adapting to the processing of louvered materials of different lengths. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] The following is in conjunction with the appendix Figures 1-11 This application will be further described in detail below. An embodiment of this application discloses a device for punching holes in the louvers of a ventilation window.

[0024] The system includes a main frame 1 placed on the ground. Two parallel, symmetrically arranged support plates 101 are mounted on both sides of the main frame 1. The support surfaces of the two support plates 101 together form a material transport surface, which is parallel to the ground and extends in the same direction as the support plates 101. The distance between the two support surfaces corresponds to the length of the material 9. Each support plate 101 is connected to an automatic linear reciprocating drive device 102. The moving parts of the two automatic linear reciprocating drive devices 102 move in the same direction as the extension of the two support plates 101. Each moving part of the two automatic linear reciprocating drive devices 102 is connected to a moving plate 103, so that the moving direction of the two moving plates 103 is the same as the extension of the support plates 101.

[0025] The main frame 1 is provided with a loading device 2, a milling notch device 3, a side hole drilling device 4, a center hole drilling device 5, and a pin-threading device 6 in sequence along the extension direction of the bearing plate 101. Among them, the loading device 2, the milling notch device 3, the side hole drilling device 4, the center hole drilling device 5, and the pin-threading device 6 respectively form a loading station, a milling notch station, a side hole drilling station, a center hole drilling station, and a pin-threading station on the material transport surface, thereby determining the forward movement direction of the material 9 from the loading station to the pin-threading station, as well as the number and position of the stations where the material 9 needs to stop for processing on the material transport surface.

[0026] The main frame 1 has vertically movable telescopic blocks 105 positioned above the bearing surfaces of the two bearing plates 101, corresponding to the positions of the milling notch device 3, the side hole drilling device 4, the center hole drilling device 5, and the pin insertion device 6. That is, at the same workstation, telescopic blocks 105 are positioned above the bearing surfaces of the two bearing plates 101, so that when the material 9 is processed by the corresponding processing device at the corresponding workstation, the telescopic blocks 105 press both ends of the material 9 against the bearing surfaces of the bearing plates 101 at the corresponding device's position, thus fixing the material 9 on the material transport surface and preventing it from shaking during processing. After the material 9 is processed, the telescopic blocks 105 retract to release the pressure on the material 9, allowing it to move to the next workstation for further processing.

[0027] Two movable plates 103 are each equipped with a lever 104 at the positions corresponding to the feeding device 2, milling notch device 3, side hole punching device 4, center hole punching device 5, and pin insertion device 6. The lever 104 extends perpendicularly to the ground and is rotatably connected to the movable plate 103. The rotation axis of the lever 104 is located at the center point of its extension direction and perpendicular to the moving direction of the movable plate 103. The rotation axis of the lever 104 is lower than the bearing surface, while the end of the lever 104 away from the ground is higher than the bearing surface. This allows the lever 104 to push the material 9 on the bearing plate 101 under the drive of the movable plate 103, and also enables it to rotate around the material 9 on the bearing surface. The movable plate 103 is provided with a limiting block 108 to prevent the lever 104 from rotating. The automatic linear reciprocating drive device 102 drives the moving plate 103 to move, so that the lever 104 connected to the moving plate 103 cannot rotate forward due to the obstruction of the limit block 108. This allows the louvered material 9 placed on the material transport surface to move sequentially from the loading station to the milling notch station, the side hole drilling station, the center hole drilling station, and the pin insertion station, thus realizing the forward movement of the material 9 on the material transport surface. Except for the loading station where there is no material 9 after the material 9 has moved, during the reverse movement of the lever 104 driven by the automatic linear reciprocating drive device 102 to reset, in order to prevent the reset lever 104 from pushing the material 9 in the opposite direction, the telescopic pressure block 105 presses down on the material 9 at the corresponding station, so that the lever 104 can rotate in the opposite direction due to the obstruction of the material 9. This allows the end of the lever 104 away from the ground to be lower than the bearing surface after rotation, thus smoothly bypassing the material 9. Specifically, the limiting block 108 is located below the rotation axis of the lever 104 and within the rotation radius of the lever 104, serving to prevent the lever 104 from rotating. Simultaneously, the limiting block 108 is positioned closer to the end of the support plate 101 in the extending direction than the lever 104, ensuring that at the same workstation, the limiting block 108 is closer to the next workstation than the lever 104. This allows the limiting block 108 to prevent the lever 104 from rotating during the movement of the moving plate 103, while not preventing it from rotating during reset. To ensure that the lever 104, which rotates during reset, can also reset to a pushing state, the limiting block 108 and the end of the lever 104 closest to the ground are connected by a spring. This allows the lever 104, after passing the material 9, to be pulled by the spring and reset to a waiting-to-push posture during reset. Ultimately, this achieves the goal that, driven by the moving plate 103 and the pusher block 104, the material 9 can automatically and sequentially reach the corresponding workstation for processing, and automatically move to the next workstation after processing. Furthermore, the milling notch workstation, side hole drilling workstation, center hole drilling workstation, and pin insertion workstation are set sequentially, ensuring a continuous flow of material 9 to the corresponding workstations. The pusher block 104 can then uniformly drive all the material 9 corresponding to each workstation to automatically enter the next process.

[0028] Furthermore, the loading device 2 includes two sets of limiting devices connected to the main frame 1 and corresponding to the positions of the two bearing plates 101. Each limiting device includes a support fixing plate 201 and a limiting fixing plate 202 connected to the main frame 1. A limiting movable plate 203 is provided between the support fixing plate 201 and the limiting fixing plate 202. The extension directions of the support fixing plate 201, the limiting fixing plate 202, and the limiting movable plate 203 are all perpendicular to the material transport surface and extend away from the ground. The limiting fixing plate 202 and the limiting movable plate 203 in the two sets of limiting devices together form a loading space, so that both ends of the material 9 along its length are respectively placed in the loading spaces corresponding to the two sets of limiting devices. The material 9 in the loading space moves towards the material transport surface, causing both ends of the material 9 to fall onto the bearing surfaces of the corresponding two bearing plates 101.

[0029] A limiting linear reciprocating drive device 204 is connected to the supporting fixed plate 201, and the moving part of the limiting linear reciprocating drive device 204 is connected to the limiting movable plate 203. By driving the limiting linear reciprocating drive device 204 to move the limiting movable plate 203, the distance between the limiting movable plate 203 and the limiting fixed plate 202 is changed, thereby allowing the width of the loading space to vary, and thus making it suitable for materials 9 of more different widths.

[0030] To control the amount of material 9 falling onto the material transport surface, both the limiting fixed plate 202 and the limiting movable plate 203 in the two limiting devices are equipped with telescopic inserts 205. The telescopic inserts 205 extend and retract in a direction parallel to the ground toward the loading space, thereby inserting the telescopic inserts 205 into the loading space to support the material 9 inside. Since the cross-section of the louvered material 9 is similar to an ellipse, thicker in the middle and thinner at the edges, when two materials 9 are stacked together in the loading space, there is a gap between the two sides of their cross-sections. The positions of the limiting movable plate 203 and the limiting fixed plate 202 correspond precisely to the two sides of the material 9, allowing the telescopic inserts 205 on the limiting movable plate 203 and the limiting fixed plate 202 to be inserted precisely into the stacked materials 9, within the gap between the two adjacent materials 9.

[0031] The main frame 1 is equipped with telescopic top blocks 206, the number of which is the same as the number of limiting devices. The position of the telescopic top blocks 206 corresponds to the position of the loading space and is located below the loading space. The movement direction of the telescopic top blocks 206 is perpendicular to the ground. By telescopically extending and retracting, the telescopic top blocks 206 can enter and leave the loading space in a vertical direction. Material 9 falls naturally onto the material transport surface in the loading space due to gravity. The telescopic top blocks 206 extend to a set position in the loading space, lifting material 9 from the material transport surface and causing it to return to the loading space. At this time, the telescopic insert block 205 extends, supporting the second material 9 on the telescopic top block 206. The telescopic top block 206 retracts, and the first material 9 on the telescopic top block 206 falls back onto the material transport surface, while the second material 9, originally located on the telescopic top block 206, is supported by the telescopic insert block 205 and will not fall onto the material transport surface, thereby enabling the selection of one of the material 9 stacked in the loading space. Specifically, to ensure that after the telescopic top block 206 is raised, it is precisely at the position where the telescopic insert block 205 can support the second material 9 on the telescopic top block 206, the position of the telescopic insert block 205 can be changed according to the actual situation of materials 9 with different thicknesses. For example, the telescopic insert block 205 can be slidably connected to the corresponding limiting fixing plate 202 and limiting movable plate 203, and the limiting fixing plate 202 and limiting movable plate 203 have multiple positioning holes along the length extension direction. The telescopic insert block 205 also has corresponding positioning holes, and the telescopic insert block 205 is fixed in the set position by means of a pin. Alternatively, the maximum extension distance of the telescopic top block 206 can be modified according to the fixed position of the telescopic insert block 205 and the actual situation of materials 9 with different thicknesses. Both of the above methods require manual confirmation for the first time that when the telescopic top block 206 is pushed out, the telescopic insert block 205 can support the second material 9 on the telescopic top block 206 after it extends. This allows the system to automatically select a single material 9 from the stacked materials 9 and drop it onto the material transport surface without changing the thickness of the material 9.

[0032] Furthermore, the milling notch device 3 includes a milling cutter support 301 connected to the main frame 1. The milling cutter support 301 extends perpendicular to the ground and in a direction away from the ground. A milling cutter 302 is slidably connected to the milling cutter support 301. The milling cutter support 301 is equipped with a milling cutter linear reciprocating drive device 303. The moving part of the milling cutter linear reciprocating drive device 303 is connected to the milling cutter 302, causing the milling cutter 302 to move vertically reciprocally. The milling cutter 302 cuts and grinds notches on the side of the end of the material 9 by moving up and down. During cutting and grinding, the telescopic pressure block 105 corresponding to the milling notch station presses down on the material 9 to prevent the material 9 from moving. Specifically, in order for the milling cutter 302 to cut the corresponding end of the material 9, the operator can, depending on the actual situation, either set the distance between the bearing surfaces of the two bearing plates 101 to be less than the length of the material 9, so that the end of the material 9 extends out of the bearing surface and can be cut and ground by the milling cutter 302; or excavate a special receiving area in the bearing plate 101, that is, open a groove in the bearing plate 101 to accommodate the milling cutter 302, so that the milling cutter 302 can penetrate into the bearing area of ​​the bearing surface to grind and cut the material 9 on the bearing surface; or use both methods at the same time. In order to prevent the telescopic pressure block 105 from interfering with the milling cutter 302, the pressing range of the telescopic pressure block 105 corresponding to the milling notch position should be specifically controlled. For example, the pressing range of the telescopic pressure block 105 at the milling notch position is limited to the center of the material 9, so that the sides of the material 9 can be left open for the milling cutter 302 to cut.

[0033] Furthermore, the side-hole drilling device 4 includes a side-hole drill 401 slidably connected to the main frame. The main frame 1 is equipped with a side-hole linear reciprocating drive device 402, and the moving part of the side-hole linear reciprocating drive device 402 is connected to the drill. The side-hole drill 401 is driven by the side-hole linear reciprocating drive device 402 to move towards the material 9 on the support plate 101 to drill a side hole. Specifically, the side hole is located within the notch at the milling notch station of the previous process.

[0034] Furthermore, the center hole drilling device 5 includes a center hole drilling electric drill 501 slidably connected to the main frame 1. The main frame 1 is provided with a center hole linear reciprocating drive device 502, and the moving part of the center hole linear reciprocating drive device 502 is connected to the center hole electric drill. The center hole is located at the rotation axis of the cross-section of the material 9 and is a prerequisite for the next process of threading the pin.

[0035] Furthermore, the pin-threading device 6 includes a body 601, within which a receiving tube extends through both ends. The extending direction of the receiving tube is parallel to the ground and perpendicular to the extending direction of the moving plate 103. An elastic limiting device 604 is provided at the opening of the receiving tube near the moving plate 103, and a telescopic push rod 603 is provided at the opening of the receiving tube away from the moving plate 103. The receiving tube also has an inlet 602. By connecting an external feeding device, the output port of the feeding device is connected to the inlet 602, allowing the pin to enter the receiving tube from the inlet 602. Pushed by the telescopic push rod 603, the pin enters the receiving tube from the side away from the bearing plate 101. Subsequently, the pin is pushed out from the opening of the receiving tube near the bearing plate 101 and into the center hole of the material 9 manufactured in the previous process, thus completing the pin-threading operation. The receiving tube near the support plate 101 is equipped with an elastic limiting device 604 to prevent the round pin from sliding out of the receiving tube near the support plate 101 after entering the receiving tube from the inlet 602. Specifically, based on the round pin's cylindrical shape and conical head, the elastic limiting device 604 can be configured as an elastic stop. The elastic stop has a guide surface matching the shape of the round pin's conical head. The elastic stop is connected to the body 601 via a spring, allowing it to reciprocate linearly in a direction perpendicular to the moving direction of the round pin based on the spring's elasticity. In this embodiment, the elastic limiting device 604 consists of two stops rotatably connected to the body 601. When the two stops are joined, they jointly block the receiving tube's opening. Both stops have arc-shaped grooves, which form an opening corresponding to the receiving tube's opening when the two blocks are joined. The area of ​​the opening is smaller than the cross-sectional area of ​​the round pin to block it. Both stops are equipped with a return spring connected to the body 601. By default, the pin entering the receiving tube is blocked by two stops. When the telescopic push rod 603 pushes the pin, the pin pushes open the two stops and leaves the receiving tube. After the pin leaves the receiving tube, the two stops return to their original position under the action of the return spring, blocking the opening of the receiving tube. After the pin is inserted, the finished material on the material transport surface is removed by an external gripping device or manually.

[0036] Furthermore, to accommodate materials 9 of different lengths, the spacing between the two bearing plates 101 forming the material transport surface needs to be variable. For this purpose, the main frame 1 is equipped with a main slide rail 106. The main slide rail 106 extends parallel to the ground and is perpendicular to the moving direction of the moving plate 103. Both bearing plates 101 are slidably connected to the main slide rail 106 via grooves, allowing the two bearing plates 101 to move along the main slide rail 106, thus changing the spacing between them. The main frame 1 is rotatably connected to a threaded rod 107, which is threadedly connected to two moving blocks. The threads of the two moving blocks are in opposite directions, so that when the threaded rod 107 rotates, the two moving blocks move in opposite directions. The two moving blocks are respectively connected to the two bearing plates 101. A motor connected to the threaded rod 107 is provided at one end of the main frame 1 corresponding to the threaded rod 107. The rotation of the threaded rod 107 driven by the motor enables the two moving blocks connected to the threaded rod 107 to move in opposite directions simultaneously, thereby allowing the two bearing plates 101 to move closer or further apart, so as to change the bearing range of the material transport surface and adapt to materials 9 of different lengths.

[0037] The telescopic devices or structures described in this application all involve telescopic drive devices such as cylinders or hydraulic cylinders to drive their extension and retraction. The linear reciprocating drive device described in this application can also use a telescopic drive device with cylinders or hydraulic cylinders to achieve linear reciprocating drive through extension and retraction. The difference lies in that the moving part of the telescopic drive device can move linearly and reciprocally as a whole; for example, the telescopic moving part of a cylinder can extend and retract. Linear reciprocating drive devices also include rodless cylinders and lead screw drives, which require a fixed track, with only the moving part reciprocating along the track. In this case, the fixed track cannot move, inevitably occupying space. Therefore, the linear reciprocating drive device of this application can choose a telescopic drive device, or a linear reciprocating drive device with a fixed track such as a rodless cylinder or lead screw drive, while the telescopic drive device is limited to conventional existing devices where the moving part, such as a cylinder or hydraulic cylinder, can move as a whole.

[0038] The sliding connections involved in this application all adopt the conventional arrangement of slide rails and grooves, which restricts the movement direction of the device. Specifically, the milling notch device 3 requires the milling cutter 302 to move vertically, and the slide rail in the milling notch device 3 is located on the milling notch support and extends in the same direction as the milling notch support. The slide rails corresponding to the side hole drilling device 4 and the center hole drilling device 5 are both located on the main frame 1. The extension directions of the slide rails corresponding to the side hole drilling device 4 and the center hole drilling device 5 are parallel to the ground and perpendicular to the movement direction of the moving plate 103. The side hole drilling device 4 and the center hole drilling device 5 have grooves corresponding to the slide rails, allowing the side hole drilling drill 401 and the center hole drilling drill 501 to move to the end of the material 9 for drilling.

[0039] Furthermore, typically, a single pin is sufficient to support and allow rotation of the louvered material 9 when installed in a ventilation window. However, when using materials with special support or when the material 9 is larger, resulting in a heavier louvered material 9, pins are required at both ends along its length. To address this, the main frame 1 is equipped with two center-hole drilling devices 5 and two pin-threading devices 6. These devices are symmetrically positioned on both sides of the material transport surface, ensuring that when the material 9 reaches the center-hole drilling station, both devices 5 simultaneously drill a center hole, and when it reaches the pin-threading station, both devices 6 simultaneously thread the pin. This achieves the goal of inserting pins at both ends along the length of the material 9.

[0040] Furthermore, there are special cases where a round pin is required at one end of material 9, and a special gear pin 10 is required at the other end. This special gear pin 10 includes a cylindrical pin body 1001 and a plate-shaped insert 1002. A slot corresponding to the insert 1002 needs to be opened at the end opposite to the end of material 9 where the round pin is inserted, and the gear pin 10 needs to be automatically installed onto the end of material 9. For this purpose, the main frame 1 is also equipped with a slotting device 7 and a gear pin insertion device 8. Based on the fact that this application allows for the symmetrical arrangement of two center hole drilling devices 5 and two pin insertion devices 6, and in order to utilize the existing telescopic pressure block 105 for fixing material 9, the slotting device 7, as a pre-installation device for the gear pin 10, is positioned symmetrically on the main frame 1 and the milling notch device 3; that is, the milling notch device 3 is on one side of the milling notch station, and the slotting device 7 is on the other side. The gear pin device 8 is positioned symmetrically to the main frame 1 and the side hole punching device 4, meaning that the side hole punching device 4 is located on one side of the side hole punching station, and the gear pin device 8 is located on the other side of the side hole punching station. Vertically movable telescopic blocks 105 are already provided above the bearing surfaces of the two bearing plates 101 at the corresponding positions of the milling notch station and the side hole punching station. The slot punching device 7 and the gear pin device 8 directly utilize the fixing effect of the existing telescopic blocks 105 for processing.

[0041] Furthermore, the slotting device 7 includes a first guide rail 701, a second guide rail 702, and a slotting drill 703. The first guide rail 701 extends parallel to the ground and perpendicular to the moving direction of the moving plate 103. The second guide rail 702 extends parallel to the ground and in the same direction as the moving plate 103. The second guide rail 702 is slidably connected to the first guide rail 701 via a sliding groove, and the slotting drill 703 is also slidably connected to the second guide rail 702 via a sliding groove. The main frame 1 is equipped with a second guide rail cylinder 704 and a slotting rodless cylinder 705. The moving part of the second guide rail cylinder 704 is connected to the second guide rail 702, and its moving direction is the same as the extending direction of the first guide rail 701, driving the second guide rail 702 to slide along the extending direction of the first guide rail 701. The moving part of the slotting rodless cylinder 705 moves in the same direction as the extending direction of the second guide rail 702. Specifically, the moving part of the slotting rodless cylinder 705 is equipped with an auxiliary slide rail extending in the same direction as the first guide rail 701. The slotting drill 703 is slidably connected to the auxiliary slide rail by creating a groove, so that when the second guide rail cylinder 704 drives the second guide rail 702 to move along the extension direction of the first guide rail 701, the slotting drill 703 can also slide on the moving part of the slotting rodless cylinder 705 along the extension direction of the first guide rail 701 via the auxiliary slide rail. When the moving part of the slotting rodless cylinder 705 moves, the slotting drill 703 slides on the second guide rail 702 via the auxiliary slide rail. Through the cross arrangement of the first guide rail 701 and the second guide rail 702, the slotting drill 703 can move towards the support plate 101, and after drilling a hole in the material 9, it can also move laterally to turn the drilled hole into a groove so that the insert plate 1002 of the subsequent gear pin 10 can be inserted.

[0042] Furthermore, the gear-pin device 8 includes a first slide cylinder 801, the movement direction of which is perpendicular to the ground. A rotary cylinder 802 is connected to the moving part of the slide cylinder, the axis of which is parallel to the ground. A gripper cylinder 803 is connected to the rotating part of the rotary cylinder 802, the opening of which faces upwards away from the ground. Thus, after the rotary cylinder 802 rotates 180°, the opening of the gripper part of the gripper cylinder 803 faces the ground.

[0043] The gear pin insertion device 8 also includes a second slide cylinder 804, whose movement direction is parallel to the ground and perpendicular to the movement direction of the moving plate 103. The second slide cylinder 804 is connected to an electric rotary table 805, whose axis extends in the same direction as the movement direction of the moving plate 103, and whose axis height corresponds to the position of the slotting drill 703. The electric rotary table 805 is connected to a three-jaw cylinder 806, whose clamping block moves parallel to the ground. The opening of the clamping part of the three-jaw cylinder 806 faces upwards away from the ground, and its position corresponds to the position of the clamping part of the jaw cylinder 803, such that the gear pin 10 clamped by the downward-facing jaw cylinder 803 after rotating 180° corresponds exactly to the opening of the clamping part of the three-jaw cylinder 806. The gear pin 10 is conveyed to the top of the gripper cylinder 803 via an externally set oscillating disc and other gear pin conveying mechanism, with the insertion plate 1002 of the gear pin 10 facing the gripping part of the gripper cylinder 803. The first slide cylinder 801 rises, and the gripping part of the gripper cylinder 803 clamps the insertion plate 1002. The rotary cylinder 802 rotates 180°, the first slide cylinder 801 descends, and the reversed pin 1001 falls into the opening of the gripping part of the three-jaw cylinder 806. The three-jaw cylinder 806 clamps the pin 1001, and the gripper cylinder 803 releases the insertion plate 1002 of the gear pin 10. The electric rotary table 805 rotates 90° towards the support plate 101. Based on the correspondence between the axial height of the electric rotary table 805 and the position of the slot drilling rig 703, after the gear pin 10 is rotated 90° by the electric rotary table 805, the insertion plate 1002 corresponds exactly to the position of the slot opened on the material 9. The second slide cylinder 804 moves towards the support plate 101, causing the insertion plate 1002 of the gear pin 10 to be inserted into the slot, thus completing the installation of the gear pin 10. Since the gear pin 10's posture remains fixed after the gripper cylinder 803 holds it, manual control is required to actively adjust the gear pin 10's posture when the gripper cylinder 803 holds it. This ensures the gear pin 10 is in a pre-set gripping posture when the conveying device reaches above the gripper cylinder 803.
