Description

Technical Field

[0001] This utility model relates to the field of punching fixture technology, specifically to a plate punching fixture. Background Technology

[0002] Plate punching fixtures are devices mainly used for punching holes in single-channel plates, double-channel plates, corrugated plates, or steel plates, wood plates, and other plate materials in heat exchangers. Punching refers to the process of using a punching head to apply pressure to deform the material and create the required holes. Punching facilitates the positioning and fixing of plate materials during installation and disassembly. Due to its flexibility and efficiency, punching technology has been widely used in industrial, construction, and agricultural fields.

[0003] Currently, existing punching fixtures lack a structure that uses chain drive to smoothly transmit punching components and do not have the function of providing feed force to punching components, resulting in poor punching effect. To address this, we propose a plate punching fixture. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a plate punching fixture. This new model has a structure that uses chain drive to smoothly transmit the punching parts and can provide feed force to the punching parts, thereby effectively improving the punching effect.

[0005] The technical solution adopted by this utility model to solve its technical problem is a plate punching fixture, including a mounting plate, a transmission assembly and a feeding assembly. A connecting plate is provided on one side of the mounting plate, and a transmission assembly is provided on one side of the connecting plate. The transmission assembly includes a stepper motor, a driving gear, a first connecting rod, a driven gear and a transmission chain. The stepper motor is mounted on one side of the mounting plate by a first clamp and screws. The output end of the stepper motor is connected to the driving gear. A first connecting rod is provided at one end of the stepper motor. The top of the first connecting rod is connected to the driven gear. A transmission chain is sleeved around both the driving gear and the driven gear.

[0006] A feeding assembly is provided between the transmission assembly and the mounting plate. The feeding assembly includes an electric push rod and a second connecting rod. The electric push rod is mounted on the top of the mounting plate via a fixing plate. The output end of the electric push rod is connected to the second connecting rod. A punch head is connected to the bottom of the second connecting rod. A first slider is provided on one side of the connecting plate. A second slider is provided on both sides of the first slider on one side of the connecting plate. A first groove is formed on one side of the mounting plate. A second groove is formed on both sides of the first groove on one side of the mounting plate.

[0007] By adopting the above technical solution, the electric push rod can drive the drive gear to rotate, and then the drive gear can drive the driven gear to rotate through the transmission chain. The driven gear drives the first connecting rod and the punching head to rotate, thus providing rotational force to the punching head.

[0008] The electric push rod can drive the first and second sliders to slide through the second connecting rod, thereby providing a feed force to the punch head. Combined with the rotational force provided to the punch head by the transmission assembly, the plate can be punched.

[0009] Specifically, the mounting plate has a base at its bottom, and a support platform is provided on the top of the base on one side of the mounting plate. The top of the support platform is provided with an anti-slip pad, which is made of nitrile rubber.

[0010] Specifically, the feeding assembly also includes a circular connecting plate, which is located at the bottom of the second connecting rod and is connected to the first slider by screws.

[0011] Specifically, the No. 1 connecting rod is connected to the connecting plate by the No. 2 clamp and screws, and the No. 2 clamp has a bearing inside.

[0012] By adopting the above technical solution, the No. 2 clamp can detachably connect the No. 1 connecting rod at the top of the punch head to the connecting plate, and the bearing inside the No. 2 clamp can facilitate the rotation of the No. 1 connecting rod.

[0013] Specifically, one side of the first slider is located inside the first groove.

[0014] By adopting the above technical solution, when the first slider is driven by the electric push rod, the first slider can slide smoothly along the trajectory of the first slide groove, which facilitates the smooth sliding of the connecting plate, transmission components and punching head.

[0015] Specifically, one side of the second slider is located inside the second groove.

[0016] The beneficial effects of this utility model are:

[0017] (1) The plate punching fixture described in this utility model has an electric push rod that can drive the drive gear to rotate, and then the drive gear can drive the driven gear to rotate through the transmission chain. The driven gear drives the first connecting rod and the punching head to rotate, which can provide rotational force for the punching head.

[0018] (2) The plate punching fixture of the present invention can be used to drive the first slider and the second slider to slide through the second connecting rod, thereby providing a feed force to the punching head. Combined with the rotational force provided to the punching head by the transmission component, the plate can be punched. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] To provide rotational and feed forces to the punching components and improve the punching effect, such as Figure 1-4 As shown, the present invention provides a plate punching fixture, comprising a mounting plate 1, a transmission assembly 2, and a feeding assembly 3. A connecting plate 5 is provided on one side of the mounting plate 1, and the transmission assembly 2 is provided on one side of the connecting plate 5. The transmission assembly 2 includes a stepper motor 201, a drive gear 202, a first connecting rod 203, a driven gear 204, and a transmission chain 205. The stepper motor 201 is mounted on one side of the mounting plate 1 via a first clamp 12 and screws. The output end of the stepper motor 201 is connected to the drive gear 202. One end of the stepper motor 201 is provided with a first connecting rod 203, and the top of the first connecting rod 203 is connected to the driven gear 204. A transmission chain 205 is fitted around both the drive gear 202 and the driven gear 204.

[0027] A feeding assembly 3 is provided between the transmission assembly 2 and the mounting plate 1. The feeding assembly 3 includes an electric push rod 301 and a second connecting rod 302. The electric push rod 301 is mounted on the top of the mounting plate 1 through a fixing plate. The output end of the electric push rod 301 is connected to the second connecting rod 302. The bottom of the second connecting rod 302 is connected to a punch head 4. A first slider 6 is provided on one side of the connecting plate 5. A second slider 7 is provided on both sides of the first slider 6 on one side of the connecting plate 5. A first groove 8 is opened on one side of the mounting plate 1. A second groove 14 is opened on both sides of the first groove 8 on one side of the mounting plate 1.

[0028] In use, the electric push rod 301 can drive the drive gear 202 to rotate, and then the drive gear 202 can drive the driven gear 204 to rotate through the transmission chain 205. The driven gear 204 drives the first connecting rod 203 and the punching head 4 to rotate, thus providing rotational force to the punching head 4.

[0029] The electric push rod 301 can drive the first slider 6 and the second slider 7 to slide through the second connecting rod 302, thereby providing a feed force to the punch head 4. Combined with the rotational force provided by the transmission component 2 to the punch head 4, the plate can be punched.

[0030] For example, such as Figure 1 As shown, a base 10 is provided at the bottom of the mounting plate 1, and a support platform 9 is provided on the top of the base 10 on one side of the mounting plate 1. An anti-slip pad 11 is provided on the top of the support platform 9, and the anti-slip pad 11 is made of nitrile rubber material.

[0031] When in use, the support platform 9 makes it easy for personnel to place the plates to be punched, and the anti-slip pad 11 can increase the friction between the plate and the support platform 9, thus playing an anti-slip role.

[0032] For example, such as Figure 3 As shown, the feed assembly 3 also includes a circular connecting plate 303, which is disposed at the bottom of the second connecting rod 302 and is connected to the first slider 6 by screws.

[0033] In use, the second connecting rod 302 can be detachably connected to the first slider 6 by means of a circular connecting plate 303 and screws.

[0034] For example, such as Figure 1 , Figure 4 As shown, the first connecting rod 203 is connected to the connecting plate 5 by the second clamp 13 and screws, and the second clamp 13 is provided with a bearing 15 inside.

[0035] In use, the No. 2 clamp 13 can detachably connect the No. 1 connecting rod 203 at the top of the punch head 4 to the connecting plate 5, and the bearing 15 inside the No. 2 clamp 13 can facilitate the rotation of the No. 1 connecting rod 203.

[0036] For example, such as Figure 1 , Figure 3 As shown, one side of the first slider 6 is located inside the first groove 8.

[0037] When in use, when the first slider 6 is driven by the electric push rod 301, the first slider 6 can slide smoothly along the trajectory of the first slide groove 8, which facilitates the smooth sliding of the connecting plate 5, the transmission component 2 and the punching head 4.

[0038] For example, such as Figure 1 , Figure 3 As shown, one side of the second slider 7 is located inside the second groove 14.

[0039] In use, there are two sets of slider 7 and slide 14, which can help slider 6 slide more smoothly.

[0040] In use, the operator places the plate to be punched on the top of the support platform 9, with the plate below the punching head 4. The electric push rod 301 in the transmission assembly 2 can drive the drive gear 202 to rotate. Through the transmission chain 205, the drive gear 202 can drive the driven gear 204 to rotate, which in turn drives the first connecting rod 203 and the punching head 4 to rotate, thus providing rotational force to the punching head 4.

[0041] Furthermore, the electric push rod 301 in the feed assembly 3 can drive the first slider 6 to slide through the second connecting rod 302. With the assistance of the second slider 7, the connecting plate 5, the transmission assembly 2 and the punching head 4 can all slide smoothly, thereby providing a feed force to the punching head 4. Combined with the rotational force provided by the transmission assembly 2 to the punching head 4, the plate at the top of the support platform 9 can be punched.
