Description

Technical Field

[0001] The utility model relates to the field of numerical control driving devices, in particular to a numerical control driving device for a plate shearing machine. Background Technique

[0002] A plate shearing machine is a mechanical device that uses a moving upper blade and a fixed lower blade to apply a shearing force to a metal plate through a reasonable blade gap, so that the plate breaks and separates. The plate shearing machine is widely used in the metal processing industry. It can cut the blank of the plate with a straight edge and ensure the straightness and parallelism requirements of the shearing surface. During the use of the plate shearing machine, a numerical control driving device is required for assistance.

[0003] In the existing numerical control driving device for a plate shearing machine, mainly an engine drives a curved panel to rotate. Two fixed blocks are clamped on one side of the curved panel. The rotation of the curved panel drives the fixed blocks to move, so that the blade reciprocates to achieve the shearing effect.

[0004] However, in the existing numerical control driving device for a plate shearing machine, the assembly for installing the fixed blocks is prone to flipping, reducing the clamping ability of the fixed blocks on the curved panel. Moreover, the curved panel is clamped by the fixed blocks, and the friction between the two is large, affecting the normal use of the device. Content of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide a numerical control driving device for a plate shearing machine to solve the technical problems of insufficient clamping ability and large friction between the fixed blocks and the curved panel.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A numerical control driving device for a plate shearing machine, including a housing. A chute is opened on one side of the housing. And a first partition and a second partition are arranged inside the housing. And a plurality of through holes are opened in both the first partition and the second partition. A limiting rod is installed at the top of the first partition and the bottom of the second partition. And a rotating rod is sleeved inside the limiting rod. One end of the rotating rod is installed with a motor. And a curved panel is fixed on the rotating rod. A sleeve is installed at the top of the second partition. A moving rod is sleeved inside the sleeve. A second limiting ring is installed at one end of the moving rod. A cutting rod is arranged on one side of the moving rod. One end of the cutting rod is movably connected with a cutter. A plurality of sliding rods are connected inside the moving rod through threads. A first limiting ring is installed at one end of the sliding rod.

[0007] By adopting the above technical solutions, the problems of insufficient clamping ability and large friction between the fixed block and the curved panel are solved. By setting the moving rod as a rectangle and sleeving it in the rectangular through holes inside the first partition and the second partition, the moving rod can be limited in position without affecting its movement, preventing it from rotating and affecting the clamping effect of the device. Moreover, a second limit ring is installed at one end of the moving rod and sleeved inside the sleeve to prevent the moving rod from falling and affecting the use of the device.

[0008] The utility model is further configured such that a transmission ball is sleeved on the sliding rod.

[0009] By adopting the above technical solutions, direct contact between the sliding rod and the curved panel is avoided, thereby preventing damage to the device.

[0010] The utility model is further configured such that the distance between the transmission balls sleeved on the sliding rod is the same as the thickness of the curved panel.

[0011] By adopting the above technical solutions, the curved panel can be clamped by the transmission balls, and the distance between the transmission balls is the same as the thickness of the curved panel, preventing the curved panel from being unstable during clamping and affecting the transmission efficiency.

[0012] The utility model is further configured such that the moving rod is rectangular.

[0013] By adopting the above technical solutions, the moving rod is limited in position, preventing it from flipping during transmission and causing damage to the device.

[0014] The utility model is further configured such that one end of the sliding rod is provided with threads, and a fixing nut is sleeved on the end of the sliding rod, and the sliding rod is fixed to the moving rod through the fixing nut.

[0015] By adopting the above technical solutions, the moving rod and the sliding rod can be fixed through the fixing nut, and the sliding rods are connected through the fixing nut, facilitating the disassembly and replacement of the transmission balls.

[0016] The utility model is further configured such that the curved panel is fixed to the rotating rod, and both ends of the curved panel are in contact with the limiting rod.

[0017] By adopting the above technical solutions, the curved panel can be rotated by the motor, and the curved panel can be limited through the rotating rod to ensure the effective transmission of the device.

[0018] The utility model is further configured such that the diameter of the first limit ring is smaller than the diameter of the transmission ball.

[0019] By adopting the above technical solutions, when not affecting the limiting function of the first limit ring, its diameter is reduced to avoid direct contact with the curved panel and prevent damage to the curved panel after increasing the friction force.

[0020] In summary, the utility model mainly has the following beneficial effects:

[0021] 1. By providing a first partition board, a second partition board, a sleeve, a moving rod, a sliding rod, a limiting rod, a curved panel and a rotating rod, the utility model solves the problems of insufficient clamping ability and large friction between the fixed block and the curved panel. By setting the moving rod as a rectangle and sleeving it in the rectangular through holes inside the first partition board and the second partition board, the moving rod can be limited without affecting its movement, preventing it from rotating and affecting the clamping effect of the device. Moreover, a second limiting ring is installed at one end of the moving rod, which is sleeved inside the sleeve to prevent the moving rod from falling and affecting the use of the device.

[0022] 2. By sleeving a sliding rod on one side of the moving rod, a transmission ball is sleeved on the sliding rod, and the length of the sliding rod is slightly greater than that of the transmission ball, ensuring that the transmission ball can rotate on the sliding rod. By clamping the curved panel with two groups of transmission balls, the friction between the transmission ball and the curved panel is reduced under the condition of ensuring the unchanged use ability of the device, and the service life of the device is prolonged.

A plurality of sliding rods 8 are connected inside the moving rod 7 by threads, and a first limiting ring 82 is installed at one end of the sliding rod 8.

[0034] Please refer to Figure 5 , a transmission ball 9 is sleeved on the sliding rod 8. By means of the transmission ball 9, direct contact between the sliding rod 8 and the curved panel 11 is avoided, thereby preventing damage to the device.

[0035] Please refer to Figure 3 , the distance between the transmission balls 9 sleeved on the sliding rod 8 is the same as the thickness of the curved panel 11. The curved panel 11 can be clamped by the transmission balls 9. The distance between the transmission balls 9 is the same as the thickness of the curved panel 11, avoiding instability of the curved panel 11 during the clamping process and affecting the transmission efficiency.

[0036] Please refer to Figure 2 and Figure 5 , the moving rod 7 is rectangular to limit the moving rod 7 and prevent the moving rod 7 from flipping during the transmission process, causing damage to the device.

[0037] Please refer to Figure 5 , one end of the sliding rod 8 is provided with threads, and a fixing nut 81 is sleeved at the end of the sliding rod 8. The sliding rod 8 is fixed to the moving rod 7 by the fixing nut 81.
