[0015] Beneficial effects of the present invention:

[0016] 1. The present invention does not require manual movement of the channel steel, which saves time and effort, and can ensure that the channel steel moves in a straight line, thereby improving the punching quality.

[0017] 2. The function of the bracket is to facilitate the setting of the clamping mechanism on the top and the horizontal moving mechanism on the bottom. When drilling holes in the channel steel, the clamping mechanism is used to position the channel steel to prevent the channel steel from being displaced during the processing process, causing the problem of inaccurate drilling positioning. Under the action of the horizontal moving mechanism, the steel channel moves toward the drilling head, and no manual feeding is required, saving time and effort. The function of the support plate is to support the channel steel. Because the support plate is fixed on the moving block, the support plate moves with the movement of the moving block, and the movement of the support plate drives the feeding of the channel steel. The function of setting the positioning mechanism is to ensure that the channel steel is fed with the movement of the support plate. The function of the load-bearing frame is to set the punching head. On the other hand, a limit mechanism is set. The function of the limit mechanism is to further ensure that the channel steel moves in a straight line.

[0018] 3. The base plate is used to be fixedly connected to the bracket, the clamping assembly A is used to clamp one airfoil surface of the channel steel, the clamping assembly B is used to clamp the other airfoil surface of the channel steel, the rack and pinion transmission mechanism A drives the clamping assembly A to move in the reverse direction, and the rack and pinion transmission mechanism B drives the clamping assembly B to move in the reverse direction.

[0019] 4. Take the position of cylinder A as the left side of the base plate as an example to explain the working principle of the clamping assembly of the present invention: start cylinder A to ensure that the piston rod of cylinder A extends to the right side of the base plate. The piston rod of cylinder A extends, thereby driving rack A to move to the right side of the base plate. Rack A meshes with gear A, so gear A rotates on the fixed axis. Rack A extends through connecting block A and then drives base A to move to the right on the guide rail. The movement of base A then drives clamp block B to move to the right side of the base plate. Therefore, rack A and rack B are set on both sides of gear A, so the movement directions of rack A and rack B are opposite. When rack B moves to the right side of the base plate, rack B moves to the left side of the base plate under the drive of gear A, thereby causing the distance between clamp block B and clamp block A to increase. This process is to release the channel steel.

[0020] 5. The belt transmission mechanism drives the screw to rotate, and under the limit of the guide rod, the moving block moves linearly along the axis of the screw. The belt transmission mechanism drives the screw to rotate, and under the limit of the guide rod, the moving block moves linearly along the axis of the screw.

[0021] 6. Rotate the pin, and the pin moves toward the support plate position in the threaded hole. When the lower end of the pin passes through the support plate and abuts against the wing surface of the channel steel, the channel steel can be locked to ensure that the channel steel and the support plate move synchronously.

[0022] 7. The purpose of setting cross arms and cross plates is to ensure that the channel steel moves in a straight line. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

Clamping mechanisms 2 are arranged at both ends of the bracket 1. The clamping mechanism 2 is arranged at the top of the bracket 1. When drilling holes in the channel steel, the clamping mechanism is used to position the channel steel to prevent the channel steel from being displaced during the processing process, resulting in inaccurate drilling positioning.

Because the pallet is fixed on the moving block, the pallet moves with the movement of the moving block, and the movement of the pallet drives the channel steel to feed. The role of setting the positioning mechanism is to ensure that the channel steel is fed with the movement of the pallet. A load-bearing frame 6 is provided on the bracket 1, and the function of the load-bearing frame is to set the punching head. On the other hand, a limiting mechanism is provided. A limiting mechanism 7 is provided at the bottom of the load-bearing frame 6. The role of the limiting mechanism is to further ensure that the channel steel moves in a straight line. A punching head 8 is provided on the upper part of the load-bearing frame 6. The punching mechanism is used to drill holes in the channel steel. The punching head is a prior art and will not be described here.

[0035] See also Figure 2 The clamping mechanism 2 includes a base plate 21, which is used to be fixedly connected to the bracket. A clamping assembly A22 is arranged on the rear side of the base plate 21, and the clamping assembly A is used to clamp one airfoil surface of the channel steel.

[0036] See also Figure 4 A fixed shaft 26 is provided on the bottom plate 21, a gear A27 and a gear B28 are provided on the fixed shaft 26, the gear A27 is provided on the upper end of the gear B28, two guide rails 29 are symmetrically provided on both sides of the bottom plate 21, the clamping assembly A22 is provided on the guide rail at the rear side of the bottom plate 21, and the clamping assembly B23 is provided on the guide rail at the front side of the bottom plate 21. The guide rail has the function of limiting and guiding.

[0037] See also Figure 3The clamping assembly A22 includes a clamping block A221 and a clamping block B222. A support plate A is provided at the bottom of the clamping block A and the clamping block B. The gear rack transmission mechanism A24 includes a cylinder A241. The cylinder seat of the cylinder A241 is fixedly connected to the bottom plate. A rack A242 is provided on the piston rod of the cylinder A241. The rack A242 is meshed with one side of the gear A27. A connecting block A243 is provided at the end of the rack A242. A base A244 is provided on the connecting block A243. The base A2 A groove A is provided at the bottom of 44, a guide rail on the rear side of the bottom plate is provided in the groove A, a clamping block B222 is provided at the rear side of the base A244, a rack B245 is provided at the other side of the gear A27, the rack B245 is meshed with the gear A27, a connecting block B246 is provided on the rack B245, the connecting block B246 is provided on the base B247, a groove B is provided at the bottom of the base B247, the guide rail on the rear side of the bottom plate is provided in the groove B, and a clamping block A221 is provided at the rear side of the base B247.

[0038] Taking the position of cylinder A as the left side of the base plate as an example, the working principle of the clamping assembly of the present invention is explained: start cylinder A to ensure that the piston rod of cylinder A extends to the right side of the base plate, the piston rod of cylinder A extends, and then drives rack A to move to the right side of the base plate, rack A meshes with gear A, so gear A rotates on the fixed axis, rack A extends through connecting block A and then drives base A to move to the right on the guide rail, the movement of base A drives clamping block B to move to the right side of the base plate.

[0039] Therefore, rack A and rack B are arranged on both sides of gear A, so the movement directions of rack A and rack B are opposite. When rack B moves to the right side of the base plate, rack B moves to the left side of the base plate under the drive of gear A, thereby causing the distance between clamp block B and clamp block A to increase. This process is to release the channel steel.

[0040] See also Figure 4 The clamping assembly B23 includes a clamping block C231 and a clamping block D232. The bottom of the clamping block C and the clamping block D are provided with a support plate B. The gear rack transmission mechanism B25 includes a cylinder B251. The cylinder seat of the cylinder B251 is fixedly connected to the bottom plate. The piston rod of the cylinder B251 is provided with a rack C252. The rack C252 is meshed with one side of the gear B28. The end of the rack C252 is provided with a connecting block C253. The connecting block C253 is provided with a base C254. The base C2 A groove C is provided at the bottom of 54, a guide rail on the front side of the bottom plate is provided in the groove C, a clamping block D232 is provided at the rear side of the base C254, a rack D255 is provided at the other side of the gear B28, the rack D255 is meshed with the gear B28, a connecting block D256 is provided on the rack D255, the connecting block D256 is provided on the base D257, a groove D is provided at the bottom of the base D257, the guide rail on the rear side of the bottom plate is provided in the groove D, and a clamping block C231 is provided at the rear side of the base D257.

[0041] The working principle of the clamping assembly B is the same as that of the clamping assembly A. In order to ensure that the two airfoil surfaces of the channel steel can be clamped synchronously, cylinder A and cylinder B need to be started synchronously.

[0042] See also Figure 5 The horizontal moving mechanism 3 includes a base plate 31, a frame A32 is arranged at one end of the base plate 31, a frame B33 is arranged at the other end of the base plate 31, a lead screw 34 is arranged between the frame A32 and the frame B33, a guide rod 35 is arranged at the bottom of the lead screw 34, a moving block 36 is arranged on the lead screw 34, and an internal thread corresponding to the external thread of the lead screw is arranged on the moving block. The bottom of the moving block 36 is arranged on the guide rod 35, and a belt transmission mechanism 37 is arranged at one end of the lead screw 34, and the belt transmission mechanism 37 drives the lead screw 34 to rotate.

[0043] The belt transmission mechanism drives the lead screw to rotate, and under the limitation of the guide rod, the moving block moves linearly along the axial direction of the lead screw.

[0044] See also Figure 6 The belt transmission mechanism 37 includes a motor 371, a synchronous pulley A372 is arranged on the output shaft of the motor 371, a synchronous pulley B373 is arranged on the lead screw 34, and a synchronous belt 374 is arranged on the synchronous pulley B373 and the synchronous pulley A372.

[0045] The output shaft of the motor rotates, driving the synchronous pulley A to rotate. Under the action of the synchronous belt, the synchronous pulley B rotates, which in turn drives the screw to rotate. Because the moving block is provided with an internal thread corresponding to the external thread of the screw, the output shaft of the motor rotates, driving the screw to rotate, and then driving the moving block to perform linear motion.

[0046] See also Figure 7 and Figure 8 The positioning mechanism 5 includes a fixing bar 51, on which a pin 52 is arranged, and the pin 52 includes an upper end and a lower end, and the diameter of the upper end of the pin is larger than the diameter of the lower end of the pin, and a threaded hole is arranged on the fixing bar 51, and an external thread is arranged on the upper end of the pin, and the upper end of the pin is arranged in the threaded hole, and the support plate 4 is arranged on the moving block 36, and through holes are arranged on both sides of the support plate 4, and the lower end of the pin is arranged in the through holes, and a spring 53 is arranged on the lower end of the pin, and the spring 53 is arranged between the support plate 4 and the bottom surface of the upper end of the pin.

[0047] The pin is rotated and moves in the threaded hole toward the support plate. When the lower end of the pin passes through the support plate and abuts against the wing surface of the channel steel, the channel steel can be locked to ensure synchronous movement of the channel steel and the support plate.

[0048] See also Fig. 9The limiting mechanism 7 includes two cross arms 61 symmetrically arranged at the bottom of the load-bearing frame 6 , and a cross plate 62 is arranged on the cross arm 61 . The distance between the two cross arms 61 is equal to the distance between the outer sides of the two airfoil surfaces of the steel groove 9 .

[0049] The purpose of setting cross arms and cross plates is to ensure that the channel steel moves in a straight line.

[0050] The use process of the present invention comprises the following steps:

[0051] Step 1: Start cylinder A and cylinder B at the same time, ensure that the distance between clamp block A and clamp block B and the distance between clamp block C and clamp block D are greater than the distance between the outer sides of the two wing surfaces of the channel steel, and close cylinder A and cylinder B;

[0052] Step 2: Push one end of the channel steel through the gap between the two horizontal plates at the bottom of the load-bearing frame to the position of the support plate, ensuring that one end of the channel steel is flat on the support plate, and then place the other end of the channel steel on the support plate A between the clamping blocks A and B and the support plate B between the clamping blocks C and D;

[0053] Step 3: Tighten the pins to ensure that the pins lock the channel steel on the pallet;

[0054] Step 4: Start the motor, and the moving block drives the support plate to move toward the punch head. Because the channel steel is fixed on the support plate, the channel steel moves toward the punch head.

[0055] Step 5: Start cylinder A and cylinder B synchronously in the opposite direction, ensure that clamp A is close to clamp B, and ensure that clamp C is close to clamp D, finally clamp the channel steel by clamp A and clamp B, and clamp C and clamp D, and close cylinder A and cylinder B;

[0056] Step 6: Start the drilling rig joint and drill holes in the channel steel;

[0057] Step 7: After the drilling is completed, start cylinder A and cylinder B synchronously in the opposite direction, release the channel steel, close cylinder A and cylinder B, and start the motor again to ensure that the support plate drives the channel steel to continue to move toward the drilling rig head for the next drilling;

[0058] Step 8: After the entire channel steel is punched, rotate the pin in the opposite direction and start cylinder A and cylinder B again to remove the punched channel steel to complete the entire punching process.
