Description

Technical Field

[0001] The utility model relates to the technical field of processing a buffer roller shaft, in particular to a positioning tool for processing and punching a buffer roller shaft. Background Art

[0002] The buffer roller shaft is a device used in the conveyor belt system, usually used in the turning point or the place where buffering is needed in the material conveying line. It consists of a metal shaft supported by a bearing and a buffer wheel made of rubber or polyurethane on the periphery. When the material passes through the conveyor belt system and reaches the buffer roller shaft, the buffer wheel on the shaft can slow down the speed of the material, while reducing the impact and wear on the conveyor belt, protecting the conveyor belt system and the material. The use of the buffer roller shaft can effectively reduce the loss during transportation, extend the service life of the conveyor belt, and improve the conveying efficiency.

[0003] At present, when processing the buffer roller shaft, it is necessary to punch holes at both ends thereof. During the punching operation, the buffer roller shaft needs to be fixed using a positioning tool. However, after punching a hole at one end of the buffer roller shaft, it needs to be removed and reversed to be re-fixed before punching the other end. This is not only cumbersome to operate, increases the labor intensity of workers, and reduces processing efficiency, but also after reinstallation, it is difficult to ensure the consistency of the punching positions at both ends, thereby affecting product quality. Utility Model Content

[0004] The utility model aims to provide a positioning tool for processing and punching a buffer roller shaft, which can reduce labor intensity, improve processing efficiency, and improve the consistency of punching positions at both ends.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A positioning tool for processing and punching a buffer roller shaft comprises a bottom plate, a sliding seat is slidably mounted on the upper surface of the bottom plate along its length direction, two U-shaped plates are mounted on the upper surface of the sliding seat through a clamping mechanism, and a Y-shaped bracket is mounted on the upper surface of the U-shaped plate. Insertion blocks are mounted on both sides of the sliding seat in the length direction, and slots are provided on the upper surfaces of the insertion blocks. Connecting blocks are mounted on both sides of the upper surface of the bottom plate through an adjustment mechanism, and the connecting blocks are matched with the insertion blocks. A fixing mechanism that plugs into and matches the slots is provided on the connecting blocks.

[0007] It can be seen that, through the setting of the clamping mechanism, the two Y-shaped brackets can be driven to clamp the two ends of the buffer roller shaft to achieve the purpose of rapid fixation. After a hole is punched at one end of the buffer roller shaft, the sliding seat can be pushed to slide to the other side. Through the setting of the fixing mechanism, the sliding seat can be automatically fixed so that the other end of the buffer roller shaft is under the drill bit, thereby eliminating the need for the tedious operation of removing the buffer roller shaft and turning it around to re-fix it, reducing the labor intensity of workers and improving processing efficiency. The buffer roller shaft is always in a fixed state, thereby ensuring the consistency of the punching positions at both ends and improving product quality. Through the setting of the adjustment mechanism, it can be suitable for punching holes in buffer roller shafts of different lengths, and has a wide range of applications.

[0008] Furthermore, the clamping mechanism includes two mounting grooves A opened on the outer surface of the sliding seat, and the interiors of the two mounting grooves A are rotatably connected to threaded rods A with a pair of reverse threads, and two nut seats A are installed on the reverse threads of the threaded rods A, and the two ends of the U-shaped plate are respectively connected to the nut seats A on both sides, one end of the two threaded rods A passes through the outside of the sliding seat and is transmitted with a pulley group, and a handwheel A is rotatably installed on the side of the sliding seat away from the pulley group, and the handwheel A is connected to the other end of one of the threaded rods A.

[0009] When fixing the buffer roller shaft, first place its two ends on two Y-shaped brackets respectively, then rotate the handwheel A to drive the threaded rod A connected thereto to rotate, and through the setting of the pulley group, the other threaded rod A can be driven to rotate at the same time. Due to the setting of the reverse thread, the two nut seats A on the threaded rod A can be driven to approach each other, and the two U-shaped plates can be driven to approach each other, so that the two Y-shaped brackets clamp the two sides of the buffer roller shaft and achieve the purpose of fixing. When the two ends of the buffer roller shaft are placed on the two Y-shaped brackets, the length direction of the buffer roller shaft is consistent with the length direction of the sliding seat, so as to achieve the purpose of self-positioning, improve the punching accuracy, and be suitable for buffer roller shafts of different sizes and models.

[0010] Furthermore, the adjustment mechanism includes an installation groove B opened on the upper surface of the base plate, the interior of the installation groove B is rotatably connected to a threaded rod B, the outer surface of the threaded rod B is installed with a nut seat B, and the connecting block is installed on the upper surface of the nut seat B, and the side surface of the base plate is rotatably installed with a handwheel B, and the handwheel B is connected to the threaded rod B.

[0011] By rotating the hand wheel B, the threaded rod B can be driven to rotate, and the nut seat B can be driven to move along its length direction, so as to achieve the purpose of adjusting the position of the connecting block.

[0012] Furthermore, the fixing mechanism includes a positioning block inserted into the connecting block, side blocks are installed on both sides of the upper end of the positioning block, a sliding rod is inserted into the inside of the side block, and the bottom of the sliding rod is connected to the upper surface of the connecting block, a top block is installed on the top of the sliding rod, a spring is sleeved on the outer surface of the sliding rod, and the two ends of the spring are respectively abutted against the top block and the side block.

[0013] When the movable sliding seat drives the plug-in block to be inserted into the connecting block, the arc surface at the end of the plug-in block and the arc surface at the bottom of the positioning block squeeze each other, thereby driving the positioning block to move upward and drive the side block to compress the spring, so that the plug-in block can be smoothly inserted into the interior of the connecting block; when the slot moves to the bottom of the positioning block, the compressed spring releases the elastic force, which can push the positioning block to move downward and insert into the slot, thereby achieving the purpose of automatically fixing the sliding seat.

[0014] Furthermore, a pull plate is installed on the outer surface of the positioning block.

[0015] The setting of the pull plate makes it easy to drive the positioning block upward and draw it out from the slot.

[0016] Furthermore, scale lines are arranged on both sides of the upper surface of the bottom plate, and the scale lines are arranged along the length direction of the installation groove B.

[0017] By setting the scale lines, it is convenient to accurately adjust the position of the connection block.

[0018] Furthermore, mounting blocks are installed on the outer surfaces of both sides of the bottom plate, and mounting holes are provided on the mounting blocks.

[0019] By setting the mounting block, the base plate can be fixed on the drilling machine with bolts.

[0020] Furthermore, two mounting grooves A are respectively arranged on two side surfaces in the width direction of the sliding seat.

[0021] Since the two mounting grooves A are arranged on the side of the sliding seat, it is possible to prevent debris generated by punching from entering the mounting grooves A and affecting the use of the clamping mechanism, and it is convenient to clean the debris on the upper surface of the sliding seat.
