Description

Technical Field

[0001] The utility model relates to the technical field of handrail processing clamping equipment, in particular to a clamping device for processing stainless steel handrails. Background Art

[0002] When processing stainless steel handrails, they need to be clamped and fixed by a limit clamping mechanism. After that, the stainless steel handrail workpiece is subjected to operations such as grinding, punching, and polishing. Traditionally, the experimenter holds the workpiece in hand during the entire process. When positioning through the clamping mechanism, ordinary clamping devices are not convenient for lifting and lowering the workpiece and adjusting the workpiece angle, resulting in inconvenience in use and reducing the processing quality. To this end, we propose a clamping device for stainless steel handrail processing. Utility Model Content

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a clamping device for processing stainless steel handrails, comprising a mounting plate, a cylinder is mounted on the mounting plate, the piston rod of the cylinder is connected to a connecting block, the connecting block is connected to a universal connector on a box body through an axle pin, a slider is clamped in a slide groove at the bottom of the box body, the bottom of the slider is connected to a clamping plate, the top of the slider is connected to a limiting block, a bidirectional screw is threaded in a threaded hole on the side of the slider, a pull rod is hinged on the top of the box body, and the top of the pull rod is inserted into a sleeve and locked by a bolt.

[0005] In the above solution, a support column is provided at the bottom of the mounting plate.

[0006] In the above solution, a plurality of anti-slip strips are arranged in the groove of the clamping plate.

[0007] In the above solution, a guide rod is movably inserted into the guide hole on the side of the sliding block.

[0010] In the above solution, the bidirectional screw rod is movably connected to the side wall of the box body.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: the clamping device for processing stainless steel handrails has a simple and reasonable structural design and strong practicality. By arranging a cylinder as a height adjustment mechanism and arranging a connecting mechanism composed of a pull rod and a sleeve on the top of the box, the height of the box can be adjusted according to the situation, thereby meeting the height adjustment requirements of the workpiece and expanding the application scope of the device. By arranging the cooperation of structures such as slide grooves, sliders, clamping plates, limit blocks, bidirectional screw rods, guide rods and motors, the lateral distance between the two limit blocks can be adjusted, thereby the spacing between the two clamping plates can be quickly adjusted, and the workpiece is clamped and fixed from the side by the two clamping plates, effectively ensuring the stability of the workpiece during the processing process. By arranging the pull rods and sleeves used in conjunction, the length of the connecting mechanisms on both sides can be adjusted separately, and the box can be angled by using a universal connector, thereby realizing the adjustment of the inclination angle of the workpiece, facilitating the adjustment of the position angle of the workpiece, realizing multi-degree-of-freedom adjustment of the workpiece, and improving the flexibility of the device.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-2The utility model provides a technical solution: a clamping device for processing stainless steel handrails, including a mounting plate 1, a cylinder 12 is installed on the mounting plate 1, the piston rod of the cylinder 12 is connected to a connecting block 13, the connecting block 13 is connected to a universal connector 15 on a box body 16 through an axle pin 14, a slider 18 is clamped in a slide groove 17 at the bottom of the box body 16, a clamping plate 19 is connected to the bottom of the slider 18, a limiting block 2 is connected to the top of the slider 18, a bidirectional screw 23 is screwed in a threaded hole 21 on the side of the slider 18, a pull rod 26 is hinged on the top of the box body 16, and the top of the pull rod 26 is inserted into a sleeve 27 and locked by a bolt 28.

[0017] By setting the cylinder 12 as a height adjustment mechanism and setting a connecting mechanism consisting of a pull rod 26 and a sleeve 27 on the top of the box 16, the height of the box 16 can be adjusted according to the situation, thereby meeting the height adjustment requirements of the workpiece and further expanding the application range of the device.

[0018] In the above solution, a support column 11 is provided at the bottom of the mounting plate 1 .

[0019] In the above solution, a plurality of anti-skid strips 29 are arranged in the groove of the clamping plate 19. The surface of the anti-skid strips 29 is provided with anti-skid patterns, and the design of the anti-skid strips 29 further ensures the clamping stability of the clamping plate 19 on the workpiece.

[0020] In the above scheme, a guide rod 24 is movably inserted into the guide hole 22 on the side of the slider 18. Specifically, the guide rod 24 is arranged in parallel with the bidirectional screw rod 23, and the stability of the slider 18 during the lateral movement is ensured under the action of the guide rod 24.

[0021] In the above scheme, the end of the bidirectional screw 23 is connected to a motor 25. By setting the cooperation of the structures such as the slide groove 17, the slider 18, the clamping plate 19, the limit block 2, the bidirectional screw 23, the guide rod 24 and the motor 25, the lateral distance between the two limit blocks 2 can be adjusted, so that the spacing between the two clamping plates 19 can be quickly adjusted, and the workpiece is clamped and fixed from the side by the two clamping plates 19, which effectively ensures the stability of the workpiece during the processing and improves the processing effect. The motor 25 is a forward and reverse motor, and it is connected to the power supply and the switch through a wire.

[0024] Working principle:

[0025] When this clamping device for stainless steel handrail processing is used, the stainless steel handrail workpiece to be fixed is placed between two clamping plates 19, and the motor 25 is started at this time. The motor 25 drives the bidirectional screw 23 to rotate, and the bidirectional screw 23 drives the two limit blocks 2 to move along the straight line direction of the guide rod 24, so that the two clamping plates 19 are close to each other to clamp and fix the handrail workpiece. When the bolt 28 is in a non-fixed state, the height of the box 16 can be adjusted by the cylinder 12 to meet the height adjustment requirement of the workpiece. In addition, by setting the pull rod 26 and the sleeve 27 used in conjunction, the length of the connecting mechanism on both sides can be adjusted separately, and the angle of the box 16 can be adjusted in conjunction with the use of the universal connector 15, so that the inclination angle of the workpiece can be adjusted, which is convenient for adjusting the position angle of the workpiece and realizing multi-degree-of-freedom adjustment of the workpiece.
