Description

Technical Field

[0001] This utility model relates to the field of clamping tooling technology, specifically to a clamping device for parts processing. Background Technology

[0002] During parts machining, if the parts are not stably fixed to the machining platform or machine tool, vibration and displacement will occur, leading to a decrease in machining accuracy. Clamping ensures the stability of the parts, preventing this from happening and ensuring machining accuracy. Furthermore, if the workpiece is not stably fixed to the machining platform or machine tool during parts machining, displacement or deformation may occur, potentially even leading to accidents. Clamping with clamping equipment can prevent these situations and ensure the safety of parts machining.

[0003] Most existing clamping devices on the market are divided into two types. One type can adjust and fix the angle of the parts after clamping them to facilitate machining or drilling. However, this type of clamping device is not convenient for rotary turning of the parts. The other type can drive the parts to rotate after clamping them to facilitate rotary turning, but it is difficult to fix the machined surface of the parts at a fixed angle. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a clamping device for processing parts, which can simultaneously fix the parts at a fixed angle and drive the parts to rotate by switching modes.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

After the clamping motor is started, the control gear rotates, and each slider moves along the groove towards the central top plate.

[0013] As an improvement, the locking switching structure includes a transmission rod, a limiting disc, and a sliding sleeve; one end of the transmission rod is connected to the corresponding rotating shaft of the drum, and the other end is connected to and fixed to the limiting disc, and a spline is provided on the side wall; the sliding sleeve is sleeved on the transmission rod and slides back and forth on the transmission rod.

[0016] The advantages of this utility model compared with the prior art are as follows:

[0017] 1. This utility model uses a screw and turbine to control and lock the rotating drum, which can fix the clamped parts after rotating and adjusting them to a certain angle, making it easier to process their surfaces and making it more convenient to use.

A spline is provided on the side wall of the transmission rod 14. The sliding sleeve 16 is sleeved on the transmission rod 14 and slides back and forth along the transmission rod 14. It is worth noting that magnetic adsorption blocks are embedded in the rear end face and the front end of the inner wall of the sliding sleeve 16, respectively. Magnetic adsorption blocks are also embedded in the outer wall of the transmission rod 14 and the front side wall of the limiting plate 15, respectively, and the corresponding two magnetic adsorption blocks attract each other.

[0035] In the specific implementation of this embodiment:

[0036] The workpiece to be processed is clamped and fixed between the fixed base 3 and the movable base 4 (different clamping methods are used depending on the processing requirements and size of the workpiece; specifically, when the workpiece is a long rod or plate, both ends of the workpiece are clamped and fixed to the clamping structures on both sides, and abut against the top plates 7 on both sides; when the workpiece is a small block or short rod, only the workpiece is fixed to the clamping structure of the fixed base 3; the following explanation uses a long rod-shaped workpiece as an example). One end of the workpiece is placed against the center of the top plate 7 of the clamping structure on the fixed base 3, and controlled by the control module... Group 23 controls the corresponding clamping motor 8 to start, and the corresponding control gear 9 rotates to drive each rack 12, and each slider 10 moves linearly along the slider 10 toward the center of the top plate 7 until each chuck 13 clamps and fixes one end of the part at the center of the top plate 7. Then the moving seat 4 slides toward the fixed seat 3, and its top plate 7 abuts against the other end of the part. Through the control module 23, another clamping motor 8 is started, and another control gear 9 rotates to drive each rack 12, and each slider 10 moves linearly along the slider 10 toward the center of the top plate 7 until each chuck 13 clamps and fixes the other end of the part.

Then, the turbine 17 engages with the screw 18, and the new model enters the adjustment and locking mode. Manually rotate the top handle 19, and the screw 18 starts to rotate, driving the turbine 17 and the sliding sleeve 16 to rotate. This causes the rotating drum 5 to rotate slowly and drive the parts to rotate at a certain angle. Then stop rotating the handle 19. At this time, the parts and the rotating drum 5 are locked at this angle with the cooperation of the screw and turbine, so that processing can be performed.

[0038] The sliding sleeve 16 is manually slid so that it abuts against the limiting plate 15 and is attracted to the limiting plate 15 by the magnetic adsorption block. Then the driving gear 22 and the driven gear 21 mesh, and the new model enters the rotation drive mode. The control module 23 controls the rotary motor 20 to start, and under the transmission of gears and splines, the transmission rod 14 drives the rotating drum 5 and the parts to rotate, thereby processing the parts.
