Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a clamp with a steering effect. Background Art

[0002] The fixture is one of the commonly used equipment in general mechanical processing. It is used to fix the parts during the mechanical processing of the parts, making the processing work accurate and successful, and avoiding the problem of processing into defective products.

[0003] In the process of implementing the solution, the inventors found that the following problems in the prior art have not been well solved: although the traditional clamps can clamp the parts, in some multi-angle full-row processing, the position of the drill bit needs to be changed, and the change of the position of the drill bit requires the connected drive motor and drive components to be changed together. This operation method is relatively cumbersome. At the same time, in many cases, an electrically controlled mobile device is used to change the position of the drill bit, so as to achieve the effect of convenient position change, but the early equipment adjustment and the later running program debugging are relatively troublesome and the cost is relatively high. Utility Model Content

[0004] The main purpose of the utility model is to provide a clamp with a steering effect, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A clamp with a steering effect comprises an inner ring tube and a clamping tooth, the number of the inner ring tubes is two, the outer wall of the inner ring tube is fixed with an annular slide rail, the outer wall of the annular slide rail is provided with a plurality of external teeth, the internal connection of the annular slide rail is slidably connected with a slider, the interior of the inner ring tube is provided with an annular plate, two brackets are provided at both ends between the annular plates, the two ends of one side of the bracket are respectively fixed to the annular plate, the two ends of the other side of the bracket are respectively fixed to the slider at matching positions, a side plate is fixed between the two adjacent brackets, a screw is fixed on the side of the side plates away from each other, a pressure plate is provided at the position of the screw, and a rod hole is drilled on the pressure plate at the position of the screw, an adjusting nut is threadedly connected on the outer wall of the screw away from the side plate, a plurality of adjusting screws are oppositely arranged on the annular plate, and the annular plates are threadedly connected with the adjusting screws respectively.

[0007] Preferably, the pressing plates are respectively sleeved on the outer wall of the screw through the rod holes, and the pressing plates are located between the side plates and the adjusting nut, and the inner diameter of the rod holes matches the outer diameter of the screw.

[0008] Preferably, the latch teeth are respectively meshed and connected with external teeth that match in height.

[0009] Preferably, the pressure plate is fixed with keys at the top and bottom of the inner wall of the rod hole, the top and bottom of the screw rod are chiseled with corresponding key slots, and the keys are respectively inserted into the key slots and slidably connected thereto.

[0010] Preferably, the adjusting nut contacts the side wall adjacent to the pressing plate.

[0011] Preferably, flange feet are fixed to the four top corners of the upper inner ring tube.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] By placing the parts between two annular plates, the rotation of several adjusting screws can form a clamping and fixing effect on the top and bottom of the parts. For some special-shaped parts, the clamping can be adapted according to the adjusting screws in different positions and the number of turns of the adjusting screws, so as to achieve a multi-directional, multi-angle and multi-shaped clamping effect, making the processing more stable.

[0014] The annular plate is fixed by a bracket and a slider slidably connected in the annular slide rail. The sliding of the slider in the annular slide rail can drive the annular plate to rotate, thereby achieving a steering effect, so that the drill bit can directly process the turned parts without changing its position, avoiding the high cost caused by the traditional relocation of the driving equipment, the cumbersome position caused by the equipment debugging, and the system operation debugging;

[0015] After the position adjustment is completed, the rotation of the adjusting nut can drive the pressure plate to move toward the position of the annular slide rail. When the pressure plate is about to approach the annular slide rail, the locking teeth on its side wall will engage with the external teeth on the outer walls of the two annular slide rails. After the engagement, the slider cannot rotate and change direction, thereby enabling the parts clamped by the adjusting screw to be stable during the processing process.

[0023] Specifically, the pressing plates 9 are sleeved on the outer wall of the screw rod 7 through the rod holes 10 , and the pressing plates 9 are located between the side plates 6 and the adjusting nut 8 . The inner diameter of the rod hole 10 matches the outer diameter of the screw rod 7 .

[0024] Specifically, the latch teeth 11 are respectively meshed and connected with the external teeth 4 of matching height, and the pressure plate 9 is located at the top and bottom of the inner wall of the rod hole 10, and the keys 12 are fixed thereon. The top and bottom of the screw rod 7 are respectively provided with corresponding key slots, and the keys 12 are respectively inserted into the inside of the key slots and slidably connected thereto, so that the movement of the pressure plate 9 is horizontal, and the adjusting nut 8 is in contact with the side wall close to the pressure plate 9, so that the latch teeth 11 on the pressure plate 9 can stably mesh with the external teeth 4 to maintain the limit of the steering rear angle.

[0025] Specifically, flange feet 15 are fixed to the four corners of the top of the upper inner ring tube 1 to facilitate fixed support of the device.

[0026] Working principle:

[0027] By placing the parts between the two annular plates 13, the rotation of several adjusting screws 14 can form a clamping and fixing effect on the top and bottom of the parts. For some special-shaped parts, the adjusting screws 14 at different positions and the number of rotations of the adjusting screws 14 can be used for adaptive clamping, so as to achieve a multi-directional, multi-angle and multi-shaped clamping effect, making the processing more stable.

[0028] The annular plate 13 is fixed to the slider 3 slidably connected to the annular slide rail 2 through the bracket 5. The sliding of the slider 3 in the annular slide rail 2 can drive the annular plate 13 to rotate, thereby achieving a steering effect, so that the drill bit can directly process the turned parts without changing its position, avoiding the high cost caused by the traditional relocation of the driving device, the cumbersome position caused by the equipment debugging, and the system operation debugging;

[0029] After the position adjustment is completed, the rotation of the adjusting nut 8 can drive the pressure plate 9 to move toward the position of the annular slide rail 2. When the pressure plate 9 is about to approach the annular slide rail 2, the latch teeth 11 on its side wall will engage with the external teeth 4 on the outer walls of the two annular slide rails 2. After the engagement, the slider 3 cannot rotate and change direction, thereby enabling the parts clamped by the adjusting screw 14 to obtain stability during the processing process.
