Description

Technical Field

[0001] The utility model relates to the technical field of clamping fixtures, and more specifically, to an inclined wedge type clamping fixture containing a tension spring. Background Art

[0002] The workpiece is clamped and fixed by a clamping fixture, and after the workpiece is clamped and fixed, it is processed by a processing device. In the prior art, the workpiece is placed, and then a device such as a cylinder is used to drive a clamping structure to clamp the workpiece. However, this causes a distance between the clamping structure and the workpiece, which may cause the workpiece to slide after being placed due to this distance, resulting in a change in the position of the workpiece on the fixture, thus making it inconvenient to clamp the workpiece, and after the clamping is completed, it is impossible to quickly separate from the workpiece to release the clamping of the workpiece. Summary of the Utility Model

[0003] In order to overcome the deficiencies of the prior art, the utility model provides an inclined wedge type clamping fixture containing a tension spring, which has the advantage of avoiding shaking before clamping.

[0004] To achieve the above object, the utility model provides the following technical solution: an inclined wedge type clamping fixture containing a tension spring, including a processing table, and further including:

[0005] A lifting cylinder, the lifting cylinder is fixedly connected to the bottom end of the processing table, the output shaft of the lifting cylinder is threadedly connected with a lifting block, the top end of the processing table is fixedly connected with a fixing plate, a tension spring is fixedly connected to the right side of the fixing plate, the right side of the tension spring is fixedly connected with a moving rod, and the moving rod has flexibility in moving left and right;

[0006] A moving side block, the moving side block is threadedly connected to the top end of the moving rod, an inclined wedge surface is provided on the right side of the moving rod, the inclined wedge surface is attached to the left side of the moving rod, the top end of the processing table is fixedly connected with a fixing rod, a bolt is threadedly connected to the inner cavity of the fixing rod, and a fixing side block is threadedly connected to the side of the fixing rod away from the outside of the processing table through the bolt, and the fixing side block is rectangular;

[0007] The beneficial effects of adopting the above technical solution are as follows: By placing the workpiece on the top of the placement plate, at this time, the three sides of the workpiece are clamped by the fixed edge blocks, so as to position and guide the workpiece, making some relatively slippery workpieces only slide in the direction of the moving edge block. At this time, the lifting cylinder is started to drive the lifting block to descend, so that the inclined wedge surface on the right side of the lifting block contacts the left side of the moving rod, and the moving rod is pushed to move, and the moving edge block is pushed towards the placement plate, thereby clamping and fixing the workpiece. After the workpiece processing is completed, the lifting cylinder is started to drive the lifting block to rise, so that the inclined wedge surface rises. At this time, after the moving rod loses the limit of the inclined wedge surface, the moving rod is quickly pulled towards the fixed plate by the tension of the tension spring, thus realizing the positioning of the workpiece before placement, making it only slide in the direction of the moving edge block, and then through the setting of the tension spring, it can quickly reset and release the limit after the processing is completed.

[0008] As a further improvement of the present utility model, a rolling wheel is movably connected to the inner cavity of the inclined wedge surface, and an anti-slip strip is fixedly connected to the right side of the moving edge block;

[0009] The beneficial effects of adopting the above technical solution are as follows: Through the rolling wheel in the inner cavity of the inclined wedge surface, when the lifting block drives the inclined wedge surface to descend and contact the left side of the moving rod, the friction between the inclined wedge surface and the moving rod can be reduced through the rolling wheel, making the inclined wedge surface move more smoothly when descending and pushing the moving rod to move. Then, through the anti-slip strip on the right side of the moving edge block, the friction between the moving edge block and the workpiece is increased, avoiding the situation of workpiece deviation when clamping the workpiece.

[0010] As a further improvement of the present utility model, the output shaft of the lifting cylinder is threadedly connected with a first mounting bolt, and the output shaft of the lifting cylinder is threadedly connected with the lifting block through the first mounting bolt;

[0011] The beneficial effects of adopting the above technical solution are as follows: Through the setting of the first mounting bolt, the lifting block is detachable, so that after the lifting block is damaged during long-term use, it is convenient to replace, improving the convenience during maintenance and replacement.

[0012] As a further improvement of the present utility model, a second mounting bolt is threadedly connected to the inner cavity of the moving rod, and the moving rod is threadedly connected with the moving edge block through the second mounting bolt;

[0013] The beneficial effects of adopting the above technical solution are as follows: Through the setting of the second mounting bolt, the moving rod can be threadedly connected with the moving edge block through the second mounting bolt, and then the moving edge block is detachable, so that the moving edge block can be replaced with different models according to the needs of the manufacturer, so as to clamp different workpieces.

[0014] As a further improvement of the present utility model, a placement plate is fixedly connected to the top end of the processing table. There are multiple fixing edge blocks, and the placement plate is located between the multiple fixing edge blocks;

[0015] The beneficial effect of adopting the above technical solution is that since the placement plate is located between the multiple fixing edge blocks, after the workpiece is placed on the top end of the placement plate, the three sides of the workpiece can be directly limited and clamped by the fixing edge blocks, thereby preventing the workpiece from shifting in other directions.

[0016] As a further improvement of the present utility model, support feet are fixedly connected to the bottom end of the processing table, and the output shaft of the lifting cylinder passes through the processing table and is threadedly connected to the lifting block;

[0017] The beneficial effect of adopting the above technical solution is that the processing table is supported by the support feet at the bottom end of the processing table, so that the processing table can stably fix the lifting cylinder and support the workpiece at the top end of the processing table, enabling the processing equipment to perform processing operations on the workpiece.

[0018] As a further improvement of the present utility model, a plurality of guiding blocks are fixedly installed on the top end of the processing table, and the moving rod is located between the plurality of guiding blocks;

[0019] The beneficial effect of adopting the above technical solution is that through the arrangement of the guiding blocks, the guiding blocks can position and guide the moving rod, so that when the lifting block or the tension spring drives the moving rod to move, the moving rod can only move along the guiding blocks and will not shift in other directions, improving the stability during use.

[0020] As a further improvement of the present utility model, the rolling wheel is in contact with the left side of the moving rod, and the rolling wheel has the freedom to rotate;

[0021] The beneficial effect of adopting the above technical solution is that when the rolling wheel is in contact with the left side of the moving rod, the rolling wheel can roll, thereby reducing the friction force with the moving rod. Description of the Drawings
