The screw rod and the pedestal of the utility model are at a certain angle, so the screw rod has a downward pressure while supporting the product, ensuring that the bottom of the groove of the product is tightly fitted, and at the same time, tightening the screw further fixes the product, ensuring that the product will not move under the action of external force.

Description

A glueless coupling fixture

technical field

The utility model relates to a clamp, in particular to a simple and reliable glue-free coupling clamp. the

Background technique

The existing coupling fixture X-axis, Y-axis and the product are non-fitting locking, the X-axis and Y-axis are prone to change in position under the contact of external force, and the Z-axis is generally cantilever type. As a result, there is a defect in the overall rigidity of the fixture; the penetration force generated during the existing laser welding is relatively large, and it is very easy to cause the X-axis and the Y-axis to move slightly, thereby affecting the change of the product parameters after welding, resulting in the scrapping of the product. the

In addition, the cost of the existing fixture is too high, the number of parts is relatively large, the structure is very complicated, and the operation is also relatively complicated, which cannot meet the needs of the existing mechanical industry field. the

Utility model content

Aiming at the deficiencies of the prior art, the utility model provides a non-adhesive coupling fixture with simple and reasonable structure, few parts, good overall rigidity of the fixture, good fixing effect and favorable price. the

Realize the above-mentioned purpose The technical scheme that the utility model adopts is:

A glue-free coupling fixture, which is composed of a fixture seat, a screw head, a screw rod, a tightening screw and a handle. The fixture seat is composed of a base, a base and four centrally symmetrical fixed bosses connected in sequence. The screw rod One end is connected with the screw head, and the other end is connected with the fixed boss; one end of the fastening screw is connected with the handle, and the other end is connected with the base. the

The base is provided with a groove for accommodating the product and a threaded through hole, and the tightening screw passes through the threaded through hole to the groove to realize the fixing and positioning of the product. the

The fixed boss is provided with an inclined fixed thread through hole, and the screw rod passes through the fixed thread through hole to be connected with the fixed boss. the

The range of inclination angle of the fixed threaded through hole is 0°-90°. the

The surface of the screw head is provided with knurled straight lines. the

The head of the tightening screw is provided with knurled straight lines. the

There is a certain angle relationship between the screw rod and the base of the utility model, so the screw rod also has a downward pressure when it withstands the product, ensuring that the bottom of the groove of the product fits closely. Further fixation is carried out to ensure that the product will not move under the action of external force. the

In addition, the utility model has a simple and reasonable structure, a small number of parts, good overall rigidity of the fixture and a favorable price, and generally meets the double-sided requirements for both functionality and affordability of the fixture in the development process of mechanical manufacturing. the

Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described. the

Detailed ways

Referring to Figures 1 to 2, the utility model provides a glueless coupling fixture, which is composed of a fixture seat, a screw head 4, a screw rod 5, a tightening screw 6 and a handle 7, and the fixture seat is composed of a base 1, a The base 2 is composed of four centrally symmetrical fixed bosses 3, one end of the screw 5 is connected with the screw head 4, and the other end is connected with the fixed boss 3; one end of the tightening screw 6 is connected with the handle 7, The other end is connected with the base 2. the

The base 2 is provided with a groove 8 for accommodating the product and a threaded through hole 9, and the tightening screw 6 passes through the threaded through hole 9 to the groove 8 to realize the fixing and positioning of the product. the

The fixing boss 3 is provided with an inclined fixing threaded through hole 10, and the screw rod 5 passes through the fixing threaded hole and is connected with the fixing boss. the

The inclination angle of the fixed threaded through hole 10 ranges from 0° to 90°. the

The surface of the screw head 4 is provided with knurled straight lines. the

The head of the fastening screw 6 is provided with knurled straight lines. the

There is a certain angle relationship between the screw rod 5 and the base 2 of the utility model, so the screw rod 5 also has a downward pressure while resisting the product, so as to ensure that the bottom of the groove 8 of the product closely fits, and at the same time, tighten the The screw 6 also further fixes the product to ensure that the product will not move under the action of external force. the

In addition, the utility model has a simple and reasonable structure, a small number of parts, good overall rigidity of the fixture and a favorable price, and generally meets the double-sided requirements for both functionality and affordability of the fixture in the development process of mechanical manufacturing. the

The utility model is not limited to the above-mentioned embodiments, and the use of the same or similar structure as the above-mentioned embodiments of the utility model is within the protection scope of the utility model. the
