Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, in particular to a clamping mechanism for tooling. Background Art

[0002] The clamping mechanism is used on the machine tool fixture, and the position of the clamping mechanism on the machine tool fixture is fixed. When the part is placed on the machine tool fixture and the clamping button is pressed, the auxiliary clamping mechanism is converted from the open state to the clamping state. The traditional welding fixture clamping mechanism adopts a manual or pneumatic four-link hinge clamping method. The clamping force is mainly used to maintain the relative position of the workpiece assembly, overcome the elastic deformation of the workpiece and other external forces, so that it can be combined with the positioning support surface to ensure assembly accuracy.

[0003] Due to the limitation of tooling size, in order to achieve clamping of objects of different specifications, complex mechanisms are required for clamping. Multiple clamping is required to complete the clamping and positioning of the entire workpiece. Therefore, the positioning auxiliary operation time of multiple movements of the mechanism is increased, and the complex mechanism increases labor costs, resulting in increased manufacturing costs. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a clamping mechanism for tooling, which overcomes the deficiencies of the prior art and effectively solves the problems in the prior art that the positioning auxiliary operation time due to multiple movements of the mechanism is increased, and the complex mechanism causes increased labor costs, leading to increased manufacturing costs.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A clamping mechanism for tooling comprises a mounting plate, a first base being fixed at one end of the top of the mounting plate, and a cylinder being arranged on one side of the first base, a clamping assembly being arranged on one side of the cylinder, and the clamping assembly being rotatably connected to a second base mounted on the other end of the top of the mounting plate, a supporting plate being arranged below the second base, and a screw rod being rotatably connected to one corner of the top of the supporting plate, and a sliding rod being fixed to the other corner of the top of the supporting plate, the clamping assembly comprising a connecting block, a fixing plate fixed to both sides of the outer wall of one end of the connecting block, and a pressing block fixed to the top of the connecting block.

[0007] Place the object on the top of the support plate. The cylinder rotates with the second base and the clamping assembly through two connecting blocks, and rotates with the fixed plate and the connecting head. When the cylinder extends, it pushes the clamping assembly to rotate toward the support plate, clamping the object between the pressure block and the support plate. When the cylinder contracts, it pulls the clamping assembly to rotate away from the support plate to release the clamping of the object.

[0008] Preferably, connecting heads are fixed at both ends of the cylinder, and the two connecting heads are rotatably connected to the first base and the clamping assembly respectively.

[0009] The cylinder is connected by rotation of the connecting head, so that the cylinder can adjust the angle between the first base and the clamping assembly during the extension and retraction process.

[0010] Preferably, a screw hole is provided at one corner of the top of the mounting plate, and a sliding hole is provided at another corner of the top of the mounting plate.

[0011] The screw rod and the slide rod are connected respectively through the screw holes and the slide holes opened on the mounting plate.

[0012] Preferably, the screw rod and the screw hole form a threaded fit, and the top end of the screw rod is connected to a rotating wheel handle.

[0013] Turn the wheel handle to rotate the screw rod, and the rotating screw rod drives the bottom support plate to move.

[0014] Preferably, the slide rod and the slide hole form a sliding fit, and the height of the slide rod is the same as the height of the screw rod.

[0015] The slide bar slides in the slide hole, so that the auxiliary support plate moves.

[0016] Preferably, the two fixing plates are rotatably connected to the connecting head, and the connecting block is rotatably connected to the second base, and an anti-sliding block is connected to one end of the top of the pressing block.

[0017] Through the rotational cooperation between the connecting block and the second base, and the rotational cooperation between the fixing plate and the connecting head, when the cylinder extends, the clamping assembly is pushed to rotate toward the support plate, clamping and fixing the object between the pressing block and the support plate; when the cylinder contracts, the clamping assembly is pulled to rotate away from the support plate, releasing the clamping of the object.

[0018] The beneficial effects of the utility model are:

[0019] By placing the object on the top of the support plate, the cylinder rotates with the second base and the clamping assembly through two connecting blocks, and rotates with the fixed plate and the connecting head. When the cylinder extends, the clamping assembly is pushed to rotate toward the support plate, and the object is clamped and fixed between the pressure block and the support plate. When the cylinder contracts, the clamping assembly is pulled to rotate away from the support plate to release the clamping of the object. This effectively solves the problem in the prior art that the positioning auxiliary operation time due to multiple movements of the mechanism is increased, and the complex mechanism causes increased labor costs, resulting in increased manufacturing costs.

[0027] Connectors 3 are fixed at both ends of the cylinder 4, and the two connectors 3 are rotatably connected to the first base 2 and the clamping assembly 5 respectively. The cylinder 4 is rotatably connected to the first base 2 and the clamping assembly 5 through the rotation of the connector 3, so that the cylinder 4 can adjust the angle between the first base 2 and the clamping assembly 5 during the extension and retraction process. A screw hole is provided at one corner of the top of the mounting plate 1, and a sliding hole is provided at the other corner of the top of the mounting plate 1.

[0028] The screw rod 8 forms a threaded match with the screw hole, and the top of the screw rod 8 is connected with a rotating wheel handle 9. The rotating wheel handle 9 rotates the screw rod 8, and the rotating screw rod 8 drives the support plate 7 at the bottom to move. The sliding rod 10 forms a sliding match with the sliding hole. The height of the sliding rod 10 is the same as that of the screw rod 8. The sliding rod 10 slides in the sliding hole to assist the support plate 7 to move.
