Description

Technical Field

[0001] This utility model relates to the field of positioning and clamping fixture technology, specifically a positioning and clamping fixture for cylinder laser heat treatment. Background Technology

[0002] When performing laser heat treatment on the cylinder, a positioning and clamping fixture is used to position and clamp the cylinder to facilitate laser heat treatment.

[0003] Existing positioning and clamping fixtures for laser heat treatment of cylinder blocks cannot provide pre-positioning when fixing steel cylinder blocks, resulting in long adjustment time and low clamping and positioning efficiency. Secondly, when the cylinder block is placed on the fixture table, the contact area between the fixture table and the cylinder block is large, and heat is conducted to the fixture during heat treatment, which can easily cause thermal deformation of the fixture. Therefore, there is an urgent need for a positioning and clamping fixture for laser heat treatment of cylinder blocks to solve the above technical problems. Utility Model Content

The existing positioning and clamping fixtures for laser heat treatment of cylinders cannot provide pre-positioning when fixing steel cylinders, resulting in long adjustment time and low clamping and positioning efficiency. Secondly, when the cylinder is placed on the fixture table, the contact area between the fixture table and the cylinder is large, and heat is conducted to the fixture during heat treatment, which can easily lead to thermal deformation of the fixture.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A positioning and clamping fixture for laser heat treatment of cylinder blocks includes a fixture table, a base connected to the bottom of the fixture table, support blocks connected to the upper left and upper right ends of the fixture table, connecting blocks connected to one side of each of the two support blocks, electric push rods installed on one side of each of the two connecting blocks, one end of each of the two electric push rods passing through the connecting block and the support block in sequence and connected to a positioning clamping block, a honeycomb-shaped heat dissipation vent in the middle of the fixture table, magnetic auxiliary positioning plates embedded on both sides of the top of the fixture table, and a synchronization controller installed on the right end of the fixture table.

[0007] As a preferred technical solution of this utility model, the two magnetic auxiliary positioning plates are arranged symmetrically about the tooling table along the left and right axes.

[0008] As a preferred embodiment of this utility model, the magnetic auxiliary positioning plate is in the shape of a cuboid structure.

[0009] As a preferred embodiment of this utility model, the two support blocks are arranged symmetrically about the tooling table.

[0010] As a preferred embodiment of this utility model, the two positioning clamps are arranged symmetrically about the tooling table.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention provides pre-positioning when fixing a steel cylinder by setting a magnetic auxiliary positioning plate, reducing adjustment time and improving clamping and positioning efficiency. The honeycomb heat dissipation vents on the tooling table reduce the contact area with the cylinder, improve heat dissipation efficiency, and reduce the risk of tooling thermal deformation.
