Technical Field

[0001] This utility model relates to a clamping device for a tooling fixture, belonging to the field of machining technology. Background Technology

[0002] When grinding a workpiece, the workpiece needs to be fixed in a fixture. For workpieces requiring high machining precision, the clamping stability of the fixture is crucial to ensure the dimensional accuracy of the ground surface. Existing fixture clamping devices are not sufficiently stable in their clamping state during grinding, resulting in the ground surface dimensions and accuracy failing to meet process requirements, particularly in the parallelism and perpendicularity of the ground surfaces. Summary of the Invention

[0003] The purpose of this invention is to provide a clamping device for a tooling fixture. This clamping device ensures the stability of the workpiece during the grinding process, thereby guaranteeing the machining accuracy of the ground surface.

[0004] The technical solution of this utility model is as follows: a clamping device for a tooling fixture, including a fixture base with a U-shaped structure, a material release block is provided in the U-shaped cavity of the fixture base, a material stop block is provided on the left side of the surface of the material release block, a material push block is provided on the right side, the right end of the material push block is connected to a push rod through the stop block, the push rod passes through the through hole at the right end of the fixture base, and multiple round-head clamping devices are provided on the left end face of the material push block.

[0005] In the aforementioned clamping device for a tooling fixture, the round-head clamping device is a round-head clamping screw.

[0006] In the aforementioned clamping device for a tooling fixture, the stop block and the release block are fixed to the fixture base by screws.

[0007] In the aforementioned clamping device for a tooling fixture, a ball head is provided at the left end of the push rod. The ball head is inserted into the spherical groove on the right end face of the top material block. The two half blocks are fixed to the right end face of the top material block by screws. The push rod body passes through the through hole formed when the two half blocks are joined together.

[0008] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model adopts the above-mentioned technical solution, in which two round-headed clamping devices are evenly connected to the left end of the top material block. Under the action of external power, the top rod drives the top material block and the round-headed clamping devices to clamp to the left onto the workpiece being ground. The two round-headed clamping devices can make the clamping force evenly distributed, ensuring the stability of the workpiece being ground during the grinding process, thereby ensuring the machining accuracy of the ground surface. This device has a simple structure, is easy to use, and has good application value. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0014] An embodiment of this utility model: A clamping device for a tooling fixture includes a fixture base 1 with a U-shaped structure. A material release block 8 is provided in the U-shaped cavity of the fixture base 1. A material stop block 2 is provided on the left side of the surface of the material release block 8, and a material push block 5 is provided on the right side. The right end of the material push block 5 is connected to a push rod 7 via a stop block 6. The push rod 7 passes through a through hole at the right end of the fixture base 1. A plurality of round-head clamping devices 4 are provided on the left end face of the material push block 5.

[0015] The round-head tightening device 4 is a round-head tightening screw, which is screwed into the threaded hole provided on the left end face of the top material block 5, thereby facilitating the quick installation, replacement and disassembly of the round-head tightening device 4.

[0016] The stop block 2 and the release block 8 are fixed to the fixture base 1 with screws, thereby enabling quick installation, replacement and disassembly of parts. When different sizes of workpieces 3 need to be processed, different release blocks 8 and stop blocks 2 need to be replaced to ensure that the round head clamping device 4 is pressed against the center position of the side of the workpiece 3 as much as possible, thus ensuring the stability of the workpiece during the grinding process.

[0017] The left end of the top rod 7 is provided with a ball head, which is inserted into the spherical groove on the right end face of the top material block 5. The two half blocks 6 are fixed to the right end face of the top material block 5 by screws. The two half blocks 6 are two identical structures arranged symmetrically. Each block has a semi-circular notch. The two semi-circular notches are combined to form a through hole. The rod body behind the ball head of the top rod 7 can pass through the through hole, thereby locking and fixing the top rod 7 through the block 6.

[0018] A clamping device for a tooling fixture includes a fixture base 1, a stop block 2, a round-headed clamping screw 4, a top block 5, a stop block 6, a top rod 7, a discharge block 8, and a workpiece 3 to be ground.

[0019] The clamping device of this utility model fixes the push rod 7 to the right end of the push block 5 by screws and stop 6, and fixes the push block 5 to the left end by two round-headed clamping screws. The push rod 7 passes through the through hole at the right end of the fixture base 1. The push block 5 is placed on the surface of the release block 8. The release block 8 is connected to the fixture base 1 by two screws. The stop block 2 is connected to the fixture base 1 by two screws. The right end of the push rod 7 is connected to the power device.

[0020] Two round-headed screws are evenly connected to the left end of the top material block 5. Under the action of external power, the top material block 5 and the tightening round-headed screws are driven to the left by the top rod 7 to tighten onto the workpiece 3 to be ground. The two round-headed tightening screws can make the tightening force evenly distributed, ensuring the stability of the workpiece 3 to be ground during the grinding process, thereby ensuring the machining accuracy of the grinding surface.
