DETAILED DESCRIPTION
[0015] To facilitate understanding of the present invention, a more comprehensive description of the present invention is provided below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided solely to provide a more thorough and comprehensive understanding of the disclosure of the present invention.
[0016] See attached Figure 1-5 As shown, in this embodiment, a multi-specification workpiece clamping device includes a frame 1, a fixed clamping plate 2 fixedly mounted on the frame 1, a movable clamping plate 3 movably mounted on the frame 1, and a driving unit 6 fixed to the frame 1 and used to drive the movable clamping plate 3 to perform directional translation relative to the fixed clamping plate 2. Specifically, the fixed clamping plate 2 is fixedly mounted on the frame 1 in a vertical position by a plurality of preset bolts, so that one side end surface of the fixed clamping plate 2 serves as a clamping surface.
[0017] In this embodiment, the movable clamping plate 3 is provided with a fixed pressure rod 4 and a dynamic pressure rod 5 which are parallel to each other and extend toward the fixed clamping plate 2, wherein the movable clamping plate 3 is movably arranged on the frame 1 in a vertical shape, and the movable clamping plate 3 is provided with a fixing hole for the fixed pressure rod 4 to be fixed and fitted (that is: the tail end of the fixed pressure rod 4 serves as the fixed end and is locked and fixed in the fixing hole by means of a preset bolt, and the front end of the fixed pressure rod 4 serves as the clamping end); the movable clamping plate 3 is formed with a transversely extending adjustment slide hole 31, and the dynamic pressure rod 5 can be loosely and tightly moved through the adjustment slide hole 31 and can be moved laterally along the adjustment slide hole 31 (that is: the tail end of the dynamic pressure rod 5 serves as the fixed end and is detachably locked and fixed in the adjustment slide hole 31 by means of a preset bolt, and the front end of the dynamic pressure rod 5 serves as the clamping end). Therefore, based on the size specifications of the workpiece 100 to be measured, the lateral position of the dynamic pressure rod 5 in the adjusting slide hole 31 can be manually adjusted in advance, thereby increasing or decreasing the lateral gap between the fixed pressure rod 4 and the dynamic pressure rod 5. After adjusting to the required position, the dynamic pressure rod 5 can be locked and fixed, so that the specifications can be easily switched. It is easy to operate and has strong adaptability.
[0018] In this embodiment, in order to improve the stability of the directional translation of the movable clamping plate 3, a positioning plate 7 fixed on the frame 1 and between the movable clamping plate 3 and the fixed clamping plate 2 is also included, wherein the positioning plate 7 is formed with a first through-hole 71 and a second through-hole 72 for the fixed pressure rod 4 and the dynamic pressure rod 5 to pass through respectively, and the second through-hole 72 is consistent with the adjustment slide hole 31 and is arranged to extend in the transverse direction. At this time, the first through-hole 71 and the second through-hole 72 play a guiding role for the fixed pressure rod 4 and the dynamic pressure rod 5, ensuring the stability of the fixed pressure rod 4 and the dynamic pressure rod 5 during movement. Secondly, since the position of the positioning plate 7 is fixed, it also plays a role in limiting the directional translation stroke of the movable clamping plate 3, that is: when the movable clamping plate 3 is relatively directional translated close to the fixed clamping plate 2 to reach the maximum stroke, the movable clamping plate 3 just contacts the positioning plate 7 to limit the movable clamping plate 3 from continuing to translate toward the fixed clamping plate 2.
[0019] Furthermore, the movable splint 3 is fixed with at least one guide rod 8 extending toward the fixed splint 2. Preferably, a guide rod 8 is provided at both ends of the movable splint 3; the positioning plate 7 is provided with at least one guide hole 73 for the guide rod 8 to movably pass through in a one-to-one correspondence. Preferably, guide holes 73 are provided at both ends of the positioning plate 7 for two guide rods 8 to pass through in a one-to-one correspondence. Therefore, during the directional translation of the movable splint 3, the sliding guiding effect between the guide hole 73 and the guide rod 8 is used to improve the stability of the translation of the movable splint 3.
[0020] In this embodiment, the driving unit 6 is a telescopic cylinder with a telescopic rod, wherein the telescopic cylinder is fixed on the frame 1 and its telescopic rod is connected to the back of the movable clamping plate 3. Thus, the telescopic action of the telescopic cylinder drives the movable clamping plate 3 to perform directional translation through the telescopic rod.
[0021] In summary, in order to facilitate understanding of the above-mentioned clamping detection device, the following is an explanation in combination with a specific working method.
[0022] Before use, loosen the dynamic pressure rod 5 and adjust the position along the adjustment slide hole 31 according to the model and specifications of the workpiece 100 to be measured. After adjusting to the rated position, lock the dynamic pressure rod 5. When in use, the drive unit 6 is reset to make the dynamic clamping plate 3 cooperate with the fixed pressure rod 4 and the dynamic pressure rod 5 away from the fixed clamping plate 2, so that a space is formed between the fixed clamping plate 2, the fixed pressure rod 4 and the dynamic pressure rod 5 to accommodate the workpiece 100 to be measured. Then the operator puts the workpiece 100 to be measured in, and then the drive unit 6 drives the dynamic clamping plate 3 to cooperate with the fixed pressure rod 4 and the dynamic pressure rod 5 to gradually approach the fixed clamping plate 2, so that the clamping ends of the fixed pressure rod 4 and the dynamic pressure rod 5 cooperate with the clamping surface of the fixed clamping plate 2 to clamp the workpiece 100 to be measured, until the dynamic clamping plate 3 and the positioning plate 7 are limited and in conflict with each other, thus completing the clamping operation, so as to facilitate subsequent inspection work.
[0023] Furthermore, the columnar rod structure of the fixed pressure rod 4 and the dynamic pressure rod 5 is mainly used to adapt to the following Figure 1 The structure of the workpiece 100 to be measured is shown. The skilled person in the art can adjust the structures of the fixed pressure rod 4 and the dynamic pressure rod 5 according to the actual structural features of the workpiece 100 to be measured, and no specific limitation is made here.
[0024] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any person skilled in the art who, without departing from the scope of the present invention, utilizes the above-disclosed technical content to make further possible variations, modifications, or alterations to the present invention's technical solution shall constitute equivalent embodiments of the present invention. Therefore, any equivalent and equivalent variations made in accordance with the principles of the present invention, without departing from the scope of the present invention's technical solution, shall be encompassed within the scope of protection of the present invention.
