Description

Technical Field

[0001] The utility model relates to the technical field of part surface positioning, and particularly relates to a device for facilitating part surface positioning. Background Technique

[0002] During the production process, it is often necessary to batch process the upper surfaces of plate-like parts, such as printing, dispensing, laser engraving, etc. Before completing these operations, it is required that the heights of the surfaces to be processed are consistent. However, due to errors in the thickness of the plates, if the plates are directly placed on the bottom plate of the equipment, the surfaces to be processed will be different between different plates, often resulting in reduced processing accuracy. Sometimes, it even collides with the print head or dispensing nozzle, causing damage to the materials and the equipment. Therefore, a positioning device is needed to position the part surfaces.

[0003] Traditional positioning devices usually adopt a seesaw structure. When the fixture positions parts with different thicknesses, it will cause the spring to twist, thereby reducing the service life of the spring. At the same time, one end of the seesaw contacts the part, resulting in poor stability of part positioning. For this reason, a device for facilitating part surface positioning is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a device for facilitating part surface positioning, so as to solve the problems in the above background technique that traditional positioning devices usually adopt a seesaw structure. When the fixture positions parts with different thicknesses, it will cause the spring to twist, thereby reducing the service life of the spring. At the same time, one end of the seesaw contacts the part, resulting in poor stability of part positioning.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A device for facilitating part surface positioning, including a base. One end of the top of the base is fixedly connected with a fixed block. One end of the top of the fixed block is provided with a positioning block. A deep groove is opened at the top of the fixed block. A guide post is installed inside the deep groove. An installation groove is arranged at the bottom of the guide post. A telescopic spring is arranged inside the installation groove. A through groove is opened at one end of the fixed block. A fixing plate is movably penetrated through the inside of the through groove. A fixture is installed at one end of the fixing plate. Two rotating shafts are movably penetrated through one side of the fixed block. Connecting plates are fixedly connected to both ends of the rotating shafts. Connecting shafts are fixedly connected to both the upper and lower sides of the fixing plate on one side of the fixture. One end of the connecting plate is movably connected to the outside of the connecting shaft.

[0006] Preferably, a step surface is arranged on the outside of the guide post. The fixing plate is movably sleeved on the outside of the guide post. The bottom of the guide post abuts against the step surface.

[0007] Preferably, one end of the telescopic spring abuts against the bottom of the base.

[0008] Preferably, a pressing handle is installed at the other end of the fixing plate, and the pressing handle is located outside the fixing block.

[0009] Preferably, a notch is provided at one end of the base, and the fixture is located above the notch.

[0010] Preferably, a plate part is installed between the fixture and the positioning block.

[0011] Compared with the prior art, the present utility model adopts the above technical solutions and has the following technical effects:

[0012] By moving the pressing handle downward, the pressing handle drives the fixing plate to move downward inside the through groove. At this time, the fixing plate drives the guiding column to move inside the deep groove, so that the guiding column compresses the telescopic spring. One end of the fixing plate drives the fixture to move downward. During the downward movement of the fixture, the fixture drives the two connecting shafts to move downward, so that the connecting plate rotates around the rotating shaft. The two connecting plates form a parallelogram structure, which can ensure that the top side of the fixture is always parallel to the bottom side of the positioning block. When positioning plate parts with different thicknesses, the contact area between the fixture and the plate part remains unchanged, improving the stability of plate part positioning.

[0013] Compared with the traditional positioning method of the toggle structure, the fixture will not deflect during movement, avoiding the twisting of the telescopic spring, thereby prolonging the service life of the telescopic spring. BRIEF DESCRIPTION OF THE DRAWINGS

Compared with the traditional positioning method of the toggle structure, the fixture 10 will not deflect during the movement, avoiding the torsion of the telescopic spring 6, thereby increasing the service life of the telescopic spring 6;

[0024] On one side of the fixed block 2, two rotating shafts 11 penetrate through it movably. Both ends of the rotating shaft 11 are fixedly connected with connecting plates 12. On the upper and lower sides of the fixing plate 9 on one side of the fixture 10, connecting shafts 13 are fixedly connected. One end of the connecting plate 12 is movably connected to the outside of the connecting shaft 13; by moving the fixing plate 9 downward inside the through groove 8, at this time, the fixing plate 9 drives the guiding column 5 to move inside the deep groove 4, so that the guiding column 5 compresses the telescopic spring 6. One end of the fixing plate 9 drives the fixture 10 to move downward. During the downward movement of the fixture 10, the fixture 10 drives the two connecting shafts 13 to move downward, so that the connecting plate 12 rotates around the rotating shaft 11. The two connecting plates 12 form a parallelogram structure, which can ensure that the top side of the fixture 10 is always parallel to the bottom side of the positioning block 3. When positioning plate parts 16 with different thicknesses, the contact area between the fixture 10 and the plate part 16 remains unchanged, improving the positioning stability of the plate part 16.

[0025] A stepped surface 7 is arranged on the outside of the guiding column 5. The fixing plate 9 is movably sleeved on the outside of the guiding column 5. The bottom of the guiding column 5 abuts against the stepped surface 7. After the plate part 16 is placed, by loosening the pressing handle 15, the telescopic spring 6 will drive the guiding column 5 to move upward, so that the stepped surface 7 of the guiding column 5 pushes the fixing plate 9 to move upward, so that the fixture 10 drives the plate part 16 to move upward, and the plate part 16 abuts against the bottom side of the positioning block 3, thus realizing that the upper surface heights of plate parts 16 with different thicknesses are the same and completing the surface positioning of the plate part 16; the other end of the fixing plate 9 is provided with a pressing handle 15. The pressing handle 15 is located outside the fixed block 2. By pressing the pressing handle 15 downward to move, the pressing handle 15 drives the fixing plate 9 to move downward inside the through groove 8; a plate part 16 is installed between the fixture 10 and the positioning block 3. A notch 14 is opened at one end of the base 1. The fixture 10 is located above the notch 14. The notch 14 can ensure the normal movement of the fixture 10.

[0026] Working principle or structural principle: When it is necessary to clamp and fix the plate part 16, by pressing down the pressing handle 15 to move downward, the pressing handle 15 drives the fixing plate 9 to move downward inside the through groove 8. At this time, the fixing plate 9 drives the guide post 5 to move inside the deep groove 4, so that the guide post 5 compresses the telescopic spring 6. One end of the fixing plate 9 drives the fixture 10 to move downward. At this time, the plate part 16 can be placed between the fixture 10 and the positioning block 3. During the downward movement of the fixture 10, the fixture 10 drives the two connecting shafts 13 to move downward, so that the connecting plate 12 rotates around the rotating shaft 11. The two connecting plates 12 form a parallelogram structure, which can ensure that the top side of the fixture 10 is always parallel to the bottom side of the positioning block 3, improve the positioning stability of the plate part 16, and the fixture 10 will not deflect, avoiding the torsion of the telescopic spring 6, thereby improving the service life of the telescopic spring 6; when the placement of the plate part 16 is completed, by releasing the pressing handle 15, the telescopic spring 6 will drive the guide post 5 to move upward, so that the step surface 7 of the guide post 5 pushes the fixing plate 9 to move upward, so that the fixture 10 drives the plate part 16 to move upward, and the plate part 16 abuts against the bottom side of the positioning block 3, so as to make the upper surface heights of the plate parts 16 with different thicknesses the same, and complete the surface positioning of the plate part 16.
