Technical Field

[0001] The utility model relates to the technical field of clamping mechanisms, in particular to an up and down positioning and clamping mechanism. Background Art

[0002] The upper and lower positioning and clamping mechanisms are usually used in various application fields that require precise positioning and clamping of components. The main purpose of this mechanism is to ensure that the workpiece or component is positioned and clamped at a specific position to achieve precise processing, assembly, testing or fixation, such as in mechanical processing, medical equipment, electronic manufacturing and other industrial fields.

[0003] When the existing upper and lower positioning and clamping mechanisms are used on a workbench, in order to improve the stability during positioning and use, they are usually fixed by bolts. However, since different batches of products require clamping and positioning, after completing two batches of products of different models, it is necessary to promptly replace the clamping mechanism corresponding to the next batch for use. It is necessary to remove multiple bolts again to complete the disassembly and replacement, which is time-consuming and the process is too cumbersome. Utility Model Content

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] Reference Figure 1-3 The utility model provides an embodiment: an up and down positioning and clamping mechanism, including a mounting plate 1, a quick-release assembly is provided on the rear side of the mounting plate 1, a clamping assembly is provided on the front side of the mounting plate 1, the quick-release assembly includes an L-shaped plate 3, the L-shaped plate 3 is fixedly connected to the rear side of the mounting plate 1, a workbench body 4 is slidably connected to the rear side of the mounting plate 1, a clamping groove 5 is provided on the front side of the workbench body 4, a moving groove 6 is provided on the inner wall of the workbench body 4, a plurality of clamping columns 7 are fixedly connected to the left and right sides of the inner wall of the workbench body 4, a pressure rod 8 is slidably connected to the middle side of the top of the workbench body 4, steel wires 9 are provided on the left and right sides of the outer wall of the pressure rod 8, locking columns 10 are slidably connected to the left and right sides of the inner wall of the workbench body 4, and a spring 11 is provided on the top of the locking column 10.

[0039] By pressing the pressure rod 8, the steel wires 9 on both sides are driven to pull the locking columns 10 on both sides upward under the limit of the positioning column 7. The disengagement movement between the locking column 10 and the L-shaped plate 3 enables the quick disassembly function of the overall clamping mechanism. When replacing the clamping mechanism, the L-shaped plate 3 can be inserted into the workbench body 4 through the clamping groove 5, and then after entering the appropriate position inside, the pressure rod 8 is sent down, and under the stress of multiple springs 11, the locking column 10 drives the steel wire 9 to move down and completes the connection with the L-shaped plate 3. Such a design can effectively improve the disassembly and assembly speed of the clamping mechanism while ensuring stability, and the hole grooves of multiple L-shaped plates 3 can be unified in advance. In this way, when fixing multiple different clamping mechanisms, they can be fixed through the connection of the locking column 10. Such a design can effectively reduce the use cost and make the mold shape consistent.

[0040] Reference Figure 1-3 The L-shaped plate 3 is slidably connected to the inner wall of the clamping groove 5, and the locking column 10 is slidably connected to the left and right sides of the top of the L-shaped plate 3. The spring 11 is arranged on the left and right sides of the inner wall of the workbench body 4. The steel wire 9 is arranged on the outer wall of the two clamping columns 7.

[0041] After the L-shaped plate 3 slides into the workbench body 4, the steel wire 9 acts as a traction transmission to transmit the upward force on the locking column 10 generated by the downward pressure of the pressure rod 8, so that the locking column 10 can be fixed by the spring 11 after the L-shaped plate 3 enters.

[0042] Reference Figure 3 The pressure rod 8 is slidably connected to the inner wall of the movable groove 6.

[0043] The position of the pressing rod 8 can be limited by the design of the movable groove 6 .

[0044] Reference Figure 1-2 The clamping assembly includes a bottom supporting block 12, and multiple bottom supporting blocks 12 are fixedly connected to the front bottom of the mounting plate 1. The four corners of the top of the bottom supporting block 12 are fixedly connected with stabilizing columns 15. The left and right ends of the front side of the mounting plate 1 are fixedly connected with limiting blocks 2. The inside of the limiting block 2 is slidably connected with a connecting plate 13. The outer wall of the stabilizing column 15 is slidably connected with a positioning plate 14. A protective groove 17 is opened on the top of the bottom supporting block 12, and the left and right sides of the bottom of the positioning plate 14 are fixedly connected with electric telescopic rods 16.

[0045] The product is placed into the protective groove 17 through the groove on the top of the positioning plate 14, and then the upper and lower positioning and pressing degrees of the product are adjusted by synchronously opening the electric telescopic rod 16. During the lowering process of the positioning plate 14, the connection between the connecting plate 13 and the limit block 2 can be used to improve the movement stability of the positioning plate 14. Through such a design, the downward pressure angles of multiple positions of the positioning plate 14 can be balanced to avoid tilting during the downward pressure process and other situations that affect positioning.

[0046] Reference Figure 1-2 The top of the positioning plate 14 is provided with a through slot corresponding to the protection slot 17. The bottom supporting block 12 is fixedly connected to the output end of the electric telescopic rod 16, and the positioning plate 14 is fixedly connected to the front side of the connecting plate 13.

[0047] The groove is designed so that after the conical product is placed in the space in front of the bottom support block, the product can be gradually pressed down for compaction and positioning. In the process of compaction and positioning, the stabilizing column 15 and the limiting block 2 are designed to improve the balance during the pressing process and avoid tilting to one side.

[0048] Working principle: when the staff completes the processing and positioning of a batch of products and needs to replace the clamping mechanism according to the next batch of products, the staff presses the pressure rod 8 to drive the steel wires 9 on both sides to pull the locking columns 10 on both sides up under the limit of the positioning column 7, and the disengagement movement between the locking column 10 and the L-shaped plate 3 enables the quick disassembly function of the overall clamping mechanism. When replacing the clamping mechanism, the L-shaped plate 3 can be inserted into the workbench body 4 through the clamping groove 5, and then after entering the appropriate position inside, the pressure rod 8 is loosened, and under the stress of multiple springs 11, the locking column 10 drives the steel wire 9 to move down and complete the connection with the L-shaped plate 3. Such a design can effectively improve the disassembly and assembly speed of the clamping mechanism while ensuring stability, and the hole grooves of multiple L-shaped plates 3 can be unified in advance, so that when fixing multiple different clamping mechanisms, they can be fixed through the connection of the locking column 10. Such a design can effectively reduce the use cost and make the mold shape consistent.

[0049] When the clamping mechanism is in use, the staff can place the product into the protective groove 17 through the groove on the top of the positioning plate 14, and then adjust the upper and lower positioning and clamping degree of the product by synchronously opening the electric telescopic rod 16. During the lowering process of the positioning plate 14, the connection between the connecting plate 13 and the limit block 2 can be used to improve the movement stability of the positioning plate 14. Through such a design, the downward pressure angles of multiple positions of the positioning plate 14 can be balanced to avoid tilting during the downward pressure process and other situations that affect positioning.
