Description

[Technical field]

[0001] The utility model belongs to the technical field of clamping devices, in particular to a long-life magnetic cover plate opening and closing clamping device. [Background technology]

[0002] A traditional automatic turntable is provided with a cover plate for positioning materials. The cover plate is rotationally connected to the base. The tail of the cover plate is driven by vertical pressure to open the cover plate to a certain angle. However, the thickness of the cover plate at the avoidance point where the cover plate is connected to the base is relatively thin, and frequent rotation and opening and closing may easily lead to breakage.

[0003] Therefore, technicians in this field have optimized the design of the cover plate. For example, the magnetic cover plate opening and closing clamping device disclosed in patent publication number CN214351876U includes a base, a base arranged on the base, a support table with a support groove arranged on the base, a rotating shaft arranged in the support groove and connected to both sides of the support table, a cover plate axially connected to the rotating shaft, a thickening layer arranged on the lower end surface of the cover plate to cover the position of the rotating shaft, a first adsorption hole arranged at the rear end of the cover plate and having an adsorption and adhesion effect with the side of the support table, and a plurality of second adsorption holes arranged at the front end of the cover plate and having an adsorption effect with the surface of the base; this solution By setting a thickened layer on the upper and lower ends of the cover plate to cover the rotating axis position, the wear of the avoidance position where the cover plate is connected to the base is delayed. Although the service life of some cover plates can be extended by delaying the wear, the problem of cover plate wear is not fundamentally solved. The pressure rod set on the base is at an acute angle to the vertical direction. When the compression cylinder drives the pressure rod to extend and the cover plate opens to 90°, the pressure of the pressure rod on the cover plate causes the cover plate to have a component force in the horizontal direction, causing the cover plate to move horizontally and hit the support table. After multiple collisions, the lower end of the cover plate covering the rotating axis position will still wear and break.

[0004] Therefore, it is necessary to provide a long-life magnetic cover opening and closing clamping device to solve the above technical problems. [Contents of the utility model]

[0005] The main purpose of the utility model is to provide a long-life magnetic cover opening and closing clamping device, which fundamentally solves the problem of wear of the lower end surface of the cover covering the rotating shaft position, increases the service life of the magnetic cover opening and closing clamping device, and can ensure the stability and accuracy of clamping positioning when opening or closing, thereby improving production efficiency.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme: a long-life magnetic cover opening and closing clamping device, which includes a jig for clamping the product, a support seat arranged at one end of the jig, a cover plate rotatably arranged on the support seat and pressing the product at one end, and an opening and closing drive mechanism arranged above the cover plate and driving the cover plate to open or close, the opening and closing drive mechanism includes a driving member, a mounting plate driven by the driving member to move up and down, and a roller assembly rotatably arranged on the mounting plate and capable of rolling vertically on the upper surface of one end of the cover plate.

[0008] Furthermore, the roller assembly includes a connecting bracket which is arranged on the mounting plate and is in a vertical state, and the lower end of the connecting bracket is rotatably connected to the roller via a second rotating shaft.

[0011] Furthermore, the support seat is provided with a first limiting surface for limiting the pressed state of the cover plate and a second limiting surface for limiting the opened state of the cover plate.

[0012] Furthermore, a first magnet is disposed on the cover plate, and a third magnet cooperating with the first magnet is disposed on the first limiting surface, and the first magnet and the third magnet have opposite polarities.

[0013] Furthermore, a second magnet is arranged on the cover plate, and a fourth magnet cooperating with the second magnet is arranged on the second limiting surface, and the second magnet has the same polarity as the fourth magnet.

[0030] Please refer to Figure 1-Figure 9 The present embodiment is a high-life magnetic cover opening and closing clamping device, which includes a fixture 1 for clamping the side of a product 200, a support seat 2 arranged at one end of the fixture 1, a cover 3 rotatably arranged on the support seat 2 and pressing the product at one end, and an opening and closing driving mechanism 4 arranged on the cover 3 and driving the cover 3 to open or close. The opening and closing driving mechanism 4 includes a driving member 41, a mounting plate 42 fixed at the output end of the driving member 41 and driven by the driving member 41 to move up and down, and a roller assembly 43 rotatably arranged at the end of the mounting plate 42 and capable of vertically rolling on the upper surface of one end of the cover 3.

[0031] One end of the cover plate 3 is a driving end 31 driven to rotate by the roller assembly 43, and the other end is a clamping end 32 for clamping the product on the fixture 1. The surface of the clamping end 32 is protrudingly provided with a first clamping block 33 for clamping the product 200 and a branch plate 34 for clamping the product 200, and the surface of the branch plate 34 is protrudingly provided with a plurality of second clamping blocks 35 for clamping the product 200.

[0032] The fixture 1 is provided with a limit block 11 for guiding and limiting the clamping end 31 when it is closed, a receiving block 12 for receiving the clamping end 32 is provided in front of the limit block 11, and a positioning hole 36 for correspondingly engaging and positioning with the limit block 11 is provided on the cover plate 3. When the cover plate 3 is closed and corresponds to the fixture 1, the limit block 11 of the fixture 1 is correspondingly engaged and positioned with the positioning hole 311 of the cover plate 3, and the upper end of the cover plate 3 falls on the receiving block 12, and the first clamping block 33 and the second clamping block 35 of the cover plate 3 are both pressed on the surface of the product 200.

[0033] The upper surface of the support seat 2 is provided with a first limiting surface 21 for limiting the lower position of the cover plate 3 when it is closed, and the side surface is provided with a second limiting surface 22 for limiting the driving end 31 of the cover plate 3.

[0034] The cover plate 3 is provided with a first adsorption hole 37 on the side facing the product, and a second adsorption hole 38 is provided at the lower end of the first adsorption hole 37 facing the second limiting surface 22 . A first magnet is provided in the first adsorption hole 37 , and a second magnet is provided in the second adsorption hole 38 .

[0035] A third adsorption hole 23 is provided on the first limiting surface 21 , a fourth adsorption hole 24 is provided on the second limiting surface 22 , a third magnet is provided in the third adsorption hole 23 , and a fourth magnet is provided in the fourth adsorption hole 24 .

[0036] The polarity of the first magnet is opposite to that of the third magnet, and the polarity of the second magnet is the same as that of the fourth magnet. When the drive cover 3 corresponds to the closed fixture 1, the first adsorption hole 37 corresponds to the third adsorption hole 23, and the first magnet and the third magnet attract each other due to different polarities, so that the cover 3 and the fixture 1 are closed and pressed against the product. When the drive cover 3 is opened, the second adsorption hole 38 corresponds to the fourth adsorption hole 24, and the second magnet and the fourth magnet repel each other with the same polarity to prevent the cover 3 from hitting the second limiting surface 22 of the support seat 2. Therefore, when the cover 3 is opened, the driving end 31 of the cover 3 covering the first rotating shaft position will not wear out, and the cover 3 is not easy to wear, and has a higher service life.

[0037] The roller assembly 43 includes a connecting bracket 431 fixed on the mounting plate 42 in a vertical state, and the lower end of the connecting bracket 431 is rotatably connected to the roller 432 through the second rotating shaft. When the opening and closing mechanism 4 is driven into place, the roller 432 can press against the lower end of the connection between the cover plate 3 and the first rotating shaft of the support seat 2. When the driving member 41 drives the mounting plate 42 to move up and down, the roller 432 can roll vertically on the surface of the cover plate 3 to open or close the cover plate 3; when the cover plate 3 is opened to 90 degrees in this way, the roller 432 will contact the cover plate 3, but the roller 432 has no horizontal force on the cover plate 3, and the second magnet and the fourth magnet have the same polarity and repel each other to prevent the cover plate 3 from hitting the second limiting surface 22 of the support seat 2. Therefore, the driving end 31 of the cover plate 3 will not move horizontally to hit the support seat 2, so that the cover plate 3 remains in a vertical state. Therefore, when the cover plate 3 is opened, the lower end of the cover plate 3 covering the position of the first rotating shaft will still not be worn, and the cover plate 3 is not easy to wear, and has a higher service life.

[0038] In this embodiment, when there are multiple jigs 1 for clamping the product 200, multiple roller assemblies 43 can be correspondingly arranged on the opening and closing drive mechanism 4, so that multiple cover plates 3 can be opened or closed at the same time, thereby improving production efficiency.

[0039] When the present embodiment is applied, when the fixture 1 clamps the side of the product 200, the driving member 41 drives the mounting plate 42 to move upward so that the roller 432 presses against the surface of the cover plate 3. The driving member 41 continues to drive the mounting plate 42 to move upward, and the roller 432 pressed against the surface of the cover plate 3 begins to roll vertically toward the upper end of the cover plate 3, and the cover plate 3 shows a tendency to close. Due to the gravity of the cover plate 3 itself and the attraction of the first magnet in the first adsorption hole 37 and the third magnet in the third adsorption hole 23 with different polarities, the cover plate 3 and the fixture 1 are automatically closed, and the cover plate 3 is clamped from above. After tightening the product 200, relevant tests are carried out; when the test is completed, the driving member 41 drives the mounting plate 42 to move downward so that the roller 432 is pressed against the surface of the cover 3, and the driving member 41 drives the mounting plate 42 to continue to move downward. The roller 432 pressed on the surface of the cover 3 begins to roll toward the lower end of the cover 3, and the cover 3 shows a tendency to open. After the roller 432 moves vertically downward into place, the cover 3 automatically opens, and the second magnet and the fourth magnet repel each other with the same polarity to prevent the cover 3 from hitting the second limiting surface 22 of the support seat 2, thereby keeping the cover 3 in a vertical state.

[0040] The present invention provides a long-life magnetic cover opening and closing clamping device, (1) through the opening and closing driving mechanism 4 set on the surface of the cover 3, the opening and closing driving mechanism 4 includes a driving member 41, a mounting plate 42 fixed to the output end of the driving member 41 and driven by the driving member 41 to move up and down, and a roller assembly 43 rotatably set at the end of the mounting plate 42 and able to roll in the vertical direction on the surface of the cover 3, the roller 432 of the roller assembly 43 is pressed against the lower end of the connection between the cover 3 and the first rotating shaft of the support seat 21, when the driving member 41 drives the mounting plate 42 to move up and down, the roller 432 can roll vertically on the surface of the cover 3 to open or close the cover 3. Compared with the prior art, the scheme provided by the present invention makes the cover 3 When the opening approaches 90°, the roller 432 has no horizontal force on the cover 3, and the second magnet and the fourth magnet have the same polarity and repel each other, thereby preventing the cover 3 from hitting the second limiting surface 22 of the support seat 2 and keeping the cover 3 in a vertical state. Therefore, the driving end 31 of the cover 3 will not move horizontally to hit the support seat 2, thereby keeping the cover in a vertical state. Therefore, when the cover 3 is opened, the driving end 31 of the cover 3 will not cause wear of the cover 3 when it is at the position covering the first rotating axis, and the cover 3 has a longer service life. (2) When there are multiple fixtures 1 for clamping the product 200, multiple roller assemblies 43 can be correspondingly arranged on the opening and closing drive mechanism 4, so that multiple cover plates 3 can be opened or closed at the same time, thereby improving production efficiency. Therefore, compared with the prior art, the magnetic cover opening and closing clamping device 100 provided in the present solution fundamentally solves the problem of wear of the lower end surface of the cover 3 covering the first rotating axis position, thereby improving the service life of the magnetic cover opening and closing clamping device, and can ensure the stability and accuracy of clamping positioning when opening or closing, thereby improving production efficiency.

[0041] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
