Description

Technical Field

[0001] The utility model relates to the technical field of jewelry processing equipment, in particular to a tablet press for precise jewelry processing. Background Art

[0002] During the jewelry processing, metal blocks need to be pressed into thin sheets to facilitate processing. Usually, a sheet press is used for pressing. In order to control the pressing thickness, the sheet press is often equipped with hydraulic telescopic rods, electric push rods and other tools for controlling the lifting.

[0003] However, such thickness adjustment by means of hydraulic telescopic rods, electric push rods and other tools that control the lifting and lowering of the sheet all have the problem of difficulty in accurately adjusting the thickness. In actual operation, the operator is required to repeatedly adjust the thickness up and down and compare it with the measuring tool to adjust the thickness of the final tablet, which brings great inconvenience to the operator. Utility Model Content

[0004] The purpose of the utility model is to provide a tablet press for precise processing of jewelry to solve the above-mentioned deficiencies in the prior art.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A tablet press for precision processing of jewelry, comprising a workbench, a mounting frame is provided on the workbench, and a fine adjustment mechanism is also provided on the mounting frame; the fine adjustment mechanism comprises a driving gear fixedly arranged on a fixed rod on the mounting frame, the fixed rod is rotatably arranged on the mounting frame, two transmission gears are respectively meshed and connected to the driving gear, each of the transmission gears is fixedly connected to a screw rod, each of the screw rods is rotatably connected to the workbench and the mounting frame, and each of the screw rods is also threadedly connected to a connecting block; a pressure roller is rotatably connected between the two connecting blocks, the roller shaft of the pressure roller passes through a connecting block on one side and is fixedly connected to an output shaft of a motor, and the motor is fixedly connected to a placement plate on the connecting block; it also comprises a power mechanism, the power mechanism comprises a handle fixedly connected to an end of the fixed rod, and a locking assembly is also provided on the workbench; the locking assembly comprises a fixed block fixedly connected to the workbench, a locking rod is slidably connected in the fixed block, a spring is fixedly connected between the locking rod and the fixed block, and a locking gear ring meshed with the driving gear is fixedly connected to the locking rod.

[0007] Furthermore, the connecting block is slidably connected to a limiting frame on the workbench.

[0008] Furthermore, the limiting frame is provided with scale lines.

[0009] Furthermore, an indicator plate is fixedly provided on the connecting block, the bottom surface of the indicator plate and the lowest point of the pressure roller are in the same plane, and the indicator plate points to the scale line.

[0010] In the above technical solution, the utility model provides a tablet press for precise jewelry processing with the following beneficial effects:

[0011] Through the fine adjustment mechanism, the driving gear is rotated to drive the transmission gear to rotate, and the rotation of the gear drives the two screws to rotate in the same direction. Since the connecting block is constrained by the pressure roller and the connecting block on the opposite side and cannot rotate, the connecting block moves along the axial direction of the screw, and the movement of the connecting block drives the pressure roller to move up and down, thereby accurately adjusting the position of the pressure roller. By driving the screw to drive the pressure roller to move up and down, the operator can adjust the thickness of the layer more accurately without repeated debugging, which greatly facilitates the operator's work.

[0012] It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure.

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0022] In one embodiment provided by the present utility model, please refer to Figure 1-4 A tablet press for precision processing of jewelry, comprising a workbench 1, a mounting frame 11 is provided on the workbench 1, and a fine adjustment mechanism is also provided on the mounting frame 11; the fine adjustment mechanism comprises a driving gear 2 fixedly arranged on a fixed rod 12 on the mounting frame 11, the fixed rod 12 is rotatably arranged on the mounting frame 11, and two transmission gears 21 are respectively meshed and connected to the driving gear 2, each of the transmission gears 21 is fixedly connected to a screw rod 22, each of the screw rods 22 is rotatably connected to the workbench 1 and the mounting frame 11, and each of the screw rods 22 is also threadedly connected to a connecting block 3; a pressure roller 6 is rotatably connected between the two connecting blocks 3, and the roller shaft of the pressure roller 6 passes through the connecting block 3 on one side and is fixedly connected to the output shaft of the motor, and the motor is fixedly connected to the placement plate on the connecting block 3.

[0023] Through the fine adjustment mechanism, the driving gear 2 is rotated to drive the transmission gear 21 to rotate, and the rotation of the gear drives the two screws 22 to rotate in the same direction. Since the connecting block 3 is constrained by the pressing roller 6 and the connecting block 3 on the opposite side and cannot rotate, the connecting block 3 moves along the axial direction of the screw 22, and the movement of the connecting block 3 drives the pressing roller 6 to move up and down, thereby accurately adjusting the position of the pressing roller 6. By driving the screw 22 to drive the pressing roller 6 to move up and down, the operator can adjust the thickness of the layer more accurately without repeated debugging, which greatly facilitates the operator's work.

[0024] It also includes a power mechanism, which includes a handle 13 fixedly connected to the end of a fixed rod 12, and a locking assembly is also provided on the workbench 1. The locking assembly includes a fixed block 4 fixedly connected to the workbench 1, a locking rod 41 is slidably connected inside the fixed block 4, a spring is fixedly connected between the locking rod 41 and the fixed block 4, and a locking gear ring 42 meshing with the driving gear 2 is fixedly connected to the locking rod 41. In order to save device space and optimize the structural layout, the gear ring is an incomplete gear ring.

[0025] The locking rod 41 is moved away from the driving gear 2 to disengage the locking gear ring 42 from the driving gear 2, and the handle 13 is turned to drive the driving gear 2 to rotate. The rotation of the driving gear 2 can control the lifting and lowering of the pressing roller 6. When the thickness is adjusted to a specified value, the locking gear ring 42 on the locking rod 41 is meshed with the driving gear 2 under the action of the spring, and the gear ring is fully meshed with the driving gear 2 under the support of the spring to lock the driving gear 2, thereby fixing the height of the pressing roller 6. Precise adjustment by manual means is more convenient for operators, especially older people, and after becoming familiar with the device, the thickness of the layer can be quickly adjusted.

[0026] Furthermore, the connection block 3 is slidably connected to the limit frame 5 on the workbench 1. The limit frame 5 further limits the rotation of the connection block 3, improves the stability of the connection block 3 when moving up and down, reduces the lateral wear of the roller shaft of the pressure roller 6 and the connection block 3, and prolongs the practical life of the device.

[0027] Furthermore, the limit frame 5 is provided with a scale line 51 . The connecting block 3 is also fixedly provided with an indicator plate 31 , the bottom surface of the indicator plate 31 and the lowest point of the pressure roller 6 are in the same plane, and the indicator plate 31 points to the scale line 51 .

[0028] When adjusting the thickness of the pressure strip, the overlap between the bottom surface of the indicator plate 31 and the scale line 51 can be observed. The overlap is the thickness of the pressed sheet by the pressing roller 6. This setting allows the operator to directly determine the thickness of the pressed sheet without taking other measuring tools.

[0029] Working principle:

[0030] When adjusting the thickness, manually move the locking rod 41 away from the driving gear 2 so that the locking gear ring 42 is disengaged from the driving gear 2, and turn the handle 13 to drive the driving gear 2 to rotate. The rotation of the driving gear 2 drives the transmission gear 21 to rotate, and the rotation of the rotating gear drives the two screws 22 to rotate in the same direction. Since the connecting block 3 is constrained by the pressure roller 6 and the connecting block 3 and the limit frame 5 on the opposite side and cannot rotate, the connecting block 3 moves along the axial direction of the screw 22. The movement of the connecting block 3 drives the pressure roller 6 to move up and down. The operator can accurately adjust the position of the pressure roller 6 by observing the overlapping scale of the bottom surface of the indicator plate 31 and the scale line 51. After the adjustment is completed, release the locking rod 41. Under the action of the spring, the locking gear ring 42 on the locking rod 41 engages with the driving gear 2 to lock the position of the driving gear 2 and the pressure roller 6.

[0031] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
