Description

Technical Field

[0001] The utility model relates to the technical field of tin bar grinding, in particular to a high-efficiency grinding device for tin bar production. Background Art

[0002] Tin bar is a product of solder. Before the tin bar is made into a finished product, because the edges and corners at both ends are sharp when it is taken out from the mold, or because of the fine workmanship of the mold, slag is attached to the surface of the tin bar. Therefore, some grinding devices are often used to grind its edges and slag to facilitate subsequent processing.

[0003] At present, there are two main methods for grinding the two ends of the tin bar. One is that the staff uses a handheld grinder to grind the two ends of the tin bar separately, but this method is difficult to ensure grinding accuracy, and the labor is large and the efficiency is low.

[0004] The second method is to fix the tin bar on the fixture, and then use two grinders to grind the two ends of the tin bar respectively. For example, the authorization announcement number CN214264984U discloses an edge grinding device for lead-free tin bar production, which drives the two-way screw 2 to rotate through the output shaft of the motor 2, so that the two linkage plates are close to each other, and the two motors 3 are also close to each other, until the two grinding plates are in contact with the tin bar, and then the two ends of the tin bar can be polished. However, by setting up two grinding components, the device can still only grind one tin bar at a time, and the grinding efficiency is low.

[0005] In view of this, we propose an efficient grinding device for tin bar production. Utility Model Content

DETAILED DESCRIPTION

[0029] 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.

[0030] See also Figure 1-Figure 6 , a technical solution provided by the utility model:

[0031] A high-efficiency grinding device for tin bar production includes a base 1, on which an inner grinding piece 2 and an outer grinding piece 3 are arranged, the inner grinding piece 2 and the outer grinding piece 3 are respectively used to grind the two ends of the tin bar, and the base 1 is provided with a clamp assembly 5 and a driving assembly 4 for driving the clamp assembly 5 to rotate.

[0032] In this embodiment, the top of the base 1 is a circular plate, the inner polishing piece 2 is annular, and is fixedly mounted at the center of the top of the base 1. The outer polishing piece 3 is fixedly mounted on the top of the base 1, and is arc-shaped, embracing the inner polishing piece 2. A polishing portion is provided on the outer wall of the inner polishing piece 2 and the inner wall of the outer polishing piece 3, and the two polishing portions are respectively used to polish the two ends of the tin bar.

[0033] The outer polishing piece 3 is provided with an opening for loading and unloading. One end of the opening is provided with a chamfer to facilitate the tin bar to enter between the inner polishing piece 2 and the outer polishing piece 3.

[0034] Combination Figure 2 and Figure 3 As shown, point A is the center of the arc where the outer polishing part 3 is located, and point B is the center of the circle where the inner polishing part 2 is located. The two centers do not coincide, so that the outer polishing part 3 and the inner polishing part 2 are in an eccentric state. When the tin bar rotates clockwise with point B as the center, the end of the tin bar will be naturally polished as the rotation angle changes.

[0035] As an embodiment, the fixture assembly 5 includes a rotating shaft 51, which is rotatably connected to the inner wall of the base 1. The rotating shaft 51 is located inside the inner polishing member 2 and is concentrically arranged with the inner polishing member 2 to drive the solder bar to rotate with point B as the center.

[0036] Furthermore, the rotating shaft 51 is fixedly connected with a plurality of connecting plates 52. In this embodiment, four connecting plates 52 are used as an example. The four connecting plates 52 are distributed in a circular array with point B as the center. The ends of the four connecting plates 52 away from the rotating shaft 51 are fixedly connected with a first frame 53. The bottom of the first frame 53 is fixedly connected with a second frame 54. A placement space is formed between the first frame 53 and the second frame 54 for placing tin bars. Four tin bars can be placed at a time through the four placement spaces distributed in a circular array. When the rotating shaft 51 rotates, the four tin bars can be driven to be polished at the same time, thereby improving the polishing efficiency.

[0037] On this basis, the angle of the opening on the outer polishing piece 3 is not less than ninety degrees, so that the two second frames 54 are exposed outside the outer polishing piece 3, and then a loading area is formed in the lower left corner and a unloading area is formed in the lower right corner, which facilitates orderly and efficient loading and unloading.

[0038] Furthermore, a plurality of movable rods 55 are slidably connected to both side walls of the second frame body 54, one end of the movable rod 55 is fixedly connected to a connecting rod 56, and a guide wheel 57 is rotatably connected to the surface of the connecting rod 56. Figure 6As shown, there are multiple guide wheels 57, which are divided into two groups. The two groups of guide wheels 57 are symmetrically distributed around the axis of the second frame 54. The guide wheels 57 are in contact with the tin bar, which can reduce the friction force on the tin bar when it moves in the second frame 54, and prevent the two sides of the tin bar from being worn. The other end of the movable rod 55 passes through the second frame 54 and is fixedly connected to a baffle 58, which is elastically connected to the second frame 54 through a spring 59. The spring 59 is sleeved on the outside of the movable rod 55 to provide elastic force to support the baffle 58, so that the two groups of guide wheels 57 can clamp the tin bar through the elastic force.

[0039] Combination Figure 4 As shown, the driving assembly 4 includes a reduction gear 44 and a residual gear 43. The reduction gear 44 is fixedly connected to the rotating shaft 51. The residual gear 43 can mesh with the reduction gear 44 after rotating a certain angle, thereby driving the reduction gear 44 to rotate ninety degrees. When the residual gear 43 is not meshed with the reduction gear 44, the reduction gear 44 stops rotating, which facilitates loading and unloading of the tin bars.

[0040] In addition, the driving assembly 4 also includes a support frame 41, which is fixedly mounted on the base 1. A driving motor 42 is fixedly mounted on the support frame 41, and an output end of the driving motor 42 is connected to the residual gear 43 for driving the residual gear 43 to rotate.

[0041] When using the high-efficiency grinding device for tin bar production of the utility model, firstly, the grinded tin bar is placed between the first frame 53 and the second frame 54 from the notch of the arc-shaped outer grinding piece 3, and the tin bar is pushed inward so that one end of the tin bar contacts the inner grinding piece 2.

[0042] Then, the driving motor 42 is started, and the output end of the driving motor 42 drives the residual gear 43 to rotate. The residual gear 43 meshes with the reduction gear 44 once every rotation, and drives the reduction gear 44 to rotate ninety degrees through the meshing. When the reduction gear 44 rotates, it simultaneously drives the four connecting plates 52 to rotate through the rotating shaft 51. The four connecting plates 52 respectively drive the first frame body 53 and the second frame body 54 fixed thereon to rotate. The second frame body 54 drives the workpiece to rotate clockwise with point B as the center of the circle through two sets of guide wheels 57. During the rotation, the burrs at both ends of the tin bar will be polished by the outer polishing piece 3 and the inner polishing piece 2.
