Technical Field

[0001] The invention relates to the technical field of machine tools and automation equipment, and in particular to a connection structure between a slideway bar of a slide block and a slide block housing. Background Art

[0002] Linear motion pairs (linear rail sliders) are widely used in machine tools, molds, automation equipment, and also in the field of robots. They are used to achieve high-precision, heavy-load linear motion. They can also be used in crank slider mechanisms to convert rotary motion into linear motion. In addition, sliders are also used in mold opening operations, and can slide perpendicularly or at a certain angle to help the mold to be demolded normally.

[0003] The slider structure on the market is basically one-piece, which is difficult to process during production, has low material utilization and high cost. The relative displacement and wear between the ball and the slider over a long period of time will increase the deformation of the contact between the slider and the ball, making the ball movement unstable. In addition, the slider in the prior art is very noisy during high-speed operation. Summary of the invention

[0004] In order to solve the technical problems existing in the prior art, an embodiment of the present invention provides a connection structure between a slide rail of a slider and a slider housing. The technical solution is as follows:

[0005] A connection structure between a slideway bar of a slider and a slider housing comprises: a slider housing and a slider bar, wherein a tin-containing point is arranged on the inner wall of the slider housing, and the slider bar is welded to the slider housing through a tin film.

[0006] Optionally, the slider housing is an inverted concave-shaped block, and two first grooves are provided on two opposite inner side walls of the open end of the slider housing.

[0007] Optionally, the two first grooves are symmetrically arranged, and a slider bar mounting groove is connected between the two first grooves.

[0008] Optionally, the sliding block includes a slide bar body, a recessed portion is provided on one side of the slide bar body, a protruding portion is provided on the other side, the connection between the protruding portion and the slide bar body is arc-shaped, a second groove is provided on the protruding portion, and third grooves are provided at both upper and lower ends of the slide bar body, and the slide bar is symmetrical along the axis of the slide bar.

[0009] Optionally, at least three tin-containing points are arranged in the slide bar installation groove.

[0010] Optionally, a first tin-containing point, a second tin-containing point and a third tin-containing point are set in the slide bar installation groove; the slide bar is connected to the slide bar installation groove through the first tin-containing point, the second tin-containing point and the third tin-containing point.

[0011] Optionally, a first tin-containing point is connected between the recessed portion and the concave point of the slide bar installation groove, and the first tin-containing point fills the gap between the recessed portion and the concave point of the slide bar installation groove.

[0012] Optionally, a fifth groove is set in the middle of the inner wall on one side of the slide bar installation groove, and a sixth groove is set in the middle of the inner wall on the other side of the slide bar installation groove, and the outer walls on both sides of the recessed portion of the slide bar body are respectively fitted with the inner walls on both sides of the slide bar installation groove, and the two fitting surfaces located on both sides of the fifth groove are respectively the first mating surface and the second mating surface, and the two fitting surfaces located on both sides of the sixth groove are respectively the third mating surface and the fourth mating surface, the second tin-containing point fills the fifth groove, and the third tin-containing point fills the sixth groove, so that the outer wall of the slide bar is connected to the inner wall of the slide bar installation groove through the second tin-containing point and the third tin-containing point.

[0015] The beneficial effects brought about by the technical solution provided by the embodiment of the present invention include at least:

[0016] The technical solution of the present invention divides the originally integrally formed slider into two parts, namely a slider housing and a slide bar, which reduces the processing difficulty, improves material utilization and thus reduces costs. The present solution adopts pressure soldering technology to weld the slider housing and the slide bar through a tin film, which increases firmness. When the ball and the slide bar are relatively displaced, the deformation of the slide bar is small, making the operation of the ball and the slider more stable when they are relatively displaced. The tin film is beneficial to sound insulation and reduces the noise during the operation of the slider. Moreover, since the slide bar and the slider housing are firmly connected through the tin film, the relative displacement between the slider housing and the slide bar is reduced.

[0025] like Figure 1-Figure 2As shown, a connection structure between a slide bar of a slider and a slider shell is provided, including a slider shell 2 and a slide bar 1. The slider shell 2 and the slide bar 1 are welded together by pressure soldering technology, and a tin film formed between the slider shell 2 and the slide bar 1 connects the two together.

[0026] The slider housing 2 is an inverted concave block, and two first grooves are provided on the two opposite inner walls of the open end of the slider housing 2. The two first grooves are symmetrically arranged, and a slider bar mounting groove is connected between the two first grooves on each inner wall of the slider housing 2. The two first grooves are used to cooperate with the ball bearings.

[0027] The slider bar 1 includes a slide bar body, one side of the slide bar body is convex, a plane is provided at the end of the convex part, a recessed part is provided in the middle of the plane, a convex part is provided on the other side of the slide bar body, the connection between the convex part and the slide bar body is arc-shaped, a second groove is provided on the convex part, and a third groove is provided at both the upper and lower ends of the slide bar body, and the cross section of the slide bar 1 is symmetrical along the axis of the slide bar 1. The connection between the slide bar body and the plane where the recessed part is provided is a smooth inclined wall, that is, the outer side walls of the slide bar on both sides of the plane where the recessed part is provided are smooth inclined walls.

[0028] At least three tin-containing points are arranged in the slide bar installation groove. In this embodiment, there are three tin-containing points, namely the first tin-containing point 3, the second tin-containing point 5 and the third tin-containing point 4. The plane of the slide bar 1 and the outer walls on both sides of the plane are welded to the slide bar installation groove through the first tin-containing point 3, the second tin-containing point 5 and the third tin-containing point 4.

[0029] A first tin-containing point 3 is connected between the plane of the slide bar 1 and the concave point of the slide bar installation groove, and the first tin-containing point 3 fills the gap between the plane and the concave point of the slide bar installation groove. A fifth groove is set in the middle of the inner wall on one side of the slide bar installation groove, and a sixth groove is set in the middle of the inner wall on the other side of the slide bar installation groove. The outer walls on both sides of the plane of the slide bar body are respectively fitted with the inner walls on both sides of the slide bar installation groove, and the two fitting surfaces on both sides of the fifth groove are respectively the first mating surface 6 and the second mating surface 7, and the two fitting surfaces on both sides of the sixth groove are respectively the third mating surface 8 and the fourth mating surface 9. The second tin-containing point 5 fills the fifth groove, and the third tin-containing point 4 fills the sixth groove, so that the outer walls on both sides of the plane of the slide bar 1 are connected to the inner wall of the slide bar installation groove through the second tin-containing point 5 and the third tin-containing point 4. The pressure soldering technology forms a tin film on the first mating surface 6, the second mating surface 7, the third mating surface 8 and the fourth mating surface 9, and the tin film tightly connects the slider bar 1 and the slider housing 2.

[0030] The first soldering point 3 is symmetrical with respect to the axis of the slide bar installation slot, and the third soldering point 4 and the second soldering point 5 are symmetrical with respect to the axis of the slide bar installation slot. A slide bar 1 is installed on each of the two inner side walls of the slider housing 2.

[0031] This solution divides the originally one-piece slider into two parts, a slider housing and a slide bar, which reduces the processing difficulty, improves material utilization and thus reduces costs. This solution uses pressure soldering technology to weld the slider housing and the slide bar through a tin film, which increases firmness. When the ball and the slide bar are relatively displaced, the deformation of the slide bar is small, making the operation of the ball and the slider more stable when they are relatively displaced. The tin film is beneficial for sound insulation and reduces the noise during the operation of the slider. Moreover, since the slide bar and the slider housing are firmly connected through the tin film, the relative displacement between the slider housing and the slide bar is reduced.

[0032] In the prior art, the slide bar is under a certain load during operation and will be deformed. By welding in this solution, the slider housing and the slide bar are matched without gap, thereby reducing the micro-deformation of the slide bar under heavy load.
