Description

Technical Field

[0001] The utility model belongs to the technical field of bearing seats, and in particular relates to a linear bearing fixed seat slide block. Background Art

[0002] Linear bearing seats are a kind of linear motion system produced at low cost, which are used in conjunction with cylindrical shafts with unlimited stroke. Since the bearing ball is in point contact with the shaft, the load is small, and the steel ball rotates with very little friction resistance, so that high-precision and smooth motion can be obtained. However, the existing linear bearing seats cannot be installed with linear bearings of different models, which reduces the applicability of linear bearing seats and brings inconvenience to production work.

[0003] However, there are some problems in the prior art: when the slider needs to be disassembled, the linear shaft needs to be disassembled from the fixed seat first before the slider can be disassembled, which is time-consuming and laborious. Therefore, we propose a linear bearing fixed seat slider. Utility Model Content

[0004] In view of the problems existing in the above-mentioned technology, the utility model provides a linear bearing fixed seat slider, which solves the problem that when the slider needs to be disassembled, the linear shaft needs to be disassembled from the fixed seat first before the slider can be disassembled, which is time-consuming and laborious.

[0005] The utility model is implemented as follows: a linear bearing fixed seat slider comprises an upper frame body and a lower frame body, and a center hole is reserved on one side where the upper frame body and the lower frame body are connected. The center hole comprises an upper semicircular groove arranged on the lower end surface of the upper frame body and a lower semicircular groove arranged on the upper end surface of the lower frame body. The lower end surface of the upper frame body is symmetrically connected with a clamping plate, and the upper end surface of the lower frame body is symmetrically connected with a limit plate, the limit plate and the clamping plate are clamped to each other, and the limit plate and the clamping plate are both located on the left and right sides of the center hole, the upper frame body and the lower frame body are clamped to each other through the cooperation of the limit plate and the clamping plate, and two groups of limit assemblies are symmetrically arranged on the upper end of the lower frame body, the limit assembly is located at the lower end of the limit plate, the limit assembly passes through the limit plate and the clamping plate, and the lower frame body is fixedly connected to the upper frame body through the set limit assembly.

[0006] As a preferred embodiment of the present invention, the cross-section of the card plate is arranged in an L shape, a first card groove for limiting the limit plate is reserved between the card plate and the upper frame, and a group of positioning holes is provided on the lower end surface of the card plate.

[0007] As a preferred embodiment of the present invention, a group of pin holes are provided on the outer walls on the left and right sides of the upper frame.

[0008] As a preferred embodiment of the present invention, the cross-section of the limit plate is arranged in an L-shape, and a second clamping groove for limiting the clamping plate is reserved between the limit plate and the lower frame.

[0009] As a preferred embodiment of the utility model, a group of limiting holes are provided on the upper end surface of the limiting plate, and a group of through holes are provided on the outer wall of one side of the limiting plate away from the lower semicircular groove, and the through holes are connected to the limiting holes and correspond to the pin holes.

[0010] As a preferred embodiment of the utility model, the limiting assembly includes a telescopic hole arranged on the upper end surface of the lower frame, a telescopic block is connected to the inside of the telescopic hole, one end of the telescopic block located inside the telescopic hole is connected to a spring, and the other end of the telescopic block extends out of the telescopic hole.

[0011] As a preferred embodiment of the present invention, a group of fixing pins are provided on the outer walls on the left and right sides of the upper frame.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The upper frame and the lower frame of the utility model are installed on the straight axis, and the clamping plate and the limit plate cooperate with each other to limit the upper frame and the lower frame, and the limit plate and the clamping plate are fixed by the limit assembly, so as to realize the assembly between the upper frame and the lower frame, which is convenient for installation on the straight axis. The slider adopts an assembly structure, which is convenient for the slider to be disassembled and assembled on the straight axis, with a simple structure, convenient operation, and quick disassembly and assembly;

[0014] 2. When the upper frame and the lower frame are assembled, the limit plate slides into the first slot, so that the telescopic block contacts the card plate and is subjected to force, driving the spring to contract toward the telescopic hole. When the limit plate and the card plate are completely located in the first slot and the second slot, the upper frame and the lower frame are arranged in a rectangular shape, such as Figure 1 As shown, the telescopic hole, the limiting hole and the positioning hole are arranged in a vertical straight line. When the telescopic block is not pressed by the clamping plate, the spring rebounds, driving the telescopic block to pass through the positioning hole and extend into the limiting hole, thereby fixing the upper frame and the lower frame, and improving the stability of the connection between the two.

[0015] 3. The utility model uses a fixed pin externally arranged on the slider, and the fixed pin is inserted into the pin hole, passes through the through hole and extends into the limiting hole. Since the head of the telescopic block is arranged in a semicircular shape, when the fixed pin moves toward the limiting hole, the telescopic block is subjected to the moving force of the fixed pin, moves downward inside the limiting hole, and moves to the inside of the positioning hole, thereby facilitating the sliding of the upper frame and driving the positioning hole to move. When the positioning hole is away from the limiting hole, the telescopic block is affected by the contact force with the card plate, driving the spring to contract toward the inside of the step hole, thereby facilitating disassembly and assembly between the upper frame and the lower frame.

The slider adopts an assembly structure, which is convenient for the slider to be disassembled and assembled on the straight axis, with a simple structure, convenient operation, and quick disassembly and assembly.

[0025] like Figure 2 and Figure 4 As shown, the cross-section of the card plate 13 is arranged in an L shape, and a first card groove 11 for limiting the limit plate 22 is reserved between the card plate 13 and the upper frame body 1, and a group of positioning holes 131 are provided on the lower end surface of the card plate 13; a group of pin holes 14 are provided on the outer walls on the left and right sides of the upper frame body 1; the cross-section of the limit plate 22 is arranged in an L shape, and a second card groove 23 for limiting the card plate 13 is reserved between the limit plate 22 and the lower frame body 2; a group of limiting holes 222 are provided on the upper end surface of the limit plate 22, and a group of through holes 221 are provided on the outer wall on the side of the limit plate 22 away from the lower semicircular groove 21, and the through holes 221 are connected with the limiting holes 222 and correspond to the pin holes 14; the card plate 13 extends into the second card groove 23, and the limiting plate 22 extends into the first card groove 11, which is convenient for realizing assembly limit between the upper frame body 1 and the lower frame body 2, and convenient for the slider to be installed on the straight axis, and the installation structure is simple and convenient.

One end of the telescopic block 43 located inside the telescopic hole 42 is connected to a spring 41, and the other end of the telescopic block 43 extends out of the telescopic hole 42; when the upper frame 1 and the lower frame 2 are assembled, the limit plate 22 slides into the first card slot 11, so that the telescopic block 43 contacts the card plate 13 and is subjected to force, driving the spring 41 to shrink into the telescopic hole 42.
