Description

Technical Field

[0001] The present application relates to the field of measurement technology, and in particular to a retaining fixture for measuring a slider. Background Art

[0002] With the continuous development of slider production technology, in order to ensure the accuracy of measuring the dimensions of each part of the slider, the slider needs to be installed on the guide rail before measurement, so as to measure the distance between the bottom of the guide rail and the top surfaces on both sides of the slider, as well as the distance between the two outer walls of the slider and the opposite side walls of the guide rail when the slider can run smoothly after being installed on the guide rail.

[0003] When the existing slider is installed on the guide rail, it needs to be installed with the cooperation of the retaining frame. The retaining frame includes multiple parts such as the retaining frame body and the circulator. A circulating raceway for the ball bearings to reciprocate and roll is formed between the retaining frame body, the circulator and the guide rail, so that the slider can slide smoothly with the guide rail with the cooperation of the ball bearings. During the installation of the slider, the ball bearings can easily slip out from between the retaining frame body and the circulator, which makes the installation and disassembly of the slider difficult during the slider measurement process, requiring more time and manpower. After the measurement, the slider needs to be disassembled for cleaning and then assembled, increasing the company's production costs. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the installation and disassembly of the existing sliding block is time-consuming and laborious during measurement, resulting in poor efficiency of the sliding block measurement operation.

[0005] To this end, the utility model provides a holding fixture for measuring a slide block.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A retaining fixture for measuring a slider, the retaining fixture is installed between a guide rail and a slider, and is used to measure the installation dimensions between the slider and the guide rail. The retaining fixture comprises: a frame, the frame is sleeved on the guide rail and arranged between the guide rail and the slider, and a ball is embedded in the frame, and the ball and the guide rail are in rolling cooperation.

[0008] By adopting the above technical solution, the ball is embedded in the frame, and the ball can roll in situ on the frame, so that the ball is not easy to fall off the frame during installation and disassembly, and the slider can be mounted on the frame without complicated assembly, and relative movement with the guide rail can be achieved, and the verticality and horizontality of the rolling guide pair can be guaranteed, so that the measurement of the slider is simple and convenient, the labor cost and process cost are reduced, and the efficiency of the slider measurement operation is improved.

[0009] Furthermore, a ball-catching groove is provided on the frame body, and the ball-catching groove is configured to be spherical. The ball-catching groove wraps the ball on the frame body, and part of the ball protrudes from the notch of the ball-catching groove.

[0010] Furthermore, the diameter of the ball-locking groove is greater than the diameter of the ball.

[0011] Furthermore, the frame body is provided with a ball plugging opening connected to the ball-locking groove, and the diameter of the ball plugging opening is smaller than the diameter of the ball.

[0012] Furthermore, the ratio of the diameter of the ball plug opening to the diameter of the ball is less than 1 and greater than 0.9.

[0013] Furthermore, the ball plugging opening and the ball locking groove are arranged perpendicular to the length direction of the guide rail.

[0014] Furthermore, the ball plug opening is located in the vertical direction of the line connecting the three points of the guide rail channel center, the ball center and the slider channel center.

[0015] By adopting the above technical solution, the ball is inserted into the ball retaining groove from the ball plugging opening. Since the ball plugging opening is located in the ball retaining groove perpendicular to the length direction of the guide rail, when the slider and the frame move in a straight line along the guide rail, the possibility of the ball moving along the length direction of the guide rail is reduced, and the ball plugging opening does not affect the movement of the ball in the channel.

[0016] Furthermore, a channel portion is provided on the frame, and the channel portion is adapted to the groove on the guide rail.

[0017] Furthermore, the ball-locking groove is arranged on the channel portion.

[0018] Furthermore, the frame body includes a top frame and two side frames, the top frame is located at the top of the guide rail, and the side frames are respectively located on both sides of the guide rail.

[0019] Furthermore, an end cover is provided at the end of the frame, and the end cover is covered on the end surface of the slider.

[0020] Furthermore, the ends of the top frame, the side frame and the channel portion are all connected with extended ends, and the extended ends are connected to the end covers.

[0021] Furthermore, the extended end and the end cover are integrally formed.

[0022] By adopting the above technical solution, the split structure of the main body of the clamp is retained, which saves the step of grinding the side of the guide rail for some large-sized guide rails, so that the clamp can be directly put on the guide rail. Due to the existence of the end cover, the frame with the split structure is installed as an integral part through the end cover, and the extended end and the end cover are arranged as an integral whole, so the structure is stable and the service life is long.

[0023] The beneficial effect of the utility model is that the present application adopts a retaining fixture set on the guide rail, and the slider and the retaining fixture are moved along the length direction of the guide rail by limiting the end cover on the retaining fixture and the slider. The ball is embedded in the frame through the ball clamping groove, so that the ball is not easy to fall out during the installation and removal of the structure, and the ball clamping groove and the ball plugging port are designed separately to make it easier to remove the ball, thereby improving the efficiency of the slider measurement.

[0024] The frame structure adopts a split structure, and the four channel parts are designed separately. The overall installation of the split structure is achieved by plugging the end cover and the extension part, so that some large-sized guide rails can be fitted with fixtures without grinding the side surfaces.

[0036] Reference Figure 1-6 A holding fixture for measuring a slider, the holding fixture 3 includes a frame 30 and an end cover 31. When in use, the holding fixture 3 is sleeved on the guide rail 2 and is arranged between the slider 1 and the guide rail 2.

[0037] The frame body 30 includes a top frame 301 and two side frames 302. The side frames 302 are respectively arranged on both sides of the guide rail 2. The top frame 301 is arranged on the top of the guide rail 2. A plurality of channel portions 303 are arranged on the frame body 30. The channel portions 303 are adapted to the grooves on the guide rail 2. The channel portions 303 on the top frame 301 are arranged along the length direction of the guide rail 2 and connected to both sides of the top frame 301. The channel portions 303 on the side frame 302 are arranged on one side of the side frame 302 close to the top frame 301. The top frame 301, the side frame 302 and the channel portions 303 form the main body of the retaining clamp 3.

[0038] A ball 4 is embedded in the channel portion 303. It should be noted that when the slider 1 and the retaining clamp 3 move linearly along the guide rail 2, the ball 4 maintains a relative position with the retaining clamp 3 unchanged and rolls with the retaining clamp 3, thereby rolling with the guide rail 2.

[0039] In this embodiment, two channel portions 303 are provided on each of the two side edges of the frame 30, and a card slot is provided on the channel portion 303. Each group of card slots includes a plurality of ball-locking grooves 32 arranged along the length direction of the frame 30. The ball-locking grooves 32 are configured as spherical grooves. The ratio of the diameter D1 of the ball-locking groove 32 to the diameter Dball of the ball 4 is greater than 1, so that the ball 4 can be stably embedded in the ball-locking groove 32 without falling out, and the ball 4 can roll smoothly in the ball-locking groove 32. The ball-locking groove 32 wraps the ball 4 on the frame 30, and part of the ball 4 protrudes from the notch of the ball-locking groove 32 and rolls with the side wall of the guide rail 2. Since the clamp has no contact with the guide rail 2 and the slider 1, and the ball 4 is in close contact with the guide rail 2 and the slider 1, the ball 4 rolls smoothly.

[0040] The frame 30 is provided with a ball plugging opening 33 corresponding to the ball clamping groove 32, the ball plugging opening 33 is connected with the ball clamping groove 32, and the ball plugging opening 33 is located in the vertical direction of the line connecting the three points of the channel center of the guide rail 2, the center of the ball 4 and the center of the channel of the slider 1. The line between the ball plugging opening 33 and the ball clamping groove 32 is perpendicular to the length direction of the guide rail 2, so that when the slider 1 and the frame 30 move linearly along the guide rail 2, the possibility of the ball 4 moving along the length direction of the guide rail 2 is reduced, and the ball plugging opening 33 does not affect the movement of the ball 4 in the channel. The ratio of the diameter D2 of the ball plugging opening 33 to the diameter D of the ball 4 is less than 1 and greater than 0.9, which can make it easier to remove and install the ball.

[0041] The end of the main part of the holding fixture 3 is connected with an extension end 34, and the extension end 34 is connected to the end cover 31. Preferably, the extension end 34 and the end cover 31 are integrally formed. Due to the existence of the end cover 31, the frame body 30 with a split structure is installed as a whole through the end cover 31. For some large-sized guide rails 2, the split structure of the main part of the holding fixture 3 saves the step of grinding the side of the guide rail 2, so that the holding fixture 3 can be directly put on the guide rail 2. Due to the existence of the end cover 31, the frame body 30 with a split structure is installed as a whole through the end cover 31. The extension end 34 and the end cover 31 are integrally set, and the structure is stable and has a long service life.

[0042] The frame 30 is installed between the slider 1 and the guide rail 2. The frame 30 is sleeved on the guide rail 2. The extended end 34 protrudes from the end of the slider 1. The end cover 31 is covered on one end of the slider 1. The end cover 31 is connected to the frame 30 by plugging the extended end 34 and the end cover 31, so that the slider 1 cannot easily slide relative to the fixture.

[0043] After the frame 30 is installed between the slider 1 and the guide rail 2, refer to Figure 3 , measure the distances M1 and M2 between the bottom surfaces of the guide rail 2 and the top surface of the slider 1 , and measure the distances W1 and W2 between the side walls of the guide rail 2 and the corresponding outer side walls of the slider 1 .

[0044] In summary, the fixture is easy to install and provides accurate measurement data, which can improve production efficiency and reduce company costs.

[0045] The present application adopts a retaining fixture 3 sleeved on the guide rail 2, and the slider 1 and the retaining fixture 3 are limited by the end cover 31 on the retaining fixture 3 and the slider 1, so that the slider 1 and the retaining fixture 3 move along the length direction of the guide rail 2. The ball 4 is embedded in the frame 30 through the ball-locking groove 32, so that the ball 4 is not easy to fall out during the installation and removal of the structure, and the ball-locking groove 32 and the ball plugging port 33 are designed separately to make it easier to remove the ball 4, thereby improving the efficiency of measuring the slider 1.

[0046] In the prior art, in order to realize the installation of parts such as circulators between the slider 1 and the guide rail 2, it is necessary to grind the two sides of the guide rail 2 before installing the fixture to achieve the purpose of placing the parts, and the grinding accuracy is required to be high, which increases the cost. In the present application, the frame 30 structure adopts a split structure, and the four channel parts 303 are designed separately. The overall installation of the split structure is realized through the end cover 31 and the extension end 34, so that some large-sized guide rails 2 can be put on the fixture without grinding the side.
