Description

Technical Field

[0001] The utility model relates to the technical field of guide rail detection, in particular to a guide rail channel detection device. Background Art

[0002] The function of linear guide motion is to support and guide moving parts to make reciprocating linear motion in a given direction. Linear guides are mainly used in mechanical structures with relatively high precision requirements. Instead of an intermediate medium, rolling steel balls are used between the moving and fixed elements of the linear guide.

[0003] The grooves of the guide rails are made by grinding with a grinding wheel. The grinding wheel will wear or be damaged as it is used, resulting in defects such as insufficient groove processing depth. Therefore, it is necessary to inspect the processed grooves. There are two main existing inspection methods: one is to remove the guide rails from the processing equipment after grinding, and use an imager, a profilometer or a three-coordinate inspection. However, the second clamping of the removed guide rails will result in errors with the first clamping position, so the guide rails cannot be clamped again for grinding correction; the second method is to use a standard slider to penetrate the slide rail for inspection. Although the removal of the guide rail is avoided, since the slider and the guide rail are in contact through the ball steel ball, only the contact position of the ball steel ball and the groove can be inspected, and the inspection is not comprehensive enough. Utility Model Content

[0004] The utility model aims at the above-mentioned deficiencies in the prior art and provides a guide rail groove detection device. The detection wheels can be clamped on both sides of the guide rail to detect the width of the guide rail. The profile of the convex ring is completely consistent with the guide rail groove, and the groove size can be detected. This not only improves the comprehensiveness of the detection, but also can detect processing defects without disassembling the guide rail, and can facilitate secondary grinding of the guide rail.

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

[0006] A guide rail channel detection device comprises a support block, wherein adjustable telescopic arms are respectively inserted at both ends of the support block, and the ends of the telescopic arms are connected to detection wheels through fixed blocks, and the side walls of the detection wheels cooperate with the side walls of the guide rails, and the outer side of the detection wheel is sleeved with a convex ring that cooperates with the guide rail channel.

[0007] Preferably, a slideway cooperating with the telescopic arm is provided in the support block, a rack is provided on the side wall of the telescopic arm, a gear meshing with the rack is provided between the two support arms, a cover plate is provided at the upper end of the telescopic arm, and a positioning bolt for fixing the telescopic arm is provided at the upper end of the cover plate.

[0008] Preferably, a handle is provided at the upper end of the cover plate.

[0009] Preferably, a limiting groove is provided on the inner wall of the slideway, and a limiting block cooperating with the limiting groove is provided on the side wall of the telescopic arm.

[0011] Preferably, the lower end of the fixed block is vertically connected to a wheel axle, and the detection wheel is connected to the wheel axle via a bearing.

[0012] Preferably, the two detection wheels are aligned left and right.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The detection wheel of the utility model can be clamped on both sides of the guide rail to detect the width of the guide rail. The profile of the convex ring is completely consistent with the guide rail groove, and the groove size can be detected, which not only improves the comprehensiveness of the detection, but also can detect processing defects without disassembling the guide rail, and can facilitate secondary grinding of the guide rail.

[0015] 2. The utility model can not only adjust the distance between the two detection wheels, but also replace the detection wheels, so as to adapt to different guide rail detection and increase the versatility of use.

[0016] 3. The two support arms of the utility model can be adjusted synchronously, which increases the adjustment speed and the convenience of fixing. At the same time, the two detection wheels can be symmetrically arranged, so that the force is more uniform when pushing the detection device to move, and the detection is smoother.

DETAILED DESCRIPTION

[0025] 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.

[0026] like Figure 1 As shown, a guide rail 5 channel detection device includes a support block 1, and adjustable telescopic arms 4 are respectively inserted at both ends of the support block 1. The ends of the telescopic arms 4 are connected to detection wheels 2 through fixed blocks 3. The two detection wheels 2 are aligned on the left and right, and the detection wheels 2 are clamped on both sides of the guide rail 5 and fit with the side walls of the guide rail 5. The outer side of the detection wheel 2 is covered with a convex ring 201 that matches the channel of the guide rail 5, and the convex ring 201 is completely fit with the inner wall of the channel. The distance between the two detection wheels 2 is adjusted by the telescopic arm 4.

[0027] like Figure 2-4 As shown, a slideway 104 cooperating with the telescopic arm 4 is provided in the support block 1, a rack 402 is provided on the side wall of the telescopic arm 4, and a gear 106 meshing with the rack 402 is provided between the two support arms to achieve synchronous adjustment of the two telescopic arms 4 and improve the adjustment speed. A cover plate 103 is provided at the upper end of the telescopic arm 4, and a positioning bolt 101 for fixing the telescopic arm 4 is provided at the upper end of the cover plate 103. The two telescopic arms 4 cooperate with each other through the gear 106. No matter which telescopic arm 4 is fixed, the positions of the two detection wheels 2 can be fixed. In order to improve the reliability of the fixation, two positioning bolts 101 are provided to fix the two telescopic arms 4 respectively.

[0028] In order to facilitate detection, a handle 102 is provided at the upper end of the cover plate 103 , and the handle 102 is used to push the detection device to slide along the guide rail 5 .

[0029] A limiting groove 105 is provided on the inner wall of the slideway 104 , and a limiting block 403 cooperating with the limiting groove 105 is provided on the side wall of the telescopic arm 4 , which can limit the maximum distance between the two detection wheels 2 and prevent the telescopic arm 4 from slipping off the support block 1 .

[0030] like Figure 5As shown, the end of the telescopic arm 4 is provided with a mounting groove 401. Figure 6 As shown, an insert block 301 matching with the mounting groove 401 is provided on the side wall of the fixing block 3 , and a tightening bolt 404 connected with the insert block 301 is provided on the side wall of the telescopic arm 4 , and the insert block 301 is fixed by the tightening bolt 404 .

[0031] The lower end of the fixed block 3 is vertically connected with the axle 202, and the detection wheel 2 is connected to the axle 202 through a bearing. Different sizes of guide rails 5 use different detection wheels 2. According to the model of the guide rail 5, the appropriate detection wheel 2 is selected. The convex ring 201 on each detection wheel 2 corresponds to a model of channel. The size of the convex ring 201 is completely matched with the standard channel.

[0032] like Figure 7 As shown, when performing the inspection, select the corresponding inspection wheel 2, then connect the fixed block 3 with the telescopic arm 4, fix it by tightening the bolt 404, adjust the distance between the two inspection wheels 2, and the minimum distance between the wheel surfaces of the two inspection wheels 2 is the same as the width of the standard guide rail 5. Insert the inspection device from one side of the guide rail 5, clamp the guide rail 5 with the two inspection wheels 2, match the convex ring 201 with the groove, and push the inspection device to move along the guide rail 5 by the handle 102. During the movement, if there is a non-standard processing on the guide rail 5, whether it is the width of the guide rail 5 or the size of the groove, the inspection device will be stuck at this position and cannot move, which means that the guide rail 5 is unqualified. If the inspection device can smoothly move from one end of the guide rail 5 to the other end, the inspection is qualified.
