Description

Technical Field

[0001] The utility model relates to the technical field of inspection, in particular to an inspection tool, in particular to a comprehensive inspection tool for a high-assembly slide block. Background Art

[0002] At present, as sliders are used in equipment in various industries, the output of sliders is also increasing. The demand for high stability of sliders requires the consistency of slider processing and production. For consistency, the key dimensions of sliders need to be inspected after production. Traditional slider inspection is manual inspection, which is time-consuming and labor-intensive, and the inspection efficiency and consistency cannot be guaranteed. How to quickly inspect has become the key when the output increases. Utility Model Content

[0003] The utility model aims to solve the problems existing in the above-mentioned prior art, and provides a comprehensive inspection tool for a high-assembly slider, so as to solve the problems of low slider inspection efficiency and inability to ensure consistency, and meet the needs of fast and stable inspection.

[0004] The utility model solves the technical problem by adopting the following technical solution: the comprehensive inspection tool for high-assembly slider comprises a base, a guide rail is fixed on the base, a slider to be inspected is movably connected on the guide rail, a left-right through groove is opened at the bottom of the slider, an inspection bearing for inspection located in the groove is horizontally rotatably connected on the base, a dial indicator is fixed on the base, the dial indicator head is arranged in contact with each end face of the slider to form a detection structure for the reference surface, and the outer diameter side end face of the inspection bearing forms a detection structure for judging the inspection result by whether it can pass according to the matching situation between the end face and the center side wall of the cavity when the slider passes through the groove. After such setting, the tooling of the present technical solution utilizes the actual fit between the slider and the guide rail for inspection. The end close to the inspection bearing is the sliding-in end of the slider. The far end distance of the outer diameter of the inspection bearing provided in the guide rail is slightly smaller than the size of the slider opening position. Whether the slider can pass smoothly is the basis for judging whether it is qualified. If the slider can pass smoothly, the center size of the cavity is within the tolerance range and is considered qualified. If it cannot pass, it is out of tolerance and is considered unqualified. When the slider slides to the other end, the difference between the workpiece and the sample can be measured by the dial indicator, and the position relationship between the center of the cavity and the corresponding reference surface can be indirectly judged, and then the inspection result is obtained.

[0005] As a further improvement of the utility model, at least one group of ball belts composed of balls rolling along the axial direction are rollingly connected on both sides of the slider, and the ball belts are rollingly connected and contacted with the inner wall of the center of the slider cavity, and the base is connected with an end cover circulator fixed at the front and rear ends of the guide rail, and the end cover circulator and the base are provided with hollow tracks to cooperate with the slider to form a ball circulation track for closed-loop rolling of the balls. The end cover circulators are connected to both ends of the guide rail, and tracks are provided in the end cover circulator and the base. The tracks of the end cover circulator, the base and the guide rail are connected to form a ball circulation track for closed-loop rolling of the balls. When the slider slides into the guide rail from one end, the balls will circulate through the end cover circulator along with the track. When the slider moves on the guide rail, the ball belt contacts the inner wall of the center of the slider cavity and makes the balls circulate in the ball circulation track to realize the rolling movement of the slider on the guide rail, thereby ensuring the smooth introduction and positioning accuracy of the slider.

[0006] As a further improvement of the present invention, the inspection bearing is located below the ball belt. The inspection bearing is composed of a pair of bearing units arranged front to back and staggered left to right. The bearing units perform matching tests on the inner wall of the center of the slider cavity separately in sequence. The inspection bearing is located below the ball belt to avoid interfering with the contact and operation between the ball belt and the inner wall of the center of the slider cavity. The front to back arrangement and staggered arrangement of the bearing units achieve matching tests on the inner wall of the center of the slider cavity separately in sequence, which can effectively understand which side has a problem, and then determine where the problem occurs, meeting the needs of efficient detection.

[0007] As a further improvement of the utility model, at least one bracket is fixed on the base, and the bracket is a Z-shaped structure, and the dial indicator can be fixed horizontally and vertically according to the position of the reference surface. The bracket is used to fix the dial indicator, and the Z-shaped structure of the bracket can provide horizontal and vertical fixing methods for the dial indicator, so that the same bracket can simultaneously check the position deviation of multiple reference surfaces relative to the center of the cavity, which can greatly improve the inspection accuracy and reduce additional repeated inspection operations.

[0008] As a further improvement of the utility model, the base is composed of an upper fixed plate and a lower fixed plate stacked up and down, and the ball circulation track is a circulation structure that goes from the guide rail through the end cover circulator, the upper fixed plate, the lower fixed plate, the upper fixed plate and the end cover circulator in sequence back to the guide rail. After such a configuration, the ball circulation track is composed of the guide rail, the end cover circulator, the upper fixed plate and the lower fixed plate connected together, and the subsequent maintenance and disassembly of the ball circulation track is simpler and faster, avoiding the situation where a large section of the ball circulation track is concentrated in one part, causing maintenance difficulties.

[0009] As a further improvement of the utility model, the inspection bearing is a butterfly bearing. Due to the unique contact surface narrowing structure, the butterfly bearing can ensure contact with the center inner wall of the cavity while reducing the contact area as much as possible, so as to ensure the inspection effect and reduce damage to the center inner wall of the cavity and play a certain protective role.

[0010] As a further improvement of the utility model, the dial indicator and the test bearing are staggered in front and back positions. After such arrangement, it is ensured that the dial indicator and the test bearing are not tested at the same time, but are tested separately in sequence, so as to achieve the accuracy and stability of the test.

[0011] The beneficial effects of the utility model are as follows: the utility model has a reasonable and compact structure, and can judge whether the center size of the cavity is qualified by checking the cooperation between the outer diameter end face of the bearing and the center inner wall of the slider cavity to check the passage condition. On the other hand, the difference between the workpiece and the sample can be measured by using the slider through a dial indicator, and the position relationship between the center of the cavity and the corresponding reference surface can be indirectly judged to obtain the inspection result. The slider cooperates with the guide rail and moves through the inspection bearing and dial indicator area respectively to obtain the corresponding inspection structure. The slider moves on the guide rail to ensure the smooth introduction and positioning accuracy of the slider, which helps to improve the inspection efficiency and effect, has a good use effect, and is suitable for promotion.
