Description

Technical Field

[0001] The utility model relates to a polishing piece positioning device, belonging to the technical field of polishing. Background Art

[0002] When polishing the plate, the plate is first transferred to the polishing station by a robot, and then the cylinder is used to drive the carrier with multiple vacuum suction cups to move upward. The vacuum suction cups are adsorbed on the plate to separate the robot from the plate, so that the multiple vacuum suction cups work together to position the plate. When the cylinder drives the carrier to move up and down, the hose connected to the hollow tube on the vacuum suction cup will rise and fall with the rise and fall of the carrier. At this time, the connection between the hose and the hollow tube will bend. As the number of times the carrier is lifted and lowered increases, the connection between the hose and the hollow tube will be damaged due to repeated bending, which affects the service life of the hose. Therefore, it is necessary to design a polishing part positioning device that can prevent the connection between the hose and the hollow tube from being damaged due to repeated bending. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model aims to provide a polishing part positioning device to solve the problems raised in the above-mentioned background technology. The utility model prevents the connection between the hose and the hollow tube from being damaged due to repeated bending, thereby extending the service life of the hose.

[0004] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a polishing part positioning device, comprising a base plate, two cylinders are symmetrically installed at the bottom of the base plate, a carrier plate is provided on the upper side of the base plate, the movable end of the cylinder passes through the base plate and is connected and fixed to the carrier plate, four through holes are evenly opened on the upper surface of the carrier plate, hollow tubes are installed in the through holes, a vacuum suction cup for adsorbing on the plate is installed on the upper end of the hollow tube, a hose for connecting the air inlet end of a vacuum pump is installed on the lower end of the hollow tube, two detachable vertical tubes are installed at both ends of the carrier plate, an adjusting rod is inserted in the vertical tube, a clamping screw for limiting the relative position of the adjusting rod and the vertical tube is threadedly connected to the outer surface of one end of the vertical tube away from the carrier plate, a first semicircular ring is connected and fixed to one end of the adjusting rod away from the vertical tube, a second semicircular ring is provided on the side of the first semicircular ring away from the adjusting rod, the two ends of the first semicircular ring are connected to the two ends of the second semicircular ring by bolts, and the hose passes through the space formed by the first semicircular ring and the second semicircular ring.

[0005] Furthermore, two support plates are connected and fixed at both ends of the carrier plate, a connecting plate is connected and fixed at one end of the vertical pipe, and the connecting plate is connected and fixed to the support plate by means of two sets of connecting screws and nuts.

[0006] Furthermore, a limiting ring for limiting the position of the head of the connecting screw is provided on the side of the connecting disk facing away from the support plate. There is a gap between the limiting ring and the connecting disk. The limiting ring is sleeved on the vertical pipe and fixedly connected to the vertical pipe. Two symmetrically arranged small holes are provided on one side of the limiting ring. One end of the connecting screw passes through the small hole, the connecting disk and the support plate and is threadedly connected with a nut.

[0007] Furthermore, both ends of the first semicircular ring are connected and fixed with first ears, and both ends of the second semicircular ring are connected and fixed with second ears, and the first ears are connected and fixed with the second ears by bolts.

[0008] Furthermore, two vertical holes are symmetrically opened at the bottom of the base plate, and the movable end of the cylinder passes through the vertical holes.

[0009] Furthermore, a threaded hole is formed on the outer surface of one end of the vertical pipe away from the carrier plate, and the clamping screw is threadedly connected in the threaded hole.

[0010] Beneficial effects of the utility model:

[0011] 1. When installing the vertical pipe on the carrier plate by means of connecting screws and nuts, one end of the connecting screw is passed through the small hole on the limiting ring, the connecting plate and the supporting plate in sequence, and then the nut is screwed on to complete the assembly of the vertical pipe and the carrier plate, which is convenient for the disassembly and assembly of the vertical pipe and the carrier plate. At this time, under the support of the limiting ring, a part of the rod of the connecting screw is exposed. When the connecting screw and the nut cannot be separated normally due to rust, the connecting screw can be cut off by using the gap between the connecting plate and the limiting ring.

[0012] 2. The first semicircular ring and the second semicircular ring are placed on the hose and the relative positions of the first semicircular ring, the second semicircular ring and the hose are kept unchanged. Then, under the support of the vertical pipe, the adjusting rod and other components, the connection part between the hose and the hollow tube is in a static state relative to the carrier plate. Then, when the carrier plate moves up and down, the connection part between the hose and the hollow tube will not bend, thereby preventing the connection part between the hose and the hollow tube from being damaged due to repeated bending.

[0013] 3. Adjust the length of the adjusting rod in the vertical pipe, and use the clamping screw to limit the relative position of the adjusting rod and the vertical pipe, so that the spacing between the first semicircular ring and the carrier plate changes, which is convenient for installing the structure formed by the first semicircular ring and the second semicircular ring in different areas of the hose. That is, when a certain part of the hose contacts with the structure formed by the first semicircular ring and the second semicircular ring for a period of time, the structure formed by the first semicircular ring and the second semicircular ring is moved to another part of the hose, so as to prevent the contact part of the hose with the structure formed by the first semicircular ring and the second semicircular ring from being bent and damaged for a long time, so that the hose is evenly worn and the service life of the hose is extended.
