[0001] The utility model relates to the technical field of manhole cover processing, in particular to a positioning device for manhole cover processing. Background Art

[0002] Manhole covers are used to cover deep wells in roads or homes to prevent people or objects from falling. They can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, etc. during production and processing to ensure the flatness of the manhole covers.

[0003] The Chinese patent "An external cylindrical grinding device for manhole cover processing" authorization announcement number "CN215317500U" clamps and positions the manhole cover through the second positioning plate and the first chuck and the second chuck on the surface of the first positioning plate, making it easy for people to install and grind the manhole cover, and then uses a grinding roller to grind the surface of the manhole cover to improve its efficiency.

[0004] However, in order to remove burrs and rough parts on the surface of the manhole cover during processing, its surface needs to be fully polished. When the manhole cover is clamped and polished using the first chuck and the second chuck, the burrs and rough parts at the contact point between the chuck and the manhole cover cannot be polished, thereby affecting the processing effect of the manhole cover.

[0005] Therefore, a positioning device for manhole cover processing is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a positioning device for manhole cover processing in order to solve the above-mentioned problem, thereby improving the problem that when the manhole cover is clamped and polished by the first chuck and the second chuck, the burrs and rough parts at the contact point between the chuck and the manhole cover cannot be polished, thereby affecting the processing effect of the manhole cover.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme: a positioning device for manhole cover processing, comprising: a base; a positioning mechanism, wherein the positioning mechanism for realizing positioning of the manhole cover processing is arranged at the top of the base; wherein the positioning mechanism comprises a motor fixedly connected to one side of the base, the inner wall of the base is rotatably connected with two bidirectional screw rods, one end of the two bidirectional screw rods passes through the base and are fixedly connected with gears, the surfaces of the two gears are meshingly connected, one end of one of the gears is fixedly connected to the output shaft of the motor, the top of the base is slidably connected with two first movable plates and two second movable plates, and a positioning component is arranged between the two second movable plates.

[0008] Preferably, the positioning assembly includes a fixed rod fixedly connected to one side of the first movable plate, the other end of the fixed rod is fixedly connected to the first disc, the other end of the first disc is fixedly connected to the first positioning rod, one side of the second movable plate is fixedly connected to two round rods, the other end of the round rod passes through the first movable plate and is fixedly connected to the second disc, the other end of the second disc is fixedly connected to the second positioning rod, the other end of the second positioning rod passes through the first disc, and the other ends of the first positioning rod and the second positioning rod are fixedly connected to the positioning plate. The inner wall of the first movable plate is bolted to the surface of one of the two-way screw rods, and the inner wall of the second movable plate is threaded to the surface of the other two-way screw rod. Under the action of the two gears, the first movable plate and the second movable plate are moved in opposite directions. When the manhole cover is fixed and the surface of the manhole cover is polished, the first positioning rod and the second positioning rod are switched to perform the polishing operation on the surface of the manhole cover, so that the positioning contact part of the manhole cover can be switched and polished, avoiding the generation of polishing dead angles during polishing, which is conducive to achieving comprehensive polishing of the surface of the manhole cover, thereby improving the polishing effect of the manhole cover.

[0009] Preferably, the inner wall of the positioning plate is provided with first circular grooves distributed in an annular shape, the inner wall of the first circular groove is slidably connected with a moving rod, and a spring is fixedly connected between one end of the moving rod and the inner wall of the first circular groove. When the surface of the manhole cover is uneven, when the positioning plate fixes the surface of the manhole cover, the moving rod contacts the groove on the surface under the action of the spring, thereby increasing the contact area between the surface of the positioning plate and the surface of the manhole cover when the surface of the manhole cover is uneven, increasing the stability of the positioning plate when fixing the manhole cover, and thus strengthening the fixing effect of the manhole cover when the manhole cover is polished.

[0010] Preferably, a mounting plate is fixedly connected to the middle of the top of the base, and two limit seats are slidably connected to the top of the mounting plate. When fixing the manhole cover, the limit seats are used to initially limit the manhole cover, thereby improving the stability of the manhole cover when it is fixed and avoiding the manhole cover from deflecting when it is fixed.

[0013] Preferably, the other end of the positioning plate is fixedly connected to a first rubber pad, and the surface of the first rubber pad is provided with grooves distributed in equal rows. When the positioning plate fixes the manhole cover, under the action of the first rubber pad, the friction between the positioning plate and the manhole cover is increased, and at the same time, the grooves on the surface of the first rubber pad are conducive to increasing the resistance between the first rubber pad and the manhole cover.

DETAILED DESCRIPTION

[0023] 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.

[0024] When implementing: Figure 1-5 As shown, a positioning device for manhole cover processing comprises: a base 1; a positioning mechanism 2, wherein the positioning mechanism 2 for realizing positioning of the manhole cover processing is arranged at the top of the base 1; wherein the positioning mechanism 2 comprises a motor 201 fixedly connected to one side of the base 1, and the inner wall of the base 1 is rotatably connected with two bidirectional screw rods 202, one end of the two bidirectional screw rods 202 passes through the base 1 and is fixedly connected with gears 203, the surfaces of the two gears 203 are meshingly connected, one end of one of the gears 203 is fixedly connected to the output shaft of the motor 201, and the top of the base 1 is slidably connected with two first movable plates 204 and two second movable plates 205, and a positioning assembly 206 is arranged between the two second movable plates 205.

[0025] The two first movable plates 204 and the two second movable plates 205 are all symmetrical with the center of the base 1, and the spacing between the two first movable plates 204 is greater than the spacing between the two second movable plates 205. When the manhole cover needs to be clamped, the motor 201 is started, and the output shaft of the motor 201 drives one of the gears 203 to rotate. Since the two gears 203 are meshed, when one of the gears 203 rotates, it drives the other gear 203 to rotate in the opposite direction, so that under the action of the two gears 203, the two bidirectional screw rods 202 rotate in opposite directions, so that the first movable plate 204 and the second movable plate 205 move in opposite directions. When the first movable plate 204 and the second movable plate 205 move in opposite directions, they will drive the corresponding positioning components to realize the positioning operation of the manhole cover.

[0026] like Figure 2 , Figure 3 and Figure 5As shown, the positioning assembly 206 includes a fixed rod 2061 fixedly connected to one side of the first movable plate 204, the other end of the fixed rod 2061 is fixedly connected to the first disc 2062, the other end of the first disc 2062 is fixedly connected to the first positioning rod 2063, one side of the second movable plate 205 is fixedly connected to two round rods 2064, the other end of the round rod 2064 penetrates the first movable plate 204 and is fixedly connected to the second disc 2065, the other end of the second disc 2065 is fixedly connected to the second positioning rod 2066, the other end of the second positioning rod 2066 penetrates the first disc 2062, and the other ends of the first positioning rod 2063 and the second positioning rod 2066 are fixedly connected to the positioning plate 2067. The inner wall of the first movable plate 204 is bolted to the surface of one of the two-way screw rods 202, and the inner wall of the second movable plate 205 is threaded to the surface of the other two-way screw rod 202. A mounting plate 209 is fixedly connected to the middle of the top of the base 1 , and two limit seats 2091 are slidably connected to the top of the mounting plate 209 .

[0027] The top of the base 1 is provided with a moving groove matching the first moving plate 204 and the second moving plate 205, and the top of the mounting plate 209 is provided with two moving grooves, which are symmetrical about the center of the mounting plate 209. The inner wall of the moving groove is slidably connected with a slider, and a limit seat 2091 is fixedly connected to the top of the corresponding slider. The inner wall of the limit seat 2091 is arc-shaped. When the manhole cover needs to be positioned, the two limit seats 2091 are moved. When the two limit seats 2091 are fitted to each other, the lower end of the manhole cover is placed in the two limit seats 2091. At this time, the motor 201 is started to make the output shaft of the motor 201 rotate forward. When the output shaft of the motor 201 rotates forward, it drives one of the bidirectional screw rods 202 to rotate forward, so that the two first moving plates 2 04 move and approach each other, and make the two first discs 2062 approach each other, the inner wall of the first disc 2062 is slidably connected to the surface of the second positioning rod 2066, and when the two first discs 2062 approach each other, the first positioning rod 2063 will be driven to move so that the positioning plate 2067 at the other end of the first positioning rod 2063 contacts with the manhole cover and realizes the fixing operation of the manhole cover. At the same time, under the action of another gear 203, the other bidirectional screw rod 202 rotates in the opposite direction, thereby driving the two second moving plates 205 to move and move away from each other, so that the second disc 2065 drives the second positioning rod 2066 away from the manhole cover. At this time, the limit seat 2091 under the manhole cover is moved to make the limit seat 2091 away from the manhole cover, and the manhole cover is polished.

[0028] When it is necessary to grind the contact portion between the positioning plate 2067 at the other end of the first positioning rod 2063 and the manhole cover, the two limit seats 2091 are moved to the bottom of the manhole cover to support the manhole cover. At this time, the motor 201 is rotated in the reverse direction, and the output shaft of the motor 201 drives one of the two-way screw rods 202 to rotate in the reverse direction, so that the two first moving plates 204 move away from each other. At this time, the first positioning rod 2063 releases the fixing operation on the manhole cover. At the same time, the other two-way screw rod 202 will rotate forward, thereby driving the two second moving plates 204 to move away from each other. The movable plate 205 moves and approaches each other. When the second movable plates 205 approach each other, the two second discs 2065 are driven to approach each other, so that the positioning plate 2067 at the other end of the second positioning rod 2066 contacts the manhole cover and realizes the fixing operation of the manhole cover. Therefore, when the second positioning rod 2066 fixes the manhole cover, the first positioning rod 2063 is away from the manhole cover, and the first positioning rod 2063 and the second positioning rod 2066 are staggered. At this time, the contact part between the positioning plate 2067 at the other end of the first positioning rod 2063 and the manhole cover can be polished.

[0029] like Figure 3 and Figure 4 As shown, the inner wall of the positioning plate 2067 is provided with a first circular groove 2069 distributed in an annular shape, and a moving rod 2068 is slidably connected to the inner wall of the first circular groove 2069, and a spring 20611 is fixedly connected between one end of the moving rod 2068 and the inner wall of the first circular groove 2069. The other end of the positioning plate 2067 is provided with a second circular groove 20610 distributed in an annular shape, and the second circular groove 20610 is connected to the first circular groove 2069. The other end of the moving rod 2068 passes through the second circular groove 20610, and the other end of the moving rod 2068 is fixedly connected to the second rubber pad 208. The other end of the positioning plate 2067 is fixedly connected to the first rubber pad 207, and the surface of the first rubber pad 207 is provided with grooves distributed in equal rows.

[0030] In the initial state, the moving rod 2068 extends to the outside of the second circular groove 20610 under the action of the spring 20611. When the positioning plate 2067 fixes the manhole cover, the other end of the moving rod 2068 first contacts the manhole cover. When the manhole cover is positioned, the moving rod 2068 will be squeezed to move the moving rod 2068 into the first circular groove 2069. The other end of the moving rod 2068 can be retracted to the second circular groove 20610 and be horizontal with the surface of the positioning plate 2067. The second rubber pad 208 can be retracted to the groove opened in the first rubber pad 207. When there is a groove on the surface of the manhole cover, the moving rod 2068 will enter the groove on the surface of the manhole cover under the action of the spring 20611, thereby increasing the contact area between the positioning plate 2067 and the surface of the manhole cover.

[0031] When the utility model is in use, when it is necessary to position the manhole cover, the limit seat 2091 is used to preliminarily limit the manhole cover, and the motor 201 is started, so that the output shaft of the motor 201 rotates forward to drive one of the two-way screw rods 202 to rotate forward, so that the two first movable plates 204 drive the first disc 2062 to move and approach each other, so that the positioning plate 2067 at the other end of the first positioning rod 2063 contacts the manhole cover and realizes the fixing operation of the manhole cover. At the same time, under the action of another gear 203, the other two-way screw rod 202 is rotated in the opposite direction, so that the two second movable plates 205 drive the second disc 2065 to move and move away from each other, so that the second positioning rod 2066 is away from the manhole cover. At this time, the limit seat 2091 under the manhole cover is moved to move the limit seat 2091 away from the manhole cover, and the manhole cover is polished.

[0032] When it is necessary to grind the contact portion between the positioning plate 2067 at the other end of the first positioning rod 2063 and the manhole cover, the two limit seats 2091 are used to support the manhole cover again. At this time, the motor 201 is rotated in the opposite direction to make one of the two-way screw rods 202 rotate in the opposite direction, driving the two first movable plates 204 to move and move away from each other so that the first positioning rod 2063 releases the fixation of the manhole cover. At the same time, the other two-way screw rod 202 will rotate forward to drive the second movable plate 205 to move the second disc 2065 and move closer to each other, so that the positioning plate 2067 at the other end of the second positioning rod 2066 contacts the manhole cover and fixes the manhole cover. At the same time, the first positioning rod 2063 is away from the manhole cover. At this time, the contact portion between the positioning plate 2067 at the other end of the first positioning rod 2063 and the manhole cover can be polished.

[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
