Description

Technical Field

[0001] The present invention relates to the technical field of automobile production, in particular to a turntable, and more particularly to a four-sided turntable. Background Art

[0002] The four-sided turntable is also called a tetrahedron turntable. It is a device that can drive the equipment to be processed to rotate. It can be used in industrial automation production, and is widely used in the field of automobile manufacturing. It can be used in automobile body-in-white welding lines and hemming processes. The four-sided turntable has four independent workstations and can perform processing and assembly operations at the same time. The tetrahedron structure can improve production efficiency and can adapt to the process requirements of different models. It is driven by a servo motor and can achieve arbitrary angle segmentation and precise positioning, which is conducive to improving the convenience of processing.

[0003] For example, Chinese patent publication number CN110640692A discloses a tetrahedron servo turntable comprising a rotating table, a tool placement platform, and a separation plate. The tool placement platform is mounted on the rotating table, and the separation plate is mounted on the tool placement platform. The separation plate isolates the tool placement platform to form four independent tool placement positions, wherein each of the four isolated tool placement positions is equipped with a set of tooling equipment. This method enables the placement of four sets of tooling equipment on a single rotating table, enabling the simultaneous online production of four products and improving production efficiency.

[0004] The existing technical solution places four sets of tooling equipment on a turntable to meet the simultaneous online production of four products. In actual tests, it was found that this technical solution cannot automatically change the oil and clean the inside of the turntable at the bottom. The debris generated when the turntable is running accumulates in the mutually meshing or interconnected structures, which easily causes a problem of applying greater friction to the mutually meshing or interconnected structures, greatly increasing the probability of parts wear, which is not conducive to improving the service life of the turntable. At the same time, it is not possible to reduce the resistance encountered by the turntable during rotation to a greater extent, which is not conducive to reducing energy output and cannot achieve better energy saving. Therefore, it is necessary to propose a new solution to solve this problem. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a four-sided turntable, which can solve the problem that the existing technology cannot automatically change the oil and clean the inside of the turntable at the bottom, easily generates large friction on the mutually meshing or interconnected structures, which is not conducive to improving the service life of the turntable. At the same time, it cannot reduce the resistance encountered by the turntable during rotation to a greater extent, which is not conducive to reducing energy output and cannot achieve better energy saving.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical scheme: a four-sided turntable, comprising a shell, a detachable rotating assembly and an oil delivery assembly, the detachable rotating assembly being installed in the shell, the detachable rotating assembly comprising a fixed seat, a rotating seat and a top plate, the fixed seat being fixedly installed inside the shell, the rotating seat being located in the shell and between the fixed seat and the top plate, the top plate cover being arranged above the shell, the bottom of the shell being provided with a through hole 1, the upper part of the fixed seat and the lower part of the rotating seat being symmetrically provided with a slide groove 1, the fixed seat being provided with a through hole 2 connected with the slide groove 1, the upper part of the rotating seat and the bottom surface of the top plate being provided with a slide groove 2, the interior of the rotating seat being provided with a through hole 3 connected with the slide groove 1 and the slide groove 2, the oil delivery assembly comprising a box body 1, an oil pump and a pipeline 1, the oil pump being fixedly installed inside the box body 1, the pipeline 1 being fixedly installed between the oil pump and the top plate, and the pipeline 1 being fixedly passed through the top of the box body 1.

[0007] By adopting the above technical solution, when the rotating seat rotates, the rotating seat can drive the ball to rotate through the slide groove one and the slide groove two, and the ball and the slide groove one and the slide groove two can move relative to each other, and the ball and the slide groove one and the slide groove two produce mutual friction, which can produce metal debris products, and the rotation of the rotating seat is driven by the rotation of the worm to drive the rotor, and then the rotor drives the rotating seat to rotate through the rotating ring.

The mixed lubricating oil flowing into the first slide groove can be mixed with the lubricating oil mixed with debris on the surface of the ball inside the first slide groove and the slide groove, and then the mixed lubricating oil can flow into the inner bottom surface of the housing through the through-hole two. After the mixed lubricating oil flows to the surface of the rotor, it can be mixed with the lubricating oil mixed with debris on the surface of the rotor. Due to the relative movement of the rotor and the worm, the mixed lubricating oil can be mixed with the lubricating oil mixed with debris on the surface of the worm. The mixed lubricating oil can flow downward due to its fluidity and its own gravity. Then the mixed lubricating oil can flow into the inner bottom surface of the housing.

DETAILED DESCRIPTION

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom," "top," "inner," and "outer" refer to directions toward or away from the geometric center of a particular component, respectively.

[0022] like Figure 1-7As shown, a four-sided turntable includes a shell 1, a detachable rotating component 2 and an oil delivery component 3. The detachable rotating component 2 is installed in the shell 1. The detachable rotating component 2 includes a fixed seat 201, a rotating seat 202 and a top plate 203. The fixed seat 201 can support a pair of balls 9 through a slide groove 5. The rotating seat 202 can drive the rotating platform 14 to rotate through a bolt 15. The top plate 203 can limit the top of the rotating seat 202 to prevent the rotating seat 202 from accidentally moving up. The fixed seat 201 is fixed. The fixed device is arranged inside the shell 1, the rotating seat 202 is located inside the shell 1 and between the fixed seat 201 and the top plate 203, the top plate 203 is covered on the top of the shell 1, and a through hole 4 is opened at the bottom of the shell 1. The through hole 4 can facilitate the discharge of dirt inside the shell 1. A chute 5 is symmetrically opened above the fixed seat 201 and below the rotating seat 202. The chute 5 can facilitate the limiting of the ball 9 between the fixed seat 201 and the rotating seat 202. A through hole connected to the chute 5 is opened on the fixed seat 201. The through hole 26 can facilitate the outflow of the dirt inside the chute 1 5. The top of the rotating seat 202 and the bottom of the top plate 203 are both provided with a chute 27. The chute 27 can limit the ball 9 between the rotating seat 202 and the top plate 203. The rotating seat 202 is provided with a through hole 38 connected with the chute 1 5 and the chute 2 7. The through hole 38 can facilitate the outflow of the dirt inside the chute 2 7, and the through hole 38 can facilitate the entry of new lubricating oil into the chute 1 5. The oil delivery component 3 includes a box 1 301, an oil pump 302 and Pipe 1 303 and box 1 301 can be conveniently loaded with lubricating oil, and the oil pump 302 can drive the lubricating oil inside box 1 301 into pipe 1 303. Pipe 1 303 can drive the oil pump 302 to connect with the top plate 203. Pipe 1 303 can conveniently transport lubricating oil to the chute 2 7 on the top plate 203. The oil pump 302 is fixedly installed inside box 1 301, and pipe 1 303 is fixedly installed between the oil pump 302 and the top plate 203. Pipe 1 303 is fixedly passed through the top of box 1 301.

[0023] When the rotating seat 202 rotates, the rotating seat 202 can drive the ball 9 to rotate through the slide groove 1 5 and the slide groove 2 7, and the ball 9 and the slide groove 1 5 and the slide groove 2 7 can move relative to each other. The ball 9 and the slide groove 1 5 and the slide groove 2 7 produce mutual friction, and metal debris products can be produced after the mutual friction. The rotation of the rotating seat 202 is driven by the rotation of the worm 1204 to drive the rotor 1202, and then the rotor 1202 drives the rotating seat 202 to rotate through the rotating ring 1201. At this time, there is relative motion between the worm 1204 and the rotor 1202, and the relative motion between the worm 1204 and the rotor 1202 produces metal debris products. Friction is generated, and metal friction produces debris products. There is lubricating oil on the surface of the ball 9, the rotor 1202 and the worm 1204. The debris products can be mixed in the lubricating oil. The lubricity of the lubricating oil mixed with debris is reduced and it adheres to the surface of the structures that contact and move with each other, which easily leads to greater wear between the structures that contact and move with each other, which is not conducive to protecting the parts structure. By starting the oil pump 302, the new lubricating oil in the box body 301 is driven into the pipe 303. The new lubricating oil in the pipe 303 enters the space between the top plate 203 and the rotating seat 202 through the top plate 203. The lubricating oil in the chute 2 7 can flow to the surface of the ball 9 in the chute 2 7. The new lubricating oil flowing into the chute 2 7 can drive the lubricating oil mixed with debris to enter the chute 1 5 and the surface of the rotor 1202 through the through hole 3 8. The mixed lubricating oil flowing into the chute 1 5 can be mixed with the lubricating oil mixed with debris in the chute 1 5 and on the surface of the ball 9 in the chute 1 5. Then the mixed lubricating oil can flow into the inner bottom surface of the housing 1 through the through hole 2 6. After the mixed lubricating oil flows to the surface of the rotor 1202, it can mix with the lubricating oil mixed with debris on the surface of the rotor 1202. The lubricating oil is mixed, and due to the relative movement of the rotor 1202 and the worm 1204, the mixed lubricating oil can be mixed with the lubricating oil mixed with debris on the surface of the worm 1204, and the mixed lubricating oil can flow downward due to its fluidity and its own gravity, and then the mixed lubricating oil can flow into the inner bottom surface of the shell 1, and the mixed lubricating oil carrying debris can flow out of the shell 1 through the through hole 1 4, and the new lubricating oil in the continuous slide 2 7 can adhere to the slide 1 5 and the slide 2 7, and can adhere to the surface of the ball 9, the rotor 1202 and the worm 1204, which can reduce the friction caused by the debris.

[0024] like Figure 3-4 and Figure 6-7 As shown, balls 9 are installed in both the first slide 5 and the second slide 7. The balls 9 can be used to reduce the resistance encountered by the rotating seat 202 during rotation. The balls 9 are located in the housing 1 and are used to reduce the resistance encountered by the rotating seat 202 during rotation.

[0025] The top surface of the fixed seat 201 and the bottom surface of the rotating seat 202 are both provided with two slide grooves 5, and each slide groove 5 is equipped with multiple balls 9. The two circles of balls 9 in the two slide grooves 5 can support the bottom of the rotating seat 202 and help to improve the stability of the rotating seat 202. The bottom surface of the rotating seat 202 is close to the top surface of the fixed seat 201 but does not squeeze each other. The top surface of the rotating seat 202 and the bottom surface of the top plate 203 are both provided with slide grooves 27, and multiple balls 9 are installed inside the slide grooves 27. The balls 9 inside the slide grooves 27 can support the top of the rotating seat 202, which can prevent the top of the rotating seat 202 and the bottom surface of the top plate 203 from squeezing each other. The rotation of the balls 9 can cause relative movement with the slide grooves 1 5 and the slide grooves 2 7, and the round ball structure of the balls 9 can reduce the contact area between the slide grooves 1 5 and the slide grooves 2 7, thereby reducing the friction between the slide grooves 1 5 and the slide grooves 2 7, and the balls 9 can prevent the rotation The seat 202 is in direct contact with the fixed seat 201 and the top plate 203, which can help reduce the friction resistance of the rotating seat 202 to the top surface of the fixed seat 201 and the bottom surface of the top plate 203 when the rotating seat 202 rotates. When the rotating seat 202 rotates around its own central axis, due to the ring structure of the rotating seat 202, the slide 1 5 and the slide 2 7, the central axis of the rotating seat 202 coincides with the central axis of the slide 1 5 and the slide 2 7, and the rotation of the rotating seat 202 can drive the slide 1 5 and the slide 2 The first and second chute 7 rotate around their own central axis, and the chute 1 5 and the second chute 7 are squeezed against the ball 9. The chute 1 5 and the second chute 7 can drive the ball 9 to roll, and can drive the ball 9 to rotate around the central axis of the rotating seat 202 in the chute 1 5 and the second chute 7. The relative movement of the ball 9 and the chute 1 5 and the second chute 7 combined with the lubrication of the surface of the ball 9 and the lubricating oil in the chute 1 5 and the second chute 7 can fully reduce the friction resistance encountered by the rotating seat 202 when it rotates.

[0026] like Figure 1-3 and Figure 6 As shown, a collecting component 10 is installed at the bottom of the shell 1, and the collecting component 10 is used to collect dirt. The collecting component 10 includes a base 1001, and the base 1001 can support the bottom of the shell 1. The base 1001 is fixedly sleeved at the bottom of the shell 1, and a cavity 11 is provided between the base 1001 and the shell 1. A pipe 2 1002 is fixedly penetrated on the base 1001, and the pipe 2 1002 can facilitate the outflow of the mixed lubricating oil carrying debris in the cavity 11. The top of the pipe 2 1002 is connected to the bottom surface of the cavity 11, and the lower end of the pipe 2 1002 is fixedly provided with a box 2 1003, and the box 2 1003 can facilitate the storage of the mixed lubricating oil carrying debris.

[0027] The base 1001 supports the bottom of the shell 1, which is beneficial to improving the stability of the shell 1. When the mixed lubricating oil carrying debris inside the shell 1 flows out through the through hole 1 4, the mixed lubricating oil carrying debris through the through hole 1 4 flows into the cavity 11, and the mixed lubricating oil carrying debris inside the cavity 11 enters the pipe 2 1002. The mixed lubricating oil carrying debris in the pipe 2 1002 flows downward and enters the box 2 1003. The box 2 1003 can collect the mixed lubricating oil carrying debris.

The rotating ring 1201 is fixedly sleeved on the outside of the rotating seat 202. The side wall of the ring 1201 is arranged in a ring with a rotor 1202. The rotation of the rotor 1202 can drive the rotating ring 1201 to rotate. The power structure includes a servo motor 1203 and a worm 1204. The servo motor 1203 can drive the worm 1204 to rotate. The rotation of the worm 1204 can drive the rotor 1202 to rotate. The servo motor 1203 is fixedly mounted on the outer side wall of the shell 1. The worm 1204 is fixedly connected to the output shaft of the servo motor 1203. The worm 1204 is engaged with the rotor 1202 through the groove 13. The rotating ring 1201, the rotor 1202 and the worm 1204 are all located in the shell 1.
