Description

Technical Field

[0001] This utility model relates to the field of mechanical parts processing technology, and in particular to a fixing device for machining slewing bearings that is easy to adjust. Background Technology

[0002] Slewing bearings, also known as turntable bearings, are large bearings capable of withstanding comprehensive loads. They consist of inner and outer rings, rolling elements, etc. They can simultaneously withstand large axial and radial loads and overturning moments. They are essential transmission components for machines that require relative rotational motion between two objects and simultaneously withstand these forces, and are often referred to as "the joints of machines".

[0003] Chinese Patent Publication No. CN217167724U discloses a slewing bearing machining fixture, including a machine body and a lubrication device. A positioning clamp is provided on the surface of the machine body. The lubrication device is located on the surface of the machine body and includes a storage box fixedly connected to the machine body. A discharge port is opened on one side of the storage box, and a mounting block is fixedly connected to one side of the storage box. A cover plate is rotatably connected to the surface of the mounting block. A hole is opened on the surface of the cover plate, which engages with the discharge port. A circular rod is fixedly connected to one side of the cover plate. A groove is opened on one side of the storage box, and a mounting plate is slidably connected to the inner wall of the groove. A hole is opened on the surface of the mounting plate, and the circular rod engages with the hole. By providing a lubrication device, the positioning clamp is effectively lubricated, increasing the ease of use of the equipment, reducing wear, decreasing the failure rate, and improving the working efficiency of the equipment.

[0004] While existing patents can reduce wear and tear on equipment, the inability to adjust the height of the slewing bearing when it is fixed reduces the flexibility of operators during processing, thus affecting work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a fixing device for machining slewing bearings that is easy to adjust, which solves the problem in the prior art that the height of the slewing bearing cannot be adjusted when it is fixed, thus reducing the flexibility of the operator during machining.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fixing device for machining a slewing bearing that is easy to adjust includes a placement table, a fixing platform fixedly installed on the top of the placement table, and an adjustment component provided at the bottom of the fixing platform.

[0008] The adjustment assembly includes an adjustment groove, a limiter, a support block, an adjustment slide, a limit slide, an adjustment block, an adjustment rod, and a push rod. The adjustment groove is located inside the table. The limiters are arranged in a circular array and fixedly connected to the bottom of the fixed platform. The support block is fixedly installed below the fixed platform. The adjustment slides are symmetrically distributed on the inner wall of the support block. The limit slide is located at the bottom of the adjustment groove. The adjustment block is slidably connected inside the limit slide. The adjustment rods are symmetrically distributed on the left and right and rotatably connected to the outer side of the adjustment rod. The push rod is fixedly connected to the front of the adjustment block.

[0009] Preferably, the end of the limiter away from the table is fixedly connected to the bottom of the adjustment groove, the adjustment block is located inside the support block, and the adjustment rod passes through the inside of the adjustment groove.

[0010] Preferably, a clamping assembly is provided on the top of the fixed platform. The clamping assembly includes a movable slide, a clamping block, and a sleeve rod. The movable slide is arranged in a circular array on the top of the fixed platform.

[0011] Preferably, the clamping block is slidably connected inside, the sleeve rod is rotatably connected to the bottom of the clamping block, and the clamping assembly also includes a rotary motor, a transmission disk and a transmission groove. The rotary motor is fixedly installed on the top of the fixed platform, and the transmission end of the rotary motor passes through the interior of the fixed platform.

[0012] Preferably, the transmission disc is fixedly installed on the transmission end of the rotary motor and located below the fixed platform. The transmission grooves are arranged in a circular array inside the transmission disc. The transmission disc is adapted to the sleeve rod, and the top of the clamping block is provided with a slot.

[0013] Preferably, a control panel is fixedly installed on the top of the table, support columns are fixedly connected in a rectangular array at the bottom of the table, anti-slip pads are fixedly connected to the bottom of the support columns, and heat dissipation grooves are provided on the front of the table.

[0014] This utility model has the following beneficial effects:

[0015] The adjustment mechanism allows operators to adjust the slewing bearing height after placing it on the fixed platform. Activating the push rod extends its telescopic end, pushing the adjusting block and causing it to slide within the limiting groove. Simultaneously, the adjusting rod slides within the groove. Because the groove slopes from high to low, the pressure on the support block decreases as the adjusting rod slides. Supported by the limit switch, the fixed platform can be raised. To lower the platform, simply retract the push rod, increasing the mounting distance between the adjusting rod and the support block. This simplifies height adjustment, improves operator convenience, and increases processing efficiency.

[0016] The clamping assembly is designed so that when the operator starts the rotary motor, it drives the transmission plate at its transmission end to rotate. As the transmission plate rotates, the arc-shaped transmission groove causes the clamping block to move inside the sliding groove. During this movement, the top slewing bearing is clamped and fixed. This not only effectively accommodates slewing bearings of different sizes, but also effectively prevents the slewing bearing from shaking during processing, thus effectively improving the safety of the slewing bearing.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Reference Figure 1-5 An adjustable slewing bearing machining fixing device includes a placement table 1, a fixing platform 2 fixedly installed on the top of the placement table 1, and an adjustment component 3 provided at the bottom of the fixing platform 2.

[0026] The adjustment assembly 3 includes an adjustment groove 301, a limiter 302, a support block 303, an adjustment slide 304, a limiting slide 305, an adjustment block 306, an adjustment rod 307, and a push rod 308. The adjustment groove 301 is opened inside the table 1. The limiter 302 is arranged in a ring array and fixedly connected to the bottom of the fixed platform 2. The support block 303 is fixedly installed below the fixed platform 2. The adjustment slide 304 is symmetrically distributed on the inner wall of the support block 303. The limiting slide 305 is opened at the bottom inside the adjustment groove 301. The adjustment block 306 is slidably connected inside the limiting slide 305. The adjustment rod 307 is symmetrically distributed on the left and right and rotatably connected to the outside of the adjustment rod 307. The push rod 308 is fixedly connected to the front of the adjustment block 306.

[0027] The end of the limiter 302 away from the table 1 is fixedly connected to the bottom of the adjustment groove 301. The adjustment block 306 is located inside the support block 303. The adjustment rod 307 passes through the interior of the adjustment slide 304. The end of the adjustment slide 304 near the push rod 308 is higher than the other end. The end of the push rod 308 away from the adjustment block 306 is fixedly connected to the inner wall of the adjustment groove 301. The adjustment assembly 3 is configured so that when the operator places the slewing bearing on the fixed platform 2, the push rod 308 can be activated to extend its telescopic end, pushing the adjustment block 306 and causing it to slide inside the limit groove 305. While sliding, the adjusting rod 307 slides inside the adjusting groove 304. Since the adjusting groove 304 is inclined from high to low, the pressure on the support block 303 is reduced when the adjusting rod 307 slides inside the adjusting groove 304. Then, with the support of the limiter 302, the position of the fixed platform 2 can be raised. When the position of the fixed platform 2 needs to be lowered, the telescopic end of the push rod 308 only needs to be retracted to increase the installation of the adjusting rod 307 on the support block 303, thereby realizing the lowering of the position of the fixed platform 2. This facilitates the adjustment of the height of the slewing bearing by the operator, effectively improves the convenience of the operator's processing operation, and improves the operator's processing efficiency.

[0028] Furthermore, a clamping assembly 4 is provided on the top of the fixed platform 2. The clamping assembly 4 includes a movable slide 401, a clamping block 402 and a sleeve rod 403. The movable slide 401 is arranged in a ring array on the top of the fixed platform 2.

[0029] The clamping block 402 is slidably connected inside, and the sleeve rod 403 is rotatably connected to the bottom of the clamping block 402. The clamping assembly 4 also includes a rotary motor 404, a transmission disk 405 and a transmission groove 406. The rotary motor 404 is fixedly installed on the top of the fixed platform 2, and the transmission end of the rotary motor 404 passes through the interior of the fixed platform 2.

[0030] The transmission disc 405 is fixedly installed at the transmission end of the rotary motor 404 and located below the fixed platform 2. The transmission groove 406 is arranged in a ring array inside the transmission disc 405. The transmission disc 405 is adapted to the sleeve rod 403. The top of the clamping block 402 is provided with a slot 5. The clamping block 402 is adapted to the moving slide 401. The sleeve rod 403 is located inside the transmission groove 406. The transmission groove 406 is arc-shaped. The support block 303 is rotatably connected to the transmission disc 405. With the clamping assembly set up, when the operator starts the rotary motor 404, it drives the transmission disc 405 at its transmission end to rotate. As the transmission disc 405 rotates, because the transmission groove 406 is arc-shaped, it will drive the clamping block 402 to move inside the moving slide 401. While moving, it clamps and fixes the top slewing bearing. This not only effectively adapts to slewing bearings of different sizes, but also effectively prevents the slewing bearing from shaking during processing, effectively improving the safety of the slewing bearing.

[0031] Furthermore, a control panel 6 is fixedly installed on the top of the table 1, and support columns 7 are fixedly connected in a rectangular array at the bottom of the table 1. Anti-slip pads 8 are fixedly connected to the bottom of the support columns 7. A heat dissipation groove 9 is provided on the front of the table 1. The control panel 6 is electrically connected to the rotary motor 404 and the push rod 308 respectively. The installation of the anti-slip pads 8 increases the friction with the placement surface, thereby improving the safety and stability of the placement.

[0032] In summary:

[0033] When in use, the operator first places the slewing bearing on the fixed platform 2, located on top of the clamping block 402. Then, the rotary motor 404 is started, which drives the transmission plate 405 at its transmission end to rotate. As the transmission plate 405 rotates, the transmission groove 406 is arc-shaped, which drives the clamping block 402 to move inside the moving slide 401. While moving, the top slewing bearing is clamped and fixed.

[0034] Furthermore, the operator can activate the push rod 308, extending its telescopic end to push the adjusting block 306, causing it to slide within the limiting groove 305. Simultaneously, the adjusting rod 307 slides within the adjusting groove 304. Since the adjusting groove 304 slopes from high to low, the pressure on the support block 303 is reduced as the adjusting rod 307 slides within it. Then, with the support of the limiter 302, the position of the fixed platform 2 can be raised. When the fixed platform 2 needs to be lowered, simply retract the telescopic end of the push rod 308, increasing the mounting of the adjusting rod 307 onto the support block 303, thus lowering the position of the fixed platform 2 and facilitating the operator's adjustment of the slewing bearing height.
