Description

Technical Field

[0001] This invention belongs to the field of compressor assembly technology, specifically a compressor component press-fitting and positioning device. Background Technology

[0002] A compressor is a mechanical device that converts energy and transports fluids by compressing a medium. It is widely used in refrigeration, HVAC, power machinery and other fields. The assembly accuracy of its internal components directly affects the stability and service life of the whole machine. During the compressor assembly process, bearings, bushings, housings and other components need to be press-fitted and positioned to ensure the coaxiality and relative position of each part are accurate. Therefore, a special press-fitting and positioning device is required to achieve precise assembly operations.

[0003] Existing compressor component press-fitting and positioning devices mostly use multiple bolts to directly fasten the positioning seat to the equipment base. The positioning seat and the main body of the equipment are rigidly fixed. When replacing positioning seats of different specifications, multiple sets of bolts need to be disassembled and reassembled one by one. The operation steps are cumbersome and the replacement efficiency is low. This seriously affects the press-fitting and assembly efficiency of various compressor components and cannot meet the production needs of rapid production changeover. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a compressor component press-fit positioning device, which effectively solves the problem of the inconvenience of quickly replacing the positioning seat.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a compressor component press-fitting and positioning device, comprising a base, a positioning seat on the top of the base, a press head directly above the positioning seat, a fixing mechanism on the top of the base, and a buffer mechanism and a limiting mechanism on the fixing mechanism;

[0006] The fixing mechanism includes a U-shaped round rod fixed to the top of the base. Two slide rods are symmetrically fixedly connected between the U-shaped round rod and the base. Slide plates are movably sleeved on the outer side of each slide rod. Support wheels located on the top of the base are provided at the bottom of each slide plate. Side cylinders are fixedly connected to the outer side of each slide plate. Limiting rods are movably sleeved inside each side cylinder. Two positioning blocks are symmetrically fixedly connected to the outer side of the positioning seat. Each positioning block is provided with a limiting hole. The two limiting rods correspond to the two limiting holes respectively, and the outer diameter of each limiting rod is equal to the inner diameter of each limiting hole.

[0007] Preferably, a guide rod is fixedly connected to the bottom of the base, and two guide plates are symmetrically and movably sleeved on the outer side of the guide rod. A positioning post is fixedly connected to the top of each of the two guide plates, and two positioning blocks are movably sleeved on the outer side of the two positioning posts. Two guide grooves are symmetrically provided on the base, and the two guide plates are slidably connected to the two guide grooves respectively.

[0008] Preferably, a sleeve rod is fixedly connected to the top of the guide plate, and a limiting rod passes through the sleeve rod.

[0009] Preferably, a base plate is fixedly sleeved on the outer middle of the guide rod, the base plate is fixed to the bottom of the base, a drive motor is fixedly installed on the bottom of the base plate, a drive shaft is fixedly connected to the drive motor, and a chassis located between two guide plates is fixedly connected to the bottom of the drive shaft. Two drive rods are rotatably connected to the bottom of the chassis at equal angles, and the ends of the two drive rods away from the chassis are rotatably connected to the bottom of the two guide plates respectively.

[0010] Preferably, a lifting plate is movably sleeved on the outer side of the U-shaped rod, a pressure head is installed at the bottom of the lifting plate, and L-shaped plates are fixedly connected to both sides of the bottom of the lifting plate. Both L-shaped plates are movably sleeved on the outer side of the U-shaped rod, and movable rods are rotatably connected to the bottom of both L-shaped plates. The bottom ends of the two movable rods are rotatably connected to the top of the two sliding plates, respectively.

[0011] Preferably, a column is fixedly connected to the top of the lifting plate, a top plate is fixedly connected to the top of the column, a bracket is fixedly sleeved on the middle of the outer side of the U-shaped rod, the bracket is fixed to the top of the base, a hydraulic cylinder is fixedly installed on the bracket, and the top of the top plate is fixed to the output end of the hydraulic cylinder.

[0012] Preferably, the buffer mechanism includes a movable frame movably sleeved on the outside of the column, a buffer spring fixedly connected between the movable frame and the top of the lifting plate, the buffer spring being sleeved on the outside of the column, the movable frame passing through the lifting plate and movably connected to the lifting plate, and the pressure head being fixed to the bottom of the movable frame.

[0013] Preferably, the limiting mechanism includes a lifting frame that is movably sleeved on the outside of the bracket. Connecting columns are fixedly connected to both sides of the lifting frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention enables the lifting plate to rise and fall by activating the hydraulic cylinder, facilitating the removal of the two limit rods through or from the two limit holes, allowing for quick disassembly and replacement of the positioning seat. Furthermore, activating the drive motor enables the two guide plates to move, facilitating the adjustment of the distance between the two positioning columns, thereby facilitating the installation of positioning seats of different specifications.

[0017] 2. This invention can drive the lifting plate downward by activating the hydraulic cylinder, which facilitates the descent of the pressure head to squeeze the parts. It can also cause the buffer spring to deform, which allows the buffer spring to buffer the impact force through deformation, thereby preventing rigid impact and improving the pressing effect.

[0018] 3. This invention allows the lifting frame to slide along the bracket and be fixed to the bracket by tightening bolts, which facilitates the fixing of the two limit rings after they have moved. This makes it easy to adjust the height of the two limit rings to limit the lifting plate and restrict the downward distance of the pressure head to prevent parts from being crushed.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] Example 1, by Figures 1-6 The present invention relates to a compressor component press-fitting and positioning device, comprising a base 1, a positioning seat 5 on the top of the base 1 for placing the component for precise positioning, a pressure head 6 directly above the positioning seat 5, a fixing mechanism 2 on the top of the base 1, and a buffer mechanism 3 and a limiting mechanism 4 on the fixing mechanism 2.

[0030] In Embodiment 2, based on Embodiment 1, the fixing mechanism 2 includes a U-shaped rod 201 fixed to the top of the base 1. Two sliding rods 2014 are symmetrically fixedly connected between the U-shaped rod 201 and the base 1. Slide plates 206 are movably sleeved on the outer sides of each of the two sliding rods 2014. Support wheels 2015 are located at the bottom of each of the two slide plates 206 and are positioned on the top of the base 1. The support wheels 2015 support the slide plates 206, ensuring their stability when sliding on the sliding rods 2014. Side cylinders 2016 are fixedly connected to the outer sides of each of the two slide plates 206. Limiting rods 2017 are movably sleeved inside each of the two side cylinders 2016. Two positioning blocks 208 are symmetrically fixedly connected to the outer sides of the positioning seat 5. Each of the two positioning blocks 208 has a limiting hole 2020, and two limiting rods 2017 correspond to the two limiting holes 2020 respectively. The outer diameter of each limiting rod 2017 is equal to the inner diameter of each limiting hole 2020. A guide rod 2021 is fixedly connected to the bottom of the base 1. Two guide plates 207 are symmetrically and movably sleeved on the outer side of the guide rod 2021. Positioning posts 2019 are fixedly connected to the top of each guide plate 207. The two positioning blocks 208 are movably sleeved on the outer side of the two positioning posts 2019 respectively. Two guide grooves 7 are symmetrically provided on the base 1. The two guide plates 207 are slidably connected to the two guide grooves 7 respectively. A sleeve rod 2018 is fixedly connected to the top of the guide plate 207. The limiting rod 2017 passes through the sleeve rod 2018. A base plate 2022 is fixedly sleeved on the outer middle of the guide rod 2021. The base plate 2022 is fixed to the bottom of the base 1. A drive motor 2023 is fixedly installed on the bottom of the base plate 2022. A drive shaft 2024 is fixedly connected to the drive motor 2023. A chassis 209 located between two guide plates 207 is fixedly connected to the bottom of the drive shaft 2024. Two drive rods 2010 are rotatably connected at equal angles to the bottom of the chassis 209. The ends of the two drive rods 2010 away from the chassis 209 are rotatably connected to the bottom of the two guide plates 207 respectively. A lifting plate 203 is movably sleeved on the outer side of the U-shaped rod 201. A pressure head 6 is installed on the lifting plate 203. At the bottom of 03, L-shaped plates 204 are fixedly connected to both sides of the bottom of the lifting plate 203. The two L-shaped plates 204 are movably sleeved on the outside of the U-shaped round rod 201. The bottom of the two L-shaped plates 204 is rotatably connected to the movable rod 205. The bottom ends of the two movable rods 205 are rotatably connected to the top of the two sliding plates 206 respectively. The top of the lifting plate 203 is fixedly connected to the column 2011. The top of the column 2011 is fixedly connected to the top plate 2012. The middle of the outside of the U-shaped round rod 201 is fixedly sleeved to the bracket 2013. The bracket 2013 is fixed to the top of the base 1. A hydraulic cylinder 202 is fixedly installed on the bracket 2013. The top of the top plate 2012 is fixed to the output end of the hydraulic cylinder 202.

[0031] First, place the positioning seat 5 on top of the base 1, so that the two positioning blocks 208 are respectively fitted onto the outside of the two positioning columns 2019. Then, start the hydraulic cylinder 202, which drives the lifting plate 203 to slide down along the U-shaped rod 201 through the top plate 2012 and the column 2011, and drives the two L-shaped plates 204 to slide down along the U-shaped rod 201. Then, the two movable rods 205 drive the two sliding plates 206 to slide along the two sliding rods 2014 respectively. At the same time, the two side cylinders 2016 and the two limiting rods 2017 move until the two limiting rods 2017 pass through the two limiting holes 2020 respectively, thereby limiting the two positioning blocks 208 and completing the installation and fixing of the positioning seat 5. When the lifting plate 203 continues to descend, the two limiting rods 2017 continue to move, and at the same time, the pressure head 6 descends to press the parts.

[0032] When the hydraulic cylinder 202 is activated to raise the lifting plate 203, it drives the two limit rods 2017 to move away from each other, causing the two limit rods 2017 to disengage from the two limit holes 2020 respectively, releasing the limiting effect on the two positioning blocks 208, realizing the disassembly of the positioning seat 5, so that the positioning seat 5 can be quickly replaced.

[0033] When the drive motor 2023 is started, it drives the drive shaft 2024 to rotate, which in turn drives the chassis 209 to rotate. The two drive rods 2010 drive the two guide plates 207 to slide along the guide rods 2021. At the same time, the two guide plates 207 slide along the two guide grooves 7, changing the position of the two positioning posts 2019. Simultaneously, the two sleeve rods 2018 drive the two limit rods 2017 to move at the same time, so that the two positioning blocks 208 on the positioning seats 5 of different specifications can be respectively fitted onto the outside of the two positioning posts 2019. Finally, the positioning seats 5 of different specifications are installed and fixed.

[0034] In embodiment three, based on embodiment one, the buffer mechanism 3 includes a movable frame 301 that is movably sleeved on the outside of the column 2011, a buffer spring 302 that is fixedly connected between the movable frame 301 and the top of the lifting plate 203, the buffer spring 302 being sleeved on the outside of the column 2011, the movable frame 301 passing through the lifting plate 203 and being movably connected to the lifting plate 203, and the pressure head 6 being fixed to the bottom of the movable frame 301;

[0035] When the hydraulic cylinder 202 is activated, it drives the lifting plate 203 to move downward, causing the pressure head 6 to descend. When the pressure head 6 presses against the parts, it drives the movable frame 301 to slide along the column 2011. At this time, the buffer spring 302 deforms, and the buffer spring 302 buffers the impact force through deformation, thus preventing rigid impact and improving the pressing effect.

[0036] In Example 4, based on Example 1, the limiting mechanism 4 includes a lifting frame 401 movably sleeved on the outside of the bracket 2013. Both sides of the lifting frame 401 are fixedly connected to connecting columns 404. The ends of the two connecting columns 404 away from the lifting frame 401 are fixedly connected to limiting rings 405. The two limiting rings 405 are movably sleeved on the outside of the U-shaped round rod 201, and the two limiting rings 405 are located below the lifting plate 203. A bolt 403 is installed between the lifting frame 401 and the bracket 2013. The bracket 2013 is provided with a plurality of screw holes 402 that match the bolt 403. One end of the bolt 403 is screwed into the corresponding screw hole 402.

[0037] First, slide the lifting frame 401 along the bracket 2013. Then, through the two connecting columns 404, drive the two limiting rings 405 to slide along the U-shaped rod 201. Next, tighten the bolts 403 so that they are screwed into the corresponding screw holes 402, and fix the lifting frame 401 to the bracket 2013. This achieves the fixation of the two limiting rings 405 after they have moved, thereby adjusting the height of the two limiting rings 405 to limit the lifting plate 203. Finally, limit the downward distance of the pressure head 6 to prevent the parts from being crushed.
