Description

Technical Field

[0001] This utility model relates to the field of bearing housing technology, specifically a jig for processing bearing housings. Background Technology

[0002] A bearing housing is a component used to support and position bearings. It is typically made of metal (such as cast iron or steel) or engineering plastics. It provides a stable mounting base for the bearing, ensuring it maintains the correct position and orientation during operation. Bearing housings are indispensable components in mechanical equipment. By providing stable support and precise positioning, they ensure the normal operation of the bearing, thereby improving the performance and lifespan of the entire equipment. A bearing housing machining fixture is a specially designed jig used to provide stable support and precise positioning during bearing housing machining. It ensures the bearing housing maintains the correct position and orientation during processing, thus improving machining accuracy and efficiency.

[0003] After the bearing housing is machined, there may be residual debris on the surface, especially during the grinding process, such as turning, milling, drilling, and grinding. Metal debris can easily adhere to the surface of the bearing housing. Currently, the fixture and cleaning mechanism are controlled by two sets of drive equipment. When cleaning the machined bearing housing, the staff needs to manually operate the cleaning mechanism, which not only reduces the processing efficiency, but also increases the cleaning cost due to the independently controlled cleaning mechanism. Utility Model Content

[0004] The purpose of this utility model is to provide a jig for processing bearing housings, which has the advantages of simultaneously driving the air jet plate to clean the surface of the bearing housing while moving the clamping plate to loosen the bearing housing, thereby reducing cleaning costs and improving processing efficiency. It solves the problems of high cost and low processing efficiency of jigs for cleaning bearing housings.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a jig for machining bearing seats, comprising a housing and threaded sleeves. Lead screws are movably mounted on both sides of the housing. A fixing block is installed inside the housing at one end of each of the two lead screws. The two threaded sleeves are meshed with the two lead screws. A one-way gear is mounted on the lead screw on the left side of the housing. A fixing rod is movably mounted on the side of the housing in front of the one-way gear. A gear plate is mounted at one end of the fixing rod. A pump body is mounted on the front side of the housing. A drive shaft is movably mounted on the pump body. An air intake pipe is mounted at the bottom of the pump body. An air outlet pipe is mounted at the top of the pump body. A universal joint is mounted at the top of the air outlet pipe. An air jet plate is mounted at the end of the universal joint facing away from the pump body.

[0006] Preferably, a servo motor is installed on the right side of the housing. The servo motor transmission structure is fixedly connected to a lead screw on one side of the housing. The opposite ends of the two lead screws are movably connected to a fixed block, and the opposite ends of the two lead screws are fixedly connected.

[0007] Preferably, the outer threads of the two lead screws are distributed in opposite directions.

[0008] Preferably, both of the threaded sleeves are fitted with clamps at their tops.

[0009] Preferably, each of the two threaded sleeves is equipped with a slider on its front side, and two sliding grooves are symmetrically opened on the front side inside the housing, with the two sliders and the two sliding grooves being slidably connected.

[0010] Preferably, the one-way gear and the toothed disc are meshed together, the fixed rod is movably connected to the drive shaft via a belt, and the drive shaft extends into the pump body and has turbine blades installed in a ring array on its outer side.

[0011] Preferably, a collection tray is inserted into the housing below the fixing block from the rear, and a filter screen is installed at the bottom of the collection tray.

[0012] Preferably, a support frame is welded to the bottom of the housing, and the bottom of the support frame has fixing holes arranged in a rectangular array.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention utilizes a one-way gear and an air jet plate. After the bearing housing is machined, a servo motor drives two lead screws to rotate in opposite directions, separating the two clamping plates from the bearing housing. Simultaneously, the lead screws drive the one-way gear to rotate, which in turn drives a fixed rod to rotate via a gear plate. The fixed rod, in turn, drives a drive shaft via a belt, which in turn drives a turbine blade inside the pump body. The turbine blade generates centrifugal force during rotation. Under this centrifugal force, the pump body draws in air through the suction pipe and then delivers the air to a universal joint through the exhaust pipe. The universal joint is used to adjust the air jet plate to face the bearing housing. The universal joint then blows a high-speed airflow onto the surface of the bearing housing through the air jet plate, blowing debris downwards. The air mixed with debris enters a collection drawer, where a filter at the bottom intercepts the debris. This achieves the effect of simultaneously driving the air jet plate to clean the bearing housing surface while the clamping plates move to loosen the bearing housing, reducing cleaning costs and improving processing efficiency.

[0024] Example 1

[0025] like Figures 1-4As shown, this utility model proposes a jig for machining bearing housings, including a housing 3 and a threaded sleeve 7. Lead screws 6 are movably mounted on both sides of the housing 3. A fixing block 5 is installed inside the housing 3 at one opposite end of the two lead screws 6. A servo motor 17 is mounted on the right side of the housing 3. The transmission structure of the servo motor 17 is fixedly connected to the lead screw 6 on one side of the housing 3. The opposite ends of the two lead screws 6 are movably connected to the fixing block 5. The servo motor 17 drives the lead screw 6 on the right side of the housing 3 to rotate through the transmission structure. The two lead screws 6 rotate synchronously. The fixing block 5 increases the stability of the two lead screws 6, and simultaneously provides bearing housing support. The bearing seat provides support. Two threaded sleeves 7 are engaged with two lead screws 6. The outer threads of the two lead screws 6 are distributed in opposite directions. The two threaded sleeves 7 can move in opposite or relative directions between the two rotating lead screws 6. Each of the two threaded sleeves 7 has a clamping plate 8 installed on its top. During the movement of the two threaded sleeves 7, the two clamping plates 8 will move. The relative movement of the two threaded sleeves 7 and the two clamping plates 8 can clamp and fix the bearing seat. A one-way gear 18 is installed on the lead screw 6 on the left side of the housing 3. A fixing rod 22 is movably installed on the side of the housing 3 in front of the one-way gear 18. A gear plate 19 is installed at one end of the fixing rod 22. The one-way gear 18 and the gear plate 19 mesh. The screw 6 rotates in the opposite direction, driving the one-way gear 18 to rotate. The one-way gear 18 drives the fixed rod 22 to rotate via the gear plate 19. A pump body 14 is installed on the front side of the housing 3. A drive shaft 10 is movably installed on the pump body 14. The fixed rod 22 is movably connected to the drive shaft 10 via a belt 9. A section of the drive shaft 10 extends into the pump body 14, and turbine blades are installed in a ring array on its outer side. When the fixed rod 22 rotates, it drives the drive shaft 10 to rotate via the belt 9. The drive shaft 10 drives the turbine blades inside the pump body 14 to rotate. The turbine blades generate centrifugal force when rotating. An air intake pipe 20 is installed at the bottom of the pump body 14. 4. An air outlet pipe 13 is installed at the top, and a universal tube 12 is installed at the top of the air outlet pipe 13. An air jet plate 11 is installed at the end of the universal tube 12 away from the pump body 14. A collection drawer 4 is inserted into the housing 3 below the fixing block 5 from the rear. A filter screen 21 is installed at the bottom of the collection drawer 4. The downward-flowing air will pass through the collection drawer 4. The filter screen 21 at the bottom of the collection drawer 4 intercepts the debris in the air. A support frame 1 is welded to the bottom of the housing 3. The bottom of the support frame 1 has a rectangular array of fixing holes 2. Through the fixing holes 2 of the support frame 1, the support frame 1 can be fixed to the ground or a load-bearing structure using bolts and other tools. The support frame 1 provides support for the housing 3.

[0026] Example 2

[0027] like Figures 1-4As shown, the present invention proposes a bearing housing processing fixture, which, compared with the first embodiment, further includes: a sliding groove 15 and a slider 16. A slider 16 is installed on the front side of each of the two threaded sleeves 7. Two sliding grooves 15 are symmetrically opened on the front side of the inside of the housing 3. The two sliders 16 and the two sliding grooves 15 are slidably connected. The two sliders 16 limit the two threaded sleeves 7. During the movement of the two threaded sleeves 7, the two sliders 16 slide in the two sliding grooves 15 to prevent the two threaded sleeves 7 from shaking.

[0028] Working principle: The bearing seat to be fixed is placed on top of the fixing block 5. The servo motor 17 drives the two lead screws 6 inside the housing 3 to rotate in the forward direction through the transmission structure. The two threaded sleeves 7 move on the two rotating lead screws 6, and the two threaded sleeves 7 drive the two clamping plates 8 to move in opposite directions. The two clamping plates 8 clamp and fix the bearing seat on top of the fixing block 5. After the bearing seat is processed, the servo motor 17 drives the two lead screws 6 to rotate in the reverse direction. The two threaded sleeves 7 drive the two clamping plates 8 to move in opposite directions, so that the two clamping plates 8 separate from the bearing seat. At the same time, the lead screws 6 drive the one-way gear 18 to rotate. The one-way gear 18 drives the fixing rod through the gear plate 19. 22 rotates, and the fixed rod 22 drives the drive shaft 10 to rotate via the belt 9. The drive shaft 10 drives the turbine blades inside the pump body 14 to rotate. When the turbine blades rotate, they generate centrifugal force. Under the influence of centrifugal force, the pump body 14 draws in air through the suction pipe 20 and then delivers the air to the universal pipe 12 through the exhaust pipe 13. The universal pipe 12 is used to adjust the position of the jet plate 11 to face the bearing seat. The universal pipe 12 blows the high-speed airflow toward the surface of the bearing seat through the jet plate 11, blowing the debris on the surface of the bearing seat downward. The air mixed with the debris enters the collection tray 4, and the filter screen 21 at the bottom of the collection tray 4 intercepts the debris in the air.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
