Description

Technical Field

[0001] This utility model relates to the field of bearing housing processing technology, specifically to an automatic clamping device for bearing housing lathes. Background Technology

[0002] As a core supporting component in a mechanical transmission system, the machining accuracy of bearing housings on a lathe directly determines the operational stability and service life of the equipment after subsequent assembly. The clamping process, as a key pre-processing step in the machining of bearing housings on a lathe, is responsible for the functions of workpiece positioning, fixing, and rapid pick-and-place. Its operational efficiency and reliability directly affect the overall production rhythm and processing quality.

[0003] The existing clamping operation requires manual placement of the bearing housing at the machining station, followed by adjustment of the clamping components to clamp it. After machining, the operation must be reversed to loosen the clamping components and remove the workpiece. In these processes, clamping a single workpiece often involves multiple steps, resulting in a cumbersome operation process and a long cycle time, which is difficult to adapt to the needs of efficient production.

[0004] Therefore, those skilled in the art have provided an automatic clamping device for bearing housing lathes to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide an automatic clamping device for bearing housing lathes to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An automatic clamping device for a bearing housing lathe includes a machining base. A clamping assembly is provided on the side surface of the machining base. The clamping assembly includes an arc-shaped notch on the side surface of the machining base. A fixed chuck is fixedly connected to the bottom of the machining base. A clamping groove is provided inside the fixed chuck. A cylinder is fixedly connected inside the clamping groove. A push rod is fixedly connected to the output end of the cylinder. A pressure plate is fixedly connected to the top of the push rod. A clamping elastic element is fixedly connected to the bottom of the pressure plate. An arc-shaped clamping plate is fixedly connected to the bottom of the clamping elastic element.

[0007] As a further embodiment of this utility model: the processing base has a placement groove inside, the bottom of the inner wall of the placement groove has a fitting groove, the bottom of the processing base is fixedly connected to a fixing block, and a reset elastic element is fixedly connected to one side of the fixing block.

[0008] As a further embodiment of this utility model: a limiting block is fixedly connected to one side of the reset elastic element, a fitting plate is movably connected inside the fitting groove, a limiting groove is opened inside the fitting plate, the limiting groove is adapted to the limiting block, a positioning pin is fixedly connected to the top of the fitting plate, and a bearing seat body is connected inside the placement groove.

[0009] As a further embodiment of this utility model: the outer wall of the cylinder is tightly fitted with the inner wall of the mounting groove, and the number of pressure plates is four and they are arranged in a circular array.

[0010] As a further embodiment of this utility model: the number of the compression elastic elements is four and they are arranged in a circular array, and the number of the arc-shaped clamps is four and they are arranged in a circular array.

[0011] As a further embodiment of this utility model: the number of limiting blocks is two and they are symmetrically distributed, the shape of the limiting blocks is L-shaped, and the number of limiting grooves is two and they are symmetrically distributed.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting up a clamping assembly, during use, the cylinder pushes out the push rod to move the arc-shaped clamping plate away from the processing base, facilitating the quick placement of the bearing seat; after placement, the cylinder retracts, and the push rod drives the arc-shaped clamping plate downward, which, together with the buffering effect of the clamping elastic element, avoids damaging the workpiece, and achieves stable clamping through rigid transmission. The entire process does not require repeated manual adjustment of the clamping components, which significantly simplifies the operation process, shortens the cycle time of clamping a single workpiece, and is more suitable for high-efficiency production needs.

[0013] 2. By combining a detachable mating plate with a positioning pin, and with the quick locking and unlocking of a limit block and a reset elastic element, it is possible to easily replace positioning pins of different specifications without adjusting the overall structure of the clamping device; and the reset elastic element drives the limit block to automatically engage with the limit groove, ensuring the positional stability of the positioning pin after replacement.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0022] Reference Figure 1 - Figure 3This embodiment provides an automatic clamping device for a bearing housing lathe, including a machining base 1. A clamping assembly 2 is provided on the side surface of the machining base 1. The clamping assembly 2 includes an arc-shaped notch 201 on the side surface of the machining base 1. A fixed chuck 202 is fixedly connected to the bottom of the machining base 1. A clamping groove 203 is provided inside the fixed chuck 202. A cylinder 204 is fixedly connected inside the clamping groove 203. A push rod 205 is fixedly connected to the output end of the cylinder 204. A pressure plate 206 is fixedly connected to the top of the push rod 205. A clamping elastic element 207, which can be a spring, is fixedly connected to the bottom of the pressure plate 206. An arc-shaped clamping plate 208 is fixedly connected to the bottom of the clamping elastic element 207. In use, the cylinder 204 pushes out the push rod 205, the pressure plate 206, and the clamping elastic element... Positioned away from the processing base 1, bearing housing body 11 is placed in the placement groove 3 of the processing base 1. The positioning hole at the bottom of the bearing housing is aligned with the positioning pin 10 and inserted to ensure the bearing housing is initially positioned circumferentially and radially. Then, the cylinder 204 is retracted by the reversing valve. The cylinder 204 drives the push rod 205 to move downward, which in turn drives the pressure plate 206, the clamping elastic element 207 and the arc-shaped clamp 208 to move downward as a whole. The arc-shaped clamp 208 first contacts the upper surface of the bearing housing body 11. At this time, the clamping elastic element 207 begins to compress, buffering the impact force at the moment of contact and avoiding damage to the surface of the bearing housing body 11. The cylinder 204 continues to retract, and the clamping elastic element 207 is compressed to its limit. The arc-shaped clamp 208 transmits the thrust of the cylinder 204 to the bearing housing body 11 through rigidity, achieving stable clamping. Example

[0023] Reference Figure 1 - Figure 6This embodiment is based on the previous embodiment, but differs in that the processing base 1 has a placement groove 3 inside, and a fitting groove 4 is formed at the bottom of the inner wall of the placement groove 3. A fixing block 5 is fixedly connected to the bottom of the processing base 1, and a reset elastic element 6 is fixedly connected to one side of the fixing block 5. The reset elastic element 6 can be a reset spring. A limit block 7 is fixedly connected to one side of the reset elastic element 6. A fitting plate 8 is movably connected inside the fitting groove 4. A limit groove 9 is formed inside the fitting plate 8, and the limit groove 9 is adapted to the limit block 7. A positioning pin 10 is fixedly connected to the top of the fitting plate 8. A bearing seat body 11 is connected inside the placement groove 3. The outer wall of the cylinder 204 is tightly fitted with the inner wall of the clamping groove 203. The number of pressure plates 206 is four and they are circular. The array is distributed as follows: four elastic elements 207 are arranged in a circular array; four arc-shaped clamping plates 208 are arranged in a circular array; two limiting blocks 7 are arranged symmetrically; the limiting blocks 7 are L-shaped; and two limiting grooves 9 are arranged symmetrically. When different specifications of bearing housing bodies 11 need to be processed, the limiting blocks 7 are manually pressed to disengage from the limiting grooves 9, thus releasing the locking of the mating plate 8. Then, the mating plate 8 is pulled out from the mating groove 4 to complete the disassembly of the old positioning pin 10. The corresponding specification of positioning pin 10 is selected, and the mating plate 8 at the bottom of the positioning pin 10 is inserted into the mating groove 4. The limiting blocks 7 are released, and the reset elastic element 6 pushes the limiting blocks 7 to re-engage into the limiting groove 9 of the new mating plate 8, thus completing the replacement of the positioning pin 10.
