Technical Field
[0001] This utility model relates to the technical field of engine component processing equipment, and in particular to a surface grinding device for engine volute subassemblies. Background Technology
[0002] In engine manufacturing, the volute subassembly is a critical component, and its surface quality directly affects engine performance. Under current technology, manual grinding is difficult to control in terms of precision and is inefficient. Traditional mechanical grinding equipment is poorly adaptable to the complex curved surfaces of the volute, making it difficult to ensure comprehensive and uniform grinding, resulting in substandard surface roughness and affecting engine stability and reliability. Existing grinding equipment also struggles to meet the specific requirements of grinding the engine volute subassembly surface. Ordinary grinding and polishing machines may generate significant vibrations during grinding, which is detrimental to grinding the high-precision volute reference surface, affecting the smoothness and finish of the grinding. Therefore, on the one hand, it is necessary to improve grinding precision and efficiency to meet the demands of large-scale production; on the other hand, it is essential to achieve automation and intelligence to reduce manual intervention and improve product quality stability.
[0003] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: the height of the grinding machine body is too high, making it unable to grind engine parts. Grinding engine parts usually requires precise operation on specific parts. The excessive height of the grinding machine body makes it impossible for the grinding tools to accurately contact the surface of the engine parts to be ground, resulting in the inability to grind the parts according to the process requirements. Therefore, an engine volute sub-assembly surface grinding device is proposed to address the above problems. Utility Model Content
[0004] The purpose of this utility model is to solve the problem that the height of the existing grinding machine body is too high, making it unable to grind engine parts. Grinding engine parts usually requires precise operation on specific parts. The excessive height of the grinding machine body makes it impossible for the grinding tools to accurately contact the surface of the engine parts to be ground, resulting in the inability to grind the parts according to the process requirements. Therefore, the proposed engine volute sub-assembly surface grinding device is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an engine volute sub-assembly surface grinding device, including a base, an adjustment device on the surface of the base, the adjustment device including two fixed plates, the two fixed plates being fixedly connected to the surface of the base, a fixed rod being fixedly connected to one side of the two fixed plates that are close to each other, a rotating plate being rotatably connected to the arc surface of the fixed rod, two clamping plates being fixedly connected to the surface of the base, a round rod being fixedly connected to one side of the two clamping plates that are close to each other, an elliptical plate being rotatably connected to the arc surface of the round rod, a grinding machine body being fixedly connected to one side of the rotating plate, a U-shaped frame being fixedly connected to the arc surface of the grinding machine body, a setting rod being fixedly connected to the inner surface of the U-shaped frame, a limit rod being rotatably connected to the arc surface of the setting rod, a plurality of limit grooves being opened on the arc surface of the limit rod, an H-shaped frame being fixedly connected to the surface of the base, a drive frame being fixedly connected to the surface of the H-shaped frame, a hollow plate being slidably connected to the inner surface of the drive frame, a rotating shaft being installed inside the grinding machine body, and a grinding disc being slidably connected to the arc surface of the rotating shaft.
[0006] The effect achieved by the above-mentioned components is as follows: by setting the adjustment device, the height of the grinding machine body can be adjusted, avoiding the situation where the grinding machine body is too high and cannot grind engine parts. Grinding engine parts usually requires precise operation on specific parts. If the grinding machine body is too high, the grinding tools cannot accurately contact the surface of the engine parts to be ground, resulting in the parts not being ground according to the process requirements, the product failing to meet quality standards, and increasing production costs.
[0007] Preferably, a spring is fixedly connected to the inner surface of the hollow plate, and the other end of the spring is fixedly connected to the surface of the drive frame.
[0008] The effect achieved by the above components is that the spring pulls the hollow plate to slide within the drive frame, making the hollow plate more stable on the inner surface of the limiting groove.
[0009] Preferably, the arc surface of the fixing rod is fitted with two torsion springs, and the two ends of the torsion springs are fixedly connected to the other side of the fixing plate and the one side of the rotating plate, respectively.
[0010] The effect achieved by the above components is that the torque of the torsion spring automatically rotates the grinder body, causing the grinder body to rotate back to its original position.
[0011] Preferably, the arc surface of the rotating shaft is provided with a clamping device, the clamping device includes a base plate, the base plate is slidably connected to the arc surface of the rotating shaft, a grinding disc is slidably connected to the arc surface of the rotating shaft, a ring is slidably connected to the arc surface of the rotating shaft, two placement holes are opened on one side of the ring, and a threaded rod is inserted into the internal thread of the rotating shaft.
[0012] The effect achieved by the above-mentioned components is as follows: by setting up a clamping device, the grinding disc is clamped, avoiding the grinding disc from shaking and affecting the grinding of engine parts. The shaking of the grinding disc will cause uneven contact on the surface of engine parts, some areas will be over-grinded and some areas will be under-grinded, and the grinding position will be deviated. It is difficult to ensure the precise grinding size and shape, resulting in increased surface roughness and failure to meet the expected smoothness requirements, thus affecting the performance of the engine.
[0013] Preferably, the arc surface of the rotating shaft is slidably connected with an anti-slip pad, and one side of the anti-slip pad abuts against one side of the ring.
[0014] The effect achieved by the above components is that the anti-slip pad presses against the grinding disc, further preventing the grinding disc from shaking.
[0015] Preferably, the inner surface of the placement hole is slidably connected to a mounting rod, and one end of the two mounting rods is fixedly connected to a mounting bracket.
[0016] The effect achieved by the above components is that when it is necessary to clamp the grinding disc, rotating the mounting rod will drive the ring to squeeze the grinding disc, which facilitates the operation of the staff.

[0026] Reference Figure 1 As shown, this utility model provides a technical solution: an engine volute sub-assembly surface grinding device, including a base 1. The surface of the base 1 is provided with an adjustment device 4. By setting the adjustment device 4, the height of the grinding machine body 2 can be adjusted, avoiding the situation where the grinding machine body 2 is too high, preventing it from grinding engine parts. Grinding engine parts usually requires precise operation on specific areas. If the grinding machine body 2 is too high, the grinding tool cannot accurately contact the surface of the engine part to be ground, resulting in the inability to grind the parts according to process requirements, causing the product to fail to meet quality standards and increasing production costs. The arc surface of the rotating shaft 3 is provided with a clamping device 5. By setting the clamping device 5, the grinding disc 52 is clamped, preventing the grinding disc 52 from shaking and affecting the grinding of engine parts. Shaking of the grinding disc 52 will cause uneven contact on the surface of the engine parts, resulting in over-grinding in some areas and under-grinding in others, causing deviations in the grinding position, making it difficult to guarantee precise grinding dimensions and shapes, leading to increased surface roughness, failure to meet the expected smoothness requirements, and affecting engine performance.
[0027] The specific settings and functions of the adjustment device 4 and the clamping device 5 will be explained in detail below.
[0028] Reference Figure 2 and Figure 3As shown, in this embodiment: the adjusting device 4 includes two fixing plates 401, which are fixedly connected to the surface of the base 1. A fixing rod 402 is fixedly connected to one side of the two fixing plates 401 that is close to each other. A rotating plate 403 is rotatably connected to the arc surface of the fixing rod 402. Two clamping plates 404 are fixedly connected to the surface of the base 1. A round rod 405 is fixedly connected to one side of the two clamping plates 404 that is close to each other. An elliptical plate 406 is rotatably connected to the arc surface of the round rod 405. A grinding machine body 2 is fixedly connected to one side of the rotating plate 403. A U-shaped frame 407 is fixedly connected to the arc surface of the mill body 2. A setting rod 408 is fixedly connected to the inner surface of the U-shaped frame 407. A limiting rod 409 is rotatably connected to the arc surface of the setting rod 408. Several limiting grooves 410 are opened on the arc surface of the limiting rod 409. An H-shaped frame 411 is fixedly connected to the surface of the base 1. A drive frame 412 is fixedly connected to the surface of the H-shaped frame 411. A hollow plate 413 is slidably connected to the inner surface of the drive frame 412. A rotating shaft 3 is installed inside the mill body 2. A grinding disc 52 is slidably connected to the arc surface of the rotating shaft 3. A spring 414 is fixedly connected to the inner surface of the hollow plate 413. The other end of the spring 414 is fixedly connected to the surface of the drive frame 412. The spring 414 pulls the hollow plate 413 to slide within the drive frame 412, making the hollow plate 413 more stable on the inner surface of the limiting grooves 410. Two torsion springs 415 are fitted on the arc surface of the fixed rod 402. The two ends of the torsion springs 415 are fixedly connected to the other side of the fixed plate 401 and one side of the rotating plate 403, respectively. The torque of the torsion springs 415 automatically rotates the grinder body 2, causing the grinder body 2 to rotate back to its original position.
[0029] Reference Figure 4 and Figure 5 As shown, specifically, the clamping device 5 includes a base plate 51, which is slidably connected to the arc surface of the rotating shaft 3. A grinding disc 52 is slidably connected to the arc surface of the rotating shaft 3, and a ring 53 is also slidably connected to the arc surface of the rotating shaft 3. Two placement holes 54 are provided on one side of the ring 53, and a threaded rod 55 is threaded into the rotating shaft 3. An anti-slip pad 56 is slidably connected to the arc surface of the rotating shaft 3, with one side of the anti-slip pad 56 abutting against one side of the ring 53. The anti-slip pad 56 presses against the grinding disc 52, further preventing the grinding disc 52 from shaking. Mounting rods 57 are slidably connected to the inner surface of the placement holes 54, and mounting brackets 58 are fixedly connected to one end of each mounting rod 57. When it is necessary to clamp the grinding disc 52, rotating the mounting rods 57 causes the ring 53 to press against the grinding disc 52, facilitating operation by the operator.
[0030] Working principle: When the operator needs to adjust the height of the grinder body 2 using the adjustment device 4, firstly, the hollow plate 413 is pulled to slide on the inner surface of the drive frame 412, causing the spring 414 to be stretched. Under the support of the H-shaped frame 411, when the surface of the hollow plate 413 disengages from the limiting groove 410 on the surface of the limiting rod 409, the limiting rod 409 is pulled to slide on the inner surface of the H-shaped frame 411. Under the support of the U-shaped frame 407, the limiting rod 409 rotates on the arc surface of the setting rod 408. When the grinder body 2 starts to rotate, the fixed plate 4... Supported by 01, the rotating plate 403 initially rotates around the arc surface of the fixed rod 402. Supported by the clamping plate 404, the elliptical plate 406 initially rotates around the arc surface of the round rod 405, thereby driving the torsion spring 415 to be compressed. When the grinder body 2 is adjusted to a suitable height, the hollow plate 413 is released and slides on the inner surface of the drive frame 412. The spring 414 rebounds. Supported by the H-shaped frame 411, the surface of the hollow plate 413 enters the limiting groove 410 on the surface of the limiting rod 409, limiting the limiting rod 409, thereby limiting the height of the grinder body 2.
[0031] When the operator needs to use the clamping device 5 to clamp the grinding disc 52, firstly, slide the base plate 51 along the arc surface of the rotating shaft 3. When the base plate 51 reaches the lowest point of the rotating shaft 3, slide the grinding disc 52 along the arc surface of the rotating shaft 3. When the grinding disc 52 abuts against the base plate 51, then slide the anti-slip pad 56 along the arc surface of the rotating shaft 3, and the anti-slip pad 56 abuts against the grinding disc 52. Then rotate the ring 53 along the arc surface of the rotating shaft 3. When it cannot be rotated by hand... Place one end of each of the two mounting rods 57 into the inner surface of the placement hole 54 to the bottom. Rotate the threaded rod 55 on the inner surface of the mounting bracket 58. When the surface of the threaded rod 55 enters the rotating shaft 3, rotate the mounting bracket 58, which will drive the two mounting rods 57 and the ring 53 to rotate. The two mounting rods 57, the anti-slip pad 56, the grinding disc 52 and the base plate 51 will press against each other and clamp the grinding disc 52. When the grinding disc 52 is tightly pressed, the engine parts will be ground.
