Description

Technical Field

[0001] This utility model relates to the field of compressor screw processing technology, specifically a clamping device for compressor screw processing. Background Technology

[0002] As a core component of the compressor, the compressor screw's manufacturing process is extremely crucial. First, carefully selected high-quality raw materials, such as special alloy steel, are essential to ensure the screw possesses excellent strength and wear resistance. Next, using high-precision CNC machining equipment, the screw undergoes multiple processes including turning, milling, and grinding, based on meticulously designed drawings. Turning initially shapes the screw's outer contour, milling carves precise helical grooves, and grinding performs fine surface finishing, significantly improving surface smoothness and dimensional accuracy.

[0003] Existing clamping and conveying devices are ill-suited to the unique dimensions and structure of long screws, failing to provide stable support for both ends of the screw during processing. This leads to screw wobbling and displacement during grinding, hindering uniform grinding, severely impacting grinding accuracy and efficiency, increasing the reject rate, and impeding the efficient and high-quality development of the compressor screw processing industry. Therefore, improvements are necessary. Utility Model Content

[0008] Preferably, two semicircular mounting bases are provided on the left side of the mounting housing, with the two semicircular mounting bases arranged opposite each other inside the mounting housing.

[0009] Preferably, two said semicircle mounting seats are provided with rollers inside the semicircle mounting seats.

[0010] Preferably, the mounting shell is provided with through holes on the front and rear sides, and the movable rod is slidably connected to the through holes.

[0011] Preferably, the mounting shell is provided with mounting barrels fixedly connected to the through holes on the front and rear sides, and the limiting block has a diameter greater than that of the through hole.

[0012] Preferably, the sliding rod is provided with two sliding rods arranged on the front and rear sides of the top of the bottom frame.

[0013] Compared with the prior art, the utility model provides a clamping device for compressor screw rod processing, which has the following beneficial effects:

[0014] 1、the clamping device for compressor screw rod processing, through the coordinated operation of the movable mechanism and the fastening mechanism, effectively solve the support problem when long screw rod is polished. The fixed block in the movable mechanism is fixed on the top of the bottom frame on both sides, and the two sliding rods provide a stable sliding track for the sliding sleeve, so that the mounting shell can be flexibly moved and the position can be adjusted according to the length of the screw rod. The semicircle mounting seat of the fastening mechanism is in the mounting shell, when the screw rod is placed, the semicircle mounting seat is tightly attached to the screw rod under the elastic force of the spring through the sliding of the movable rod in the mounting barrel. The rollers rotatably connected to the inner mounting block not only can support the screw rod, but also can reduce the friction force during polishing to avoid damaging the surface of the screw rod. In actual use, when the screw rod is placed on the clamping device, the movable mechanism can be quickly adjusted to the appropriate position, the fastening mechanism automatically holds the screw rod, ensures the stability of the screw rod during polishing, avoids shaking and displacement, and improves the polishing precision and efficiency.

[0015] 2、the clamping device for compressor screw rod processing, through the coordinated operation of the movable mechanism and the fastening mechanism, effectively solve the support problem when long screw rod is polished. The through holes on the front and rear sides of the mounting shell cooperate with the movable rod, and the limiting block on the movable rod prevents it from being separated from the mounting barrel, ensuring the stability of the fastening mechanism. During polishing, no matter what the rotating state of the screw rod is, the rollers can continuously and stably support the screw rod, so that the polishing force applied to the surface of the screw rod by the polishing equipment is uniformly distributed, and uniform polishing is realized. When the outer surface of the long screw rod is polished, the clamping device can ensure that the screw rod is always in a stable state during the entire polishing process, greatly reduces the rate of defective products, and promotes the efficient and high-quality development of the compressor screw rod processing industry.

[0024] The present application provides the following technical scheme:

[0025] Embodiment one

[0026] Please refer to Figures 1-3A clamping device for processing compressor screws includes a base frame 1, a movable mechanism 2 installed on the top of the base frame 1, and fastening mechanisms 3 installed inside and on both sides of the movable mechanism 2.

[0027] The fastening mechanism 3 includes a semi-circular mounting base 31, which is disposed inside the movable mechanism 2. A movable rod 34 is fixedly connected to the outer side of the semi-circular mounting base 31. A mounting cylinder 35 is slidably connected to one end of the movable rod 34 near the outer side. A limit block 36 is fixedly connected to one end of the movable rod 34 inside the mounting cylinder 35. A spring 37 is sleeved on the outer side of the movable rod 34 and the limit block 36. A mounting block 33 is fixedly connected to the inner side of the semi-circular mounting base 31. A roller 32 is rotatably connected to the middle of the inner side of the mounting block 33.

[0028] Two semi-circular mounting seats 31 are symmetrically arranged inside the mounting shell 21, and rollers 32, which are evenly spaced on the inner side, can contact the screw from all directions, ensuring that the screw receives uniform support during grinding. The through holes 22 on the front and rear sides of the mounting shell 21 cooperate with the movable rod 34, and the limiting blocks 36 on the movable rod 34 prevent it from disengaging from the mounting cylinder 35, ensuring the stability of the fastening mechanism 3. During grinding, regardless of the screw's rotation state, the rollers 32 continuously and stably support the screw, ensuring that the grinding force applied to the screw surface by the grinding equipment is evenly distributed, achieving uniform grinding. When grinding the outer surface of a long screw, this clamping device ensures that the screw remains stable throughout the grinding process, greatly reducing the defect rate and promoting the efficient and high-quality development of the compressor screw processing industry.

[0029] Example 2

[0030] Please see Figures 1-4 Furthermore, based on Embodiment 1, the active mechanism 2 includes a fixed block 23, which is fixedly connected to the top two sides of the bottom frame 1. A sliding rod 24 is fixedly connected to the middle of the inner side of the fixed block 23. A sliding sleeve 25 is slidably connected to the middle of the sliding rod 24. A mounting shell 21 is fixedly connected to the top of the sliding sleeve 25.

[0031] The coordinated operation of the movable mechanism 2 and the fastening mechanism 3 effectively solves the support problem during the grinding of long screws. The fixed blocks 23 in the movable mechanism 2 are fixed to both sides of the top of the base frame 1, and the two sliding rods 24 provide a stable sliding track for the sliding sleeve 25, allowing the mounting shell 21 to move flexibly and adjust its position according to the screw length. The semi-circular mounting seat 31 of the fastening mechanism 3 is inside the mounting shell 21. When the screw is placed, the semi-circular mounting seat 31 slides within the mounting cylinder 35 under the elastic force of the spring 37 via the movable rod 34, tightly fitting the screw. The roller 32 rotatably connected to the inner mounting block 33 not only supports the screw but also reduces friction during grinding, preventing damage to the screw surface. In actual use, when the screw is placed on the clamping device, the movable mechanism 2 can quickly adjust to the appropriate position, and the fastening mechanism 3 automatically clamps the screw, ensuring the stability of the screw during grinding, preventing shaking and displacement, and improving grinding accuracy and efficiency.

[0032] Two semi-circular mounting bases 31 are provided on the left front and rear positions inside the mounting shell 21, with the two semi-circular mounting bases 31 arranged opposite each other inside the mounting shell 21.

[0033] Two semi-circular mounting bases 31 are equipped with rollers 32 arranged horizontally and equally spaced around their inner sides, forming a circle within the two semi-circular mounting bases 31.

[0034] The mounting housing 21 has through holes 22 at equal intervals on both the front and rear sides, and the movable rod 34 is slidably connected in the through holes 22.

[0035] Mounting cylinders 35 are fixedly connected to the corresponding through holes 22 on the front and rear sides of the mounting shell 21, and the diameter of the limiting block 36 is larger than the diameter of the through hole 22.

[0036] There are two sliding rods 24, which are located on the front and rear sides of the top of the bottom frame 1.

[0037] In actual operation, when this device is in use, the fixed blocks 23 in the movable mechanism 2 are fixed to the top two sides of the bottom frame 1, and the two sliding rods 24 provide a stable sliding track for the sliding sleeve 25, allowing the mounting shell 21 to move flexibly and its position to be adjusted according to the length of the screw. The semi-circular mounting seat 31 of the fastening mechanism 3 is inside the mounting shell 21. When the screw is placed, the semi-circular mounting seat 31 slides in the mounting cylinder 35 through the movable rod 34 under the elastic force of the spring 37, tightly fitting the screw. The roller 32 rotatably connected to the inner mounting block 33 not only supports the screw but also reduces friction during grinding, preventing damage to the screw surface. In actual use, when the screw is placed on the clamping device, the movable mechanism 2 can be quickly adjusted to a suitable position, and the fastening mechanism 3 automatically clamps the screw, ensuring the stability of the screw during grinding, preventing shaking and displacement, and improving grinding accuracy and efficiency.

[0038] Two semi-circular mounting seats 31 are symmetrically arranged inside the mounting shell 21, and rollers 32, which are equidistantly spaced on the inner side, can contact the screw from all directions, ensuring that the screw receives uniform support force during grinding. The through holes 22 on the front and rear sides of the mounting shell 21 cooperate with the movable rod 34, and the limiting blocks 36 on the movable rod 34 prevent it from disengaging from the mounting cylinder 35, ensuring the stability of the fastening mechanism 3. During grinding, regardless of the screw's rotation state, the rollers 32 can continuously and stably support the screw, ensuring that the grinding force applied to the screw surface by the grinding equipment is evenly distributed, achieving uniform grinding. When grinding the outer surface of a long screw, this clamping device ensures that the screw remains stable throughout the grinding process, greatly reducing the defect rate and promoting the efficient and high-quality development of the compressor screw processing industry.
