Description

Technical Field

[0001] The invention relates to the technical field of compressor equipment, and in particular to a clamping tool for a fixed scroll of a compressor. Background Art

[0002] During the machining and installation of the compressor's fixed turbine, the manual fixture used to machine the keyway threaded hole of the fixed scroll consists of a longitudinal positioning block, a transverse positioning block, a height positioning block, and a pressure head. Since the center positioning of the workpiece relies on one side edge leaning against the transverse positioning block, it is disturbed by the outer circle size and the center positioning stability is poor, resulting in a large offset of the machined threaded hole relative to the center of the workpiece. This offset will cause the installation of the fixed scroll to offset, which will have an adverse effect on the performance of the compressor. At the same time, the manual fixture has a slow clamping speed and low work efficiency.

[0003] The fixed scroll itself is a cylindrical structure, with a precision-machined spiral at one end and a cylindrical outer diameter at the other end. It is not only heavy, but also strictly prohibited from being bumped during installation. Currently, it is manually hand-held and reversed and installed on other structures, which brings great labor intensity to the operator, is extremely inconvenient to take, and there is also the risk of quality damage due to bumps and safety accidents caused by falling. Summary of the invention

[0004] Based on the above technical problems that the fixed scroll has high labor intensity for the operator during installation, is difficult to pick up, and has the quality risk of bumping and falling during installation, a clamping tool for a compressor fixed scroll is provided. The device of the present invention solves the quality risk and safety hazard of the operator having no gripping position and being easy to fall when clamping the fixed scroll to install it elsewhere, based on the special shape of the compressor fixed scroll, which is not conducive to the clamping and installation operation.

[0005] The technical means adopted by the present invention are as follows:

[0006] A clamping tool for a fixed scroll of a compressor, comprising: a lower base, a guide, a slider, an upper base, a spacer, a bolt, and a handle;

[0007] The lower base is the bottom structure that supports the entire clamping tool, and its upper surface is provided with mounting holes and positioning grooves for installation guidance and ensuring its stability;

[0008] The guide is a cylindrical structure, with its two ends connected to the lower base and the upper base respectively through spacers, and a plurality of oblique guide grooves are arranged inside to limit the movement trajectory of the slider;

[0009] There are multiple sliders, which are evenly distributed along the circumferential direction of the guide. Each slider is provided with a guide column, which is inserted into the oblique guide groove of the guide, so that the slider can move in an axial direction when the guide rotates.

[0010] The upper base is fixedly connected to the lower base through a spacer sleeve, and a straight guide groove matching the slider is provided inside the upper base to ensure the linear motion accuracy of the slider;

[0011] The spacer is a hollow cylindrical structure, used to connect and separate the lower base and the upper base, and provide a guided rotation avoidance space;

[0012] The bolts penetrate the guide, the spacer, the lower base and the upper base to fasten the components together;

[0013] The handle is welded to the outer peripheral surface of the guide and is used to drive the guide to rotate around its axis, thereby driving the slider to extend and retract in the straight guide groove to achieve clamping or releasing of the fixed scroll.

[0014] Furthermore, an inclined guide groove is arranged inside the guide, and a guide column is arranged on the slider, and the guide column is installed in the inclined guide groove. When the guide rotates relative to the lower base and the upper base, the guide column of the slider moves along the inclined guide groove, driving the slider to linearly extend and retract, thereby realizing clamping or releasing operation.

[0015] Furthermore, a straight guide groove is arranged inside the upper base, and the slider is a rectangular structure and is installed in the straight guide groove, so as to ensure that the slider always maintains stable linear extension and retraction during the process of clamping or releasing the fixed scroll.

[0016] Further, the guide and the upper base are controlled in linkage via a handle;

[0017] When the handle is in the pulled-open state, the slide block retracts into the lower base and the upper base;

[0018] When the handle is in a closed state, the slider extends into the V-shaped groove that clamps the fixed scroll to achieve stable clamping.

[0019] Furthermore, the spacer is used to support and connect the lower base and the upper base, and the design of the spacer provides an air-avoiding space for the guide, ensuring that the guide can rotate smoothly between the lower base and the upper base, thereby optimizing the telescopic action of the slider.

[0020] Furthermore, the number of the sliders is 8, which are evenly distributed in the circumferential direction between the guide and the upper base; when the sliders are extended, they precisely contact the V-grooves of the fixed scroll to form multi-point clamping, ensuring the stability and safety of clamping.

[0021] Due to the adoption of the above technical solution, compared with the prior art, the present invention has the following advantages:

[0022] 1. The present invention provides a clamping tool for a fixed scroll of a compressor, which can radially clamp a cylindrical surface by opening and closing a handle with both hands. The handle is manually pulled open and the slider is retracted, and the tool can be put on the fixed scroll. Then the handle is closed, and the slider is extended and clamped into the V-groove of the fixed scroll to achieve clamping, which is convenient for manually clamping the fixed scroll and installing it elsewhere.

[0023] 2. The present invention provides a clamping tool for a compressor fixed scroll, which solves the problems of the cylindrical outer diameter of the fixed scroll being inconvenient to pick up, the fact that bumps are not allowed during installation, and the high labor intensity of manual hand-held flipping. It avoids the quality risk of the scroll falling and improves production efficiency.

[0024] 3. The present invention provides a clamping tool for a fixed scroll of a compressor, in which a spacer is arranged inside the guide to avoid air so that the guide can rotate smoothly; the inclined guide groove inside the guide cooperates with the guide column of the slider to drive the slider to move forward and backward when the guide rotates; the straight guide groove inside the upper base ensures the linear extension and retraction of the slider, and the overall structure is compact and light, meeting the clamping requirements.

[0025] Based on the above reasons, the present invention can be widely promoted in the field of compressor equipment technology. BRIEF DESCRIPTION OF THE DRAWINGS
