Description

Technical Field

[0001] The invention relates to the technical field of mechanical manufacturing, and in particular to a manufacturing method for controlling thrust of a metal guide rail and a plastic guide rail groove. Background Art

[0002] With the development of China's high-end manufacturing industry, the requirements for equipment performance are getting higher and higher, and the application of plastic parts in mechanical equipment is becoming more and more extensive. However, achieving high-precision matching between metal guide rails and plastic guide rail grooves, thereby ensuring that the guide rails are neither loose nor tight in the base, and move at a constant speed without jamming under a certain thrust, puts higher requirements on the manufacturing of plastic guide rail grooves and metal guide rails.

[0003] Plastic materials have high strength and rigidity, excellent dimensional stability, low water absorption, good electrical properties and wear resistance, self-lubrication and friction properties, and corrosion resistance. However, their disadvantages are that they are sensitive to temperature during processing, are prone to thermal decomposition in high temperature environments, have large shrinkage rates, and are prone to deformation after processing. Therefore, after the metal guide rail and the plastic guide rail groove are assembled, it is a major technical challenge to reasonably control the thrust of uniform motion and prevent jamming.

[0004] Therefore, technicians in this field are committed to developing a manufacturing method for controlling thrust of a metal guide rail and a plastic guide rail groove to overcome the problems existing in the prior art. Summary of the invention

[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is how to reasonably control the thrust of uniform motion and prevent jamming of the metal guide rail and the plastic guide rail groove after the metal guide rail and the plastic guide rail groove are assembled.

[0006] To achieve the above object, the present invention provides a method for manufacturing a metal guide rail and a plastic guide rail groove to control thrust, comprising the following steps:

[0007] Step 1: Rough processing of the metal guide rail;

[0008] Step 2: Finishing the metal guide rail;

[0009] Step 3: Use a contoured go / no-go gauge to inspect the metal guide rail;

[0010] Step 4, rough machining the plastic guide rail groove;

[0011] Step 5: Finishing the plastic guide rail groove;

[0012] Step 6: Use the manufactured metal guide rail to check the plastic guide rail groove.

[0013] Furthermore, the step 1 specifically includes: using a contoured metal guide rail forming tool to remove most of the excess on the guide rail surfaces on both sides of the metal guide rail.

[0014] Furthermore, the step 2 specifically includes: using a contoured metal guide rail forming tool to perform finish machining on the metal guide rail.

[0015] Furthermore, the contoured go / no-go gauge in step 3 includes a go gauge and a no-go gauge.

[0016] Further, the step 3 specifically includes: determining whether the metal guide rail is qualified by checking whether the finely machined metal guide rail can pass the go gauge and stop if it does not pass the stop gauge.

[0017] Furthermore, the step 4 specifically includes: using a plastic guide rail groove forming tool to remove most of the excess within the guide rail contact surface on both sides of the plastic guide rail groove and all the excess of the outer contour.

[0018] Furthermore, the step 5 specifically includes: using a plastic guide rail groove forming tool to perform fine processing on the plastic guide rail groove.

[0019] Furthermore, step 6 specifically includes: checking whether the manufactured metal guide rail can pass through the plastic guide rail groove, and controlling the metal guide rail to move at a uniform speed without jamming under a predetermined thrust.

[0020] Furthermore, the metal guide rail forming tool is a straight-edged three-edged ancient forming tool made of cemented carbide.

[0021] Furthermore, the plastic guide rail groove forming tool is a spiral-edged three-edged dovetail forming tool made of cemented carbide.

[0022] The beneficial effects of the present invention are:

[0023] 1. The conformation of the metal guide rail and the angle of the metal guide rail are ensured by the profiling go / no-go gauge to ensure the consistency of the product size and shape.

[0024] 2. By using two forming tools, ensure that the angle and shape between the metal guide rail and the plastic guide groove are consistent.

[0025] 3. Pre-process the metal guide rail and then make the manufacturing sequence of the plastic guide rail groove, and use the metal guide rail itself as a check fixture to control the thrust after the guide rail is installed in the plastic guide rail groove.

[0036] The following describes the preferred embodiments of the present invention with reference to the drawings in the specification, so that the technical content is clearer and easier to understand. The present invention can be embodied in many different forms of embodiments, and the protection scope of the present invention is not limited to the embodiments mentioned in the text.

[0037] In the drawings, components with the same structure are indicated by the same numerical reference numerals, and components with similar structures or functions are indicated by similar numerical reference numerals. The size and thickness of each component shown in the drawings are arbitrarily shown, and the present invention does not limit the size and thickness of each component. In order to make the illustration clearer, the thickness of the components is appropriately exaggerated in some places in the drawings.

[0038] like Figure 2-3 As shown, the metal guide rail 1 has two side guide rail surfaces, and the cross-sections of the two side guide rail surfaces of the metal guide rail 1 are in the shape of a dovetail groove.

[0039] like Figure 4-5 As shown, the plastic guide rail groove 2 has two side guide rail contact surfaces, and the angles and sizes of the two side guide rail contact surfaces of the plastic guide rail groove 2 are consistent with those of the two side guide rail surfaces of the metal guide rail 1. The cross-section of the two side guide rail contact surfaces of the plastic guide rail groove 2 is a dovetail shape.

[0040] like Figure 1 As shown, when the metal guide rail 1 is installed in the plastic guide rail groove 2, it needs to move at a constant speed within a predetermined thrust value. First, the consistency of the metal guide rail 1 must be ensured to be good and its deformation must be strictly controlled. The angles and dimensions of the guide surfaces on both sides of the metal guide rail 1 must be precisely matched with the guide contact surfaces on both sides of the plastic guide rail groove 2, and the angles, dimensions and surface roughness of these contact mating surfaces must be strictly controlled.

[0041] The present invention provides a method for manufacturing a metal guide rail and a plastic guide rail groove to control thrust, comprising the following steps:

[0042] First, the metal guide rail 1 is rough-machined: a metal guide rail forming tool 6 (such as Figure 6 (as shown) most of the excess on both sides of the metal guide rail 1 is removed.

[0043] Then, the metal guide rail 1 is finely processed using a profiling metal guide rail forming tool 6 to ensure the straightness, flatness and parallelism of the metal guide rail 1 .

[0044] like Figure 6 As shown, the metal guide rail forming tool 6 is a straight-edged three-edged ancient-style forming tool made of cemented carbide. "Ancient-style" means that the cross-section of the head of the metal guide rail forming tool 6 has a dovetail shape that matches the guide rail surfaces on both sides of the metal guide rail 1.

[0045] The angle and size of the metal guide rail 1 have an extremely important influence on the thrust value after assembly with the plastic guide groove 2. Therefore, it is necessary to focus on controlling the consistency, size and roughness of the metal guide rail 1. When using the metal guide rail forming tool 6 to perform high-speed fine processing on the metal guide rail 1, reasonable processing parameters can effectively ensure the surface roughness of the metal guide rail 1. However, the size and angle of the metal guide rail 1 rely on traditional measurement methods and are prone to cumulative errors, resulting in correct angles but incorrect sizes, or correct sizes but deviations in angles. For this reason, we designed a contoured go / no-go gauge 3 (such as Figure 7 , 8 It is manufactured strictly according to certain tolerances and uses slow wire cutting to ensure that the shape and angle meet the requirements.

[0046] like Figure 7 , 8 As shown, the go / no-go gauge 3 includes a go gauge 4 and a no-go gauge 5, the shapes of which are consistent with the shapes of the metal guide rail 1, and the size of the go gauge 4 is slightly larger than the size of the metal guide rail 1 required by the drawing, and the size of the no-go gauge 5 is slightly smaller than the size of the metal guide rail 1 required by the drawing. As long as the metal guide rail 1 can pass the go gauge 4 and stop at the no-go gauge 5 after fine processing, it can be determined that the metal guide rail 1 is qualified. All metal guide rails 1 use the go / no-go gauge 3 uniformly, which can ensure the consistency and dimensional accuracy of the metal guide rails 1.

[0047] After the metal guide rail 1 is processed into a finished product according to the above method in advance, the plastic guide rail groove 2 is manufactured.

[0048] First, the plastic guide groove 2 is rough-machined: a plastic guide groove forming tool 7 (such as Fig. 9 As shown in the figure, most of the margins in the guide rail contact surfaces on both sides of the plastic guide rail groove 2 and all the margins of the outer contour are removed, leaving only a small amount of margin for fine machining.

[0049] like Fig. 9 As shown, the plastic guide groove forming tool 7 is a spiral blade three-edge dovetail forming tool made of hard alloy. "Dovetail" means that the cross section of the head of the plastic guide groove forming tool 7 has a dovetail groove shape that matches the guide rail contact surfaces on both sides of the plastic guide groove 1.

[0050] Then, the plastic guide groove 2 is finely processed using the plastic guide groove forming tool 7, and the manufactured metal guide rail 1 is used as a detection tool to adapt and control the size and consistency of the guide contact surfaces on both sides of the plastic guide groove 2, avoiding the error caused by directly measuring the size and angle of the guide contact surfaces on both sides of the plastic guide groove 2 and the metal guide rail 1. In this way, the consistency of the metal guide rail 1 and the plastic guide groove 2 is higher, and it is more convenient to match and realize thrust control.

[0051] The preferred specific embodiments of the present invention are described in detail above. It should be understood that ordinary technicians in the field can make many modifications and changes based on the concept of the present invention without creative work. Therefore, all technical solutions that can be obtained by technicians in the technical field based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of the prior art should be within the scope of protection determined by the claims.
