Description

Technical Field

[0001] The present invention relates to the technical field of process manufacturing, and in particular, to a method for processing a watch pair. In addition, the present invention also relates to a watch pair using the method for processing a watch pair. Background Art

[0002] The key dimensions of the counter parts are the same as the dimensions of the guide vanes, and the tolerance is 1 / 10 of the tolerance of the guide vanes. The counter parts are used together with the measuring tool, and are installed on the measuring tool as standard parts. The micrometer is used to measure the value of the counter part's dimension, and the value is recorded and removed. After the guide vanes are installed, the micrometer is used to measure the value at the same position, and the guide vanes are judged by the change in the value. The characteristics of this type of counter parts are high dimensional accuracy requirements, complex surfaces, and many dimensions on the tooling drawings are double-angle dimensions. Many dimensional surfaces cannot be used as processing benchmarks, especially for some spatial dimensions, double-bevel dimensions, etc.

[0003] refer to Figure 1 , which is a pair of table parts processing dimension drawing. The processing difficulties are as follows: the arc R77mm dimensional tolerance is 0.02mm, the arc center is outside the table parts, and there is no reference for processing the arc; in the past, the arc R77 needed to be processed on a tool grinder with a clamping plate. Figure 2 The template needs to be designed for the structure of the counter-table part. The template has three holes for clamping pins and positioning the counter-table part. A through hole is made at one end of the template, and the hole is used as the center of the arc. The counter-table part is installed on the template. The hole of the template is clamped with a mandrel. The tool grinder grinds the arc of the counter-table part through the center hole of the mandrel. The operator must send the workpiece for inspection after each processing. Repeat this operation until the size is qualified. The machine tool and personnel occupy a long time, and the processing efficiency and precision are low; the distance from the intersection of the arc surface R77 and the reference line to the intersection of the 10mm groove bottom 15° angle surface and the end face The diameter of the double bevel is 40mm, with a tolerance of ±0.005mm. Since the intersection lines are vertical in space, the tolerance is difficult to guarantee. It is difficult to measure directly during processing. The symmetry center of the 10mm wide slot is on the reference line K, which is 7° with the horizontal line. The reference line K cannot be used for processing and measurement. It is difficult to measure directly during processing. The intersection size of the double bevel is 12.1499mm and 8.9029mm, with a small tolerance, and cannot be directly processed and measured. The processing datums of each size are inconsistent and cannot be related to each other, and there is no good vertical surface as a reference. On the other hand, in the processing of the double bevel, it is generally adjusted and clamped by a sine precision flat-nose pliers and then ground. However, during the grinding process, the operator cannot measure the intersection size, and the processing size is not accurate, which easily causes the parts to be scrapped due to over-tolerance. Therefore, the parts need to be sent to the three-coordinate measurement, and the machine tool needs to be re-adjusted and processed according to the results. Repeated processing and inspection are inefficient. Summary of the invention

[0036] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

Figure 2 ; Figure 6 This is a process ball tooling diagram of embodiment 1 of the present invention.

[0038] like Figures 3 to 5 As shown, the table component processing method of this embodiment, the table component is used to measure the position size of the positioning groove of the positioning guide blade, the table component is a hexahedral structure, the first profile is parallel to the third profile, one side of the second profile is connected with the first profile at a preset angle, and the other side is connected with the second profile at a preset angle, the fourth profile is located on the side opposite to the second profile, and the two sides are connected with the first profile and the third profile at 90 degrees respectively, the fifth profile is at a preset angle compared to the first profile, the sixth profile is parallel to the fifth profile, the fifth profile is located on one side of the first profile to form a first convex structure, and is located on one side of the third profile to form a second convex structure, the sixth profile forms a third convex structure, the first convex structure is provided with a first groove with a slope of 15 degrees, the outer surface of the third convex structure is an arc surface, the table component is provided with a measuring hole that passes through the fifth profile and the sixth profile, and the table component processing method includes:

[0039] S1. Processing the fourth and fifth profiles on the blank workpiece as reference surfaces respectively;

[0040] S2. Processing the measuring hole based on the fourth profile;

[0041] S3. Install a process ball on the axis of the measuring hole and measure the distance from the center of the process ball to the fifth surface;

[0042] S4. Align the center of the process ball and the fourth profile, convert the arc surface processing size from the simulated center of the arc surface to the actual value of the center of the process ball, and process the arc surface;

[0043] S5. Align the center of the process ball, convert the actual value from the simulated center of the arc surface to the center of the process ball to calculate the processing size of the first groove, and rotate 15° to process the first groove;

[0044] S6. Align the center of the process ball, use the simulated center of the arc surface as a simulated transformation line through the second profile, convert the distance from the intersection of the simulated transformation line with the fifth profile and the sixth profile to the axis of the process ball to calculate the distance between the process ball and the second profile as the processing measurement dimension, and process the second profile; it should be noted that the second profile is a double bevel, which is a spatial dimension that cannot be used as a processing reference, and it is difficult to measure the intersection dimension, which is very easy to cause out-of-tolerance scrapping. By converting the intersection dimension of the double bevel into the distance dimension between the point and the line and the surface, the fitter will level the double bevel during processing, and directly grind the second profile. It is only necessary to measure the distance from the center of the process ball to the second profile to ensure the processing dimensional accuracy, which simplifies the measurement method, greatly improves the dimensional accuracy, reduces the processing cost, and improves the processing efficiency;

[0045] It can be understood that the processing method first processes the fourth profile and the fifth profile as reference surfaces, and then uses the fourth profile as a reference to process the measuring hole, and then uses the measuring hole of the workpiece to install the process ball, and measures the distance from the center of the process ball to the fifth profile, and then can obtain the theoretical value of the distance from the center of the process ball to the simulated center of the arc surface, and then know the shortest distance between the process ball and the arc surface, based on which the processing amount of the arc surface is converted, and based on the process ball and the fourth profile as a reference, based on the above-mentioned conversion processing size, the arc surface can be processed based on precision wire cutting or coordinate grinding, replacing the tool grinding processing method in the prior art, greatly improving the work efficiency. The process of the machine tool can effectively improve the processing efficiency and precision, avoid repeated processing and multiple inspections, improve processing efficiency, avoid template design and manufacturing, reduce processing difficulty and processing cost, and at the same time, after measuring the actual value from the center of the ball to the fifth surface, the processing size of the first groove and the processing size of the second surface can be converted based on the actual position of the center of the process ball and the theoretical values ​​of each point and surface of the workpiece. The principle of using the shortest distance between points, lines and surfaces as a constant is used to take the process ball and other related surfaces as the reference to ensure dimensional accuracy based on the converted size, which effectively solves the problems of difficult clamping, difficult processing and low dimensional accuracy. The qualified rate of the manufactured parts delivered in one time reaches 100%.

[0046] It should be noted that the processing method further includes: using the standard size of the watch part in the three-dimensional drawing software to build a three-dimensional drawing model of the watch part, substituting the actual measured value of the distance between the center of the process ball and the fifth molding surface in step S3 into the model to obtain the distance from the center of the ball to the arc surface, the distance from the center of the ball to the first side wall of the first groove, the distance from the center of the ball to the second side wall of the first groove, the distance from the center of the ball to the high end of the bottom surface of the first groove, the distance from the high end of the bottom surface of the first groove to the second molding surface, and the distance from the center of the ball to the second molding surface; the three-dimensional drawing software can adopt the existing commonly used software of UG; Draw the benchmark according to the actual measured size, and use the software to directly measure the distance from the center of the process ball to each point, line, and surface, without conversion to avoid calculation errors; during processing, it is only necessary to measure the distance from the converted center of the ball to the arc surface to ensure the accuracy of the arc surface processing size, measure the distance from the converted center of the ball to the first side wall of the first groove, the distance from the center of the ball to the second side wall of the first groove, and the distance from the center of the ball to the high end of the bottom surface of the first groove to ensure the processing size of the first groove, and measure the distance from the converted center of the ball to the second surface to ensure the processing size of the double bevel.

[0047] In this embodiment, the process ball includes a spherical part, a supporting part and a positioning part. The positioning part is used to be inserted into the measuring hole, and the supporting part is used to abut against the fifth mold surface to support the spherical part. The positioning part is a pin structure. During installation, the positioning part is inserted into the measuring hole until the supporting part abuts against the fifth mold surface to complete the tooling. Based on this, the size of the spherical part, the coaxiality of the spherical part and the positioning part, and the accuracy of the end face of one end of the supporting part that cooperates with the fifth mold surface should be ensured; specifically, the spherical surface roundness of the spherical part is 0.001mm, the concentricity of the spherical part and the positioning part is 0.001mm, and the end face runout is 0.002mm; further, a knurling structure can be provided on the outer wall of the supporting part to increase surface friction so that the operator can apply force to perform loading and unloading operations.

[0048] In this embodiment, the processing method of the spherical portion includes:

[0049] A1: Optical grinding is used to grind the spherical surface of the sample turning tool, leaving 0.4mm-0.5mm;

[0050] A2. Rough grinding of the spherical surface, leaving a fine grinding amount of 0.1mm-0.15mm;

[0051] A3.Heat treatment;

[0052] A4. Semi-fine grinding;

[0053] A5. Careful research.

[0054] Since the processing size angle of the process ball is relatively high and the processing and manufacturing is relatively difficult, this processing method performs rough and fine processing on the process ball, uses an optical grinder to grind the sample turning tool to fine-turn the spherical surface of the spherical part, and leaves 0.4mm-0.5mm of grinding. After rough grinding, the spherical surface leaves 0.1mm~0.15mm of fine grinding. After heat treatment, it undergoes 2 to 3 times of semi-fine grinding and fine grinding to achieve the size requirements.

[0055] In this embodiment, the processing method of the process ball includes:

[0056] The outer wall of the lathe positioning part should be left with 0.4-0.5mm, and the end surface of the lathe support part should be left with 0.2-0.3mm;

[0057] Rough grinding of the end surface of the support part;

[0058] Finely grind the outer wall of the positioning part, and match the interference fit to 0.005-0.008 according to the measuring hole, and the runout is less than 0.01;

[0059] Finely grind the end surface of the support portion.

[0060] That is, the size requirements of the outer wall of the positioning portion that needs to cooperate with the measuring hole and the size requirements of the end face of the supporting portion that needs to cooperate with the fifth profile at the end of the measuring hole are improved and guaranteed.

[0061] In this embodiment, step S1 includes: heat treatment of the rough workpiece, grinding the fourth and fifth profiles of the rough workpiece, the surface roughness is less than Ra0.2, and the flatness is less than 0.002; the fourth and fifth profiles are used as reference surfaces, and the reference surface processing accuracy is required to be higher than the dimensional accuracy;

[0062] In this embodiment, step S2 includes: grinding the measuring hole, controlling the surface roughness to be less than Ra0.4 and the flatness to be less than 0.005; to ensure the matching accuracy with the support part; in step S3, clamping the process ball to the measuring hole, the length dimension of the process ball is affected by the tolerance, and after measuring according to the actual value, the associated processing dimensions of the processing surface and the process ball are converted according to the actual value from the process ball to each reference surface;

[0063] In this embodiment, step S4 includes: processing the arc surface by precision wire cutting or coordinate grinding; it should be noted that in the existing processing method, the workpiece needs to be clamped on the template and processed by a tool grinder. The template is designed according to the structure of the counter-table piece. The template has three holes for clamping pins and positioning the counter-table piece. A through hole is made at one end of the template, and the hole is used as the center of the arc. The counter-table piece is mounted on the template, and the hole of the template is clamped with a mandrel. The tool grinder grinds the arc of the counter-table piece through the center hole of the mandrel. The operator has to send the workpiece for inspection after each processing, and repeat this operation until the size is qualified. The machine tool and personnel occupy a long time, and the processing efficiency and precision are low. In this processing method, the distance between the process ball and the center of the arc surface can be converted by using the process ball as a reference. It is only necessary to find the center of the process ball and the fourth profile, and the process can be completed by precision cutting or coordinate grinding at one time. The arc surface obtained by processing has high precision and does not require the design and manufacture of the template. It is only necessary to verify the distance size from the center of the process ball to the arc surface to ensure the dimensional accuracy, which greatly improves production efficiency and reduces processing costs.

[0064] Step S5 includes: machining the first groove with a tool grinder or precision wire cutting; aligning the process ball before machining, and the fitter cooperates to adjust the 15° angle surface, and converts the distance from the intersection of the arc and the reference line to the intersection of the 15° angle surface and the end surface into the distance from the center of the ball to the bottom surface of the first groove, and converts the groove width into the distance between the center of the ball and the two side surfaces of the first groove, and after adjusting the angle, machining with a tool grinder or precision wire cutting to verify the above dimensions can ensure dimensional accuracy.

[0065] On the other hand, the preferred embodiment further provides a watch component, to which the above-mentioned watch component processing method is applied.

[0066] Embodiment 1

[0067] In this embodiment, taking the table parts of the background technology as an example, there are mainly four processing difficulties: the first groove of 10mm, the symmetry is 0.005mm, the parallelism is 0.005mm, the surface roughness Ra=0.2um, the symmetry center reference axis K is 7° with the center hole, and it cannot be used for processing and measurement; the R77 inner arc surface size tolerance is 0.02mm, the arc center is outside the part body, the arc processing has no reference, and it is easy to exceed the tolerance. The distance from the intersection of the arc and the reference line to the intersection of the 15° angle surface and the end face is 40mm, with a tolerance of ±0.005. Due to the distance from the point to the line, the intersection size tolerance is not easy to guarantee; the double angle surface (second profile) is out of tolerance, the intersection size 12.1499mm and 8.9029mm have small tolerances, and cannot be directly processed and measured; the processing datums of various dimensions are inconsistent, cannot be correlated with each other, and measurement is difficult;

After measuring according to the actual values, the actual distance between the process ball and the fifth profile is 10.868mm, and the actual distance between the process ball and the fourth profile is 35mm. According to the actual values ​​of the process ball to each reference surface, the associated processing dimensions of the processing surface and the process ball are converted.

Align the center of the process ball and the fourth profile, convert the arc surface processing size from the simulated center of the arc surface to the actual value of the center of the process ball, and process the arc surface; use precision wire cutting or coordinate grinding to process the arc surface. The operator only needs to align the center of the ball and the upper end face of the table piece, and the processing is in place at one time. The processed arc has high precision, and no template is required, which improves production efficiency. When measuring, only the size of 56.8561 needs to be measured;

After adjusting the angle, use a tool grinder or precision wire cutting to verify the above dimensions to ensure dimensional accuracy.

[0074] S6. Align the center of the process ball, use the simulated center of the arc surface as a simulated transformation line through the second profile, convert the distance from the intersection of the simulated transformation line with the fifth profile and the sixth profile to the axis of the process ball to calculate the distance between the process ball and the second profile as the processing measurement dimension, and process the second profile; among which, the intersection dimensions of 8.9029mm and 12.1499mm are converted into the dimension of 13.9449mm from the ball to the surface; the fitter uses the sine precision flat-nose pliers to level the double bevels, and the flat grinder directly grinds the double bevels. When measuring, it is only necessary to measure whether the 13.9449mm dimension is processed in place;
