Description

Technical Field

[0001] The present invention belongs to the technical field of gear processing detection, and in particular relates to a device and method for detecting the relative axial size of a fixed diameter portion on a rotating conical surface. Background Art

[0002] During the inspection of the conical surface of bevel gears before and after turning, since the relative axial dimension of the fixed diameter on the conical surface is a spatial dimension, general inspection tools cannot measure it directly. The traditional inspection method is to establish axial and radial reference measurements on a three-coordinate machine. This method has shortcomings: during the first-piece processing, the workpiece cannot be measured for allowances before reaching the finished product size, and the first-piece processing is easily scrapped due to out-of-tolerance. The inspection method in the existing technology is to establish axial and radial reference measurements on a three-coordinate machine. The turnover, clamping, and alignment measurements are very cumbersome, inefficient, require a lot of man-hours, and have high measurement costs. Summary of the Invention

[0003] In response to the problems existing in the prior art, the present invention provides a device and method for detecting the relative axial size of a fixed diameter on a rotating conical surface, which can quickly detect the rotating conical surface and improve the detection efficiency and yield rate.

[0004] The present invention is achieved through the following technical solutions:

[0005] A device for detecting the relative axial dimension of a fixed diameter portion on a rotating conical surface, comprising a fixed plate and a limit block arranged at the bottom of a pass-stop end plate;

[0006] A through-end abutment plate is provided on one side of the fixed plate, and a stop-end abutment plate is provided on the other side. The limit block is used to clamp the rotary cone radial connecting rod. The spacing between the fixed plate and the through-end abutment plate and the stop-end abutment plate is unequal.

[0007] The abutting side edges of the through-end abutment plate and the stop-end abutment plate are both parallel to the rotary cone surface and are used for abutting the rotary cone inclined surface.

[0008] Furthermore, the limiting block includes a first limiting plate and a second limiting plate, and the angle between the first limiting plate and the second limiting plate is ninety degrees.

[0009] Furthermore, the maximum distance between the first limiting plate and the second limiting plate is equal to the diameter of the rotary cone radial connecting rod.

[0010] Furthermore, the top ends of the first limiting plate and the second limiting plate are connected by a horizontal plate.

[0011] Furthermore, a through-end vertical groove and a stop-end vertical groove are provided on the sides of the through-end abutment plate and the stop-end abutment plate close to the fixed plate.

[0012] Furthermore, the width difference between the through-end vertical groove and the stop-end vertical groove is equal to the machining accuracy error threshold of the rotary cone surface.

[0013] Furthermore, the extension lines of the abutting sides of the through-end abutment plate and the stop-end abutment plate are arranged to intersect.

[0014] Furthermore, the fixing plate is provided with a plurality of mounting holes, and the mounting holes are used to detachably connect the through-end abutment plate and the stop-end abutment plate by means of screws.

[0015] Furthermore, the plurality of mounting holes include a first mounting hole and a second mounting hole, and the first mounting hole and the second mounting hole have different apertures.

[0016] A method for detecting the relative axial dimension of a fixed diameter portion on a rotating conical surface comprises the following steps:

[0017] S1: Place the rotating cone close to the through-end stop plate, clamp the limit block to the radial connecting rod of the rotating cone, and make the positioning end face of the rotating cone touch the side of the limit block. Rotate the rotating cone. If there is no jamming between the rotating cone surface and the through-end stop plate throughout the entire circle, proceed to the next step. If jamming occurs, re-process the rotating cone surface and repeat this step again.

[0018] S2: Place the rotary cone close to the stop plate, clamp the limit block to the radial connecting rod of the rotary cone, and make the positioning end face of the rotary cone touch the side of the limit block. Rotate the rotary cone to determine whether there is a gap between the contact side of the stop plate and the rotary cone surface. If there is a gap, the rotary cone is scrapped. If there is no gap, it meets the processing standards.

[0019] Compared with the prior art, the present invention has the following beneficial technical effects:

[0020] The cam is secured to the bottom of the workpiece and has a retaining plate which is adapted to engage the guide rails of the machine tool and to provide a secure connection between the machine and the workpiece, and the cam is secured to the bottom of the workpiece so that the workpiece can be reliably and precisely controlled.

DETAILED DESCRIPTION

[0026] The present invention will be further described in detail below with reference to specific embodiments, which are intended to explain the present invention rather than to limit it.

[0027] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0028] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0029] The present invention provides a device for detecting the relative axial size of a fixed diameter portion of a rotating cone surface. Figure 1 and Figure 2As shown, it includes a fixed plate 1 and a limit block 2 arranged at the bottom of the pass-stop end plate 1;

[0030] A through-end abutment plate 3 is provided on one side of the fixed plate 1, and a stop-end abutment plate 4 is provided on the other side. The limit block 2 is used to clamp the rotary cone radial connecting rod. The spacing between the fixed plate 1 and the through-end abutment plate 3 and the stop-end abutment plate 4 is unequal.

[0031] The abutting side edges of the through-end abutment plate 3 and the stop-end abutment plate 4 are both parallel to the rotary cone surface and are used to abut the rotary cone inclined surface.

[0032] Preferably, the limit block 2 includes a first limit plate 20 and a second limit plate 21, and the angle between the first limit plate 20 and the second limit plate 21 is ninety degrees; further, the maximum distance between the first limit plate 20 and the second limit plate 21 is equal to the diameter of the rotary cone radial connecting rod; further, the top ends of the first limit plate 20 and the second limit plate 21 are connected by a horizontal plate 22;

[0033] Specifically, the horizontal plate 22 must not interfere with the rotating cone radial connecting rod in structure. At the same time, the horizontal plate 22 is used to ensure that the first limit plate 20 and the second limit plate 21 are tangent to the outer circle of the rotating cone radial connecting rod when they are clamped on it, so that when the rotating cone radial connecting rod is stuck during rotation, no offset will occur, thereby ensuring the stability and accuracy of the detection.

[0034] Preferably, the through-end stop plate 3 and the stop-end stop plate 4 are provided with a through-end vertical groove 5 and a stop-end vertical groove 6 on the side close to the fixed plate; further, the width difference between the through-end vertical groove 5 and the stop-end vertical groove 6 is equal to the machining accuracy error threshold of the rotating cone surface; specifically, the through-end vertical groove 5 and the stop-end vertical groove 6 are used to make way for the outer circle of the large end of the rotating cone, and at the same time, the width of the through-end vertical groove 5 and the stop-end vertical groove 6 is used to determine whether the machining accuracy is between the maximum and minimum error values.

[0035] Preferably, the extension lines of the abutting sides of the through-end abutment plate 3 and the stop-end abutment plate 4 are arranged to intersect. Such an arrangement can satisfy the detection that only one side of the rotating cone is provided with a radial connecting rod, thereby improving the versatility and applicability of the present application.

[0036] Preferably, a plurality of mounting holes 7 are provided on the fixing plate 1, and the mounting holes 7 are used for detachably connecting the through-end stop plate 3 and the stop-end stop plate 4 by screws; the plurality of mounting holes 7 include a first mounting hole 70 and a second mounting hole 71, and the apertures of the first mounting hole 70 and the second mounting hole 71 are different; since the present application may foreseeably cause jamming during the detection process, it is particularly important to fasten the through-end stop plate 3 and the stop-end stop plate 4, and if they become loose, it will have a significant impact on the detection results, so two mounting holes 7 with different internal views are required to cooperate with each other to improve the connection strength.

[0037] The present invention provides a method for detecting the relative axial size of a fixed diameter portion on a rotating cone surface. Figure 3 and Figure 4 As shown, the following steps are included:

[0038] S1: Place the rotating cone close to the through-end stop plate 3, clamp the limit block 2 to the radial connecting rod of the rotating cone, and make the positioning end surface of the rotating cone contact the side of the limit block 2. Rotate the rotating cone. If there is no jamming between the rotating cone surface and the through-end stop plate 3 throughout the entire circle, proceed to the next step. If jamming occurs, reprocess the rotating cone surface and repeat this step again.

[0039] S2: Place the rotating cone close to the end stop plate 4, with the limit block 2 clamped to the radial connecting rod of the rotating cone. The positioning end face of the rotating cone is in contact with the side of the limit block 2. Rotate the rotating cone to determine whether there is a gap between the contact side of the end stop plate 4 and the rotating cone surface. If there is a gap, the rotating cone is scrapped. If there is no gap, it meets the processing standards. Determine whether there is a gap between the contact side of the end stop plate 4 and the rotating cone surface. If there is a gap, the rotating cone is scrapped. If there is no gap, it meets the processing standards.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
