Description

Technical Field

[0001] The present invention relates to the technical field of clock part detection, and particularly relates to a geometric detection device for clock moving parts. Background Art

[0002] It is very difficult to perform dimensional and geometric inspections of clock parts because the parts are very small in size and have extremely low tolerances, and the amplitude is usually significantly less than the resolution of conventional multi-functional measuring devices (such as three-dimensional measuring centers or the like). Therefore, in-process inspections usually require sampling and passing in an inspection room or laboratory for time-consuming and expensive verification, or actually dedicated, non-multi-functional and very expensive tools.

[0003] In the prior art, there is a device for portable inspection of minute clock parts. For example, a geometric inspection device for clock moving parts with the publication number CN112639389B includes a headstock and a tailstock on a common base. The headstock supports a first mandrel defining a first axis of rotation, and the tailstock defines a second axis of rotation. The headstock or the tailstock can move relative to the common base in a common direction parallel to the first axis of rotation. The device includes an interchangeable micro-centering device.

[0004] This inspection device adsorbs and fixes the parts through an uncentered device for inspection. When this inspection device is fixed, it cannot drive the parts to rotate. During the inspection process, the user needs to manually turn the parts. The parts are too minute to be directly turned, so there are great limitations in the process of performing a full-range geometric inspection on the surface of the parts. Since the volume of the parts is only at the millimeter level, when directly contacting and fixing both ends of the parts, it may cause excessive stress on both ends of the parts and damage the parts themselves. Summary of the Invention

[0005] The object of the present invention is to solve the problem that the inspection device in the above background art cannot rotate the fixed minute parts and thus cannot perform a full-range geometric inspection, and that direct contact at both ends of millimeter-level parts may cause damage to the parts themselves due to excessive stress, and to propose a geometric inspection device for clock moving parts.

[0006] The object of the present invention can be achieved by the following technical solutions:

[0007] A geometric inspection device for clock moving parts, including a bottom plate, on the top surface of which a fixing structure is provided. The fixing structure includes:

[0019] Beneficial effects of the present invention:

[0020] (1) The geometric detection device for the movable parts of a watch of the present invention is provided with a fixing structure and a pressing structure. The magnetic parts can be placed in the gap formed by the pressing block and the fixing block, so that the magnetic adsorption disks on both sides fix the parts; then the pressing block gradually moves away from the fixing block, so that the magnetic adsorption disks slide relatively and drive the parts to rotate in the horizontal axis direction.

At the same time, the adjustment wheel can also drive the parts to rotate to perform geometric detection on the surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The fixed block 61 and the pressing block 73 are detachably provided with a non-magnetic fixed component 8 on one side opposite to each other. The non-magnetic fixed component 8 includes a mounting plate 81. A clamping plate 82 is provided on one side of the mounting plate 81. The shape of the clamping plate 82 is adapted to the shape of the sliding groove 62. The clamping plate 82 can be inserted into the sliding groove 62 for clamping and fixing. The length of the clamping plate 82 is less than the length of the sliding groove 62, providing a placement space for the magnetic adsorption disk 63. A setting cylinder 83 is rotatably provided inside the mounting plate 81 and the clamping plate 82. A mounting groove 86 is provided inside the setting cylinder 83. A plurality of air inlet grooves 84 are provided on the circumferential surface of the setting cylinder 83. The air inlet grooves 84 connect the mounting groove 86 with the outside.

A fixed magnetic block 85 is fixedly connected to one side of the setting cylinder 83 close to the air inlet groove 84. The exposed surface of the fixed magnetic block 85 and the exposed surface of the permanent magnet 68 are mutually adsorbed. A mounting ring 87 is fixedly connected inside the mounting groove 86, and a resistance block 89 is slidably provided on a side of the mounting ring 87 away from the air inlet groove 84, and a return spring 88 is provided between the resistance block 89 and the mounting ring 87. An elastic cotton 810 is provided on one side of the resistance block 89.

[0034] When using this geometric detection device for clockwork moving parts, it is necessary to fixedly display the parts within the clockwork at the millimeter level. When the part to be detected is a part that can be magnetically adsorbed, such as metal, the magnetic adsorption disks 63 inside the sliding grooves 62 of the pressing block 73 and the fixing block 61 are rotated to different sides. Then, the electric push rod 4 is started, so that the electric push rod 4 drives the pressing structure 7 to approach the fixing block 61, making the pressing block 73 of the pressing structure 7 in close contact with the fixing block 61. The buffer spring 72 is compressed to make the placing pad 66 provided on one side of the pressing block 73 and the fixing block 61 in close contact. At this time, a gap is exposed on the top surfaces of the pressing block 73 and the fixing block 61 due to the setting of the placing pad 66, and the part to be processed is placed through the gap. After the part falls onto the placing pad 66, it will be adsorbed and fixed by the magnetic adsorption disks 63 in the two side sliding grooves 62. Subsequently, the electric push rod 4 is started, and the electric push rod 4 drives the extension rod to move, so that the buffer spring 72 is restored to make the connection between the part and the magnetic adsorption disk 63 stable. Then, the pressing block 73 starts to gradually move away from the fixing block 61. Since the two ends of the part are adsorbed and fixed by the magnetic adsorption disks 63, as the pressing block 73 moves, the two ends of the part drive the magnetic adsorption disks 63 to slide, and rotate between the two ends of the part and the magnetic adsorption disks 63, so that the two ends of the part are gradually rotated into the setting holes 64 for positioning. Until the magnetic adsorption disks 63 on both sides move into the positioning center holes 65 in the setting grooves 67, at this time, the magnetic adsorption disks 63 are adsorbed by the permanent magnets 68 and move into the positioning center holes 65. At this time, the magnetic adsorption disks 63 fix the two ends of the part, causing the pressing block 73 to drive the buffer spring 72 to make a sudden displacement, prompting the staff that the part has moved to the horizontal position. Subsequently, the staff detects the geometric data on the surface of the part through the detection mirror 5. The detection mirror 5 can observe the part above through the reflecting mirror 9. By turning the adjusting wheel 611, the adjusting wheel 611 drives the transmission gear 610 to rotate. The connecting gear 69 engaged with the transmission gear 610 drives the permanent magnet 68 in the fixing block 61 to rotate. The circular magnetic adsorption disk 63 fixed by the permanent magnet 68 rotates, driving the part fixed in the middle to rotate, so that the detection mirror 5 can perform a full-range detection on the surface of the part. When this detection mirror 5 performs geometric detection on a non-magnetic part, a non-magnetic fixing component 8 is installed on the surfaces of the pressing block 73 and the fixing block 61. The mounting plate 81 is fixedly engaged on the surfaces of the pressing block 73 and the fixing block 61 through the engaging plate 82. The setting cylinder 83 of the mounting plate 81 extends into the positioning center hole 65, and the fixing magnet block 85 on one side is adsorbed and fixed with the permanent magnet 68, thus completing the installation of the mounting plate 81. Subsequently, the two ends of the part are placed in the mounting grooves 86 of the two side mounting plates 81. At this time, the small air pump 612 inside the fixing block 61 and the pressing block 73 is started, and the small air pump 612 passes air through the connecting channel and the air inlet groove 84 into the setting cylinder 83.The contact block 89 inside the setting cylinder 83 is moved by the action of a small air flow, and the contact block 89 clamps and fixes both ends of the part through the elastic cotton 810. The small air pump 612 drives the contact block 89 to clamp the part through air pressure, avoiding damage and deformation to the part body. At the same time, the rotation of the adjusting wheel 611 indirectly drives the rotation of the permanent magnet 68, indirectly driving the rotation of the fixed setting cylinder 83, so that the clamped part rotates to comprehensively detect the surface geometry.

[0035] The working principle of the present invention: A geometric detection device for a clock moving part of the present invention is provided with a fixing structure 6 and a pressing structure 7. The magnetic part can be placed in the gap formed by the pressing block 73 and the fixing block 61, and the magnetic adsorption disks 63 on both sides fix the part; then the pressing block 73 gradually moves away from the fixing block 61, so that the magnetic adsorption disks 63 slide relatively to drive the part to rotate to the horizontal axis direction. When the sudden displacement of the pressing block 73 indicates that the surface part has rotated to the horizontal direction, the small part is smoothly rotated to the horizontal direction and adsorbed and clamped at both ends; avoiding directly clamping and fixing both ends of the part, excessive force at both ends directly causes damage and deformation of the part itself. During fixation, by rotating the adjusting wheel 611, the adjusting wheel 611 indirectly drives the rotation of the permanent magnet 68, thereby rotating the fixed part, enabling the detection mirror 5 to perform a comprehensive geometric detection on the surface of the part; by providing a non-magnetic fixing component 8, the mounting plate 81 of the non-magnetic fixing component 8 can be installed on the surfaces of the pressing block 73 and the fixing block 61. Place the non-magnetic part in the mounting plate 81, and the air pressure of the small air pump 612 drives the contact block 89 to clamp and fix both ends of the part, avoiding deformation of the part due to excessive force. At the same time, the adjusting wheel 611 can also drive the part to rotate to detect the surface geometry.

All equivalent changes and improvements made according to the scope of the present invention application should still fall within the scope covered by the patent of the present invention.
