Description

Technical Field

[0001] This utility model belongs to the field of ceramic structural components, specifically relating to a processing and fixing fixture applicable to multiple processes. Background Technology

[0002] Ceramic structural component machining fixtures are key tools used to fix ceramic structural components to ensure machining accuracy. Their design needs to combine the characteristics of ceramic structural components with machining requirements. The core function of ceramic structural component machining fixtures is to stably fix ceramic structural components and prevent them from being displaced due to vibration or external force during machining, thereby ensuring machining accuracy.

[0003] Existing fixtures for machining ceramic structural parts have significant drawbacks in practical applications: Because the fixture's obstruction area directly covers specific parts of the ceramic structural part, it prevents access to these obstructed areas for machining. This forces operators to interrupt the machining process and adjust the workpiece position to expose the surface to be machined, severely reducing production efficiency. Furthermore, the fixture's rigid, integrated structure means its fixed dimensions can only accommodate ceramic structural parts of a single specification. When machining ceramic structural parts of different diameters, the entire fixture must be replaced, increasing equipment costs and impacting the production line's flexibility.

[0004] In view of this, the present invention provides a processing fixture applicable to multiple processes to solve the problems of low efficiency and poor adaptability of processing fixtures. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: a processing fixture applicable to multiple processes, comprising: a base, a processing table assembly connected to the upper surface of the base for placing workpieces, wherein two sets of first positioning components are centrally symmetrically arranged on both sides of the processing table assembly on the upper surface of the base, and two sets of second positioning components are centrally symmetrically arranged on both ends of the processing table assembly on the upper surface of the base.

[0006] The first positioning component includes a first rotary cylinder mounted on the upper surface of the base, a first pressure plate connected to the movable end of the first rotary cylinder, and a first rubber pad connected to the lower surface of the first pressure plate.

[0007] The second positioning component includes a second rotary cylinder mounted on the upper surface of the base, a second pressure plate connected to the movable end of the second rotary cylinder, and a second rubber pad connected to the lower surface of the second pressure plate.

[0008] As a preferred embodiment of this utility model of a processing fixture applicable to multiple processes, the processing table assembly includes two sets of vertical plates connected to the upper surface of the base, and a horizontal plate connected to the top of the two sets of vertical plates.

[0009] As a preferred embodiment of the present invention, which is applicable to a multi-process machining fixture, the surface of the machining table assembly is symmetrically provided with side limiting components for limiting the two sides of the workpiece. The side limiting components include side limiting plates symmetrically arranged on the upper surface of the machining table assembly, first guide portions respectively disposed between the two sets of side limiting plates and the machining table assembly, and adjustment portions connected between the two sets of first guide portions and connected to the machining table assembly.

[0010] As a preferred embodiment of the present invention, which is applicable to a multi-process processing fixture, the first guide portion includes a wedge-shaped slider connected to the bottom side of two sets of side limiting plates, and two sets of wedge-shaped grooves opened on the surface of the horizontal plate and adapted to the size of the wedge-shaped slider.

[0011] As a preferred embodiment of this utility model of a processing fixture applicable to multiple processes, the adjusting part includes a helical tube that is respectively connected through the interior of two wedge-shaped sliders, a threaded bidirectional lead screw that is connected through the interior of the two helical tubes, a bearing seat sleeved on the surface of the bidirectional lead screw and mounted on the inner wall of the horizontal plate, a driven bevel gear connected to the surface of the bidirectional lead screw, a drive motor mounted on the inner wall of the horizontal plate, and a driving bevel gear mounted on the output end of the drive motor and meshing with the driven bevel gear.

[0012] As a preferred embodiment of this utility model of a processing fixture applicable to multiple processes, the surface of the processing table assembly is also symmetrically provided with end limiting components for limiting the two ends of the workpiece.

[0013] The end limiting assembly includes two sets of movable seats that are fitted into the inner wall of the horizontal plate and symmetrically arranged, a second guide portion that is respectively disposed between the two sets of movable seats and the horizontal plate, a limiting block that is respectively connected to the surface of the two sets of movable seats, and a telescopic rod that is respectively connected to the inner wall of the movable seat and installed on the surface of the horizontal plate.

[0014] As a preferred embodiment of this utility model of a processing fixture applicable to multiple processes, the second guide portion includes guide blocks respectively connected to both sides of the movable seat, and guide grooves formed on the inner wall of the horizontal plate and adapted to the guide blocks.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, after the workpiece is processed, the second rotary cylinder operates to drive the second pressure plate and the second rubber pad to rotate and rise. When the second pressure plate drives the second rubber pad to rotate 90°, at the same time, the first rotary cylinder operates to drive the first rubber pad to rotate and fall through the first pressure plate. When the first pressure plate drives the first rubber pad to rotate 90°, it can squeeze the workpiece. This can realize the repositioning of the workpiece to facilitate the processing of the unprocessed parts of the workpiece, thereby forming continuous and comprehensive processing.

[0017] In this invention, when the drive motor is running, it drives the active bevel gear to rotate. When the active bevel gear rotates, it drives the bidirectional lead screw to rotate through the driven bevel gear. When the bidirectional lead screw rotates, it drives the two wedge-shaped sliders to move in the opposite direction through the two solenoids. The two wedge-shaped sliders move in the opposite direction, which drives the two side limiting plates to move in the opposite direction, thereby limiting the workpieces of different diameters on both sides.

[0018] In this invention, when the telescopic rod is in operation, it drives the movable seat to move laterally. The lateral movement of the movable seat drives the adjustment of the position of the limiting block, thus limiting the position of the block and adapting to workpieces of different lengths so as to limit their ends.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model relates to a processing fixture applicable to multiple processes, such as... Figures 1-6 As shown, it includes: a base 1, a processing table assembly 2 connected to the upper surface of the base 1 for placing workpieces, two sets of first positioning components 4 are centrally symmetrically arranged on both sides of the processing table assembly 2 on the upper surface of the base 1, two sets of second positioning components 5 are centrally symmetrically arranged on both ends of the processing table assembly 2 on the upper surface of the base 1, side limiting components 6 for limiting the workpiece on both sides are symmetrically arranged on the surface of the processing table assembly 2, and end limiting components 7 for limiting the workpiece at both ends are also symmetrically arranged on the surface of the processing table assembly 2; the processing table assembly 2 can be used to place ceramic structure workpieces, and the ceramic structure workpieces are positioned by the cooperation of the first positioning components 4 and the second positioning components 5.

[0029] The first positioning component 4 includes a first rotary cylinder 41 mounted on the upper surface of the base 1, a first pressure plate 42 connected to the movable end of the first rotary cylinder 41, and a first rubber pad 43 connected to the lower surface of the first pressure plate 42.

[0030] The second positioning component 5 includes a second rotary cylinder 51 mounted on the upper surface of the base 1, a second pressure plate 52 connected to the movable end of the second rotary cylinder 51, and a second rubber pad 53 connected to the lower surface of the second pressure plate 52.

[0031] The side limiting assembly 6 includes side limiting plates 61 symmetrically arranged on the upper surface of the processing table assembly 2, first guide portions 62 respectively disposed between the two sets of side limiting plates 61 and the processing table assembly 2, and adjustment portions 63 connected between the two sets of first guide portions 62 and connected to the processing table assembly 2.

[0032] The processing table assembly 2 includes two sets of upright plates 21 connected to the upper surface of the base 1, and a horizontal plate 22 connected to the top of the two sets of upright plates 21.

[0033] Furthermore, the surface of the processing table assembly 2 is symmetrically provided with side limiting components 6 for limiting the two sides of the workpiece. The side limiting components 6 include side limiting plates 61 symmetrically arranged on the upper surface of the processing table assembly 2, first guide portions 62 respectively disposed between the two sets of side limiting plates 61 and the processing table assembly 2, and adjustment portions 63 connected between the two sets of first guide portions 62 and connected to the processing table assembly 2.

[0034] Furthermore, the first guide portion 62 includes wedge-shaped sliders 621 connected to the bottom sides of the two sets of side limiting plates 61, and two sets of wedge-shaped grooves 622 formed on the surface of the horizontal plate 22 and adapted to the size of the wedge-shaped sliders 621. When the side limiting plate 61 is subjected to a force, it can drive the wedge-shaped sliders 621 to slide inside the wedge-shaped grooves 622, thereby restricting the movement direction of the side limiting plate 61.

[0035] Furthermore, the adjustment unit 63 includes a solenoid 631 that passes through the interiors of the two wedge-shaped sliders 621. A threaded bidirectional lead screw 632 is threaded through the interiors of the two solenoids 631. A bearing seat 633 is sleeved on the surface of the bidirectional lead screw 632 and mounted on the inner wall of the horizontal plate 22. A driven bevel gear 634 is connected to the surface of the bidirectional lead screw 632. A drive motor 635 is mounted on the inner wall of the horizontal plate 22. A driving bevel gear 636 is mounted on the output end of the drive motor 635 and meshes with the driven bevel gear 634. When the drive motor 635 operates, it can drive the driving bevel gear 636 to rotate. When the driving bevel gear 636 rotates, it can drive the driven bevel gear 634 to rotate through the meshing structure. When the driven bevel gear 634 rotates, it can drive the bidirectional lead screw 632 to rotate. When the bidirectional lead screw 632 rotates, it can drive the two solenoids 631 to move in opposite directions through the threaded connection. The reverse movement of the two solenoids 631 can drive the two side limiting plates 61 to move in opposite directions through the two wedge-shaped sliders 621.

[0036] Furthermore, the surface of the processing table assembly 2 is also symmetrically provided with end limiting assemblies 7 for limiting the two ends of the workpiece;

[0037] The end limiting assembly 7 includes two sets of movable seats 71 fitted into the inner wall of the horizontal plate 22 and symmetrically arranged, a second guide portion 72 respectively disposed between the two sets of movable seats 71 and the horizontal plate 22, limiting blocks 73 respectively connected to the surfaces of the two sets of movable seats 71, and telescopic rods 74 respectively connected to the inner walls of the movable seats 71 and installed on the surface of the horizontal plate 22. When the telescopic rods 74 are in operation, they can drive the movable seats 71 to move laterally. When the movable seats 71 move laterally, they can drive the limiting blocks 73 to move laterally, thereby adjusting the distance between the two sets of limiting blocks 73.

[0038] Furthermore, the second guide portion 72 includes guide blocks 721 respectively connected to both sides of the movable seat 71, and guide grooves 722 formed on the inner wall of the transverse plate 22 and adapted to the guide blocks 721. When the movable seat 71 is subjected to a force, it can drive the guide blocks 721 to slide inside the guide grooves 722, which can limit the direction of movement of the movable seat 71 and thus maintain the stability of the movement of the movable seat 71.

[0039] The following is a detailed explanation using the production of a watch dial as an example: In actual use, the watch dial 3 is first positioned by two sets of second positioning components 5. After the watch dial 3 is processed, the second rotary cylinder 51 can be run. When the second rotary cylinder 51 is running, it can drive the second rubber pad 53 to rotate and rise through the second pressure plate 52. When the second pressure plate 52 drives the second rubber pad 53 to rotate 90°, the first rotary cylinder 41 can be run. When the first rotary cylinder 41 is running, it can drive the first rubber pad 43 to rotate and fall through the first pressure plate 42. When the first pressure plate 42 drives the first rubber pad 43 to rotate 90°, the first pressure plate 42 drives the first rubber pad 43 to press on the surface of the watch dial 3. This can achieve the repositioning of the watch dial 3, so that the unprocessed parts of the watch dial 3 can be processed, thereby forming continuous and comprehensive processing.

[0040] When the drive motor 635 is running, it drives the active bevel gear 636 to rotate. When the active bevel gear 636 rotates, it drives the bidirectional lead screw 632 to rotate through the driven bevel gear 634. When the bidirectional lead screw 632 rotates, it drives the two wedge sliders 621 to move in the opposite direction through the two solenoids 631. The two wedge sliders 621 move in the opposite direction, which drives the two side limit plates 61 to move in the opposite direction. This makes it convenient to limit the two sides of the dial 3 of different diameters.

[0041] At the same time, when the telescopic rod 74 is running, it drives the movable seat 71 to move laterally. The lateral movement of the movable seat 71 drives the position of the adjusting limit block 73, which can limit the position of the block 73, thereby adapting to the dial 3 of different lengths for end limiting.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
