Description

Technical Field

[0001] This utility model relates to the field of non-standard tooling technology, and in particular to a general-purpose tooling for subtractive processing. Background Technology

[0002] Subtractive processing refers to the processing method of removing excess material from a semi-finished product, such as cutting and milling. Before performing subtractive processing on a product, it is necessary to fully position the product to prevent risks such as displacement and tool vibration during processing.

[0003] For small parts, limiting the position is relatively easy, but for large three-dimensional frame products, especially parts with long rods, the vibrating knife poses a high risk and is difficult to operate. Utility Model Content

[0004] In response to the shortcomings of the existing production technologies, the applicant provides a reasonably structured universal tooling for subtractive processing, suitable for subtractive processing of large-size frame products.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A general-purpose tooling for subtractive manufacturing includes a base plate, on which several sets of equal-height limiting components are mounted. Each set of limiting components includes:

[0007] The support unit is mounted on the base plate.

[0008] The support surface is the top surface of the support unit, and all support surfaces are coplanar.

[0009] The clamping part is located on the top side wall of the support part.

[0010] The fixture is used to clamp workpieces that are placed upright or upside down. When the workpiece is clamped upright, the clamping part limits the rods of the workpiece. When the workpiece is clamped upside down, the supporting surface abuts against the bottom surface of the workpiece and clamps the rods of the workpiece.

[0011] As a further improvement to the above technical solution:

[0012] Extension plates are installed on both sides of the support surface. The extension plates are coplanar with the support surface and extend beyond the top corner of the support surface. The clamping part is located on the extension plate.

[0013] The extension plate and the clamping part, as well as the extension plate and the supporting surface, are both detachable structures.

[0014] At least one support surface is provided with a pressure block, which is located above the support surface and applies pressure toward the support surface to the workpiece to be processed.

[0015] Height compensation components are installed on the support surface.

[0016] The limiting component is a pre-installed modular component, and the limiting component is detachably or slidingly connected to the base plate.

[0017] All limit components in the same tooling have the same structure.

[0018] In the same tooling, the limit components are only installed horizontally or vertically.

[0019] The base plate is equipped with multi-directional side top screws.

[0020] The beneficial effects of this utility model are as follows:

[0021] The advantage of this utility model is that it can be used for subtractive processing after welding of large-size frame products. It is suitable for processing and limiting the workpiece in both upright and inverted states. Since the entire tooling consists of only a base plate, modular limiting components, and side top screws that can be detachably installed on the base plate, the overall structure is simple and the production cost is low.

[0028] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0029] like Figures 1-4 As shown, the general-purpose tooling for subtractive processing in this embodiment includes a base plate 1, on which several sets of equal-height limiting components 2 are installed. Each set of limiting components 2 includes:

[0030] Support 201 is installed on base plate 1.

[0031] Support surface 202 is the top surface of support part 201, and all support surfaces 202 are coplanar.

[0032] The clamping part 203 is located on the top side wall of the support part 201.

[0033] The tooling is used to clamp the workpiece to be processed, whether it is upright or upside down. When the workpiece is upright, the clamping part 203 limits the rod of the workpiece. When the workpiece is upside down, the supporting surface 202 abuts against the bottom surface of the workpiece and clamps the rod of the workpiece.

[0034] Extension plates 204 are installed on both sides of the support surface 202. The extension plates 204 are coplanar with the support surface 202 and extend beyond the top corner of the support surface 202. The clamping part 203 is located on the extension plate 204.

[0035] The extension plate 204 and the clamping part 203, as well as the extension plate 204 and the support surface 202, are both detachable structures.

[0036] At least one support surface 202 is provided with a pressure block 205, which is located above the support surface 202 and applies pressure toward the support surface 202 to the workpiece to be processed.

[0037] A height compensation component 206 is provided on the support surface 202.

[0038] The limiting component 2 is a pre-installed module component, and the limiting component 2 and the base plate 1 are detachably connected or slidably connected.

[0039] All limit components 2 in the same tooling have the same structure.

[0040] In the same fixture, the limit component 2 is installed either horizontally or vertically.

[0041] The base plate 1 is equipped with multi-directional side top screws 207.

[0042] The specific structure and usage of this utility model are as follows:

[0043] The design concept of this utility model is to set multiple sets of modular pre-installed limiting components 2 with the same structure in the xy direction on the base plate 1.

[0044] Each set of limiting components 2 has the same structure, including a support part 201, which is a frame structure made of steel profiles. To improve strength, ribs are added to the sides of the support part 201. The top of the support part 201 has a support surface 202 parallel to the base plate 1. Extension plates 204 are installed on two opposite sidewalls of the support surface 202, meaning each support surface 202 has a set of two extension plates 204. Clamping parts 203 are installed opposite each other on the two side extension plates 204. All support parts 201 are of equal height, and all support surfaces 202 are coplanar. Setting all support surfaces 202 to the same height is suitable for inverting non-standard frame products with a bottom surface. When inverted, the non-standard frame product, as the workpiece to be processed, has its bottom surface flat on the support surface 202 and is supported by multiple points of force from the support surfaces 202. Side-mounted screws 207 installed on the base plate 1 can limit the rod portion of the workpiece to be processed. When the workpiece is relatively large, its bottom surface is flat on the support surface, and there is still a gap between the workpiece and the support surface, a height compensation component 206 is installed on the support surface to compensate for the height difference. The height compensation component can be a threaded rod, which can be adjusted by rotating it, so as not to affect the upright limit while meeting the limit requirements in the inverted state.

[0045] In this embodiment, for ease of description, the side of the limiting component 2 where the clamping part 203 is located is referred to as the front side.

[0046] The clamping function of the clamping part 203 is achieved by a screw that passes through the extension plate 204. The screw rotates to adjust the size of the intermediate clamping space, thereby clamping the component.

[0047] To accommodate workpieces of various sizes and apply clamping forces in different directions, in this embodiment, some of the front faces of the limiting components 2 face the positive x-direction, some face the opposite x-direction, some face the positive y-direction, and some face the opposite y-direction. Combined with the detachable or sliding connection structure between the limiting components 2 and the base plate 1 in this embodiment, it can be applied to limiting workpieces of various sizes.

[0048] The detachable connection method can use fastener connection, where the pre-installed limiting component 2 module is installed on the base plate 1 using screws or other fasteners; the sliding connection method is only used for contours where the size changes but the shape remains the same, where the bottom of the limiting component 2 is embedded in the base plate 1 and the sliding method is adjusted, and after sliding to the designated position, the fastener is used to lock the installation.

[0049] At the location where pressing is required, a pressure block 205 is also provided. The pressure block 205 is connected to the tooling and applies a downward pressing force to the workpiece to be processed.

[0050] The advantage of this utility model is that it is applicable to the processing limit in both upright and inverted states of the workpiece to be processed. Since the entire tooling consists of only a base plate 1, a modular limit component 2, and a side top screw 207 that can be detachably installed on the base plate 1, the overall structure is simple and the production cost is low.

[0051] In order to improve the limiting strength and reduce the installation difficulty, all limiting components 2 have only two directions, x and y, on the front. If the product has a bevel, the limiting component 2 will abut against and limit the straight edge adjacent to the bevel, thereby reducing the alignment difficulty.

[0052] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
