Description

Technical Field

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

[0002] For machining large frame products, the structural characteristics of the product itself need to be considered. For example, if the product has a frame section and a long rod section, the long rod section is less stable. During the subtractive machining process after welding, the long rod is prone to wobbling when the cutting tool contacts the surface of the long rod, causing machining deviations. Currently, in the industry, the machining of large frame products mostly uses small fixtures combined with manual climbing for machining. This method is labor-intensive, but the accuracy of the finished product is still relatively low. Utility Model Content

[0003] In response to the shortcomings of the existing production technology, the applicant provides a reasonably structured tooling for post-weld subtractive processing, which is particularly suitable for subtractive processing of large enclosure products. It uses a combination of bottom support and top clamping to prevent vibration of the blade.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A post-weld subtractive processing fixture includes a base plate, capable of processing workpieces placed upright and those placed upside down; several positioning frames are mounted on the base plate, and each positioning frame has a clamping assembly at its top.

[0006] The clamping assembly includes:

[0007] The reference block is installed on the top surface of the positioning frame.

[0008] The pad is installed between the reference block and the positioning frame bracket.

[0009] The locking rod passes through the reference block and is threadedly connected to the reference block.

[0010] The clamping assemblies are arranged in groups, and each group of clamping assemblies has at least two opposing locking rods.

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

[0012] The positioning frame includes a single frame and a continuous frame, with the single frame set at intervals along a straight line or arc.

[0013] The base plate is also equipped with abutment blocks, and each abutment block is equipped with a locking rod.

[0014] The contact block is set on the outside of the workpiece to be processed.

[0015] All clamping components are set along the contour of the workpiece.

[0016] The clamping force applied to the workpiece by the clamping assembly is perpendicular to the force-bearing surface.

[0017] Clamping components on the same positioning frame are grouped together, and the clamping forces applied by the same group of clamping components are located in the same horizontal plane.

[0018] The clamping components and the positioning frame are detachably connected.

[0019] The beneficial effects of this utility model are as follows:

[0020] This utility model sets the clamping structure on the top of the tooling, and uses a limiting contour composed of multiple positioning frames at the bottom of the tooling to clamp the bottom of the frame product against and the end of the long rod at the top. The height of the positioning frames provides support for the long rod part of the frame product, so that the entire frame product to be processed is reliably positioned. In particular, the long rod part is supported and limited, which can effectively prevent the occurrence of vibration. Attached Figure Description

[0032] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0033] like Figures 1-8 As shown, the post-weld subtractive processing fixture of this embodiment includes a base plate, which has the function of processing workpieces placed upright and workpieces placed upside down; a plurality of positioning frames 1 are installed on the base plate, and a clamping component 2 is provided on the top of each positioning frame 1.

[0034] Clamping component 2 includes:

[0035] Reference block 201 is installed on the top surface of positioning frame 1.

[0036] Pad 202 is installed on the bracket between the reference block 201 and the positioning frame 1.

[0037] The locking rod 203 passes through the reference block 201 and is threadedly connected to the reference block 201.

[0038] The clamping components 2 are arranged in groups, and each group of clamping components 2 has at least two opposing locking rods 203.

[0039] The positioning frame 1 includes a single frame 101 and a continuous frame 102. The single frame 101 is set at intervals along a straight line or arc.

[0040] The base plate is also provided with abutment blocks 3, and each abutment block 3 is provided with a locking rod 203.

[0041] The contact block 3 is located on the outside of the workpiece to be processed.

[0042] All clamping components 2 are set along the contour of the workpiece to be processed.

[0043] The clamping force applied to the workpiece by the clamping assembly 2 is perpendicular to the force-bearing surface.

[0044] The clamping components 2 on the same positioning frame 1 are a group, and the clamping force applied by the same group of clamping components 2 is located in the same horizontal plane.

[0045] The clamping component 2 and the positioning frame 1 are detachably connected.

[0046] The specific structure of this utility model is as follows:

[0047] like Figure 1 and Figure 2As shown, this is a type of frame product targeted by this utility model, which will be referred to as "workpiece" below for ease of expression. After welding, this workpiece needs to undergo material reduction processing. This utility model provides a tooling specifically for this type of large workpiece with long rod parts.

[0048] like Figure 3 The diagram shows the overall structure of the tooling. The tooling includes a base plate. On the base plate, according to the shape of the workpiece to be processed, two sets of single frames 101 and one set of continuous frames 102 are installed. The continuous frames 102 correspond to the straight edge contour of the workpiece to be processed, and the single frames 101 correspond to the semi-circular contour of the multiple plates of the workpiece to be processed.

[0049] Combination Figure 3 and Figure 4 There are three sets of clamping components 2 installed on the top of the continuous frame 102, according to... Figure 1 The orientation of the components, from left to right, is as follows: a group with two clamping components 2, a group with three clamping components 2, and a group with two clamping components 2. The clamping component groups 2 located at both ends are used to clamp the ends of a single long rod, thus the two clamping components 2 can effectively limit the movement of the long rod. For example... Figure 5 and Figure 7 , Figure 8 As shown, three clamping components 2 are needed in the middle position to clamp and limit the three edges of the slightly larger plate.

[0050] like Figure 4 As shown, each of the two single-frame sets 101 has a set of two clamping components 2 at its top to clamp the top end of the long rod. In this embodiment, in order to conform to the shape of the workpiece, the two single-frame sets 101 are placed at an angle, so that the locking rod 203 at the top of the single-frame set 101 is vertically aligned with the side wall of the long rod of the workpiece. In the same set of clamping components 2, the two opposing locking rods 203 are arranged collinearly.

[0051] Another advantage of this utility model is that it can... Figure 1 The parts to be processed in the process of Figure 1 Orientation, that is, processing is carried out when the workpiece is placed upright, or the workpiece to be processed can be arranged according to... Figure 2 The components are placed upside down on a tooling fixture for processing.

[0052] according to Figure 1 When the workpiece is placed upright, the bottom frame of the workpiece is limited by the positioning frame 1 and the abutment block 3. Figure 6 As shown, the locking rod 203 on the abutment block 3 rotates to adjust the clamping force. The long rod and plate at the top of the workpiece are limited by the clamping assembly 2, and the clamping height of the clamping assembly 2 can be adjusted by the shims.

[0053] according to Figure 2 When the workpiece is placed upside down, depending on the actual needs, if the bottom frame of the workpiece will not interfere with the clamping component 2, then the workpiece can be placed upside down on the fixture directly. If the bottom frame of the workpiece will interfere with the clamping component 2, then the interfering clamping component 2 should be disassembled, and the workpiece should be placed upside down on the fixture. In this case, the positioning frame 1 provides support for the bottom frame of the workpiece, and the remaining clamping component 2 is used to press against the side wall of the workpiece to limit its position. Alternatively, clamping component 2 can be added to the base plate as needed to limit the bottom end of the long rod.

[0054] In this embodiment, all clamping components 2 are detachable structures fastened to the positioning frame 1, and all positioning frames 1 are also detachably connected to the base plate, in order to facilitate the loading and unloading of large workpieces to be processed.

[0055] 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.
