[0045] The embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below are examples for explaining the present application and are not intended to limit the present application.

[0046] In this document, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. The terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.

[0047] As described in the background, the conventional tooling fixture structure, due to its relatively fixed design, lacks sufficient flexibility and is difficult to adapt to the actual machined parts. This fixed structure greatly reduces the applicability of the tooling fixture and cannot effectively meet the diversified and complex processing requirements in modern manufacturing.

[0048] Embodiment 1:

[0049] Therefore, in order to solve the above technical problems existing in the prior art and improve the flexibility of clamping, the present embodiment proposes a composite flexible fixture, as shown in Figure 1 The fixture comprises:

[0050] a base 10, which can be fixed on the workbench of the equipment, as shown in Figure 2 The upper surface of the base is provided with a sliding groove 12 extending linearly through the entire base;

[0051] The fixing seat 50 matches the slide groove and is removably and fixedly connected to the base, such as... Figure 7 As shown, a threaded hole 51 is provided on the side of the fixed seat 50, which passes through the fixed seat. When the fixed seat is installed in the large sliding groove, the axis of the threaded hole is parallel to the extension direction of the sliding groove.

[0052] Adjusting screw 40, such as Figure 8 As shown, the adjusting screw has a threaded portion 41 that matches the threaded hole;

[0053] First positioning block 20, such as Figure 2 As shown, the first positioning block includes a limiting block 22, and a slider 21 that matches the slide groove is integrally provided at the bottom of the limiting block. The slider and the slide groove maintain relative sliding or relative fixation. The first positioning block is removably rotatably connected to the adjusting screw.

[0054] For example, such as Figure 2 As shown, a connecting hole 13 is provided at the bottom of the groove of the base, which passes through the base. Bolts or screws are used to pass through the connecting hole from top to bottom to fix it to the worktable of the equipment.

[0055] For example, such as Figure 8 As shown, one end of the threaded portion has a connecting portion 42, and the other end of the threaded portion is a hexagonal head, the size of which is smaller than the size of the threaded portion;

[0056] like Figure 3 As shown, the end face of the first positioning block has a connecting groove 24 that matches the connecting part. When the connecting part is connected with the connecting groove, the adjusting screw and the first positioning block rotate relative to each other.

[0057] For example, such as Figure 8 As shown, the connecting part has a T-shaped cross-section;

[0058] like Figure 4 As shown, the connecting groove includes:

[0059] Slot 24A, the slot for the connection part to enter and exit;

[0063] As shown in Figure 5 , the first positioning block end face has a stepped hole through the entire first positioning block.

[0064] The first positioning block and the fixed seat are connected by matching the adjusting screw through the stepped hole with the threaded hole of the fixed seat.

[0065] As shown in Figure 2 , the base side is provided with a first positioning hole 11, and the side provided with the first positioning hole is parallel to the extension direction of the sliding groove, and the first positioning hole corresponds to the sliding groove and communicates with the sliding groove.

[0066] The second positioning hole 25 and / or the first positioning groove 26 are provided on the side of the sliding block corresponding to the first positioning hole.

[0067] By matching the second positioning hole and / or the first positioning groove with the first positioning hole at different positions, and then passing the screw from the outside to the inside through the first positioning hole, the second positioning hole (or the first positioning groove) in turn, and by matching the screw with the first positioning hole, the relative fixation of the sliding block and the sliding groove is achieved.

[0068] As shown in Figure 7 , the third positioning hole 52 and / or the second positioning groove 53 are provided on the side of the fixed seat corresponding to the first positioning hole.

[0069] By matching the third positioning hole and / or the second positioning groove with the first positioning hole at different positions, and then passing the screw from the outside to the inside through the first positioning hole, the third positioning hole (or the second positioning groove) in turn, and by matching the screw with the first positioning hole, the relative fixation of the fixed seat and the sliding groove is achieved.

[0070] As shown in Figure 2 , the sliding groove can be a T-shaped groove, and as shown in Figure 3 , the sliding block can be a T-shaped block.

[0071] In this embodiment, in addition to the above-mentioned T-shaped block matching T-shaped groove mode to achieve the sliding cooperation of the sliding block and the sliding groove or the fixed seat and the sliding groove, the connection mode of I-shaped block and I-shaped groove can also be used.

[0072] As shown in Figure 2 , the clamp can further include a second positioning block 30, which is removably installed on the upper surface of the first positioning block, and as shown in Figure 6 , the upper surface of the second positioning block has an upwardly protruding support table 33, and a clamping block 34 is provided on the support table.
