[0002] Machining generally requires the use of tooling fixtures to position one or more workpieces on the tooling fixtures before machining.

[0003] Existing workpiece machining fixtures, such as Figure 1 and Figure 2 As shown, several workpiece placement slots are formed on the tooling base plate to accommodate workpieces. Then, a corresponding clamping block is installed inside each workpiece placement slot to clamp the workpiece inside. However, when processing workpieces with multiple holes simultaneously, this operation method requires frequent installation and removal of the clamping blocks, which is cumbersome and inefficient.

[0004] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a multi-hole product positioning and processing tooling, which would make it more valuable for industrial use. Utility Model Content

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a multi-hole product positioning and processing tooling.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multi-hole product positioning and processing fixture includes a fixture base plate, which is mounted on a worktable by several support frames. At least one clamping block placement groove distributed along the left and right direction is provided on both the front and rear sides of the fixture base plate. Several workpiece placement grooves for accommodating workpieces are evenly provided on the outside of the clamping block placement groove along the left and right direction.

[0008] A clamping block is installed in the clamping block placement slot. A placement slot guide slope is provided on the side of the clamping block placement slot away from the workpiece placement slot. A placement slot vertical surface is provided on the side of the clamping block placement slot facing the workpiece placement slot. The clamping block guide slope on the clamping block is adapted to the placement slot guide slope, and the clamping block vertical surface on the clamping block is adapted to the placement slot vertical surface.

[0009] A sinkhole is provided below the workpiece placement slot, and an adsorption structure is installed in the sinkhole.

[0010] As a further improvement of this utility model, the four opposite corners of the tooling base plate are respectively embedded in the right-angle grooves in the support frame below, and tooling handles are installed in the middle of the left and right sides of the tooling base plate.

[0011] As a further improvement of this utility model, countersunk holes for installing clamping block locking bolts are respectively opened on the left and right sides of the clamping block, and clamping block locking holes are opened in the clamping block placement groove directly below the countersunk holes. The clamping block locking bolts located in the countersunk holes are locked together with the clamping block locking holes below.

[0012] As a further improvement of this utility model, a clearance groove is provided in the clamping block placement groove on both the left and right sides of the clamping block.

[0013] As a further improvement of this utility model, a notch is provided on the outer side of the workpiece placement groove along the front-back direction to communicate with the inner workpiece placement groove, and through grooves are provided on both the left and right sides of the tooling base plate to communicate with the inner clamping block placement groove.

[0014] As a further improvement of this utility model, a cover plate is covered on the top outer side of the tooling substrate, the cover plate is mounted on the support frame below, and a cover plate handle is installed on the cover plate.

[0015] As a further improvement of this utility model, there are two cover plates, which are located on the left and right sides of the tooling base plate respectively.

[0017] As a further improvement of this utility model, the adsorption structure is a vacuum adsorption pore.

[0018] By means of the above solution, this utility model has at least the following advantages:

[0019] This invention features a design that allows for the simultaneous clamping of workpieces located in multiple workpiece placement slots using a single clamping block. This reduces the frequency of clamping block installation and removal, making operation more convenient and improving work efficiency.

[0020] This invention utilizes an adsorption structure installed within a sinking trough to perform bottom adsorption on workpieces installed in the workpiece placement trough, thereby further improving the stability of the workpiece installation within the trough.

[0021] This invention improves the stability of the tooling substrate on the workbench by using a cover plate to press the tooling substrate together before mounting it on the support frame.

[0036] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0037] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0038] like Figures 1-2 As shown, the existing workpiece processing fixture mainly includes a fixture base plate 1, a support frame 2, and a worktable 3. Several workpiece placement slots 5 are formed on the fixture base plate 1 to accommodate workpieces 6. A corresponding clamping block 8 is installed inside each workpiece placement slot 5, and the workpiece 6 inside is clamped individually by the clamping block 8. However, this operation method requires frequent installation and removal of the clamping blocks when processing workpieces with multiple holes simultaneously, resulting in cumbersome operation and low work efficiency.

[0039] The first embodiment of this utility model:

[0040] like Figure 3As shown, the four diagonal corners of the tooling base plate 1 are respectively embedded in the right-angle slots in the support frame 2 below, thus mounting it on the worktable 3. Tooling handles 4 are installed in the middle of both the left and right sides of the tooling base plate 1. Two clamping block placement slots 7 are opened on the front and rear sides of the tooling base plate 1, distributed along the left and right direction. A long strip-shaped clamping block 8 is installed in each clamping block placement slot 7. Several workpiece placement slots 5 are evenly opened on the outer side of the clamping block 8 along the left and right direction. The workpieces 6 to be processed are sequentially installed in the workpiece placement slots 5. The clamping of a row of workpieces 6 can be completed by the two clamping blocks 8.

[0041] like Figure 5 After the workpiece 6 is installed in the workpiece placement slot 5, the top of the workpiece 6 is designed to protrude from the top of the workpiece placement slot 5. This facilitates the processing of the workpiece 6, as well as the installation and removal of the workpiece 6.

[0042] like Figure 6 and Figure 7 The mounting structure of clamping block 8 within clamping block placement slot 7:

[0043] Both the clamping block placement groove 7 and the clamping block 8 are strip-shaped structures along the left and right direction. A placement groove guide slope 16 is provided on the side of the clamping block placement groove 7 away from the workpiece placement groove 5. Correspondingly, the clamping block guide slope 20 on the clamping block 8 is adapted to the placement groove guide slope 16, thereby playing a certain auxiliary positioning function for the installation of the clamping block 8 in the clamping block placement groove 7.

[0044] A vertical surface 17 for the placement groove is provided on the side of the clamping block placement groove 7 facing the workpiece placement groove 5. Correspondingly, the vertical surface 21 of the clamping block 8 is adapted to the vertical surface 17 of the placement groove. The vertical surface 21 of the clamping block is used to contact the workpiece 6 on one side, thereby realizing the clamping process of the workpiece 6.

[0045] When the clamping block 8 is placed in the clamping block placement groove 7, the clamping block locking bolt 10 located in the countersunk hole 9 is locked together with the clamping block locking hole 18 below, thereby locking the clamping block 8 more stably in the clamping block placement groove 7.

[0046] Furthermore, to facilitate the installation and removal of the clamping block 8, it can also be made of iron, with an electromagnet installed at the bottom of the clamping block placement slot 7. When the clamping block 8 is installed in the clamping block placement slot 7, the electromagnet is energized to attract the clamping block 8, thus improving the installation stability of the clamping block 8. When the clamping block 8 needs to be removed from the clamping block placement slot 7, the electromagnet is de-energized, making it easy for the clamping block 8 to be removed from the clamping block placement slot 7.

[0047] like Figure 6 The positioning structure of workpiece 6 within workpiece placement slot 5:

[0048] The workpiece 6 is placed in the workpiece placement groove 5. A recessed groove 14 is provided at the bottom of the workpiece placement groove 5. An adsorption structure 15 for adsorbing the workpiece 6 is installed in the recessed groove 14. The adsorption structure 15 is a vacuum adsorption hole. The vacuum adsorption hole can be connected to an external air source mechanism through an air pipe to achieve adsorption of the workpiece 6.

[0049] The adsorption structure 15 installed in the sink trough 14 can perform bottom adsorption treatment on the workpiece 6 installed in the workpiece placement trough 5, which further improves the firmness of the workpiece 6 in the workpiece placement trough 5.

[0050] In order to avoid the clamping block placement groove 7 being too narrow and causing inconvenience when installing and disassembling the clamping block 8, a clearance groove 11 is provided in the clamping block placement groove 7 on both the left and right sides of the clamping block 8. The existence of the clearance groove 11 makes the clamping block 8 and the two sides of the clamping block placement groove 7 have a certain gap, which facilitates the installation and disassembly of the clamping block 8 in the clamping block placement groove 7.

[0051] like Figure 5 and Figure 6 A notch 13 is provided on the outer side of the workpiece placement groove 5 along the front-back direction, communicating with the inner workpiece placement groove 5. Through grooves 19 are provided on both the left and right sides of the tooling base plate 1, communicating with the inner clamping block placement groove 7. When the installed workpiece 6 is blown cleaned by an external air-blowing cleaning mechanism, the design of the notch 13 and through grooves 19 facilitates the blowing out of dust or waste materials from the tooling base plate 1.

[0052] The second embodiment of this utility model:

[0053] like Figure 4 As shown, the four opposite corners of the tooling base plate 1 are respectively embedded in the right-angle slots in the support frame 2 below, and thus installed on the worktable 3. A clamping block placement slot 7 is opened on both the front and rear sides of the tooling base plate 1, which are distributed in the left and right direction. A long strip-shaped clamping block 8 is installed in the clamping block placement slot 7. Several workpiece placement slots 5 are evenly opened on the outside of the clamping block 8 in the left and right direction. The workpieces 6 to be processed are installed in the workpiece placement slots 5 in sequence. A row of workpieces 6 can be clamped by one clamping block 8.

[0054] The third embodiment of this utility model:

[0055] A cover plate 22 is covered on the top outer side of the tooling base plate 1. The cover plate 22 is mounted on the support frame 2 below, and a cover plate handle 23 is installed on the cover plate 22 to facilitate the removal of the cover plate 22.

[0056] like Figure 8There are two cover plates 22 distributed along the front and back direction, located on the left and right sides of the tooling base plate 1 respectively. When it is necessary to lock the cover plates 22, the cover plates 22 are locked together with the cover plate locking holes 12 on the support frame 2 by cover plate locking bolts 24 on the front and back sides respectively.

[0057] The fourth embodiment of this utility model:

[0058] A cover plate 22 is covered on the top outer side of the tooling base plate 1. The cover plate 22 is mounted on the support frame 2 below, and a cover plate handle 23 is installed on the cover plate 22 to facilitate the removal of the cover plate 22.

[0059] like Figure 9 There is one cover plate 22. The cover plate 22 is a hollow frame structure. When the cover plate 22 needs to be locked, it is locked together with the cover plate locking holes 12 on the support frame 2 by cover plate locking bolts 24 at the four opposite corners of the cover plate 22.

[0060] The structural design of pressing the tooling substrate with the cover plate in the third and fourth embodiments and then installing it on the support frame further improves the firmness of the tooling substrate on the workbench.
