Description

Technical Field

[0001] The utility model belongs to the technical field of tooling fixtures, and particularly relates to a positioning tooling. Background Art

[0002] For the manufacturing industry, positioning tooling is an indispensable component in the production and processing process. Different products must be matched with corresponding positioning tooling before the corresponding processing work can be carried out. However, it is precisely for this reason that when the products processed by the production line need to change or when a device is required to process multiple products at the same time, different types of positioning tooling must be constantly replaced. Specifically, the positioning tooling needs to be connected to the processing equipment before it can be further used to fix the product to be processed, and it is usually necessary to loosen and tighten multiple threaded parts before the positioning tooling and the processing equipment can be disassembled and assembled, so as to ensure the stability of the product during processing. This not only fails to improve the overall production and processing efficiency, but also increases the cost of manufacturing positioning tooling. Therefore, some staff will abandon the positioning work during the processing process in pursuit of efficiency; although this processing method will improve efficiency, it will come at the cost of product quality, and may even threaten the personal safety of staff due to unreliable product positioning.

[0033] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0034] The most critical concept of the utility model is that by coordinating the limiting member with the processing equipment, the fixing work of the positioning tool can be quickly completed through a small number of locking members; then the workpiece is pre-positioned in the positioning cavity to prevent the workpiece from deviating; then the driving component drives the second clamping member to move toward the first clamping member until the workpiece is clamped between the two clamping members, thereby automatically, efficiently and smoothly completing the clamping work of the workpiece.

[0035] Please refer to Figure 1 to Figure 2 The positioning tool provided by the utility model comprises a support plate 1, and a stopper 11 is provided on one side of the support plate 1 in the thickness direction;

[0036] The other side of the support plate 1 in the thickness direction is provided with a positioning cavity 2, a driving assembly 3, and a first clamping member 4 and a second clamping member 5 which are arranged opposite to each other;

[0037] The positioning cavity 2 is arranged between the first clamping member 4 and the second clamping member 5;

[0038] The driving assembly 3 can drive the second clamping member 5 to move closer to or away from the first clamping member 4 .

[0039] Specifically, the first clamping member 4 and the second clamping member 5 can be replaced with each other, and as long as any clamping member can approach the other clamping member under the drive of the driving member, the workpiece can be clamped. At the same time, the two clamping members can clamp the workpiece in a way that one is fixed and the other is movable, or in a way that both clamping members can move relative to each other.

[0040] From the above description, it can be seen that the beneficial effects of the utility model are: providing a positioning tool, matching the limit member 11 with the limit hole or limit groove on the working surface of the processing equipment, and then quickly completing the fixing work of the positioning tool through a small number of locking members; then pre-positioning the workpiece in the positioning cavity 2 to prevent the workpiece from running off the track; then the driving component 3 drives the second clamping member 5 to move toward the first clamping member 4 until the workpiece is clamped between the two clamping members; compared with the existing positioning tool, it not only simplifies the connection method between the positioning tool body and the processing equipment, but also can be replaced by fully automatic mechanical equipment instead of manual clamping, so that the clamping work of the workpiece can be completed smoothly, efficiently and accurately; at the same time, because the gap between the first clamping member 4 and the second clamping member 5 is adjustable, it is possible to achieve positioning and clamping of various workpieces without changing the positioning tool.

[0041] Furthermore, a plurality of avoidance holes 21 are provided at the bottom of the positioning cavity 2 .

[0042] Specifically, the size of the positioning cavity 2, the number of the avoidance holes 21, the shape of the avoidance holes 21 and the positions of the avoidance holes 21 can be freely adjusted according to the actual structure of the workpiece to be processed.

[0043] Furthermore, along the direction from the cavity opening to the cavity bottom of the positioning cavity 2 , the side wall of the positioning cavity 2 gradually shrinks toward the inside of the positioning cavity 2 .

[0044] From the above description, it can be seen that the design has made specific improvements to the structure of the positioning cavity 2. Since the outer surface of the workpiece to be processed is usually provided with various protruding structures, an avoidance hole 21 is set at the bottom of the positioning cavity 2, so that the protruding structure of the workpiece can be embedded in the avoidance hole 21, so that the workpiece to be processed can better fit with the positioning cavity 2, thereby improving the stability of positioning; and compared with the traditional positioning method of snap clamping, since the clamping of the workpiece can be completed by the first clamping member 4 and the second clamping member 5, the snap structure is cancelled, and the side wall of the positioning cavity 2 is gradually contracted from the cavity mouth to the cavity bottom of the positioning cavity 2 to the inside of the positioning cavity 2, which can facilitate the disassembly and assembly of the workpiece, and thus can effectively improve the overall processing efficiency.

[0045] Furthermore, two first notches 22 are provided on the side wall of the positioning cavity 2;

[0046] The two first notches 22 are arranged opposite to each other on both sides of the moving direction of the driving assembly 3 .

[0047] It can be seen from the above description that after the workpiece is processed, the first notch 22 can facilitate the staff to better remove the workpiece, thereby indirectly improving the disassembly efficiency of the workpiece.

[0048] Furthermore, a second notch 23 is provided on the side wall of the positioning cavity 2 , and the second notch 23 is arranged close to the first clamping member 4 .

[0049] Furthermore, the positioning tool mentioned above further includes a cushion block 6;

[0050] The first clamping member 4 is connected to the support plate 1 through a pad 6;

[0051] The clamping end of the first clamping member 4 is arranged opposite to the second notch 23 .

[0052] From the above description, it can be seen that for some workpieces with different thicknesses or with a protruding structure at one end, by changing the thickness of the pad 6 and allowing the protruding structure of the workpiece to extend to the outside of the positioning cavity 2 through the second notch 23, the first clamping member 4 can be effectively adapted to workpieces of different shapes, thereby improving the positioning stability of the workpiece.

[0053] Furthermore, the first clamping member 4 and the second clamping member 5 are respectively provided with a first limiting protrusion 41 and a second limiting protrusion 51;

[0054] The first limiting protrusion 41 and the second limiting protrusion 51 are arranged opposite to each other;

[0055] The limiting surface of the first limiting protrusion 41 and the limiting surface of the second limiting protrusion 51 are both arranged opposite to the cavity bottom of the positioning cavity 2 .

[0056] From the above description, it can be seen that the design has made specific improvements to the structure of the first clamping member 4 and the second clamping member 5, ensuring that the limiting surface of the first limiting protrusion 41 and the limiting surface of the second limiting protrusion 51 are both arranged relative to the bottom of the positioning cavity 2. That is, after the workpiece and the positioning cavity 2 are initially positioned, the workpiece can be further fastened inside the positioning cavity 2 by the first clamping member 4 and the second clamping member 5 to ensure the positioning stability of the workpiece.

[0057] Further, the driving assembly 3 includes a driving device 31, a slider 32 and a guide member 33;

[0058] The second clamping member 5 is connected to the movable end of the driving device 31;

[0059] The second clamping member 5 is slidably connected to the guide member 33 via the slider 32 .

[0060] Specifically, the driving device 31 is any commercially available device that can drive an object to move in a straight line, such as an oil cylinder, an air cylinder or a pneumatic guide rail.

[0061] From the above description, it can be seen that the design has made specific improvements to the composition structure of the driving component 3 and the positional relationship between the second clamping member 5 and the driving component 3. The driving device 31 can provide a power source for the movement of the second clamping member 5, and through the cooperation of the slider 32 and the guide member 33, it can guide the movement of the second clamping member 5, thereby avoiding the deviation of the clamping accuracy of the workpiece due to the offset of the second clamping member 5 during the movement.

[0062] The positioning tool of the utility model can assist the positioning work of the workpiece before processing.

[0067] The working principle of the utility model is as follows: first, the limiting member 11 on the support plate 1 is matched with the limiting hole or limiting groove on the working table of the processing equipment, and then the positioning tool is locked to the processing equipment through the locking member; then the workpiece is pre-positioned in the positioning cavity 2, and the driving component 3 is started, and the driving component 3 drives the second clamping member 5 to move toward the first clamping member 4 until the workpiece is clamped between the two clamping members, and the positioning of the workpiece is completed.
