Description

Technical Field

[0001] The utility model relates to the field of machine tool processing equipment, in particular to a positioning tooling. Background Art

[0002] When processing workpieces such as plates, etc., fixtures are usually used to fix the workpieces on the machine tool, and then the machine tool is operated to process the workpieces. The fixture can keep the workpieces in the correct position and posture during the processing, ensuring the processing accuracy.

[0003] In the prior art, fixed stoppers and movable fixing blocks are usually used to clamp and fix the workpieces. The workpieces are placed on the base of the machine tool, then the workpieces are clamped into the slots of the stoppers, and finally the fixing blocks are moved until the fixing blocks abut against the workpieces. Then the worker locks the fixing blocks, completing the positioning of the workpieces on the machine tool. When locking the fixing blocks, the worker tightens the fastening bolts on the fixing blocks, driving the fastening bolts to pass through the fixing blocks and abut against the base, thereby fixing the fixing blocks firmly on the base.

[0004] For the above solution, since the fixing blocks are fixed by the friction between the fastening bolts and the base, the workpieces may be vibrated during the processing. When the vibration is conducted to the fastening bolts through the fixing blocks, it is easy to cause the fastening bolts to loosen, resulting in difficulty in maintaining the locking of the fixing blocks. Therefore, a structure for more firmly positioning the fixing blocks is needed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a positioning tooling to solve one or more technical problems existing in the prior art, and at least provide a beneficial choice or create conditions.

[0006] The solution of the utility model to solve its technical problems is as follows:

[0007] Base

[0008] Stopper, the stopper is installed on the base

[0009] First fixing block, the first fixing block can slide and be positioned on the base, and the first fixing block slides along the direction close to or away from the stopper

[0010] Connecting bar, the connecting bar is installed on the base, the connecting bar extends along the sliding direction of the first fixing block, the first fixing block slides on the connecting bar, a rack is arranged on the connecting bar, a locking block is slidably installed on the first fixing block along the direction close to or away from the rack, a driving component for driving the locking block to slide on the first fixing block is arranged on the first fixing block, and a tooth groove is opened on the locking block, and the rack meshes with the tooth groove.

[0011] The technical solution has at least the following beneficial effects: Firstly, the base provides a stable foundation for the placement of the workpiece, ensuring a reliable support plane for the workpiece during operation, which helps to maintain the stability and accuracy of the workpiece. Then, the worker places the workpiece on the support pile and drives the first fixing block to slide on the connecting bar until it abuts against the workpiece. Then, the driving component is started to drive the locking block to slide on the first fixing piece and then abut against and engage with the rack, achieving reliable locking of the first fixing block, which can be firmly fixed on the connecting bar, preventing loosening or displacement during the clamping of the workpiece, and ensuring the stability and precision of the clamping.

[0012] As a further improvement of the above technical solution, a first pressing block is slidably mounted on the support pile in the vertical direction. A pressing portion extending towards the first fixing block is provided at the top of the first pressing block. A gap for clamping the workpiece is formed between the pressing portion and the support pile. A plurality of first pressing blocks mounted on the support pile can apply pressure to the workpiece placed on the support pile from above, further enhancing the fixing effect of the workpiece in the vertical direction and preventing the workpiece from jumping upwards during processing or operation.

[0013] As a further improvement of the above technical solution, the positioning tooling further includes positioning piles. There are several positioning piles. Each positioning pile can slide and be positioned on the base. Each positioning pile slides in a plane perpendicular to the moving direction of the first fixing block. An operation area for clamping the workpiece is formed between any two positioning piles. The support pile and the first fixing block are both located in the operation area. After installing each pair of positioning piles on the base and abutting against the side of the workpiece, at this time, the first fixing block, the support pile and the positioning piles clamp the workpiece from each side, preventing it from shifting, shaking or rotating during processing or operation, thereby ensuring the processing precision and the accuracy of the operation.

[0014] As a further improvement of the above technical solution, a connecting groove is formed in the first fixing block. The connecting bar passes through the first fixing block through the connecting groove. A limiting bar is provided on the connecting bar. A limiting groove is formed at the groove wall of the connecting groove in the first fixing block. The limiting bar is slidably mounted on the first fixing block through the limiting groove. The cooperation between the limiting bar and the limiting groove restricts the displacement of the first fixing block in the vertical direction, providing an accurate and stable path limit for the sliding of the first fixing block, ensuring that the first fixing block always moves along a predetermined straight line direction during adjustment, and avoiding deviation or skew.

[0015] As a further improvement of the above technical solution, the driving component includes a locking bolt and an elastic member. The locking bolt is threadedly installed on the first fixing block, and one end of the locking bolt passing through the first fixing block abuts against the locking block. The elastic member is disposed between the locking block and the first fixing block. When the elastic member is in a natural state, the locking block slides away from the rack. By using the locking bolt as the power source for driving the locking block to move downward, its threaded installation method provides an accurate and reliable adjustment mechanism. Through a simple rotation operation, the control of the locking block can be achieved, which is convenient to operate and easy to master. The setting of the elastic member enables the locking block to be automatically driven away from the slide rail when the locking bolt is unscrewed, without additional manual operation, improving the efficiency and convenience of the tooling adjustment.

[0016] As a further improvement of the above technical solution, the first fixing block includes a fixed part and a movable part. The fixed part is installed on the connecting bar, and the movable part is slidably installed on the fixed part. A driving member for driving the movable part to slide on the fixed part is installed on the fixed part. After the movable part moves, it tightly abuts against the workpiece installed on the base table. This design of dividing the first fixing block into a fixed part and a movable part increases the flexibility and precision of the tooling for clamping the workpiece. Through the independent sliding of the movable part, fine adjustment can be made for the tiny distance between the first fixing block and the workpiece, ensuring the stable clamping of the workpiece.

[0017] As a further improvement of the above technical solution, a guiding surface is provided on the fixed part. The movable part is installed at the position of the guiding surface of the fixed part. The driving member includes an adjusting bolt. The adjusting bolt is rotatably installed on the movable part, and one end of the adjusting bolt passing through the movable part is threadedly connected to the fixed part;

[0018] By adopting the above technical solution, when the adjusting bolt is rotated, the movable part is driven to move on the fixed part along with the adjusting bolt. At the same time, under the action of the guiding surface, the movable part moves towards the workpiece to further clamp the workpiece. The guiding surface provided on the fixed part provides a clear guiding for the movement of the movable part, ensuring that the movable part can accurately approach the workpiece along a predetermined direction under the action of the adjusting bolt, improving the precision and reliability of the adjustment.

[0019] As a further improvement of the above technical solution, a guiding groove is opened on the fixed part, and a sliding bar is provided on the movable part. The sliding bar is slidably installed on the fixed part through the guiding groove. The guiding groove extending along the length direction of the slide rail on the fixed part cooperates with the sliding bar on the movable part, providing an accurate and stable path limit for the sliding of the movable part. This ensures that the movable part always moves along a predetermined straight line direction during the adjustment process, avoiding deviation or skew.

[0020] As a further improvement of the above technical solution, a second fixing block is installed on one side of the first fixing block close to the workpiece. The height of the second fixing block is less than that of the first fixing block. Clamping the workpiece with the second fixing block having a smaller height can provide a more fitting contact point for the workpiece with a smaller thickness, and avoid over-extrusion or collision damage to the workpiece caused by the excessive height of the first fixing block.

[0021] As a further improvement of the above technical solution, the rack is located at the top of the connecting bar, and the plane where the tooth blocks of the rack are located is higher than the upper surface of the connecting bar. Through this design, it effectively avoids the waste residues generated during the machining of the workpiece from directly falling onto the plane where the rack is located, significantly reduces the accumulation of waste residues on the rack, and reduces the risk of poor meshing or damage between the first rack and the second rack due to blockage of waste residues.

[0035] Embodiment 1

[0036] Refer to Figure 1 and Figure 2 , a positioning tooling, comprising:

[0037] Base 1, on which there are a number of installation grooves 11. Each installation groove 11 is arranged in parallel on the upper surface of the base 1. In each installation groove 11 of the base 1, a number of positioning blocks 12 are slidably installed along the length direction of the base 1 itself. Each positioning block 12 is used to install the corresponding positioning bolt. The positioning bolts are installed on each component of the positioning tooling and are threadedly connected to the corresponding positioning block 12, so as to fix each component of the positioning tooling on the base 1. Through the multiple installation grooves 11, each component of the positioning tooling can be installed at different positions on the base 1, enabling the positioning tooling to position workpieces of different specifications and sizes, and improving the applicability of the positioning tooling to workpieces of different specifications;

[0038] Pile support 2, which is installed on the base 1. There is a card slot on the pile support 2 for the workpiece to be inserted. A number of positioning bolts are rotatably installed on the pile support 2. The several positioning bolts are arranged along the length direction of the installation groove 11 on the pile support 2. One end of each positioning bolt passing through the pile support 2 is threadedly connected to the corresponding positioning block 12; The pile support 2 can provide a clear positioning reference for one end of the workpiece and restrict the movement of the workpiece in this direction.

[0039] First fixing block 3, which can slide and be positioned on the base 1. The first fixing block 3 slides along the direction of approaching or departing from the pile support 2, and the moving direction of the first fixing block 3 is perpendicular to the length direction of the installation groove 11. The slidable first fixing block 3 can adjust its own position on the base 1 according to the different lengths of the workpieces, so as to adapt to workpieces of different sizes, and improve the versatility of the positioning tooling.

[0040] Refer to Figure 1 and Figure 3 Moreover, the positioning tooling further includes a number of positioning piles 4. Each positioning pile 4 can slide and be positioned on the base 1 along the length direction of the installation groove 11. There is a connection hole on the positioning pile 4. The positioning bolt is rotatably installed on the positioning pile 4 through the connection hole. One end of the positioning bolt passing through the positioning pile 4 is threadedly connected to the corresponding positioning block 12, so as to fix the positioning pile 4 on the base 1.

[0041] An operation area for clamping the workpiece is formed between any two positioning piles 4. The pile support 2 and the first fixing block 3 are both located in the operation area. The workpiece is placed in the operation cavity and clamped. This clamping method can effectively fix the workpiece, prevent it from displacing, shaking or rotating during processing or operation, thus ensuring the machining accuracy and operation accuracy. At the same time, through this adjustable and all-round positioning tooling design, the production efficiency is improved, the waste products and rework caused by inaccurate workpiece positioning are reduced, and the production cost is lowered.

[0042] Refer to Figure 1 and Figure 2, on one side of the first fixing block 3 close to the pile 2, a second fixing block 31 is installed. The second fixing block 31 is fixedly connected to the first fixing block 3 by bolts. The height of the second fixing block 31 is less than that of the first fixing block 3. The second fixing block 31 can provide a more fitting contact point for workpieces with a smaller thickness, avoiding excessive extrusion or collision damage to the workpieces caused by the excessive height of the first fixing block 3. At the same time, anti-slip lines can be set on the side of the second fixing block 31 close to the workpiece, and the friction between the second fixing block 31 and the workpiece is increased through the anti-slip lines, thereby improving the clamping strength of the second fixing block 31 on the workpiece.

[0043] Refer to Figure 2 and Figure 3 , several first pressing blocks 21 are installed on the pile 2. A pressing part extending towards the first fixing block 3 is arranged at the top of the first pressing block 21. A gap for clamping the workpiece is formed between the pressing part and the pile 2.

[0044] A second pressing block 32 is installed on the first fixing block 3. A pressing groove is formed on the side facing downwards at one end of each second pressing block 32 close to the pile 2. The workpiece placed on the base 1 is clamped to the second pressing block 32 through the pressing groove.

[0045] Several cushion piles 13 are placed on the base 1. The cushion piles 13 are used to support the workpiece at the bottom of the workpiece. The first pressing block 21 and the second pressing block 32 can apply pressure to the workpiece placed on the pile 2 from above. The first pressing block 21 and the second pressing block 32 act synchronously with the cushion piles 13 to further enhance the fixing effect of the workpiece in the vertical direction. At the same time, the setting of multiple pressing blocks can make the pressure distribution more uniform, avoid excessive local stress on the workpiece resulting in deformation or damage, and ensure the integrity of the workpiece.

[0046] Further, as a preferred embodiment, each second pressing block 32 can slide and be positioned vertically on the first fixing block 3, and each first pressing block 21 can slide and be positioned vertically on the pile 2. By the slidable first pressing block 21 and second pressing block 32, workpieces with different thicknesses can be clamped, improving the applicability of the positioning tooling to workpieces with different thicknesses.

[0047] Refer to Figure 1 and Figure 4 , the positioning tooling further includes a connecting bar 5. The connecting bar 5 is installed on the base 1. The connecting bar 5 extends along the sliding direction of the first fixing block 3. A number of positioning bolts are arranged on the connecting bar 5 along the length direction perpendicular to the installation groove 11. Each positioning bolt is rotatably installed on the connecting bar 5. One end of each positioning bolt passing through the connecting bar 5 is threadedly connected to the corresponding positioning block 12 located in the installation groove 11. The connecting bar 5 is fixed to the base 1 through the positioning bolts and the positioning blocks 12.

[0048] Refer to Figure 4And Figure 5 , a rack groove is formed at the top of the connecting bar 5. A rack 51 is arranged in the rack groove of the connecting bar 5. The rack 51 is fixedly connected to the connecting bar 5 by bolts. The first fixing block 3 slides on the connecting bar 5 and the first fixing block 3 is located directly above the connecting bar 5. A connecting groove is formed at the bottom of the first fixing block 3. The connecting bar 5 passes through the first fixing block 3 through the connecting groove. A sliding groove is formed on the first fixing block 3. A locking block 34 is slidably mounted on the first fixing block 3 at the sliding groove in a direction close to or away from the rack 51. A driving assembly for driving the locking block 34 to slide on the first fixing block 3 is arranged on the first fixing block 3. A tooth groove 35 is formed on the locking block 34. When the locking block 34 slides in a direction close to the rack 51, the rack 51 meshes with the tooth groove 35, so that the locking block 34 is stably positioned on the rack 51 and further the first fixing block 3 is locked on the connecting bar 5.

[0049] The design of driving the locking block 34 to mesh with the rack 51 through the driving assembly provides a reliable and stable locking method. The meshing between the racks 51 can generate large frictional force and biting force, effectively preventing any sliding of the first fixing block 3 on the connecting bar 5 and improving the stability of the workpiece position during the processing.

[0050] Refer to Figure 6 , the driving assembly includes a locking bolt 6 and an elastic member. The locking bolt 6 is threadedly mounted on the first fixing block 3. One end of the locking bolt 6 passing through the first fixing block 3 abuts against the locking block 34. The elastic member can be a rubber block, a spring, etc. In this embodiment, the elastic member is a spring. One end of the spring is mounted on the first fixing block 3 and the other end is mounted on the locking block 34. When the elastic member is in a natural state, it drives the locking block 34 to always move away from the connecting bar 5;

[0051] When the first fixing block 3 needs to be moved, the locking bolt 6 is screwed out. At this time, the locking block 34 moves away from the connecting bar 5 under the action of the elastic member, and the racks 51 are no longer meshed. The first fixing block 3 can slide on the connecting bar 5. When the first fixing block 3 needs to be locked, the locking bolt 6 is tightened to push the locking block 34 downward to mesh the tooth groove 35 on the locking block 34 with the rack 51, realizing the locking of the first fixing block 3. This locking method has a simple structure, low cost, and is easy to maintain and replace parts. Moreover, on a production line where the workpiece specifications are frequently changed, the operator can quickly loosen or tighten the locking bolt 6 to adjust the position of the first fixing block 3, greatly shortening the tooling adjustment time.

[0052] Refer to Figure 4, the plane where the tooth blocks of the rack 51 are located is higher than the plane where the connecting bar 5 is located. Through this design, first, it can effectively prevent the waste residues generated during workpiece processing from directly falling onto the plane where the rack 51 is located, reducing the accumulation of waste residues on the rack 51 and lowering the risk of the rack 51 being clogged by waste residues and resulting in poor meshing or damage. Second, since waste residues are not easily accumulated in the area of the rack 51, workers only need to simply handle the waste residues on the surface of the connecting bar 5 when cleaning the waste residues, saving cleaning time and effort and improving the cleaning efficiency.

[0053] Refer to Figure 6 , limit strips are provided on both sides of the connecting bar 5 along its length direction, and each limit strip extends along the length direction of the connecting bar 5. The first fixing block 3 is provided with a limit groove at the groove wall of the connecting groove, and the limit strip is slidably installed on the first fixing block 3 through the limit groove. The cooperation between the limit strip and the limit groove restricts the displacement of the first fixing block 3 in the vertical direction, providing an accurate and stable path limit for the sliding of the first fixing block 3.

[0054] Refer to Figure 4 and Figure 5 , the first fixing block 3 includes a fixing part 7 and a moving part 8. The fixing part 7 is installed on the connecting bar 5, and the moving part 8 is slidably installed on the side of the fixing part 7 close to the workpiece along the length direction of the connecting bar 5. A driving member for driving the moving part 8 to slide on the fixing part 7 is installed on the fixing part 7. After the moving part 8 moves, it abuts against the workpiece installed on the base 1. A guiding surface 71 is provided on the fixing part 7, and the moving part 8 is installed at the position of the guiding surface 71;

[0055] The driving member includes an adjusting bolt 9. The moving part 8 is provided with a first connection hole 81, and the adjusting bolt 9 is rotatably installed on the moving part 8 through the first connection hole 81. The fixing part 7 is provided with a second connection hole 72, and one end of the adjusting bolt 9 passing through the moving part 8 is threadedly installed on the fixing part 7 through the second connection hole 72. After turning the adjusting bolt 9, through the cooperation of the guiding surface 71 and the adjusting bolt 9, the moving part 8 is driven to slide so as to further clamp the workpiece. In this way, fine adjustment of the moving part 8 can be realized, accurately controlling the sliding of the moving part 8. The operator can easily and accurately adjust the clamping force and position, avoiding workpiece damage or inaccurate positioning caused by improper clamping.

[0056] Refer to Figure 5 , the fixing part 7 is provided with a sealing plate 73 at the bottom of the second connection hole 72 to block the adjusting bolt 9 inserted into the fixing part 7 and prevent the adjusting bolt 9 from passing through the second connection hole 72 and contacting the rack 51 and being damaged.

[0057] The fixed part 7 is provided with a guide groove extending along the length direction of the connecting bar 5. A sliding bar is arranged on the moving part. The sliding bar is slidably installed on the fixed part 7 through the guide groove. The guide groove cooperates with the sliding bar to provide an accurate and stable path limit for the sliding of the moving part 8, ensuring that the moving part 8 always moves along a predetermined straight line direction during the adjustment process, avoiding deviation or skew, thereby improving the accuracy and reliability of the adjustment.

[0058] The implementation principle of Embodiment 1 of a positioning tooling of the present utility model is as follows: First, after the worker installs the pile support 2, the connecting bar 5, and the positioning pile 4 on the base 1, then the first fixing block 3 and the second fixing block 31 are integrally installed on the connecting bar 5. Then the workpiece is placed on the base 1 and the cushion pile 13 is used to support the workpiece. At this time, the worker starts to move the positioning pile 4 and the first fixing block 3 until the two are tightly pressed against the side of the workpiece, and the positioning bolts at each place are tightened to fix the positioning pile 4 on the base 1. Then the locking bolt 6 is tightened, and through the cooperation of the locking block 34 and the rack 51, the first fixing block 3 is fixed on the connecting bar 5 to achieve the preliminary positioning of the workpiece. After that, the worker can, according to the distance between the workpiece and the first fixing block 3, turn the adjustment bolt 9 to drive the moving part 8 to slide on the fixed part 7, thereby driving the second fixing block 31 to further press against the workpiece and improving the stability of the workpiece during machining on the base 1.

[0059] Embodiment 2

[0060] The difference from Embodiment 1 is that the driving assembly includes a driving cylinder. The driving cylinder is fixedly installed on the first fixing block 3, and the output end of the driving cylinder is fixedly connected to the side of the locking block 34 away from the rack 51. When the driving cylinder is started, it can drive the locking block 34 to move towards or away from the rack 51 at the sliding groove, so that the locking block 34 stably engages with the rack 51 after approaching the rack 51, realizing the rapid locking of the first fixing block 3.
