[0002] Workpiece processing refers to the process of transforming raw materials into finished or semi-finished products with specific shapes, sizes and surface qualities through various mechanical operations and technological methods.

[0003] When machining a workpiece, in addition to the machining equipment, a fixing device is also needed to ensure the workpiece is securely fixed. With technological advancements, modern workpiece machining increasingly emphasizes the dimensional and shape accuracy of the finished workpiece. To ensure this accuracy, not only are precision machining equipment required, but the requirements for the fixing device are also becoming increasingly stringent. The fixing device must ensure the workpiece is securely fixed during the machining process, thereby guaranteeing the high quality and consistency of the final product. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a fixing device for workpiece processing. By setting longitudinal fixing units and transverse fixing units on the fixing frame, the workpiece is fixed longitudinally and transversely. A fixing space that fits the outer contour of the workpiece is formed between the clamping block, the fixing block, the first clamping block and the second clamping block, ensuring that the workpiece can maintain a high degree of stability throughout the processing, avoiding displacement problems caused by improper fixing, thereby ensuring the high quality and consistency of the final product.

[0005] The technical solution adopted by this utility model to solve its technical problem is to propose a fixing device for workpiece processing, comprising:

[0006] Fixed frame;

[0007] A longitudinal fixing unit is disposed on the fixing frame and has a fixing block and a clamping block. The clamping block is movably disposed above the fixing block. The fixing block is used to provide support for the workpiece. The clamping block movably abuts against one side of the workpiece in the vertical direction to fix the workpiece in the vertical direction.

[0008] A lateral fixing unit is disposed on the fixing frame and has a first clamping block and a second clamping block. The first clamping block and the second clamping block respectively move against the two sides of the workpiece in the horizontal direction to provide horizontal fixing for the workpiece.

[0009] A fixing space is formed between the longitudinal fixing unit and the transverse fixing unit. The fixing space is adapted to the outer contour of the workpiece. The fixing space can fit against the outer surface of the workpiece because the workpiece is fixed on the fixing frame, thereby increasing the contact area between the fixing device and the workpiece.

[0010] In the aforementioned fixing device for workpiece processing, the longitudinal fixing unit further includes a first driving member, the output end of which is provided with a movable seat, and the abutment block is connected to the movable seat. The first driving member drives the abutment block to move in the vertical direction through the movable seat.

[0011] In the aforementioned workpiece fixing device, the lateral fixing unit further includes a second driving member, the first clamping block is connected to the output end of the second driving member, and the second driving member is used to drive the first clamping block to move in the horizontal direction.

[0012] In the aforementioned fixing device for workpiece processing, the transverse fixing unit further includes a third driving member, the second clamping block is connected to the output end of the third driving member, and the third driving member is used to drive the second clamping block to move in the horizontal direction.

[0013] In the above-mentioned fixing device for workpiece processing, a first tooth structure is provided on one side surface of the fixing block. The first tooth structure can abut against the surface of the workpiece when the workpiece is placed on the fixing block, thereby increasing the friction between the fixing block and the workpiece.

[0014] In the aforementioned fixing device for workpiece processing, a second convex tooth structure is provided on one side surface of the abutting block. The second convex tooth structure can abut against the surface of the workpiece by moving the abutting block against one side of the workpiece in the vertical direction, thereby increasing the friction between the abutting block and the workpiece.

[0015] In the aforementioned fixing device for workpiece processing, the fixing block is further provided with a positioning groove, the workpiece abuts against the positioning groove, and the positioning groove is used to position the workpiece.

[0016] In the aforementioned fixing device for workpiece processing, the movable seat is provided with an outwardly extending protrusion, the fixing frame is provided with a guide groove, and the protrusion is movably inserted into the guide groove.

[0017] In the aforementioned fixing device for workpiece processing, the fixing frame is detachably connected to oppositely arranged support blocks, and the guide groove is formed between the two support blocks.

[0018] In the aforementioned fixing device for workpiece processing, a rotating component is provided on one side of the abutment block. The rotating component can rotate due to contact with the workpiece.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The fixing block and the clamping block in the longitudinal fixing unit and the first clamping block and the second clamping block in the transverse fixing unit can firmly fix the workpiece in the vertical and horizontal directions and form a fixed space that fits the outer contour of the workpiece, ensuring that the workpiece can maintain high stability throughout the entire processing process, avoiding displacement problems caused by improper fixing, thereby ensuring the high quality and consistency of the final product.

[0021] (2) The first tooth structure on the fixing block increases the friction between the fixing block and the workpiece, and the second tooth structure on the clamping block increases the friction between the clamping block and the workpiece, thereby enhancing the overall fixing effect of the fixing device on the workpiece in this solution.

[0022] (3) The clamping block is connected to the movable seat, which has an outwardly extending protrusion. The fixed frame is detachably connected to the oppositely arranged support block. A guide groove is formed between the two support blocks for the protrusion to be inserted. Through the cooperation of the protrusion and the guide groove, not only is the movement of the movable seat and the clamping block guided, but the movable seat and the clamping block are also effectively prevented from being displaced due to force during the processing, ensuring the structural stability, thereby enhancing the stability of the entire fixed device and ensuring the processing accuracy.

Detailed Implementation

[0028] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0029] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0030] like Figure 1 As shown, a fixing device for workpiece processing in this solution is mainly used to fix the workpiece during processing.

[0031] like Figures 1 to 4 As shown, this solution provides a fixing device for workpiece processing, comprising a fixing frame 1; a longitudinal fixing unit 2, which is disposed on the fixing frame 1 and has a fixing block 3 and a clamping block 4, the clamping block 4 being movably disposed above the fixing block 3, the fixing block 3 providing support for the workpiece, and the clamping block 4 movably abutting against one side of the workpiece in the vertical direction for fixing the workpiece in the vertical direction; a transverse fixing unit 5, which is disposed on the fixing frame 1 and has a first clamping block 6 and a second clamping block 7, the first clamping block 6 and the second clamping block 7 respectively movably abutting against both sides of the workpiece in the horizontal direction for fixing the workpiece in the horizontal direction; a fixing space 8 is formed between the longitudinal fixing unit 2 and the transverse fixing unit 5, the fixing space 8 being adapted to the outer contour of the workpiece, and the fixing space 8 being able to fit against the outer surface of the workpiece because the workpiece is fixed on the fixing frame 1, thereby increasing the contact area between the fixing device and the workpiece.

[0032] During operation, the workpiece is first placed on the fixing block 3. Then, the clamping block 4 moves vertically towards the workpiece until it makes tight contact with one side of the workpiece, providing vertical fixing force. Simultaneously, the first clamping block 6 and the second clamping block 7 approach the workpiece from both sides horizontally. When the first clamping block 6 and the second clamping block 7 are in tight contact with both sides of the workpiece, they provide stable horizontal fixation. This step further enhances the stability of the workpiece, preventing it from moving left or right during processing. After completing the above steps, the clamping block 4 and the fixing block 3... A fixed space 8 that fits the outer contour of the workpiece is formed between the first clamping block 6 and the second clamping block 7. This fixed space 8 not only increases the contact area between the fixing device and the workpiece, but also significantly improves the overall fixing effect. The fixing device in this embodiment, through the design of the longitudinal fixing unit 2 and the transverse fixing unit 5, can firmly fix the workpiece in the vertical and horizontal directions and form a fixed space 8 that fits the outer contour of the workpiece. This ensures that the workpiece remains highly stable throughout the entire processing process, avoids displacement problems caused by improper fixing, and thus guarantees the high quality and consistency of the final product.

[0033] In order to move the clamping block 4 in the vertical direction, the longitudinal fixing unit 2 also includes a first driving member 9. The output end of the first driving member 9 is connected to a movable seat 10, and the clamping block 4 is connected to the movable seat 10. The first driving member 9 drives the clamping block 4 to move in the vertical direction through the movable seat 10. When the workpiece is placed on the fixing block 3, the first driving member 9 moves immediately, driving the movable seat 10 to move in the vertical direction, thereby driving the clamping block 4 to approach the workpiece in the vertical direction until the clamping block 4 is in close contact with the workpiece. The first driving member 9 stops driving, and the vertical fixing of the workpiece is completed. The first driving member 9 can be a motor, a hydraulic cylinder or a pneumatic cylinder.

[0034] In order to move the first clamping block 6 in the horizontal direction, the transverse fixing unit 5 also includes a second driving member 11, and the first clamping block 6 is connected to the output end of the second driving member 11.

[0035] In order to move the second clamping block 7 in the water direction, the transverse fixing unit 5 also includes a third driving member 12, and the second clamping block 7 is connected to the output end of the third driving member 12.

[0036] When the clamping block 4 makes close contact with one side of the workpiece, the second driving component 11 and the third driving component 12 start synchronously, driving the first clamping block 6 and the second clamping block 7 to move towards both sides of the workpiece in the horizontal direction until the first clamping block 6 and the second clamping block 7 make close contact with the workpiece, providing horizontal fixation for the workpiece. At this time, a fixed space 8 that fits the outer contour of the workpiece is formed between the fixing block 3, the clamping block 4, the first clamping block 6 and the second clamping block 7. By increasing the contact area, the stability of the fixing device in this solution for fixing the workpiece is enhanced. The first driving component 9 and the second driving component 11 can be a motor, a hydraulic cylinder or a pneumatic cylinder.

[0037] To increase the friction between the fixing block 3 and the workpiece, a first tooth structure 13 is provided on one side surface of the fixing block 3. When the workpiece is placed on the fixing block 3, the first tooth structure 13 will form multiple contact points with the workpiece surface due to the weight of the workpiece itself. These contact points significantly increase the friction between the fixing block 3 and the workpiece surface, thereby enhancing the fixing effect of the workpiece and reducing the risk of displacement of the workpiece due to vibration or external force during processing.

[0038] To increase the friction between the clamping block 4 and the workpiece, a second tooth structure 14 is provided on one side surface of the clamping block 4. The second tooth structure 14 is provided on one side surface of the clamping block 4, that is, the side that contacts the workpiece. When the clamping block 4 moves closer to the workpiece in the vertical direction and abuts against it, the second tooth structure 14 will make close contact with the surface of the workpiece and abut against it, thereby increasing the friction between the two and enhancing the overall fixing effect.

[0039] To provide positioning for the workpiece, the fixing block 3 is also provided with a positioning groove 15. When the workpiece is placed on the fixing block 3, its edge or a specific part is embedded in the positioning groove 15 to ensure that the correct position is fixed. By setting the positioning groove 15, the position of the workpiece on the fixing block 3 can be ensured to be accurate, which helps to improve the machining accuracy.

[0040] Furthermore, the movable seat 10 is provided with an outwardly extending protrusion 16, and the fixed frame 1 is provided with a guide groove 17, in which the protrusion 16 is movably inserted.

[0041] Furthermore, the fixed frame 1 is detachably connected to a support block 18 disposed opposite to it, and a guide groove 17 is formed between the two support blocks 18. The support block 18 and the fixed frame 1 can be connected by a thread.

[0042] When the first driving member 9 drives the movable seat 10 to move in the vertical direction, the protrusion 16 slides along the guide groove 17, thereby providing guidance for the movement of the movable seat 10 and the clamping block 4. In addition, when the workpiece is being processed, the workpiece will exert a force on the clamping block 4. Since the clamping block 4 is connected to the movable seat 10, the force exerted by the workpiece also acts on the movable seat 10. In this case, the movable seat 10 is in close contact with the support block 18 through the protrusion 16 under the force of the workpiece. The support block 18 provides support for the movable seat 10 through its cooperation with the protrusion 16, effectively preventing the movable seat 10 and the clamping block 4 from displacing due to force, ensuring the stability of the structure. This design also enhances the stability of the entire fixing device, thereby ensuring the processing accuracy.

[0043] Furthermore, a rotating component 19 is provided on one side of the clamping block 4. When the workpiece contacts the clamping block 4, the rotating component 19 will be driven to rotate by the workpiece. When the workpiece is processed, the workpiece will contact the outer wall of the clamping block 4 and move along the outer wall of the clamping block 4. The design of the rotating component 19 changes the contact between the workpiece and the clamping block 4 from sliding contact to rolling contact, reducing the stress on the workpiece surface and thus preventing the workpiece surface from being damaged or deformed due to contact. This design effectively reduces the risk of workpiece surface damage or deformation, and is particularly suitable for high-precision processing scenarios to ensure the surface quality of the workpiece during the processing.
