Description

Technical Field

[0001] This utility model relates to the field of tooling fixtures, and in particular to an inclined positioning tooling fixture. Background Technology

[0002] In modern manufacturing, drilling and grooving are common machining operations on workpieces. However, when these operations are performed on specific sides or bevels of a workpiece, numerous challenges arise. Traditional fixtures are typically designed based on the workpiece's conventional plane or standard angles, making it difficult to accurately and securely hold workpieces with bevels or irregular shapes. This leads to frequent workpiece displacement and wobbling during machining, resulting in quality problems such as drilling position deviations and uneven grooving depths.

[0003] In order to ensure machining accuracy, operators have to spend a lot of time repeatedly adjusting the position of the workpiece, which is cumbersome and inefficient. In addition, the operator's adjustment of the workpiece or the adjustment and clamping of the tool can easily cause angular deviations, affecting the consistency of the workpiece machining. Utility Model Content

[0004] In order to standardize the machining operations such as bevel drilling and grooving of workpieces and achieve a more consistent machining process, this utility model provides a bevel positioning fixture.

[0005] This utility model provides a technical solution that adopts the following approach:

[0006] An inclined positioning fixture includes a fixture body with a recessed support groove for inserting a workpiece. The shape of the support groove is adapted to the shape of the workpiece insertion end. The inner wall of the support groove fits against the outer wall of the workpiece insertion part. The support groove includes at least three inner walls with different length directions. A vacuum section is also provided in the support groove. The vacuum section is connected to a negative pressure device and communicates with the internal space of the support groove.

[0007] The workpiece is placed in the support groove, and then the negative pressure device is turned on, causing the vacuum section to draw air inward, thus adhering the workpiece to the support groove and preventing it from easily separating from the groove. At this point, the side of the workpiece that needs to be drilled or slotted faces the machining tool. The support groove restricts the movement of the workpiece, making the machining more standardized and reducing deviations in machining results caused by workpiece offset. Simultaneously, the constraint of the inner wall of the support groove means that the angle setting of the workpiece does not require excessive adjustment, making the machining process more convenient.

[0008] Preferably, the vacuum section includes a ventilation groove, and at least one ventilation groove is provided on the inner wall of each side of the support groove. The ventilation groove extends along the inclined surface and penetrates the side wall in its extension direction.

[0009] Each inner wall of the support groove is equipped with a ventilation groove. When the negative pressure device vents air towards the ventilation groove, each inner wall of the support groove can provide adsorption force for the workpiece, which helps to improve the stability of workpiece processing and makes the processed holes or grooves more standard.

[0010] Preferably, all of the ventilation slots are connected, and one of the ventilation slots is directly connected to the negative pressure device.

[0011] The negative pressure device only needs to connect to one vent slot to supply air to multiple vent slots at the same time, which helps to simplify the overall structure and wiring, while also saving power and thus saving costs.

[0012] Preferably, the ventilation groove is located at the junction of two adjacent inner sidewalls of the support groove, and the ventilation groove extends along the junction edge between the two inner sidewalls.

[0013] Ventilation channels are placed at the corners to avoid the edges and corners of the workpiece, preventing impact damage.

[0014] Preferably, the inner wall of the support groove has a plurality of suction grooves, which are connected to a negative pressure device.

[0015] The suction grooves can increase the adsorption effect of each side wall on the workpiece, making the workpiece more stable.

[0016] Preferably, the multiple air intake slots located on the same side wall of the support slot are interconnected.

[0017] Since multiple suction slots are connected, negative pressure only needs to be introduced into one of the suction slots, which helps to simplify the device.

[0018] Preferably, the air intake groove is connected to the air vent groove.

[0019] Connecting the air intake and negative pressure devices via the ventilation channel simplifies the device, improves the overall consistency of the device's operating frequency, and makes the adsorption of the workpiece more stable.

[0020] In summary, this utility model has the following beneficial technical effects:

[0021] The workpiece is placed in the support groove, and then the negative pressure device is turned on, causing the vacuum section to draw air inward, thus adhering the workpiece to the support groove and preventing it from easily separating from the groove. At this point, the side of the workpiece that needs to be drilled or slotted faces the machining tool. The support groove restricts the movement of the workpiece, making the machining more standardized and reducing deviations in machining results caused by workpiece offset. Simultaneously, the constraint of the inner wall of the support groove means that the angle setting of the workpiece does not require excessive adjustment, making the machining process more convenient.

[0023] Explanation of reference numerals in the attached drawings: 1. Fixture body; 2. Support groove; 3. Ventilation groove. Detailed Implementation

[0024] The following is in conjunction with the appendix Figure 1 The present invention will be described in further detail below.

[0025] This utility model discloses an inclined positioning tooling fixture.

[0026] Reference Figure 1 A slant positioning fixture includes a fixture body 1, a support groove 2 recessed on the fixture body 1 for inserting a workpiece, the shape of the support groove 2 being adapted to the shape of the workpiece insertion end, the inner wall of the support groove 2 being fitted to the outer wall of the workpiece insertion part, the support groove 2 including at least three inner walls with different length directions; the support groove 2 is also provided with a vacuum section, the vacuum section being connected to a negative pressure device, and the vacuum section being in communication with the internal space of the support groove 2.

[0027] The workpiece is placed in the support groove 2, and then the negative pressure device is turned on, causing the vacuum section to draw air inward, thus adhering the workpiece to the support groove 2 and preventing it from easily separating from it. At this time, the side of the workpiece that needs to be drilled or slotted faces the machining tool. The support groove 2 restricts the movement of the workpiece, making the machining of the workpiece more standardized and reducing the possibility of deviations in machining results due to workpiece offset. At the same time, the restriction of the inner wall of the support groove 2 means that the angle setting of the workpiece does not require much adjustment, making the machining of the workpiece more convenient.

[0028] Reference Figure 1 In this embodiment, the vacuum section includes a ventilation groove 3. Each inner wall of the support groove 2 is provided with at least one ventilation groove 3. The ventilation groove 3 extends along the inclined surface and penetrates the side wall in its extension direction.

[0029] Each inner wall of the support groove 2 is provided with a ventilation groove 3. When the negative pressure device vents air towards the ventilation groove 3, each inner wall of the support groove 2 can provide adsorption force for the workpiece, which is beneficial to improving the stability of workpiece processing and making the processed holes or grooves more standard.

[0030] Reference Figure 1 In this embodiment, multiple ventilation slots 3 are connected, and one of the ventilation slots 3 is directly connected to the negative pressure device.

[0031] The negative pressure device only needs to connect to one ventilation slot 3 to supply air to multiple ventilation slots 3 at the same time, which helps to simplify the overall structure and wiring, while saving power and thus saving costs.

[0032] Reference Figure 1In this embodiment, the ventilation groove 3 is located at the junction of two adjacent inner sidewalls of the support groove 2, and the ventilation groove 3 extends along the junction edge between the two inner sidewalls.

[0033] Ventilation groove 3 is located at the corner to avoid the corners of the workpiece and prevent impact damage.

[0034] Reference Figure 1 In this embodiment, the inner wall of the support groove 2 is recessed with multiple air suction grooves, which are connected to the negative pressure device.

[0035] The suction grooves can increase the adsorption effect of each side wall on the workpiece, making the workpiece more stable.

[0036] Reference Figure 1 In this embodiment, multiple air intake slots located on the same side wall of the support slot 2 are interconnected.

[0037] Since multiple suction slots are connected, negative pressure only needs to be introduced into one of the suction slots, which helps to simplify the device.

[0038] Reference Figure 1 In this embodiment, the air intake groove is connected to the air vent 3.

[0039] By connecting the air intake and the negative pressure device through the ventilation slot 3, the device can be further simplified and the overall operating frequency of the device can be improved, thereby making the adsorption of the workpiece more stable.

[0040] Reference Figure 1 The depth of the ventilation groove 3 is greater than the depth of the suction groove. Since the ventilation groove 3 needs to supply air to the suction groove, the ventilation volume in the ventilation groove 3 is large, and a larger depth needs to be set to meet the needs of the suction groove.

[0041] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
