Description

Technical Field

[0001] The present application relates to the technical field of mechanical processing fixtures, and in particular to a door component positioning tool. Background Art

[0002] Door parts are parts used to connect the car body and car doors, such as Figure 1 and Figure 2 shown. Figure 1 The right door component 1 is a finished product. The right door component 1 includes an integrally formed mounting block 101 and a corner block 102. The side wall of the mounting block 101 facing away from the corner block 102 is marked as a mounting surface 103, and the mounting surface 103 is fixed to the vehicle body. When processing the right door component 1, the two shoulders of the corner blank need to be milled off to form the corner block 102, and the two shoulders of the corner block 102 are asymmetrical, the side with a larger milling area is the upper side, and the side with a smaller milling area is the lower side. The corner block 102 is also provided with an axle pin hole 104 in the vertical direction for inserting an axle pin to hinge the vehicle door. Figure 2 The left door component 2 is a processed left door component 2 , the shape of which is similar to that of the right door component 1 , and the left door component 2 and the right door component 1 are mirror-imaged along the plane where the mounting surface 103 is located.

[0003] When processing the two shoulders of the door parts, they need to be positioned before processing. The Chinese patent announcement number is CN209614927U, and the announcement date is November 12, 2019. The name of the invention is a fixture for auxiliary tooling for door parts processing. The application discloses a fixture that can position the door blank. The corner block of the door part is placed upward in the fixture. The door part is positioned and tightened by the fixture bottom plate, fixed side positioning clamping block, movable side positioning clamping block, upper surface positioning support block and lower surface positioning support block.

[0004] However, in the above-mentioned related technologies, the fixed side positioning clamping block, the movable side positioning clamping block, the upper surface positioning support block and the lower surface positioning support block can clamp the vehicle door component from four horizontal directions, while in the vertical direction, only the clamp bottom plate is used to support the bottom of the vehicle door component, and there is no positioning measure on the top, which may cause inaccurate positioning in the vertical direction, thereby affecting the processing accuracy of the two shoulders of the vehicle door component. Utility Model Content

[0005] In order to improve the problem of inaccurate processing caused by inaccurate positioning of the door component by the clamp, the present application provides a door component positioning tool, which is used to clamp and position the door component in three dimensions and six directions when processing the two shoulders of the door component, which is beneficial to improve the clamping stability of the door component.

[0006] The present application provides a door positioning tool, which adopts the following technical solution:

[0007] A door component positioning tool comprises a base plate, on which a clamp seat for facilitating the placement of the door component and a positioning assembly for positioning the door component on the clamp seat are fixedly arranged, the positioning assembly comprising a first positioning portion, a second positioning portion and a third positioning portion that can simultaneously abut against the door component, the force direction of the first positioning portion is recorded as a first direction, the force direction of the second positioning portion is recorded as a second direction, and the force direction of the third positioning portion is recorded as a third direction, and the first direction, the second direction and the third direction are perpendicular to each other.

[0008] By adopting the above technical scheme, the first positioning part, the second positioning part and the third positioning part can perform three-dimensional six-directional positioning of the door component, that is, the up and down, left and right, front and back of the door component are all positioned, thereby reducing the probability of the door component falling off or sliding out in a certain direction after positioning, improving the positioning effect of the door component, and facilitating more precise processing of the shoulders of the door component.

[0009] Optionally, the clamp seat is provided with a placement groove for inserting the door component mounting block, and the first positioning portion, the second positioning portion and the third positioning portion are all abutted against the door component mounting block; the clamp seat is also provided with a processing groove for facilitating tool feeding, the processing groove is connected to the placement groove, and the door component corner block is located in the processing groove.

[0010] By adopting the above technical solution, when the mounting block of the door component is located in the placement groove, the corner block of the door component can be exposed in the processing groove, so that it is convenient for the processing tool to enter the processing groove to process the two shoulders of the corner block.

[0011] Optionally, the upper side of the door member corner block is placed downward, and the processing groove extends in the vertical direction.

[0012] By adopting the above technical solution, since more material needs to be milled off on the upper side of the corner block, the side that produces more waste is set downward, which makes it easier for the waste to automatically fall due to gravity during processing, thereby reducing the impact of the waste on the processing quality during processing.

[0013] Optionally, the first positioning portion includes a ball screw threadedly connected to the clamp seat, the axial direction of the ball screw is horizontally arranged and parallel to the first direction, the ball screw passes through the placement groove and abuts against the vehicle door component, and the side wall of the vehicle door component away from the ball screw can abut against the inner wall of the placement groove.

[0014] By adopting the above technical solution, the door member is positioned by using the ball screw in the prior art, and the ball of the ball screw is supported by the spring inside the ball screw, so that the ball can roll and be retracted or ejected. When the door member is inserted into the placement groove, the rolling of the ball can be used to reduce the friction between the ball and the door member, and the support force of the spring on the ball can also be used to make the ball press the door member against the inner wall of the placement groove, thereby realizing the position locking of the door member in the first direction.

[0015] Optionally, an extended stop block is fixedly provided on the inner wall of the processing groove, and the extended stop block can abut against the outer wall of the door component corner block, and the ball screw abuts against the end of the door component mounting block; and the thickness of the extended stop block is smaller than the thickness of the processed door component corner block.

[0016] By adopting the above technical solution, the extended block can increase the support area of ​​the door component away from the ball screw side, which is beneficial to enhance the positioning effect; at the same time, the thickness of the extended block is limited so that the upper and lower surfaces of the extended block are located within the upper and lower surfaces of the corner block of the door component, thereby avoiding the processing tool at the shoulders of the door component.

[0017] Optionally, the second positioning portion includes a vertical driving seat fixed to the base plate, and a vertical driving source moving along the second direction is provided on the vertical driving seat; a vertical connecting rod is also hinged on the vertical driving seat, and a vertical pressure block is hinged at one end of the vertical connecting rod away from the vertical driving seat, the vertical driving source is hinged to the end of the vertical pressure block, and the end of the vertical pressure block away from the vertical driving source abuts against the vehicle door component.

[0018] By adopting the above technical solution, when the vertical driving source drives one end of the vertical pressing block to lift, the end of the vertical pressing block away from the vertical driving source abuts against the door member by utilizing the lever principle, thereby realizing the positioning of the door member in the second direction.

[0019] Optionally, the third positioning portion includes a transverse driving seat fixed to the base plate, and a transverse driving source moving along a third direction is provided on the transverse driving seat; a transverse connecting rod is also hinged on the transverse driving seat, and a transverse pressure block is hinged on the end of the transverse connecting rod away from the transverse driving seat, the transverse driving source is hinged to the end of the transverse pressure block, and the end of the transverse pressure block away from the transverse driving source abuts against the vehicle door component.

[0020] By adopting the above technical solution, when the lateral driving source drives one end of the lateral pressing block to lift, the end of the lateral pressing block away from the lateral driving source abuts against the door component by utilizing the lever principle, thereby realizing the positioning of the door component in the third direction.

[0021] Optionally, the lateral pressing block is provided with an avoidance surface on the edge facing the processing groove.

[0022] By adopting the above technical solution, on the one hand, the probability of collision between the tool and the fixture during processing can be reduced. On the other hand, the opening of the avoidance surface allows the abutment position of the lateral pressure block and the door component mounting block to be as close to the door component corner block as possible, thereby increasing the contact area between the lateral pressure block and the door component mounting block, thereby enhancing the positioning effect.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The door parts are positioned in three dimensions and six directions, which improves the positioning effect of the door parts and facilitates more accurate processing of the shoulders of the door parts;

[0025] 2. When processing door parts, place the upper side of the corner block downward, that is, the side that produces more waste is placed downward, so that the waste can fall automatically due to gravity during processing, reducing the impact of waste on processing quality.
