Description

Technical Field

[0001] The present invention relates to the technical field of clamping tooling, and particularly relates to a positioning fixture and a positioning tooling for angle steel. Background Art

[0002] Angle steel members are commonly used members in the manufacturing of engineering machinery and equipment, such as the standard sections of tower crane fish plates. During the mass production process of angle steel members, it is necessary to use fixtures to fix the angle steel, and then weld different functional structures such as connecting plates, grooves, and holes on it. Existing positioning fixtures for angle steel all use positioning parts and pressing mechanisms to cooperate to position and fix the angle steel. When in use, it is necessary for workers to first place the angle steel and move the angle steel to abut against the positioning parts to form a position, and then use the pressing mechanism to press and fix the angle steel. There are problems such as high manual labor intensity, inconvenient movement, and low efficiency. Especially when the size and weight of a single angle steel increase, this problem becomes more prominent. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a positioning fixture and a positioning tooling for angle steel that can reduce the manual labor intensity and improve the operation simplicity and efficiency.

[0004] The present invention adopts the following technical solutions:

[0005] A positioning fixture for angle steel, comprising:

[0006] A base having a plurality of support seats for placing angle steel;

[0007] An end positioning part provided on the base and having a baffle for the end of the angle steel to abut against for positioning;

[0008] A plurality of side positioning parts provided on the base and having abutting parts for the side of the angle steel to abut against for positioning;

[0009] A pressing assembly including a plurality of pressing modules arranged at intervals in sequence along the length direction of the angle steel;

[0010] A side positioning drive assembly oppositely arranged with the side positioning part, including a side positioning drive module for pushing the angle steel to move and abut against the side positioning part;

[0011] An end positioning drive assembly provided on the base and oppositely arranged with the end positioning part, including an end positioning drive module for pushing the angle steel to abut against the end positioning part for positioning;

[0012] The side positioning drive assembly can push the angle steel to move from the opposite side of the side positioning piece to abut against the side positioning piece, and the end positioning drive assembly can push the angle steel from the other end of the angle steel to abut and position against the end positioning piece, without manually moving and adjusting the position of the angle steel for positioning, which can reduce the labor intensity, improve the operation simplicity and efficiency;

[0013] Through the coordinated action of multiple components, three-dimensional positioning control of the angle steel is achieved. Among them, the support seat provides basic support, the end positioning piece and the end positioning drive assembly achieve lengthwise positioning, the side positioning piece and the side positioning drive assembly achieve widthwise positioning system, and the pressing assembly achieves vertical fixing; this structure realizes efficient and precise positioning of the angle steel through modular design, and solves the technical problems of incomplete positioning dimensions and cumbersome adjustment procedures of traditional jigs.

[0014] Preferably, the angle steel includes a first steel surface and a second steel surface arranged vertically. The first steel surface is located on the support seat, the second steel surface abuts against the abutting piece, the pressing module presses on the upper end surface of the second steel surface, and the side positioning drive module abuts against the side end surface of the first steel surface when pushing the angle steel to move. By defining the positioning methods of the two vertical surfaces of the angle steel, a three-dimensional positioning reference system is constructed. Taking the upper end surface of the second steel surface as the pressing contact surface can ensure the stability of the applied force and avoid damaging the working surface; selecting the side end surface of the first steel surface as the driving contact surface forms a clear positioning reference surface. This positioning strategy effectively solves the clamping deviation problem caused by the unclear positioning reference of the L-shaped workpiece.

[0015] Preferably, the support seat is provided with a semi-cylindrical or triangular prism-shaped support portion. The support portion is in linear contact with the angle steel, and the contact line between the support portion and the angle steel extends along the direction in which the side positioning drive assembly pushes the angle steel to move, reducing the contact friction and facilitating the movement of the angle steel during position adjustment. A definite support track is formed through linear contact, improving the support stability.

[0016] Preferably, the upper end of the baffle is provided with an anti-disengagement protrusion, forming a mechanical limit structure, which not only ensures that the angle steel will not disengage from the positioning reference when the drive assembly applies a thrust, but also retains enough operating space for workpiece picking and placing, effectively solving the safety hazard of workpiece jumping off during high-speed positioning.

[0017] Preferably, the abutting piece includes a connecting seat and a roller rotatably fitted on the connecting seat. The roller-type abutting piece converts sliding friction into rolling friction, enabling the angle steel to be slightly adjusted axially during positioning, ensuring both lateral positioning accuracy and avoiding scratching the workpiece surface, and is particularly suitable for precision machining scenarios that require repeated fine-tuning positioning.

[0018] Preferably, the pressing module includes a pressing member and a pressing driving mechanism. The pressing member is detachably connected to the driving end of the pressing driving mechanism and can be driven by the pressing driving mechanism to move up and down to loosen and press the angle steel. Since the pressing member is prone to wear during long-term use, it may not be able to stably and reliably press the angle steel. The pressing member is installed at the driving end of the pressing driving mechanism in a detachable manner, which is convenient for replacing the worn pressing member and ensuring stable and reliable pressing.

[0019] Preferably, the side positioning driving module includes a pushing roller and a first telescopic driving member. The pushing roller is rotatably installed at the driving end of the first telescopic driving member and can be driven by the first telescopic driving member to reciprocate to push the angle steel to move and abut against the side positioning member and move away from the angle steel abutting against the side positioning member. The combination of the pushing roller and the telescopic driving forms a flexible force application system, which can avoid scratching the workpiece through rolling contact while ensuring sufficient thrust.

[0020] Preferably, after the pushing roller pushes the angle steel to move and abut against the side positioning member for positioning, the pushing roller and the side positioning member form a limiting component for limiting the angle steel. After the pushing roller pushes the angle steel to move and abut against the side positioning member for positioning, the pushing roller and the side positioning member can limit the angle steel. With the cooperation of the pressing module, the angle steel can only move along its length direction, which is convenient for the end positioning driving component to push the angle steel from the other end of the angle steel to abut against the end positioning member for positioning, avoiding the situation of being unable to push and reducing the performance requirements for the end positioning driving component.

[0021] Preferably, the end positioning driving module includes a pushing block and a second telescopic driving member. The pushing block is connected to the driving end of the second telescopic driving member and can be driven by the second telescopic driving member to reciprocate to push the angle steel from one end of the angle steel to abut against the end positioning member and move away from the end of the angle steel abutting against the end positioning member.

[0022] A positioning tool for angle steel includes a base and a plurality of positioning jigs installed on the base. Through modular layout design, a plurality of positioning units are integrated on the base to achieve batch production.

[0023] Compared with the prior art, the present invention has the following advantages: Through the side positioning drive assembly, the angle steel can be pushed from the opposite side of the side positioning member to abut against the side positioning member, and through the end positioning drive assembly, the angle steel can be pushed from the other end of the angle steel to abut and be positioned against the end positioning member, without the need for manual movement and adjustment of the position of the angle steel for positioning, which can reduce the labor intensity of workers, improve the simplicity and efficiency of operation; Through the coordinated action of multiple components, three-dimensional positioning control of the angle steel is achieved. Among them, the support seat provides basic support, the end positioning member and the end positioning drive assembly achieve length-direction positioning, the side positioning member and the side positioning drive assembly achieve width-direction positioning, and the pressing assembly achieves vertical-direction fixation; This structure realizes efficient and accurate positioning of the angle steel through modular design, and solves the technical problems of incomplete positioning dimensions and cumbersome adjustment processes of traditional jigs.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] In order to facilitate understanding of the technical solution of the present invention, the following is a detailed description in combination with the accompanying drawings and specific embodiments.

[0029] Embodiment 1

[0030] As Figures 1-3 shown, a positioning jig for angle steel includes:

[0031] Base 1, having a plurality of support seats 1-1 for placing angle steel;

[0032] End positioning member 2, arranged on the base 1, having a baffle 2-1 for the end of the angle steel to abut and be positioned;

[0033] A plurality of side positioning members 3 are arranged on the base 1 and have abutting members for the side of the angle steel to abut and be positioned;

[0034] The pressing assembly 4 includes a plurality of pressing modules arranged at intervals in sequence along the length direction of the angle steel;

[0035] The side positioning drive assembly 5 is arranged opposite to the side positioning member 3 and includes a side positioning drive module for pushing the angle steel to move and abut against the side positioning member 3;

[0036] The end positioning drive assembly 6 is arranged on the base 1 and is arranged opposite to the end positioning member 2 and includes an end positioning drive module for pushing the angle steel to abut and be positioned against the end positioning member 2;

[0037] Through the side positioning drive assembly, the angle steel can be pushed to move from the opposite side of the side positioning member to abut against the side positioning member. Through the end positioning drive assembly, the angle steel can be pushed from the other end of the angle steel to abut and be positioned against the end positioning member, without the need for manual movement and adjustment of the position of the angle steel for positioning, which can reduce the labor intensity of workers, improve the operation simplicity and efficiency;

[0038] Through the coordinated action of multiple components, three-dimensional positioning control of the angle steel is achieved. Among them, the support seat provides basic support, the end positioning member and the end positioning drive assembly achieve length direction positioning, the side positioning member and the side positioning drive assembly achieve width direction positioning system, and the pressing assembly achieves vertical direction fixation; This structure realizes the efficient and accurate positioning of the angle steel through modular design, and solves the technical problems of incomplete positioning dimensions and cumbersome adjustment procedures of traditional jigs.

[0039] The angle steel includes a first steel surface 7 and a second steel surface 8 arranged vertically. The first steel surface 7 is located on the support seat 1-1, the second steel surface 8 abuts against the abutting member, the pressing module presses on the upper end surface 8-1 of the second steel surface 8, and when the side positioning drive module pushes the angle steel to move, it abuts against the side end surface 7-1 of the first steel surface 7. By defining the positioning methods of the two vertical surfaces of the angle steel, a three-dimensional positioning reference system is constructed. Taking the upper end surface of the second steel surface as the pressing contact surface not only ensures the stability of the applied force but also avoids damaging the working surface; Selecting the side end surface of the first steel surface as the driving contact surface forms a clear positioning reference surface, and this positioning strategy effectively solves the clamping deviation problem caused by the unclear positioning reference of the L-shaped workpiece.

[0040] The support seat 1-1 is provided with a semi-cylindrical or triangular prism-shaped support portion 1-2. The support portion 1-2 is in linear contact with the angle steel, and the contact line between the support portion 1-2 and the angle steel extends along the direction in which the side positioning drive assembly 5 pushes the angle steel to move, reducing the contact friction and facilitating the movement of the angle steel during position adjustment. A deterministic support trajectory is formed through line contact, improving the support stability.

[0041] The upper end of the baffle 2-1 is provided with an anti-disengagement protrusion 2-2, forming a mechanical limit structure, which not only ensures that the angle steel will not disengage from the positioning reference when the driving component applies thrust, but also retains enough operating space for easy workpiece picking and placing, effectively solving the safety hazard of workpiece disengagement during high-speed positioning.

[0042] The abutting member includes a connecting seat 3-1 and a roller 3-2 rotatably fitted on the connecting seat 3-1. The roller-type abutting member converts sliding friction into rolling friction, enabling the angle steel to be slightly adjusted axially during positioning, which not only ensures the lateral positioning accuracy but also avoids scratching the surface of the workpiece, and is particularly suitable for precision machining scenarios that require repeated fine-tuning positioning.

[0043] The pressing module includes a pressing member 4-1 and a pressing driving mechanism 4-2. The pressing member 4-1 is detachably connected to the driving end of the pressing driving mechanism 4-2 and can be driven by the pressing driving mechanism 4-2 to move up and down to loosen and press the angle steel. Since the pressing member 4-1 is prone to wear during long-term use, which may lead to the inability to stably and reliably press the angle steel, the pressing member 4-1 is installed at the driving end of the pressing driving mechanism 4-2 in a detachable manner, facilitating the replacement of the worn pressing member 4-1 to ensure stable and reliable pressing.

[0044] The side positioning driving module includes a pushing roller 5-1 and a first telescopic driving member 5-2. The pushing roller 5-1 is rotatably installed at the driving end of the first telescopic driving member 5-2 and can be driven by the first telescopic driving member 5-2 to reciprocate to push the angle steel to move and abut against the side positioning member 3 and move away from the angle steel abutting against the side positioning member 3. The combination of the pushing roller and the telescopic drive forms a flexible force application system, which while ensuring sufficient thrust, avoids scratching the workpiece through rolling contact.

[0045] After the pushing roller 5-1 pushes the angle steel to move and abut against the side positioning member 3 for positioning, the pushing roller 5-1 and the side positioning member 3 form a limiting component for the angle steel. After the pushing roller 5-1 pushes the angle steel to move and abut against the side positioning member for positioning, the pushing roller and the side positioning member even play a limiting role on the angle steel. With the cooperation of the pressing module, the angle steel can only move along its length direction, facilitating the end positioning driving component to push the angle steel from the other end of the angle steel to abut against the end positioning member for positioning, avoiding the situation of being unable to push, and also reducing the performance requirements for the end positioning driving component.

[0046] The end positioning driving module includes a pushing block 6-1 and a second telescopic driving member 6-2. The pushing block 6-1 is connected to the driving end of the second telescopic driving member 6-2 and can be driven by the second telescopic driving member 6-2 to reciprocate to push the angle steel from one end of the angle steel to abut against the end positioning member 2 and move away from one end of the angle steel abutting against the end positioning member 2.

[0047] The above-mentioned first telescopic driving member 5-2, second telescopic driving member 6-2 and pressing driving mechanism 4-2 can all adopt reciprocating driving members or driving mechanisms such as cylinders, oil cylinders or electric push rods. The pressing driving mechanism 4-2 can also adopt other existing mechanisms that can drive the pressing member 4-1 to move up and down.

[0048] A positioning tooling for angle steel includes a base 1 and a plurality of positioning jigs installed on the base 1. Through modular layout design, a plurality of positioning units are integrated on the base to achieve batch production.

[0049] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is subject to the scope defined by the claims. Several improvements and refinements made by those skilled in the art without departing from the spirit and scope of the present invention should also be regarded as the protection scope of the present invention.
