Description

Technical Field

[0001] This utility model relates to the field of clamping fixtures, specifically to a bidirectional clamping fixture for the inner and outer walls of a plastic structural component. Background Technology

[0002] In the processing of plastic structural parts, clamping fixtures are key equipment to ensure processing accuracy. They need to stably fix the structural parts to avoid displacement or damage during processing.

[0003] Currently, most clamping fixtures fix plastic structural parts by clamping them around the outer wall. This structure only acts on the outer wall and cannot effectively clamp the inner wall. Because plastic materials have inherent toughness and are easily deformed, clamping only around the outer wall is insufficient to create comprehensive and stable constraints. In practical use, problems such as loosening of the structural parts and positioning deviations often occur. Furthermore, over-clamping can easily cause irreversible deformation of the outer wall of the structural part, seriously affecting processing accuracy and product yield, and failing to meet the processing requirements of high-precision plastic structural parts.

[0006] As a further improvement of this utility model, the main body segment is integrally connected to a transverse segment at one end away from the hook-shaped segment.

[0007] As a further improvement of this utility model, the hook-shaped segment extends vertically downward, and the width of the inner wall clamping member in the hook-shaped segment is smaller than the width of the inner wall clamping member in the main body segment.

[0008] As a further improvement of this utility model, there are two inner wall clamping members, and the arrangement direction of the two outer wall clamping members is perpendicular to the arrangement direction of the two inner wall clamping members.

[0009] As a further improvement of this utility model, the inner wall stabilizer includes a T-shaped block located inside the cavity of the plastic structural component, the hook-shaped segment is located between the T-shaped block and the inner wall of the plastic structural component, and outer wall clamping components are arranged in the left and right directions of the T-shaped block, and inner wall clamping components are arranged in the front and back directions of the T-shaped block.

[0010] As a further improvement of this utility model, each outer wall clamping member includes two positioning protrusions that can contact the outer wall of the plastic structural member, and an inner recess is formed between the two positioning protrusions.

[0014] As a further improvement of this utility model, the upper surface of the fixture plate is provided with a linear guide groove, and the outer wall clamping member is movably assembled with the linear guide groove.

Detailed Implementation

[0021] The present invention will be further described in detail below with reference to specific embodiments: To achieve the purpose of this utility model, please refer to Figures 1 to 5A bidirectional clamping fixture for the inner and outer walls of a plastic structural component includes: two outer wall clamping members 3 capable of linear motion toward or away from each other, clamping the outer wall of the plastic structural component 6 when they approach each other; an inner wall stabilizing member 5 passing through and located within the cavity of the plastic structural component 6, positioned along the axis of the plastic structural component 6; and an inner wall clamping member 1 including a main body section 101 and a hook-shaped section 103 at an angle to each other, the hook-shaped section 103 extending into the space of the plastic structural component 6 and contacting the inner wall of the plastic structural component 6, while the main body section 101 is located outside the plastic structural component 6. A spring 2 is fitted to the end of the main body section 101 facing away from the hook-shaped section 103, the spring 2 providing an outward elastic force along the radial direction of the plastic structural component 6 to the inner wall clamping member 1, thus exerting an outward hooking force on the plastic structural component 6.

[0022] In order to clearly show the core parts, Figures 1 to 3 Not all clamping fixtures are shown in the image.

[0023] compared to Figure 1 , Figure 3 The plastic structural component 6 is shown.

[0024] The beneficial effects of adopting the above technical solution are as follows: The main shape of the plastic structural component 6 is a through-type shape at both ends. The inner wall stabilizer 5 plays a central support role and serves as a pre-fixation. After the plastic structural component 6 is fitted onto the inner wall stabilizer 5, the outer wall clamping components 3 on both sides move towards each other until they contact the outer wall of the plastic structural component 6, clamping and fixing the outer wall of the plastic structural component 6. However, at this time, the plastic structural component 6 may have a tendency to deform radially inward. Therefore, the hook-shaped segment 103 of the inner wall clamping component 1 extends into the cavity of the plastic structural component 6 and then pulls radially outward until it contacts the inner wall of the plastic structural component 6. Finally, both the inner and outer walls of the plastic structural component 6 are clamped, the overall clamping effect is stable, and the negative impacts such as deformation on the plastic structural component 6 are small.

[0025] In some other embodiments of this utility model, the main body segment 101 is integrally connected to a transverse segment 102 at one end away from the hook-shaped segment 103. The transverse segment 102 is connected to the main body segment 101 in a T-shape and perpendicularly. Each inner wall clamping member 1 is equipped with two springs 2. The two springs 2 are symmetrically distributed on both sides of the main body segment 101. One end of the spring 2 is perpendicularly assembled to the transverse segment 102. The spring 2 is a compression spring.

[0026] The beneficial effects of adopting the above technical solution are: by connecting the main body section 101 and the transverse section 102 in a T-shape vertically and symmetrically assembling two springs 2, the inner wall clamping member 1 is subjected to more balanced force, and the compression spring provides a continuous and stable radial outward elastic force, thereby enhancing the clamping reliability and the positioning accuracy of the structural member 6.

[0027] In other embodiments of this utility model, such as Figure 2As shown, the hook-shaped segment 103 extends vertically downward, and the width of the inner wall clamping member 1 in the hook-shaped segment 103 is smaller than the width of the inner wall clamping member 1 in the main body segment 101.

[0028] The beneficial effects of adopting the above technical solution are: the hook-shaped segment 103 extends vertically downward and its width is smaller than that of the main body segment 101, which makes it easy for the hook-shaped segment 103 to smoothly extend into the cavity of the plastic structural component 6 and effectively contact the inner wall, reducing the risk of interference. At the same time, the larger width of the main body segment 101 ensures the overall structural strength and improves the clamping stability.

[0029] In some other embodiments of this utility model, there are two inner wall clamping members 1, and the arrangement direction of the two outer wall clamping members 3 is perpendicular to the arrangement direction of the two inner wall clamping members 1, that is, they are arranged in a cross shape.

[0030] Figures 1 to 5 Each of the 6 plastic structural components corresponds to only one inner wall clamping component 1, but in reality, two inner wall clamping components 1 can also be arranged.

[0031] The beneficial effects of adopting the above technical solution are: the two inner wall clamping parts 1 and the two outer wall clamping parts 3 are arranged vertically in a cross shape, applying clamping force to the plastic structural part 6 from four directions, making the clamping force distribution more uniform, and further improving the overall stability and processing accuracy of the structural part 6.

[0032] In some other embodiments of this utility model, the inner wall stabilizer 5 includes a T-shaped block 501 located in the cavity of the plastic structural member 6, a hook-shaped segment 103 located between the T-shaped block 501 and the inner wall of the plastic structural member 6, an outer wall clamping member 3 is arranged in the left and right directions of the T-shaped block 501, and an inner wall clamping member 1 is arranged in the front and back directions of the T-shaped block 501, that is, an inner wall clamping member 1 is arranged in the front and back directions of the T-shaped block 501.

[0033] The beneficial effects of adopting the above technical solution are as follows: the T-shaped block 501 provides central pre-limiting support, and the T-shaped design of the T-shaped block 501 allows sufficient space in front and behind to accommodate the movement of the hook-shaped segment 103. The hook-shaped segment 103 is located between the T-shaped block 501 and the inner wall, ensuring effective clamping of the inner wall. At the same time, the clamping direction corresponds to the layout of the T-shaped block 501, making the clamping force distribution balanced and reducing local deformation.

[0034] In other embodiments of this utility model, such as Figure 2 As shown, each outer wall clamp 3 includes two positioning protrusions 303 that can contact the outer wall of the plastic structural member 6, and the two positioning protrusions 303 form an inner recess 304 opposite to each other.

[0035] The beneficial effects of adopting the above technical solution are: the outer wall clamping member 3 contacts the outer wall of the plastic structural member 6 through two positioning protrusions 303, forming an inner recess 304 in the middle. This improves versatility and allows it to adapt to structural members 6 with more shapes.

[0036] In some other embodiments of this utility model, the upper surface of the outer wall clamping member 3 has a groove 301, the bottom surface of the groove 301 has an inclined groove 302, a roller 7 is movably assembled in the inclined groove 302, a central shaft 4 is coaxially assembled in the roller 7, and a frame-shaped member 9 is movably assembled in the two mirror-symmetrically arranged outer wall clamping members 3, and the frame-shaped member 9 is movably assembled with the groove 301.

[0037] The frame component 9 is rectangular in shape, and its two parallel sides are movably assembled with two grooves 301, allowing them to slide against each other.

[0038] The two ends of the groove 301 are not closed, and the groove 301 extends along a straight line.

[0039] The beneficial effects of adopting the above technical solution are as follows: The outer wall clamping member 3 is provided with a groove 301 and an inclined groove 302, which, in conjunction with the roller 7 and the central shaft 4, move under the drive of the frame member 9, making the movement of the outer wall clamping member 3 smoother, reducing friction and wear, and improving clamping efficiency and service life. The inclined groove 302 and the roller 7 transform linear motion in one direction into motion in another perpendicular linear direction, thereby realizing the clamping action of the outer wall clamping member 3.

[0040] In some other embodiments of this utility model, the two mirror-symmetrically arranged outer wall clamping members 3 have their respective inclined grooves 302 and grooves 301 extending at a non-right angle.

[0041] The beneficial effects of adopting the above technical solution are: the inclined grooves 302 and grooves 301 of the two mirror-symmetrical outer wall clamping parts 3 extend at a non-right angle, which optimizes the movement trajectory of the roller 7, ensures that the outer wall clamping parts 3 move more smoothly and stably when they move towards each other, and prevents jamming.

[0042] like Figure 4 , Figure 5 As shown, in some other embodiments of this utility model, a jig plate 8 is provided below the outer wall clamping member 3 and the inner wall clamping member 1. The jig plate 8 has a vertical hollow hole 801, and the inner wall stabilizing member 5 passes through the hollow hole 801. The inner wall stabilizing member 5 has a vertical lifting freedom.

[0043] The beneficial effects of adopting the above technical solution are: the fixture plate 8 is provided with a hollow hole 801, which allows the inner wall stabilizer 5 to be raised and lowered vertically, adapting to plastic structural parts 6 of different heights or sizes, and improving the versatility and operational flexibility of the fixture.

[0044] In some other embodiments of this utility model, the upper surface of the jig plate 8 has a linear guide groove 802, and the outer wall clamping member 3 is movably assembled with the linear guide groove 802. The outer wall clamping member 3 can perform linear reciprocating motion along the length direction of the linear guide groove 802 within the linear guide groove 802.

[0045] The beneficial effect of adopting the above technical solution is that a linear guide groove 802 is provided on the upper surface of the fixture plate 8 to guide the outer wall clamping member 3 to move in a straight line.

[0046] The above embodiments are only for illustrating the technical concept and features of this utility model.
