Technical Field

[0001] This utility model relates to the field of machining fixture technology, and in particular to a decorative strip milling fixture. Background Technology

[0002] With the continuous upgrading of home appliances, their design has become a focus of attention, especially for high-end appliances. Consumers have increasingly higher demands for the aesthetics and decorative appeal of their appliances. Consequently, many home appliances feature attractive metal decorative strips around their cabinet doors or handles. Due to the surface finishing requirements of these strips, surface treatment is essential. To enhance the product's appearance, burrs formed during the stamping process and any excess material left at the edges need to be removed. Milling the workpiece controls the precision of the strip's contour and smooths the edges.

[0003] However, the target trim strips being processed are such as Figure 1 As shown, the workpiece is long and has two U-shaped sections along its length, with the openings of the two U-shaped sections facing each other, making the cross-section of the trim roughly S-shaped. During processing, the far sides of the trim need to be milled to make the trim size uniform, thereby improving the product accuracy. In addition, the milling process can smooth out the burrs generated on the edges during stamping, and the chamfering can also be performed simultaneously.

[0004] In view of the above, it is necessary to propose a trim strip milling fixture to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects in the existing technology and provide a decorative strip milling fixture.

[0006] To achieve the above objectives, the technical solution of this utility model is to design a decorative strip milling fixture, including a base, the base including a support platform, the support platform having at least two sets of positioning blocks, each set of positioning blocks including at least two positioning blocks, each positioning block having a contour support part on one side, the upper end of the contour support part having a protruding support body, and a groove below the support body; The support platform is provided with at least one driving part, and each driving part is provided with a positioning block. The middle part of the positioning block is fixedly connected to the driving part, and both ends of the positioning block extend above the trim strip and have a pressing head protruding towards the trim strip.

[0007] A further preferred technical solution is that a side drive unit is provided on the support platform on one side of the contour support portion of each positioning base block, and a side pressure head is provided on the side drive unit.

[0008] In a further optimized technical solution, an auxiliary base block can be set between any two positioning base blocks in any group.

[0009] A further preferred technical solution is that a stepped hole is provided on the positioning base block corresponding to the bottom surface of the groove. The stepped hole is horizontally set on the positioning base block. An elastic tip is provided in the stepped hole. The elastic tip is a cylindrical part of the step. A spring is fitted on the elastic tip and elastically abuts against the stepped hole.

[0010] A further preferred technical solution is that a stepped hole is also provided on the positioning base block corresponding to the lower side of the groove. The stepped hole is vertically arranged on the positioning base block, and an elastic tip is also provided inside the stepped hole. The elastic tip is also a cylindrical body of the step, and a spring is fitted on the elastic tip to elastically abut against the stepped hole.

[0011] In a further preferred embodiment, the body of the contoured support also has a through hole that communicates with the outer peripheral surface of the protruding support. The advantages and beneficial effects of this utility model are as follows: This utility model forms a clamping and positioning mechanism on both sides of the decorative strip by means of a positioning base block, a positioning pressure head and a side pressure head mechanism. At the same time, it can effectively improve the stability of the clamping and positioning in the vertical and horizontal directions, thereby providing good support for the decorative strip. Under the clamping and fixing, the thinner edge of the decorative strip is easier to mill, and the phenomenon of vibration is effectively avoided. When the trim strip is clamped onto the positioning base block, one U-shaped portion of the trim strip abuts against the support body, while the other U-shaped portion of the trim strip is supported in the groove by two elastic pins, which improves the stability of the support and prevents the occurrence of vibration.

Detailed Implementation

[0013] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0014] like Figure 1-5 As shown, a decorative strip 50 is shaped like... Figure 1 As shown, it is long and narrow, with two U-shaped sections along its length and the openings of the two U-shaped sections facing each other, so that the cross-section of the trim strip 50 is roughly S-shaped. During processing, the far sides of the trim strip need to be milled to make the dimensions of the trim strip 50 uniform, thereby improving the product's precision. In addition, the milling process can smooth out the burrs generated on the edges during stamping, and the chamfering can also be performed simultaneously.

[0015] A trim strip milling fixture includes a base 10, which includes two side plates 11. A support platform 12 is provided on each of the two side plates 11. A U-shaped groove is formed on the body of the side of the two side plates 11 that is furthest from each other. Two sets of positioning blocks 60 are provided on the support platform 12, symmetrically arranged. Each set of positioning blocks 60 includes two positioning blocks 60. A contoured support portion is provided on one side of each positioning block 60. The upper end of the contoured support portion has a protruding support body 61, and a groove 62 is provided below the support body 61. Thus, when one U-shaped portion of the trim strip 50 is inserted into the groove 62 of the two contoured support portions, the support body 61 can be inserted into the other U-shaped portion of the trim strip 50, providing support for the trim strip 50.

[0016] A drive unit 30 is provided on the support platform 12 between the two sets of positioning base blocks 60. The two sets of positioning base blocks 60 provide good space support, allowing the drive unit 30 to be reasonably set up. Moreover, the drive unit 30 is set on the support platform 12, which facilitates the installation and maintenance of the drive unit 12. Furthermore, the drive unit 12 can provide driving force to the positioning base blocks 60 on both sides at the same time, which can balance the torque and improve work efficiency.

[0017] The driving part 30 is provided with a positioning block 40. The middle part of the positioning block 40 is fixedly connected to the driving part 30. Both ends of the positioning block 40 extend above the trim strip 50 and have a pressing head 41 protruding towards the trim strip 50.

[0018] The driving unit 30 applies a driving force to make the positioning block 40 move closer to the positioning base block, and clamps and fixes the trim strip 50 in the clamping space formed between the positioning base block 60 and the positioning block 40. Specifically, in this embodiment, the positioning base block 60 is fixedly set on the support platform 12, which is a fixed block. A contour support is provided on the positioning base block 60, and the contour support fits into the trim strip 50. Thus, the fit is tighter after the positioning block 40 is pressed down, which can provide good support for the trim strip 50. Under clamping and fixing, the thinner edge of the trim strip 50 is easy to mill, effectively avoiding the phenomenon of vibration.

[0019] Furthermore, a side drive unit 20 is provided on the support platform 12 on one side of the contour support portion of the positioning base block 60, and a side pressure head 21 is provided on the side drive unit 20. The side pressure head 21 is pressed against the trim 50 by the side of the trim 50.

[0020] In one embodiment, two sets of positioning base blocks 60 are included, each set of positioning base blocks 60 includes two positioning base blocks 60. A driving part 30 is provided on the support platform 12 between the two sets of positioning base blocks 60 and between the two positioning base blocks 60 in one set. The middle part of the positioning pressure block 40 is fixedly connected to the driving part 30. The two ends of the positioning pressure block 40 extend above the trim strip 50 and have pressure heads 41 protruding towards the trim strip 50. A side driving part 20 is provided on the support platform 12 on one side of a set of positioning base blocks 60. The side driving part 20 is provided with a side pressure head 21. The side pressure head 21 presses against the trim strip 50 from the side of the trim strip 50. This can save the amount of material used in the fixture. After clamping and positioning, the middle part of the trim strip with relatively high strength does not have a vibration phenomenon during the actual milling process because the milling cutter has a single and fixed direction. Therefore, the clamping and positioning of the middle part of the trim strip 50 can be simplified, thereby reducing the cost of the fixture.

[0021] The body of the contour support also has a through hole 65 that communicates with the outer peripheral surface of the support body. The through hole 65 is opened on the body of the contour support from the side away from the support body 61, and extends from the inside to the outer peripheral surface of the support body 61. By injecting high-pressure gas, the trim strip 50 can be easily separated from the support body 61, which facilitates material cutting.

[0022] In another embodiment, two sets of positioning base blocks 60 are included, each set of positioning base blocks 60 includes two positioning base blocks 60. A driving part 30 is provided on the support platform 12 between the two positioning base blocks 60 in the two sets. The middle part of the positioning pressure block 40 is fixedly connected to the driving part 30. The two ends of the positioning pressure block 40 extend above the trim strip 50 and have pressure heads 41 protruding towards the trim strip 50. A side driving part 20 is provided on the support platform on one side of each positioning base block 60. Each side driving part 20 is provided with a side pressure head 21. The side pressure head 21 is pressed against the trim strip 50 by the side of the trim strip 50. This can improve the clamping strength and make the thinner trim strip edge easier to mill under clamping and fixing, effectively avoiding the phenomenon of vibrating cutter.

[0023] Furthermore, an auxiliary base block 70 can be set between any two positioning base blocks 60 in any group. This allows the milling fixture to be used for longer trim strips 50, which can improve the clamping strength and make the thinner trim strip edges easier to mill under clamping and fixing, effectively avoiding the occurrence of vibration.

[0024] Since the positioning base 60 positions and supports the trim strip through the protruding support body 61 and the groove 62, this structure can improve the stability of the support and prevent the occurrence of vibration. However, in actual process, due to the processing error or installation error of the positioning base 60 and the trim strip 50, only the support body 61 or the groove 62 may support the trim strip 50, which reduces the stability of the support. Therefore, the trim strip 50 is supported by two elastic pins. Specifically, a stepped hole is provided on the positioning base 60 corresponding to the bottom surface of the groove 62. The stepped hole is horizontally set on the positioning base 60. An elastic pin 63 is provided in the stepped hole. The elastic pin 63 is a cylindrical step. A spring 64 is fitted on the elastic pin 63 and elastically abuts against the stepped hole. A stepped hole is also provided on the positioning base block 60 corresponding to the lower side of the groove 62. The stepped hole is vertically set on the positioning base block 60. An elastic tip 63 is also provided in the stepped hole. The elastic tip 63 is also a cylindrical body with a step. A spring 64 is fitted on the elastic tip 63 and elastically abuts against the stepped hole. In this way, when the trim 50 is clamped on the positioning base block 60, one U-shaped part of the trim 50 abuts against the support body 61, while the other U-shaped part of the trim 50 is supported by two elastic pins 63 in the groove 62, which improves the stability of the support and prevents the vibration phenomenon.

[0025] Furthermore, the drive unit 30 is a pneumatic or hydraulic telescopic cylinder, which includes a cylinder body and a drive rod. The cylinder body is fixedly mounted on the support platform 12, and the drive rod is connected to the positioning block 40. In actual use, the drive rod of the telescopic cylinder extends upward, thereby lifting the positioning block 40, opening the clamping and positioning area, and then placing the trim strip 50 into the corresponding clamping position. Then, the drive unit drives the positioning block 40 to press down to complete the clamping and positioning of the trim strip 50.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
