Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, in particular to a fixture device. Background Art

[0002] Related technologies point out that most of the current fixture designs are for fixed products, and the number of fixtures is basically equal to the number of products. As a result, firstly, the fixture reuse rate is extremely low, resulting in a large amount of fixture waste; secondly, the design cycle and test verification cycle of new fixtures prolong the entire production preparation cycle; thirdly, as the number of product types increases, the number of fixtures also increases, making storage and maintenance difficult.

[0003] The existing fixture design is targeted based on product characteristics such as product installation holes, installation positions, and installation angles. The design is then subjected to modal analysis to meet fundamental frequency requirements. Finally, the fixture is manufactured and tested. The fixture is considered qualified after the test results meet relevant test standards.

[0004] The existing technical solutions require repeated design, modal analysis, communication and confirmation of design details for various types of products, and a new design is required for each type of product. In the process of product updates and iterations, if the installation angle, installation hole position, or installation position changes, the fixture needs to be redesigned, and the usability is poor. The existing technical solutions have poor universality between different versions of the same type of products. For example, the fixtures used for three-ear TBOX and four-ear TBOX are different, resulting in two or even more sets of fixtures for one type of product. Each set of fixtures in the existing technical solutions needs to be tested to confirm whether they meet the DV test requirements, which is time-consuming. The existing technical solutions as a whole are time-consuming, labor-intensive, material-intensive, and costly, have poor flexibility, and are difficult to store and maintain, which is not conducive to improving project efficiency.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0036] Reference below Figure 1-14B A clamp device 100 according to an embodiment of the present invention is described.

[0037] like Figure 1 and Figure 3 As shown, the clamp device 100 according to the embodiment of the utility model includes: a base 1, a ball seat 2, a mounting seat 4 and a bracket assembly 5.

[0038] Specifically, the clamp device 100 is arranged on the vibration workbench, and the clamp device 100 includes: a base 1, a ball seat 2, a mounting seat 4 and a bracket assembly 5, the base 1 is formed with a receiving cavity, the ball seat 2 is rotatably arranged in the receiving cavity, the mounting seat 4 is arranged on the ball seat 2, a mounting portion is formed on the mounting seat 4, and the bracket assembly 5 is arranged on the mounting seat 4, and the mounting portion is suitable for detachably connecting with different types of bracket assemblies 5. Therefore, the clamp device 100 has strong versatility and ingenious structural design.

[0039] According to the clamp device 100 of the embodiment of the utility model, by providing different types of bracket assemblies 5 detachably connected to the mounting seat 4, the size range of the clamp device 100 for clamping the electronic control unit or other types of parts is expanded, the repeated design of the clamp is avoided, and the cost of clamp design and manufacturing is saved.

[0040] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the bracket assembly 5 includes: at least two first brackets 51, each of which is detachably connected to the mounting portion, and the electronic components or parts are fixed on the first brackets 51. The detachable connection improves the ability of the bracket assembly 5 to be quickly replaced and adjusted without the need for complex tools or a lot of time, greatly improving work efficiency and flexibility, and achieving processing accuracy and wide adaptability to different objects to be measured.

[0041] In some embodiments of the present invention, the mounting portion has a first mounting hole 41 extending in the horizontal direction, and first fixing holes 511 are formed at both ends of the first bracket 51. The first bracket 51 and the mounting seat 4 are connected by fasteners 6 passing through the first fixing holes 511 and the first mounting holes 41. The first bracket 51 is formed with a connecting hole 512, and the connecting hole 512 is used to fix the measured object 200. Therefore, the assembly method of the first bracket 51 and the mounting seat 4 is simple and reliable. Figure 3 and Figure 4 As shown, the first mounting holes 41 are long strip holes, which facilitates the adjustment of the spacing distance between the first brackets 51 and further improves the wide adaptability to different objects to be measured.

[0042] In other embodiments of the present invention, the bracket assembly 5 includes: a second bracket 52 and at least two first brackets 51, at least one of the at least two first brackets 51 is detachably connected to the mounting portion, the second bracket 52 is detachably connected to the mounting portion, and at least another of the at least two first brackets 51 is detachably connected to the second bracket 52. Figure 1 and Figure 2 As shown, one of the two first brackets 51 is detachably connected to the mounting base 4, and the other of the two first brackets 51 is detachably connected to the second bracket 52. Thus, the vertical placement requirement of the measured object is achieved, and the ability of the bracket assembly 5 to be quickly replaced and adjusted is improved without complicated tools or a lot of time.

[0043] Furthermore, the mounting portion has a first mounting hole 41 extending in the horizontal direction and a second mounting hole 42 extending in the vertical direction, the second bracket 52 is formed with a second fixing hole 522, and the second bracket 52 is connected to the mounting seat 4 by a fastener 6 passing through the second fixing hole 522 and the first mounting hole 41; first fixing holes 511 are formed at both ends of the first bracket 51, and the first bracket 51 and the mounting seat 4 are connected by fasteners 6 passing through the first fixing hole 511 and the first mounting hole 41, a third mounting hole 521 extending in the vertical direction is formed on the second bracket 52, the first bracket 51 and the second bracket 52 are connected by fasteners 6 passing through the first fixing hole 511 and the third mounting hole 521, and the first bracket 51 is formed with a connecting hole 512, and the connecting hole 512 is used to fix the measured component 200. Therefore, the assembly method of the first bracket 51 and the second bracket 52 with the mounting base 4 is simple and reliable. As shown in the figure, the first mounting hole 41, the second mounting hole 42 and the third mounting hole 521 are all long holes, which is convenient for adjusting the spacing distance between the first brackets 51, further improving the wide adaptability to different objects to be measured.

[0044] Furthermore, the connection hole 512 is also formed as a long strip-shaped hole, so as to facilitate adjustment of the fixing position of the device under test 200 according to the size of the device under test 200 .

[0045] In some embodiments of the utility model, the base 1 includes: a base body and a ball seat cover 3, the base body is formed with a plurality of fixing grooves 12, each fixing groove 12 extends in the circumferential direction of the base body as an arc groove, and the plurality of fixing grooves 12 are arranged in groups of two, and the centers of the plurality of groups of fixing grooves 12 do not overlap. In detail, the groove spacing of the fixing grooves 12 is designed according to the installation hole distance of the vibration worktable, and the base 1 is fixed on the vibration worktable through the fixing grooves 12 by fasteners 6. Since the centers of the fixing grooves 12 do not overlap (i.e., the fixing grooves 12 are eccentrically arranged), the base 1 can rotate at will, and it is ensured that the eight installation points cannot rotate after installation, which not only increases the fixing ability of the base 1, but also increases the flexibility of the base 1 in adjusting the circumference.

[0046] In some embodiments of the utility model, a boss 11 is formed on the seat body, a ball groove 111 is formed in the boss 11, the ball seat 2 is arranged in the ball groove 111, and the ball seat cover 3 is connected to the periphery of the boss 11. Therefore, the structure of the base 1 is simple, easy to produce and assemble, and the connection method of the ball seat cover 3 and the base 1 is simple, which improves the production efficiency.

[0047] In some embodiments of the utility model, the inner peripheral wall of the ball seat cover 3 and the inner peripheral wall of the ball groove 111 define a receiving cavity, the peripheral wall of the receiving cavity is formed into a spherical surface, the ball seat 2 is arranged in the receiving cavity, the receiving cavity is configured to wrap at least a portion of the ball seat 2, and the peripheral wall of the receiving cavity is in contact with the surface of the ball seat 2. Specifically, according to the position and angle of the test piece 200, the sandblasted ball seat 2 is placed in the ball groove 111 of the base 1 according to the calculated position in advance, and the ball seat cover 3 is covered.

[0048] In some embodiments of the utility model, the ball seat cover 3 includes a fixing portion 31 and a wrapping portion 32. The fixing portion 31 is formed in an annular shape and is matched and connected with the periphery of the boss 11. One side edge of the wrapping portion 32 is connected with the inner periphery of the fixing portion 31. In the direction from one end of the wrapping portion 32 toward the other end, the height of the wrapping portion 32 first gradually increases and then gradually decreases. In this way, the 360° horizontal rotation angle and 45° vertical swing angle of the ball seat 2 are achieved, so that the clamp device 100 can be adjusted in all directions within 360° without dead angles, thereby improving the adaptability of the clamp device 100.

[0049] In some embodiments of the utility model, the mounting seat 4 is connected to the ball seat 2 by a fastener 6. Specifically, according to the position and angle of the measured object 200, the sandblasted ball seat 2 is placed in the ball groove 111 of the base 1 according to the calculated position in advance, and the ball seat cover 3 is covered, and the assembly size ensures that the clearance between the fixing portion 31 of the ball seat cover 3 and the peripheral edge of the boss 11 of the base 1 is matched to ensure the stability of the ball seat 2 after being fixed by the fastener 6.

[0050] To summarize, whether to install the first bracket 51 is determined based on the position and angle of the device under test 200. For situations where the first bracket 51 is not used (i.e., the device under test 200 needs to be placed horizontally), the device under test 200 is first installed on the fourth slot of the second bracket 52 through the fastener 6, and then the second bracket 52 is installed in the mounting slot of the mounting seat 4, and then the device under test 200 is installed on the second bracket 52; for situations where the first bracket 51 is needed (i.e., the device under test 200 needs to be placed vertically), the device under test 200 is first installed on the fourth slot of the second bracket 52 through the fastener 6, and then the second bracket 52 is installed on the first bracket 51 through the fastener 6, and the first bracket 51 is fixed to the mounting seat 4 through the fastener 6 passing through the first slot and the mounting slot. This greatly increases the ability of the fixture device 100 to adapt to the size, position and mounting holes of the measured component. The position of the measured component 200 can be fully covered by the forward and reverse installation method, and the combined installation of complex components is realized. In addition, the design of the fixed bracket assembly 5 is based on the topological optimization of modal analysis. The slot and shape design and the hollow design of the ball seat 2 can not only meet the fundamental frequency requirements but also achieve the weight reduction effect.

[0051] Furthermore, if Fig.14AThe dot shown is the center point of the ball seat 2, a is the distance from the center of the ball to the edge of the ball seat 2, b is the vertical distance from the upper edge of the ball seat 2 to the screw mounting surface of the ball seat cover 3, and (90°-θ) is the maximum angle that the ball seat 2 can rotate.

[0052] According to the 3D design, in order to make the fixture function meet the requirements of sample installation without dead angle, θ needs to be less than or equal to 45°, that is, FIG. 14A to FIG. 14B In this state, the rotation angle of the ball seat 2 is greater than or equal to 45°.

[0053] Because tanθ=b / a

[0054] So θ = arctan(b / a)

[0055] Therefore, as long as arctan(b / a)≤45°, the fixture design can meet the requirement of installing the sample without dead angles.
