Description

Technical Field

[0001] The utility model relates to the field of automation, and particularly refers to a jig for pressing and installing the clamping feet of a car high - pitched horn cover. Background Art

[0002] The car horn cover assembly is a part of the door panel assembly. Generally speaking, it mainly allows the volume of the sound source of the speaker to pass through and transmit to the whole carriage, and at the same time plays a role of coordinated decoration in combination with the overall shape and style of the vehicle. For example, a car bass horn cover installation structure disclosed in the prior art 201120128716.1, in which the horn cover and the door trim are clamped through multiple sets of clamping platforms and clamping grooves.

[0003] At present, the clamping of the horn cover and the door trim is either by manually bending the clamping platforms one by one with tools or by automatically bending the clamping platforms through equipment. However, the former not only has low work efficiency and high labor intensity, but also the installation quality cannot be guaranteed. The latter, such as a multi - station metal trim pressing equipment for car interior and exterior parts with easy mold replacement disclosed in the prior art 202210608575.6, during operation, the bending mechanism is driven by a lifting mechanism to move downward until the bending mechanism approaches multiple clamping feet on the horn cover, then the bending mechanism bends multiple clamping feet on the horn cover simultaneously, and finally the profiling mold is lifted by the lifting mechanism to flatten the bent clamping feet at the same time. Since the bending mechanism and the lifting mechanism need to be driven by cylinders, not only does it make the structure more complex and not conducive to miniaturization, but also greatly increases the production cost. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a jig for pressing and installing the clamping feet of a car high - pitched horn cover in order to overcome the deficiencies of the prior art.

[0005] To achieve the above - mentioned purpose, the technical solution adopted by the utility model is: a jig for pressing and installing the clamping feet of a car high - pitched horn cover, which includes a lower template, at least one profiling mold arranged on the lower template for placing the product, multiple sets of bending components arranged around the profiling mold and corresponding to the placement of the clamping feet, an upper template horizontally arranged above the profiling mold, multiple elastic pressing columns vertically arranged on the upper template for fixing the product, multiple driving columns vertically arranged on the upper template for driving the bending components to translate to bend the clamping feet, and multiple flattening columns vertically arranged on the upper template for flattening the bent clamping feet;

[0006] Each of the bending components includes a base arranged on the lower template, a slider horizontally slidably arranged on the base, a pressing head arranged at the head of the slider for bending the clamping feet, and a return spring arranged between the slider and the profiling mold; the tail of the slider is triangular;

[0007] A bent portion corresponding to the tail of the slider is provided at the lower end of the driving column; when the bent portion just contacts the upper inclined surface of the tail of the slider during downward pressing, it can drive the slider to drive the pressing head to bend the locking leg by overcoming the elastic force of the return spring; when the bent portion disengages from the upper inclined surface of the tail of the slider, the slider returns to the initial position under the elastic force of the return spring;

[0008] The lower end of the flattening column is higher than the bent portion; during the downward pressing of the driving column, the slider returns to the initial position, and then the flattening column flattens the bent locking leg.

[0009] Preferably, a roller is provided on the bent portion; when the driving column presses downward, it contacts the upper inclined surface of the tail of the slider through the roller.

[0010] Preferably, the slider is made of wear-resistant material.

[0011] Preferably, a bearing plate is provided between the upper template and the profiling die; the bearing plate is connected to the upper template through multiple connecting columns; both the driving column and the flattening column are provided on the bearing plate.

[0012] Preferably, the upper end of the flattening column passes through the bearing plate, and nuts are installed on both the upper and lower sides of the bearing plate for the flattening column.

[0013] Preferably, multiple groups of limiting components are provided between the upper template and the lower template.

[0014] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0015] When the upper template presses downward in the utility model, it can not only drive the bending assembly to translate to bend the locking leg through the driving column, but also flatten the bent locking leg through the flattening column, without the need for an additional power source to drive, and has the advantages of simple and compact structure, low production cost, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Appendix Figures 1 - 5 The present utility model relates to a clamping and pressing tool for the clamping feet of an automotive high - pitched horn cover, which includes a lower template 1, two profiled dies 2 arranged on the lower template 1 for placing products, multiple groups of bending assemblies 3 arranged around the profiled dies 2 and corresponding to the placement of the clamping feet 91, an upper template 4 horizontally arranged above the profiled dies 2, multiple elastic pressing columns 5 vertically arranged on the upper template 4 for fixing the products, multiple driving columns 6 vertically arranged on the upper template 4 for driving the bending assemblies 3 to translate and bend the clamping feet 91, and multiple flattening columns 7 vertically arranged on the upper template 4 for flattening the bent clamping feet 91;

[0025] Each of the bending assemblies 3 includes a base 31 arranged on the lower template 1, a slide block 32 horizontally slidably arranged on the base 31, a pressing head 33 arranged at the head of the slide block 32 for bending the clamping feet 91, and a return spring 34 arranged between the slide block 32 and the profiled die 2; the tail of the slide block 32 is triangular;

[0026] The lower end of the driving column 6 is provided with a bending part 61 corresponding to the tail of the slide block 32;

[0027] The lower end of the flattening column 7 is higher than the bending part 61.

[0028] During operation: First, the operator places the horn cover 9 in the profiling die 2 for positioning; then, the equipment is started, and the upper template 4 is driven to descend by the lifting mechanism. During the descent, multiple elastic pressing columns 5 first come into contact with the horn cover 9 to fix the horn cover 9 in the profiling die 2 and prevent the horn cover 9 from shifting, which may affect the subsequent pressing of the card feet 91. Since the elastic pressing columns 5 are elastic, after the elastic pressing columns 5 abut against the horn cover 9, the lifting mechanism can still continue to drive the upper template 4 to descend. At the same time, since the tail of the slider 32 is triangular, multiple bending parts 61 can overcome the elastic force of the return spring 34 through the upper inclined surface 321 of the tail of the slider 32 to drive the slider 32 to drive the pressing head 33 to bend the card feet 91. When the bending parts 61 are pressed down and separated from the upper inclined surface 321 of the tail of the slider 32, the slider 32 returns to its initial position under the elastic force of the return spring 34. At this time, the driving column 6 will not interfere with the reset of the slider 32. Finally, the lifting mechanism continues to drive the upper template 4 to descend, and the bent card feet 91 are flattened by multiple flattening columns 7 to complete the pressing of the card feet 91.

[0029] Further, as Figure 3 shown, the bending part 61 is provided with a roller 62; when the driving column 6 presses down, it contacts the upper inclined surface 321 of the tail of the slider 32 through the roller 62, which can reduce wear and improve the service life.

[0030] Further, the slider 32 is made of wear-resistant material, which can further reduce wear and improve the service life.

[0031] Further, as Figure 1 shown, a bearing plate 41 is arranged between the upper template 4 and the profiling die 2; the bearing plate 41 is connected to the upper template 4 through four connecting columns 42; the driving column 6 and the flattening columns 7 are both arranged on the bearing plate 41. By adding the bearing plate 41 in the present utility model, the heights of the driving column 6 and the flattening columns 7 can be reduced, so that the driving column 6 and the flattening columns 7 are not easily deformed during the downward pressing process, and the pressing accuracy is improved.

[0032] Further, as Figure 3 shown, the upper end of the flattening column 7 passes through the bearing plate 41, and nuts 71 are installed on both the upper and lower sides of the bearing plate 41 for the flattening column 7. In the present utility model, the height of the flattening column 7 can be adjusted through the upper and lower two nuts 71, which greatly reduces the processing accuracy and saves production costs.

[0033] Further, as Figure 1 shown, multiple groups of limiting components 8 are arranged between the upper template 4 and the lower template 1 to play a safety protection role and avoid damage to the tooling when the lifting mechanism fails and presses down.

[0034] The above are only specific application examples of the present utility model, and do not constitute any limitation to the protection scope of the present utility model. Any technical solutions formed by equivalent transformation or equivalent substitution fall within the protection scope of the rights of the present utility model.
