Description

Technical Field

[0001] The utility model belongs to the technical field of steering wheel production, and relates to a crimping device, in particular to a crimping device used for crimping a speaker contact onto a steering wheel frame when producing a steering wheel. Background Art

[0002] The horn is a car's sound signal device. During the driving process of the car, the driver sends out necessary sound signals according to needs and regulations to warn pedestrians and attract the attention of other vehicles to ensure traffic safety. It is also used to urge driving and transmit signals.

[0003] Car horns are divided into two types according to sound power: air horns and electric horns. Electric horns use electromagnetic attraction to vibrate metal diaphragms to produce sound, and are widely used in cars. Car electric horns are composed of iron cores, magnetic coils, contacts, armatures, diaphragms, etc. When the driver presses the horn switch, the current passes through the contacts and the coil, thereby triggering its generation mechanism. Among them, the contacts need to be crimped onto the steering wheel frame.

[0004] At present, workers usually crimp the contacts one by one on the designated positions of the steering wheel frame. This method is inefficient and it is also easy for individual contacts to not be crimped in place, resulting in product quality problems. Utility Model Content

[0005] In order to solve the above deficiencies in the prior art, the utility model aims to provide a steering wheel horn contact crimping device to avoid the inefficiency caused by multiple crimping by manpower and the possible problem of inadequate crimping.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A steering wheel horn contact crimping device comprises a frame, a crimping unit and a positioning unit; the frame comprises a base and a top seat erected above the base through a support column, and an operating space is formed between the base and the top seat; the crimping unit is assembled on the top seat, and the positioning unit is assembled on the base, and the working end of the crimping unit is vertically downward and toward the positioning unit.

[0008] As defined in the present utility model, the crimping unit includes a linear drive assembly fixed on the upper surface of a top seat and a crimping tool threadedly connected to the power output end of the linear drive assembly; a through hole is opened at the center position of the top seat, and the power output end of the linear drive assembly passes through the through hole and vertically downward, so that the crimping surface of the crimping tool threadedly connected to the power output end of the linear drive assembly faces the positioning unit.

[0009] As a further limitation of the present invention, the crimping tool comprises a fixing block threadedly connected to the power output end of the linear drive assembly and a plurality of crimping posts fixed on the fixing block, wherein the distribution positions of the plurality of crimping posts correspond to the installation positions of the horn contacts of the steering wheel frame positioned on the positioning unit;

[0010] The bottom surface of the crimping column facing the positioning unit forms a crimping surface of the crimping tool.

[0011] As another limitation of the present invention, the positioning unit is a positioning tool that is adhesively fixed to the base.

[0012] As a further limitation of the present invention, a fixing hole is provided at the center of the positioning tool, and a plurality of positioning columns are fixedly provided on the upper surface of the positioning tool; the distribution positions of the plurality of positioning columns correspond to the positions of the positioning holes on the steering wheel frame.

[0013] As a further limitation of the present invention, an upper surface of the positioning tool is provided with a guide groove extending from one side toward the fixing hole.

[0014] As another limitation of the present invention, two ends of the support column are respectively threadedly connected to the base and the top seat.

[0015] Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0016] (1) The utility model designs a semi-automatic steering wheel contact crimping device, which can crimp all the contacts on the steering wheel in place in one action, solving the problem of low efficiency caused by workers crimping one by one for many times, and also avoiding the problem of inadequate crimping that may occur when the contacts are crimped one by one. The utility model can crimp all the contacts on the steering wheel frame at the same time, ensuring the consistency of the crimping degree, improving production efficiency and ensuring the product qualification rate.

[0017] (2) The crimping tool in the utility model is threadedly assembled on the power output end of the linear drive assembly, and the positioning tool is bonded and fixed on the base. When the model of the steering wheel frame that needs to crimp the contact point changes, the corresponding crimping tool and positioning tool can be replaced, which has good applicability.

[0018] (3) In the utility model, a guide groove is provided on the side of the positioning tool close to the worker's operation. When placing the steering wheel frame, the steering wheel frame only needs to be pushed along the guide groove until the center of the steering wheel frame reaches the fixing hole, and the positioning of the steering wheel frame on the positioning tool can be completed. The operation is simple and can effectively improve work efficiency.

[0019] (4) The support column in the frame of the utility model is threadedly connected between the base and the top seat. When the steering wheel frame that needs to press the contact point is large, the distance between the base and the top seat can be adjusted by the thread so that the operating space formed can meet the required stroke for crimping. In addition, by replacing the support column with a longer size, the operating space formed between the base and the top seat can meet the production needs.

[0020] In summary, the utility model effectively solves the inefficiency and quality problems of the horn contact crimping process during steering wheel production, and is suitable for use in crimping horn contacts on steering wheel frames of various models. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and understand the present invention, and are not used to limit the present invention.

[0029] This embodiment discloses a steering wheel horn contact crimping device, including a frame, a crimping unit and a positioning unit.

[0030] like Figure 1As shown, the frame includes a base 1, a top seat 2 and a support column 3. The two ends of the support column 3 are respectively connected to the base 1 and the top seat 2 by threads, so that the top seat 2 is erected above the base 1 through the support column 3. Between the base 1 and the top seat 2 is an operating space for crimping contacts. When the steering wheel frame is large in size and the operating space cannot complete the contact crimping work, the distance between the base 1 and the top seat 2 can be adjusted by threads to make the formed operating space larger until the required stroke for crimping is met. Of course, the operating space can also be increased by replacing the support column 3 with a larger size to meet the crimping installation of the speaker contacts on the steering wheel frame.

[0031] The crimping unit includes a linear drive assembly 4 fixed on the upper surface of the top seat 2 and a crimping tool 5 threadedly connected to the power output end of the linear drive assembly 4, wherein the crimping tool 5 serves as the working end of the crimping unit, vertically downward and toward the positioning unit on the base 1. The linear drive assembly 4 can be a pneumatic cylinder or an oil cylinder, and in this embodiment, it is an oil cylinder. Figure 2 As shown, the crimping tool 5 includes a fixing block 51 threadedly connected to the power output end of the linear drive assembly 4 and a crimping column 52 fixed on the fixing block 51 corresponding to the installation position of the horn contact on the steering wheel frame to be crimped. The crimping column 52 faces the bottom surface of the positioning tool 6 to form the crimping surface of the crimping tool 5. In actual production, the linear drive assembly 4 drives the crimping tool 5 to move downward, so that the crimping surface contacts the contact and presses downward until it is crimped to the specified position on the steering wheel frame.

[0032] It is necessary to add here that Figure 1 As shown, a through hole is opened at the center of the top seat 2, and the power output end of the linear drive assembly 4 passes through the through hole and vertically downward, so that the crimping surface of the crimping tool 5 threadedly connected to the power output end faces the positioning unit on the base 1.

[0033] The positioning unit is a positioning fixture 6, which is temporarily fixed on the base 1 by gluing. Figure 3 As shown, a fixing hole 62 is provided at the center of the positioning tool 6, and an introduction groove 61 is provided on the upper surface of the positioning tool 6 from one side to the fixing hole, and a plurality of positioning posts 63 are also provided on the upper surface of the positioning tool 6, and the distribution positions of the positioning posts 63 correspond to the positions of the positioning holes on the steering wheel skeleton. In this embodiment, the positioning posts 63 include four cylindrical positioning posts and one rectangular positioning post. When positioning the steering wheel skeleton to be crimped, the steering wheel skeleton is pushed along the introduction groove 61, and when the center of the steering wheel skeleton reaches the position of the fixing hole 62, the positions of the positioning holes on the steering wheel skeleton also correspond to the positions of the positioning posts 63 on the positioning tool 6. At this time, the steering wheel skeleton loses its supporting force because the center of the steering wheel skeleton reaches the fixing hole 62. At this time, the steering wheel skeleton moves downward under the influence of gravity, so that the positioning hole is sleeved on the positioning post 63, and the steering wheel skeleton is positioned.

[0034] It should be added here that the positioning holes on the steering wheel frame in this embodiment refer to the bolt holes or equipment installation grooves and positioning grooves originally used for subsequent assembly on the steering wheel frame.

[0035] When using this embodiment, first place the positioning jig 6 on the base 1, and adjust the position of the positioning jig 6 according to the position of the crimping jig 5, so that after the steering wheel skeleton to be crimped is positioned on the positioning jig 6, the installation position of its horn contact corresponds to the position of the crimping column 52 on the crimping jig 5. After the position adjustment of the positioning jig 6 is completed, use a glue gun to glue the positioning jig 6 to be temporarily fixed on the base 1. Then place the steering wheel skeleton to be crimped on the positioning jig 6, and place the horn contact at the installation position; after confirming that the position is correct, start the linear drive component 4, the linear drive component 4 drives the crimping jig 5 to move vertically downward, press the horn contact until it is crimped to the specified position, then the linear drive component 4 drives the crimping jig 5 to lift up, take out the steering wheel skeleton, and the crimping work is completed.

[0036] It should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
