Description

Technical Field

[0001] The utility model relates to the technical field of feeding, in particular to a punching feeding device for automobile seat accessories. Background Art

[0002] With the rapid development of the automobile industry, the requirements for the efficiency and precision of parts production are increasing day by day. As an important part of automobile interior, the quality of automobile seat accessories is directly related to the comfort and safety of passengers. As a key link in the production of seat accessories, the improvement of the automation and intelligence level of stamping technology is particularly important.

[0003] When using a stamping device to produce automobile seat accessories, the raw material plate is first moved to a conveyor belt using a loading robot arm. The conveyor belt then moves the raw material plate to the bottom of the punching head on the stamping device. The punching head is then moved downward by the stamping device to complete the stamping operation. The loading robot arm used for loading operations in this process can be called a stamping loading device for automobile seat accessories.

[0004] However, before using the feeding robot arm, it is necessary to use a threaded fixing structure to fix the adsorption fixing heads one by one on the feeding robot arm. The fixing process is relatively cumbersome. When the adsorption fixing head installed near the middle position of the feeding robot arm fails and needs to be replaced, it is necessary to remove all the adsorption fixing heads installed on one side of the feeding robot arm one by one before the failed adsorption fixing head can be removed. This installation method makes the replacement process of the adsorption fixing head relatively cumbersome. Therefore, it does not meet the existing needs. In this regard, we propose a stamping feeding device for automobile seat accessories. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] The loading arm 1 (model JSB-Q300), the adsorption head 3 (model GV-084340) and the spring 15 (model JX110) mentioned in the utility model can all be purchased from the market or obtained by private customization.

[0022] See also Figures 1 to 3, the utility model provides an embodiment: a stamping feeding device for automobile seat accessories, including a feeding arm 1, a plurality of adsorption heads 3 are arranged in front of the feeding arm 1, and the rear end surfaces of the plurality of adsorption heads 3 are connected with a disposable fixing mechanism installed inside the feeding arm 1, and the disposable fixing mechanism includes a metal sleeve 2 with the same number as the adsorption heads 3, four tooth row storage grooves 9, four fixed arc-shaped head tooth rows 10 and a synchronous moving mechanism, and the plurality of metal sleeves 2 are movably sleeved on the outer surface of the feeding arm 1, and the surface of the metal sleeve 2 facing the adsorption head 3 is fixed to the adsorption head 3, and an arc-shaped head tooth row 4 is fixedly installed on the upper and lower sides of the metal sleeve 2;

[0023] The four tooth row receiving grooves 9 are respectively located on both sides of the upper and lower end surfaces of the loading arm 1, and the four fixed arc-shaped head tooth rows 10 are respectively located inside the four tooth row receiving grooves 9. The four fixed arc-shaped head tooth rows 10 can be synchronously driven to move up and down through the synchronization mechanism.

[0024] A positioning rail 12 is provided on one side of the tooth row storage groove 9 and is located on the outer surface of the loading arm 1. A positioning slider 13 is fixedly provided at a position inside the metal sleeve 2 corresponding to the positioning rail 12, and the positioning slider 13 is slidably connected to the inside of the positioning rail 12. The positioning slider 13 fixed on the inner wall of the metal sleeve 2 can prevent the metal sleeve 2 from moving up and down, thereby causing the position of the arc-shaped head tooth row 4 fixed on the upper and lower sides thereof to change.

[0025] The synchronous moving mechanism includes a movable rod 11, on the lower side of which a stepper motor 5 is fixedly installed, the output shaft of the stepper motor 5 is connected to a transmission shaft 14 via a coupling, and the lower end surface of the transmission shaft 14 is fixedly connected to a forward and reverse threaded rod 6; when the adsorption head 3 needs to be fixed, the stepper motor 5 is started, and the stepper motor 5 can drive the forward and reverse threaded rod 6 connected to it via the transmission shaft 14 to rotate.

[0026] The threads on both sides of the outer surface of the forward and reverse threaded rod 6 are opposite, and an internal thread sleeve 7 is sleeved on both sides of the outer surface of the forward and reverse threaded rod 6, and the internal thread of the internal thread sleeve 7 matches the external thread of the forward and reverse threaded rod 6; since the threads on both sides of the outer surface of the forward and reverse threaded rod 6 are opposite, when the forward and reverse threaded rod 6 rotates, the two internal thread sleeves 7 respectively sleeved on both sides of the outer surface of the forward and reverse threaded rod 6 will move up and down respectively.

[0027] An L-shaped connecting rod 8 is fixedly connected to both sides of the front and rear end surfaces of the internal threaded sleeve 7. The other ends of the two L-shaped connecting rods 8 fixed to the outer surface of the first internal threaded sleeve 7 from top to bottom are respectively fixed to the fixed arc-shaped head tooth rows 10 inside the two tooth row receiving grooves 9 on both sides of the upper end surface of the loading arm 1, and the other ends of the two L-shaped connecting rods 8 fixed to the outer surface of the second internal threaded sleeve 7 from top to bottom are respectively fixed to the fixed arc-shaped head tooth rows 10 inside the two tooth row receiving grooves 9 on both sides of the lower end surface of the loading arm 1; at this time, the first internal threaded sleeve 7 from top to bottom is moved upward and the second highest internal threaded sleeve 7 is moved downward. As the two internal threaded sleeves 7 move, the fixed arc-shaped head tooth rows 10 respectively connected to the two internal threaded sleeves 7 through the L-shaped connecting rods 8 will move together. With the movement of the head tooth row 10, the four fixed arc-shaped head tooth rows 10 will respectively contact the arc-shaped head tooth rows 4 fixed on the upper and lower sides of the metal sleeve 2, and mesh with them to fix them. When the arc-shaped head tooth row 4 is fixed, the metal sleeve 2 fixed thereto will also be fixed accordingly. When the metal sleeve 2 is fixed, the adsorption head 3 fixed thereto will also be fixed accordingly. Through the above technical scheme, all the adsorption heads 3 can be automatically fixed at one time, thereby reducing the cumbersomeness of the operation when fixing the adsorption heads 3. When the adsorption head 3 needs to be replaced, the engagement between the fixed arc-shaped head tooth row 10 and the arc-shaped head tooth row 4 can be released by driving the first internal threaded sleeve 7 from top to bottom to move downward and the second internal threaded sleeve 7 to move upward through the synchronous moving mechanism, so as to release the fixation of the adsorption head 3 and make the replacement process easier to operate.

[0028] A spring 15 is provided on both sides of the forward and reverse threaded rods 6, and the upper and lower ends of the spring 15 are respectively connected to the two L-shaped connecting rods 8; through the spring force of the spring 15 connected between the two L-shaped connecting rods 8, the L-shaped connecting rod 8 moving outward can be prevented from moving downward without authorization, thereby loosening the fixation of the adsorption head 3.

[0029] The top ends of the teeth on the arc-shaped tooth row 4 and the fixed arc-shaped tooth row 10 are both arc-shaped, and the position of the arc-shaped tooth row 4 corresponds to the position of the fixed arc-shaped tooth row 10; if the fixed arc-shaped tooth row 10 is moved outward, when the teeth on the fixed arc-shaped tooth row 10 and the arc-shaped tooth row 4 are exactly opposite to each other, the arc-shaped tooth row 4 will be slightly pushed through its arc-shaped tooth head ends as the fixed arc-shaped tooth row 10 moves. The above technical solution can avoid the situation where the tooth heads of the two are exactly opposite to each other and cannot engage.

[0030] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
