Description

Technical Field

[0001] This utility model relates to the field of Spindle cable technology, and in particular to a Spindle cable multi-device fixture. Background Technology

[0002] Currently, product fixtures used in Spindle lines (fixed-gun automatic spraying lines) mainly take the form of single-workpiece auxiliary rotation and multi-workpiece simultaneous rotation. Multi-workpiece simultaneous rotation is a type of fixture with multiple components, and its structure is often illustrated in the Chinese utility model "A Novel Headphone Spraying Fixture" (CN215647378U). This fixture includes multiple rotating posts mounted on an automatic conveyor line, a spraying bracket mounted on the posts and rotating with them, multiple first contouring fixtures that can be mounted on the spraying brackets and inserted into the headphone's front cover, and multiple second contouring fixtures that can be mounted on the spraying brackets and inserted into the headphone's rear cover. The first contouring fixture includes a contouring part inside the front cover and a first insertion post; the second contouring fixture includes a contouring part inside the rear cover and a second insertion post; and the spraying bracket is equipped with multiple insertion cylinders for the first or second insertion posts to be inserted into.

[0003] Although multiple workpieces can be mounted simultaneously on a spraying bracket with a contour jig, it can only allow multiple workpieces to rotate with the spraying bracket. The workpieces remain stationary with the spraying bracket. During spraying, local missed spraying or insufficient spraying is easily caused by the obstruction of nearby workpieces, which is not conducive to improving the spraying quality. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a Spindle line multi-axis fixture, comprising a central shaft, a bushing sleeve fitted on the central shaft, the bushing sleeve being rotatably connected to the central shaft, a first driving part connected to the bushing sleeve for rotational driving by a drive mechanism of an external device; the upper end of the central shaft extending upward through the bushing sleeve, and a central gear connected to one end of the central shaft extending upward through the bushing sleeve; a mother disc connected to the upper end of the bushing sleeve, multiple rotating shafts rotatably connected to the mother disc, a sub-gear cooperating with the central gear connected to the rotating shaft, and a workpiece support connected to the upper end of the rotating shaft.

[0006] As a further embodiment of this utility model: the first driving part is a gear connected to the bushing.

[0007] As a further embodiment of this utility model: a protective cover is connected to the mother disc to cover the center gear and the distribution gear, and a shaft hole is opened on the protective cover to allow the upper end of the rotating shaft to pass through.

[0008] As a further embodiment of this utility model: the central shaft is rotatably connected to the external part where it is installed, and a second drive unit is connected to the central shaft for rotational drive by the drive mechanism of the external device.

[0009] As a further embodiment of this utility model: the second driving part is a gear connected to the central shaft.

[0010] As a further embodiment of this utility model: the lower end of the central shaft extends downward through the bushing; the upper spoke of the second drive unit is connected to a second connecting sleeve that is connected to one end of the central shaft extending downward through the bushing; a lower bearing is connected in the shaft hole of the second drive unit; and the central shaft is rotatably connected to the external part where it is installed via the lower bearing.

[0011] As a further embodiment of this utility model: the first driving part is a gear connected to the bushing; the upper spoke of the first driving part is connected to a first connecting sleeve connected to the lower end of the bushing; the second connecting sleeve is located in the shaft hole of the first driving part; and an upper bearing is provided between the first driving part and the second connecting sleeve.

[0012] Compared with the prior art, the beneficial effects of this technical solution are as follows: by rotating the first driving part, the bushing can rotate relative to the central shaft, that is, the mother disc can rotate relative to the central shaft. Through the action of the central gear and the dividing gear, the rotating shaft can rotate accordingly when the mother disc rotates. That is, the workpiece support can simultaneously revolve and rotate. This makes it less likely for the workpiece mounted on the workpiece support to be partially missed or under-sprayed due to the obstruction of adjacent workpieces when it is sprayed on the Spindle line, which is more conducive to improving the spraying quality. In addition, the fixture can install multiple workpieces at the same time, which is beneficial to increasing production capacity.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 A Spindle cable multi-device fixture includes a central shaft 1, a sleeve 2 fitted onto the central shaft 1, the sleeve 2 being rotatably connected to the central shaft 1, and a first drive unit 3 connected to the sleeve 2 for rotational drive by a drive mechanism of an external device. The upper end of the central shaft 1 extends upward through the sleeve 2, and a central gear 4 is connected to one end of the central shaft 1 extending upward through the sleeve. A mother disk 5 is connected to the upper end of the sleeve 2, and multiple rotating shafts 6 are rotatably connected to the mother disk 5. Each rotating shaft 6 is connected to a sub-gear that meshes with the central gear 4, and a workpiece support 8 is connected to the upper end of the rotating shaft 6.

[0022] In this embodiment, the length direction of the rotation center line of the rotating shaft 6 is the same as the length direction of the rotation center line of the bushing 2. For example... Figure 2 As shown, the length direction of the rotation center line of the rotating shaft 6 and the length direction of the rotation center line of the bushing 2 are both vertical.

[0023] By rotating the first drive unit 3, the bushing 2 can rotate relative to the central shaft 1, and the mother disk 5 can rotate relative to the central shaft 1. Through the action of the central gear 4 and the split gear 7, the rotating shaft 6 can rotate accordingly when the mother disk 5 rotates. That is, the workpiece support 8 can simultaneously revolve and rotate. This makes it less likely for the workpiece mounted on the workpiece support 8 to be partially missed or under-sprayed due to the obstruction of adjacent workpieces when it is sprayed on the Spindle line, which is more conducive to improving the spraying quality. In addition, the fixture can install multiple workpieces at the same time, which is beneficial to increasing production capacity.

[0024] In some embodiments, the first drive unit 3 is a gear connected to the bushing 2.

[0025] like Figure 3 As shown, in some embodiments, the drive mechanism for rotating the first drive unit 3 can be a motor drive mechanism with a drive gear 9. The drive gear 9 meshes with the first drive unit 3, and the motor of the motor drive mechanism drives the drive gear 9, thereby causing the first drive unit 3 to rotate.

[0026] In some embodiments, a protective cover 10 is connected to the mother disc 5 to cover the central gear 4 and the auxiliary gear 7. The protective cover 10 has a shaft hole through which the upper end of the rotating shaft 6 passes. The protective cover 10 can effectively prevent the sprayed paint from affecting the gear engagement.

[0027] In this embodiment, the central shaft 1 is rotatably connected to the external part where it is installed, and a second drive unit 12 for being driven by the drive mechanism of the external device is connected to the central shaft 1.

[0028] like Figure 2 As shown, the length direction of the rotation center line of the central shaft 1 is the same as the length direction of the rotation center line of the bushing 2.

[0029] By enabling the rotational drive of the central shaft 1 and the bushing 2, the user can set the rotational speed of the bushing 2 and the central shaft 1 according to their needs. This allows the user to independently adjust the rotational speed of the mother disc 5 (corresponding to the rotational speed of the bushing) and the rotational speed of the rotating shaft 6 (affected by the rotational speed of the central shaft, the number of teeth of the central gear, the number of teeth of the gear, and the rotational speed of the bushing), thus improving adaptability.

[0030] In some embodiments, the central shaft is rotatably connected to an externally mounted component, such as a shaft, on an automated feeder line for the Spindle line.

[0031] like Figure 3 As shown, in some embodiments, the central shaft 1 is rotatably connected to the external connection 13, which is a structural component, such as a shaft, on the spindle cable mounting base 13.

[0032] In some embodiments, the second drive unit 12 is a gear connected to the central shaft 1.

[0033] like Figure 3 As shown, in some embodiments, the drive mechanism for rotating the second drive unit 12 can be a motor drive mechanism with an output gear 15. The output gear 15 meshes with the second drive unit 12, and the motor of the motor drive mechanism drives the output gear 15, thereby causing the second drive unit 12 to rotate.

[0034] In some embodiments, the lower end of the central shaft 1 extends downward through the bushing 2, and the upper spoke of the second drive unit 12 is connected to a second connecting sleeve 16 that is connected to one end of the central shaft 1 that extends downward through the bushing. A lower bearing 17 is connected in the shaft hole of the second drive unit 12, and the central shaft 1 is rotatably connected to the external part where it is installed via the lower bearing 17.

[0035] Preferably, the first drive unit 3 is a gear connected to the bushing 2, the upper spoke of the first drive unit 3 is connected to a first connecting sleeve 11 connected to the lower end of the bushing 2, the second connecting sleeve 16 is located in the shaft hole of the first drive unit 3, and an upper bearing 18 is provided between the first drive unit 3 and the second connecting sleeve 16, which makes the rotation drive more stable.

[0036] In some embodiments, at least one connecting shaft (not shown) is also connected to the mother disk, and a connecting gear is connected to the connecting shaft. The gear meshes with the center gear through at least one connecting gear.

[0037] For example, "the dividing gear meshes with the central gear through a connecting gear" means: the dividing gear meshes with the connecting gear, which in turn meshes with the central gear. This can be used, for example, for adjusting the connection distance.

[0038] In some embodiments, the connecting gear can be a double gear, wherein the intermediate gear meshes with one of the gears in the double gear, and the central gear meshes with the other gear in the double gear. This is used, for example, for setting the speed ratio.

[0039] In some embodiments, the gear meshes directly with the center gear.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
