Description

Technical Field

[0001] The present invention relates to a multi-station turntable positioner, belonging to the technical field of positioners. Background Art

[0002] Automated production is production carried out using automated technology. It has brought extremely profound impacts to human society. The most important one is that it has greatly improved social labor productivity and enhanced the ability of humans to transform nature. According to the degree of automation, it can be divided into semi-automated production and fully automated production. The former partially uses automated technology in the production process and is partially operated manually; the latter is all processes of the entire production process, including loading, unloading, packaging, transportation, etc., without direct human participation in operation, but only indirectly supervising the machine work. A turntable positioner is required during automated production.

[0003] In traditional semi-automated production, a turntable positioner is not used. When processing polyhedral parts or multiple materials, the position of the material needs to be adjusted multiple times. The process of the operator adjusting the position of the material by himself is rather cumbersome, and the low-precision rotational positioning during adjustment is also prone to angular deviation, causing assembly interference problems.

[0004] Therefore, a multi-station turntable positioner is proposed. Summary of the Invention

[0005] In view of this, the present invention provides a multi-station turntable positioner to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0006] The technical solution of the present invention is realized as follows: A multi-station turntable positioner includes a housing. At the bottom of the inner cavity of the housing, a worm gear is movably connected through a rotating shaft. On the left and right sides of the inner cavity of the housing, equidistant blocks are both connected by bolts in a threaded manner. A transmission shaft is movably connected to the inner sides of the two equidistant blocks. A large-lead worm thrust sleeve is sleeved on the surface of the transmission shaft. The surface of the worm gear is movably connected with rollers. The size of the rollers matches the thread pitch on the surface of the large-lead worm thrust sleeve. Circular nuts are threadedly connected to the surfaces of the two equidistant blocks. The transmission shaft is connected to an external driving device.

[0007] Further preferably, screw grooves are provided at the tops of the worm gears, and positioning pin grooves are provided at the tops of the worm gears.

[0008] Further preferably, slot holes are provided at the bottoms of the worm gears, and the eight slot holes are arranged equidistantly in the circumferential direction.

[0009] Due to the adoption of the above technical solutions in the embodiments of the present invention, it has the following advantages:

[0010] 1. The present invention is provided with a housing, a worm wheel, an equidistant block, a transmission shaft, a large lead worm thrust sleeve, and rollers. By means of an external driving device, the transmission shaft rotates, driving the large lead worm thrust sleeve to rotate, thereby causing the large lead worm thrust sleeve to drive the rollers to displace, and then realizing the rotation of the worm wheel. By intermittently rotating the worm wheel, it is convenient for the worm wheel to drive an external turntable to rotate intermittently synchronously, so that it is convenient to drive materials to move intermittently in the circumferential direction, thereby realizing the adjustment of the position of the materials, improving the convenience of processing the materials during automated processing, and facilitating the operation of the operator.

[0011] 2. The present invention is provided with a spiral groove and a positioning pin groove, which can facilitate the connection of an external multi-station turntable to the worm wheel through the cooperation of the positioning pin and the bolt, thereby realizing the disassembly and assembly of the external multi-station turntable.

[0012] The above summary is only for the purpose of the specification and is not intended to be limiting in any way.

[0020] In the following text, only some exemplary embodiments are briefly described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present invention. Therefore, the accompanying drawings and description are considered to be exemplary in nature rather than restrictive.

[0021] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] Embodiment 1

[0023] As Figures 1-5 shown, the embodiment of the present invention provides a multi-station turntable positioner, including a housing 1. The bottom of the inner cavity of the housing 1 is movably connected with a worm gear 2 through a rotating shaft. On both the left and right sides of the inner cavity of the housing 1, equal-spacing blocks 3 are threadedly connected through bolts. A transmission shaft 4 is movably connected to the inner sides of the two equal-spacing blocks 3. A large-lead worm thrust sleeve 5 is sleeved on the surface of the transmission shaft 4. Rollers 6 are movably connected to the surfaces of the worm gears 2. The size of the rollers 6 matches the thread pitch on the surface of the large-lead worm thrust sleeve 5. Round nuts 10 are threadedly connected to the surfaces of the two equal-spacing blocks 3. The transmission shaft 4 is connected to an external driving device.

[0024] By providing the housing 1, worm gear 2, equal-spacing blocks 3, transmission shaft 4, large-lead worm thrust sleeve 5, and rollers 6, the transmission shaft 4 is rotated by an external driving device. The transmission shaft 4 drives the large-lead worm thrust sleeve 5 to rotate, so that the large-lead worm thrust sleeve 5 drives the rollers 6 to displace, and then the rotation of the worm gear 2 is realized. By intermittently rotating the worm gear 2, it is convenient for the worm gear 2 to drive the external turntable to rotate synchronously and intermittently, so that it is convenient to drive the material to move intermittently in the circumferential direction, thereby realizing the adjustment work of the material position, improving the processing convenience of the material during automated processing, and facilitating the operation of the operator.

[0025] Embodiment 2

[0026] As Figures 1-3 shown, in one embodiment, screw grooves 7 are provided at the tops of the worm gears 2, positioning pin grooves 8 are provided at the tops of the worm gears 2, and slot holes 9 are provided at the bottoms of the worm gears 2. The eight slot holes 9 are equally spaced in the circumferential direction.

[0027] By providing the screw grooves 7 and positioning pin grooves 8, it is convenient for the worm gear 2 to be connected to the external multi-station turntable through the cooperation of the positioning pin and the bolt, thereby realizing the disassembly and assembly work of the external multi-station turntable.

[0028] When the present invention is in operation: First, an external driving device drives the transmission shaft 4 to rotate. At this time, the transmission shaft 4 synchronously drives the large lead worm thrust sleeve 5 to rotate. As the large lead worm thrust sleeve 5 rotates, the large lead worm thrust sleeve 5 pushes the roller 6 to displace in the circumferential direction. At this time, the large lead worm thrust sleeve 5 generates rotation. As the large lead worm thrust sleeve 5 displaces in the circumferential direction, the worm wheel 2 synchronously generates rotation. Since the lead of the large lead worm thrust sleeve 5 is the center distance between the centers of two adjacent rollers 6 on the surface of the worm wheel 2, when the large lead worm thrust sleeve 5 rotates 180 degrees, the worm wheel 2 rotates one equal part. When the worm rotates 180 degrees, it pushes the worm wheel to rotate one equal part. Within the remaining 180 degrees, the two adjacent rollers 6 of the worm wheel 2 are in a relatively static but rotating state within the fixed inner part, which is the positioning state, thereby realizing the positioning of the multi-station (multi-equal part) turntable.

[0029] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various changes or substitutions, and these should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
