Description

Technical Field

[0001] The utility model relates to the field of mechanical processing, in particular to a turntable device. Background Art

[0002] A turntable (also called a slewing table or rotating table) is a mechanical structure used to realize the horizontal rotational movement of an object or equipment. It usually consists of a base and a rotating platform on it. The base is fixed to the ground or other supporting structure, and the rotating platform can rotate relative to the base.

[0003] Turntables are widely used in industrial production, assembly lines, mechanical processing, laboratory equipment and other fields to facilitate the positioning and rotation of objects or equipment. For example, Chinese patent No. CN118321932A discloses a dual-drive turntable with an exchange structure. The turntable provides power and control by introducing a dual-drive structure consisting of a first drive unit and a second drive unit. The structure is simple, the transmission chain is short, and there are few failure points.

[0004] However, when the turntable structure is in use, if other supporting operations need to be performed, they often need to be performed separately and are difficult to be performed automatically during the rotation of the turntable, resulting in additional workload. Utility Model Content

[0005] The purpose of the utility model is to provide a turntable device to solve the problem that when the turntable structure in the background technology is in use, if other supporting operations need to be performed, they often need to be performed separately and are difficult to be performed automatically during the rotation of the turntable, resulting in additional workload.

[0006] The utility model provides a turntable device, comprising a base and a turntable, wherein the turntable is rotatably arranged above the base;

[0007] A collision block is arranged on one side of the turntable close to the base, and a spring switch is arranged on one side of the base close to the turntable, and the spring switch is located on the rotation path of the collision block;

[0008] The collision block can cooperate with the spring switch to realize the on and off of the spring switch.

[0009] The turntable device described in the present application is arranged above the base for rotation of the turntable, a collision block is arranged on the side of the turntable close to the base, a spring switch is arranged on the side of the base close to the turntable, and the spring switch is located on the rotation path of the collision block. When the turntable rotates, the collision block can cooperate with the spring switch, so that the collision block can trigger the spring switch, so that the spring switch can realize on-off conversion when triggered by the collision block, forming an on-off signal, and then the circuit connected to the spring switch can start the supporting operations that need to be performed after receiving the on-off signal, so as to achieve the effect of automatically performing other supporting operations during the rotation of the turntable, thereby simplifying the operation process and reducing the workload.

[0010] Preferably, the top of the spring switch has an opening and closing contact, and the impact block can press down the opening and closing contact.

[0011] By having an opening and closing contact on the top of the spring switch, when the turntable rotates, when the impact block contacts the opening and closing contact, the impact block presses down the opening and closing contact to connect the spring switch. After the impact block separates from the opening and closing contact, the spring switch is disconnected, so that the spring switch outputs an on-off signal.

[0012] Preferably, an arc-shaped portion is provided at one end of the collision block close to the spring switch.

[0013] By arranging an arc portion at one end of the impact block close to the switch, during the rotation of the turntable, the arc portion first contacts the opening and closing contacts, and then presses down the opening and closing contacts, thereby preventing the impact block from directly colliding with the opening and closing contacts and causing damage to the opening and closing contacts.

[0014] Preferably, the spring switches are arranged at intervals along the rotation path of the impact block, so that a plurality of spring switches can be arranged on the rotation path of the impact block, thereby generating a plurality of on-off signals and facilitating the control of a plurality of matching operations.

[0015] Preferably, the spring switch comprises a housing, a first spring and a second spring are installed in the housing, the first spring and the second spring are arranged opposite to each other, and the second spring is partially located below the first spring;

[0016] The first elastic piece is connected to the opening and closing contact, and the opening and closing contact passes through the housing.

[0017] Since the opening and closing contacts pass through the shell, the opening and closing contacts are located on the outside of the shell, which facilitates the contact between the impact block and the opening and closing contacts. When the impact block presses down the opening and closing contacts, the opening and closing contacts drive the first spring sheet to move downward, so that the first spring sheet contacts the second spring sheet, thereby realizing the connection of the spring sheet switch. After the impact block is separated from the opening and closing contacts, the first spring sheet rebounds, and the first spring sheet is separated from the second spring sheet, thereby realizing the disconnection of the spring sheet switch.

[0018] Preferably, it further comprises a hollow shaft, which is rotatably arranged in the base, one end of which is fixedly connected to the turntable, and the other end of which is provided with a worm gear;

[0019] It also includes a motor, which drives a worm, and the worm cooperates with the worm wheel.

[0020] Preferably, a first gear is installed on the rotating shaft of the motor, a second gear is installed on one end of the worm gear close to the motor, and the first gear is meshed with the second gear;

[0021] A reduction gear pair is formed between the first gear and the second gear.

[0022] Preferably, the diameter of the first gear is greater than the diameter of the second gear.

[0023] Preferably, a first circular hole is formed on the base, and a side wall of the first circular hole is provided with an annular step portion;

[0050] Example 1

[0051] like Figure 1-Figure 3 The turntable device described in this embodiment includes a base 1, and a turntable 2 is rotatably arranged on the base 1;

[0052] A collision block 8 is provided on one side of the turntable 2 close to the base 1, and a spring switch 9 is provided on one side of the base 1 close to the turntable 2. The spring switch 9 is located on the rotation path of the collision block 8;

[0053] The impact block 8 can cooperate with the spring switch 9 to realize the on and off of the spring switch 9.

[0054] When the turntable 2 rotates, the turntable 2 drives the impact block 8 to move, so that the impact block 8 performs a circular motion. During the circular motion of the impact block 8, the impact block 8 can cooperate with the spring switch 9, so that the impact block 8 can trigger the spring switch 9, so that the spring switch 9 can realize the on-off conversion when triggered by the impact block 8, forming an on-off signal, and then the circuit connected to the spring switch 9 can start the supporting operations that need to be performed after receiving the on-off signal, so as to achieve the effect of automatically performing other supporting operations during the rotation of the turntable 2, thereby simplifying the operation process and reducing the workload.

[0055] The turntable device described in this embodiment can input an on-off signal to the circuit system or control software through the cooperation of the impact block 8 and the spring switch 9, so that the circuit system or control software can automatically perform other supporting operations during the rotation of the turntable 2, such as controlling the turntable 2 to stop, performing other operations or linking with other mechanisms.

[0056] In one or more embodiments, Figure 3 , Fig.10 As shown, the top of the spring switch 9 has an opening and closing contact 91, and the impact block 8 can press down the opening and closing contact 91.

[0057] By providing an opening and closing contact 91 at the top of the spring switch 9, during the rotation of the turntable 2, when the impact block 8 contacts the opening and closing contact 91, the impact block 8 presses down the opening and closing contact 91 to connect the spring switch 9. After the impact block 8 separates from the opening and closing contact 91, the spring switch 9 is disconnected, so that the spring switch 9 outputs an on-off signal.

[0058] In an optional embodiment, if Figure 8 , Fig. 9 As shown, an arc portion 81 is provided at one end of the impact block 8 close to the spring switch 9 .

[0059] During the rotation of the turntable 2, the arc portion 81 of the impact block 8 first contacts the opening and closing contact 91, and then the arc portion 81 presses down the opening and closing contact 91, thereby preventing the impact block 8 from directly colliding with the opening and closing contact 91 and causing damage to the opening and closing contact 91. The arc surface of the arc portion 81 protrudes toward the side of the spring switch 9. When the impact block 8 cooperates with the spring switch 9, the impact block 8 performs a circular motion driven by the turntable 2. After the arc portion 81 contacts the opening and closing contact 91, the middle convex point of the arc portion 81 will squeeze the opening and closing contact 91 downward to realize the connection of the spring switch 9. After the arc portion 81 separates from the opening and closing contact 91, the opening and closing contact 91 rebounds to disconnect the spring switch 9, thereby causing the spring switch 9 to output an on-off signal.

[0060] In an optional embodiment, if Figure 8 , Fig. 9 As shown, the collision block 8 is provided with a first mounting hole 82, and the collision block 8 is mounted through the first mounting hole 82. Figure 3 As shown, the impact block 8 is fixedly mounted on the turntable 2 by screws passing through the first mounting hole 82 .

[0061] In an optional embodiment, if Fig.10 , Fig.11 As shown, the spring switch 9 includes a housing 93, in which a first spring 94 and a second spring 95 are installed. The first spring 94 and the second spring 95 are arranged opposite to each other, and a portion of the second spring 95 is located below the first spring 94;

[0062] The first elastic piece 94 is connected to the opening and closing contact 91 , and the opening and closing contact 91 passes through the housing 93 .

[0063] Since the opening and closing contact 91 passes through the housing 93, the opening and closing contact 91 is located outside the housing 93, which facilitates the contact between the collision block 8 and the opening and closing contact 91. When the collision block 8 presses the opening and closing contact 91, the opening and closing contact 91 drives the first spring 94 to move downward, so that the first spring 94 contacts the second spring 95, and the spring switch 9 is turned on. After the collision block 8 is separated from the opening and closing contact 91, the first spring 94 rebounds, and the first spring 94 is separated from the second spring 95, and the spring switch 9 is turned off. Fig.11As shown, there is an opening at the top of the housing 93, and the opening and closing contacts 91 pass through the opening and are located outside the housing 93.

[0064] like Fig.11 As shown, the first spring piece 94 and the second spring piece 95 are both screwed into the housing 93, the first spring piece 94 connects one circuit, and the second spring piece 95 connects another circuit. When the first spring piece 94 and the second spring piece 95 are in contact, the two circuits are connected to form a passage, and when the first spring piece 94 and the second spring piece 95 are separated, the two circuits are disconnected to form a short circuit.

[0065] The housing 93 is also provided with a second mounting hole 92, through which the spring switch 9 is mounted. Figure 1 As shown, the spring switch 9 is fixedly mounted on the base 1 by screws passing through the second mounting hole 92 .

[0066] In an optional embodiment, the spring switches 9 are arranged at intervals along the rotation path of the impact block 8. It is convenient to arrange multiple spring switches 9 on the rotation path of the impact block 8, thereby generating multiple on-off signals, which is convenient for controlling multiple matching operations.

[0067] In one or more embodiments, Figure 6 , Figure 7 As shown, it also includes a hollow shaft 4, which is rotatably arranged in the base 1, one end of the hollow shaft 4 is fixedly connected to the turntable 2, and the other end of the hollow shaft 4 is installed with a worm gear 5;

[0068] The device also includes a motor 3 , which drives a worm 6 , and the worm 6 cooperates with the worm wheel 5 .

[0069] The motor 3 drives the worm 6. Since the worm 6 cooperates with the worm wheel 5, the worm wheel 5 is driven to rotate by the worm 6. When the worm wheel 5 rotates, the hollow shaft 4 is rotated with it. When the hollow shaft 4 rotates, the turntable 2 is rotated with it.

[0070] In an optional embodiment, if Fig.12 As shown, a first circular hole 11 is formed on the base 1, and an annular step portion 13 is formed on the side wall of the first circular hole 11;

[0071] like Figure 4 , Figure 5 , Fig.13 As shown, the end of the turntable 2 close to the hollow shaft 4 has a truncated cone 21, and the end of the hollow shaft 4 close to the turntable 2 has a shaft collar 41, and an annular groove is formed between the truncated cone 21 and the shaft collar 41;

[0072] The bearing 7 is also included. The bearing 7 is mounted on the annular groove, and a portion of the bearing 7 is placed on the annular step portion 13 .

[0073] Through the above structure, the turntable 2 and the hollow shaft 4 can be rotatably arranged on the base 1 through the bearing 7, so that the motor 3 drives the worm 6 to drive the turntable 2 to rotate.

[0074] Among them, Fig.13 As shown, the collar 41 refers to an annular plate disposed on the hollow shaft 4 and coaxial with the hollow shaft 4. In this embodiment, the collar 41 is used to separate the bearing 7 and the worm gear 5 so that the bearing 7 and the worm gear 5 do not affect each other.

[0075] In an optional embodiment, if Figure 4 , Fig.13 As shown, the end of the hollow shaft 4 away from the turntable 2 has a shaft shoulder 42 , and the shaft shoulder 42 is located below the shaft collar 41 . The shaft shoulder 42 is used to mount the worm gear 5 .

[0076] In an optional embodiment, an annular cover 30 is further included. The annular cover 30 is used to press the bearing 7 , and the annular cover 30 is fixed on the base 1 .

[0077] The annular cover 30 is used to compress the bearing 7, thereby fixing the bearing 7 and preventing the bearing 7 from coming off the base 1 during the rotation process.

[0078] Example 2

[0079] like Figure 7 As shown, based on Example 1, a turntable device described in the present application, a first gear 10 is installed on the rotating shaft of the motor 3, a second gear 20 is installed at one end of the worm 6 close to the motor 3, and the first gear 10 is meshed with the second gear 20;

[0080] A reduction gear pair is formed between the first gear 10 and the second gear 20 .

[0081] By setting a reduction gear pair between the motor 3 and the worm 6, the rotation speed of the worm 6 is reduced, the torque of the worm 6 is increased, and the rotation force of the turntable 2 is greater, and it can bear heavier objects. Furthermore, when the temperature is low, the lubricating grease between the components of the device becomes viscous, which will increase the resistance between the components. At this time, since the reduction gear pair is set between the motor 3 and the worm 6, the torque of the worm 6 is increased, which can effectively drive the worm wheel 5 to rotate, so that the turntable device of the present application can be used normally even at low temperatures;

[0082] At the same time, since the reduction gear pair reduces the rotation speed of the worm 6, the wear between the worm 6 and the worm wheel 5 is reduced, and the service life of the worm 6 and the worm wheel 5 is extended;

[0083] Furthermore, the gear module of the worm wheel 5 is increased to increase the thickness of the teeth, reduce the rotation speed of the worm wheel 5, and make the worm wheel 5 more wear-resistant.

[0084] In an optional embodiment, the diameter of the first gear 10 is greater than the diameter of the second gear 20, wherein the first gear 10 is mounted on the rotating shaft of the motor 3 and is an input gear, and the second gear 20 is mounted on the worm 6 and is an output gear.

[0085] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
