[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0024] like Figure 1 As shown, an embodiment of the present application provides a turntable support mechanism, including a support frame 1, on which a turntable mechanism 2 and a support mechanism 3 are arranged, the support mechanism 3 is used to position and support the turntable mechanism 2, the support mechanism 3 includes two symmetrically arranged support components 31, the support component 31 includes a sliding component 311 and two cam components 312 symmetrically arranged on both side ends of the sliding component 311, the two cam components 312 are respectively longitudinally slidably matched with the support frame 1, the two cam components 312 are respectively located at both ends of the sliding component 311, and the cam components 312 are positioned and matched with the turntable mechanism 2.

[0025] like Figure 2 As shown, guide parts 100 are provided at both ends of the sliding component 311, and the height of one end of the guide part 100 is lower than the height of the other end of the guide part 100. The bottoms of the two guide parts 100 are respectively slidably connected to the support frame 1, and the tops of the guide parts 100 are rollingly matched with the cam components 312. The sliding component 311 is used to drive the two guide parts 100 to move horizontally to adjust the height of the two cam components 312 to move longitudinally.

[0026] Specifically, the turntable mechanism 2 is mounted on the support frame 1, and the two support assemblies 31 of the support mechanism 3 are symmetrically mounted on the support frame 1 and are respectively located below the two ends of the turntable mechanism 2. The two ends of the sliding assembly 311 are respectively fixedly connected to the two guide parts 100, a No. 1 slider is provided at the bottom of the guide part 100, a No. 1 slide rail is provided on the support frame 1, the No. 1 slider is horizontally slidably matched with the No. 1 slide rail, and the height of one end of the guide part 100 is lower than the height of the other end of the guide part 100. The fixed frame 103 of the cam assembly 312 is fixedly connected to the support frame 1, a No. 2 slide rail is vertically provided on the fixed frame 103, and a No. 2 slider is vertically provided on the connecting frame 104 of the cam assembly 312, and the No. 2 slider is longitudinally slidably matched with the No. 2 slide rail. When the sliding assembly 311 is located at the initial position, the cam 105 of the cam assembly 312 is located on one end of the guide part 100. When the turntable mechanism 2 rotates to a specified angle, the sliding assembly 311 simultaneously drives the two guide parts 100 to move horizontally, so that the cams 105 of the two cam assemblies 312 move from one end of the guide part 100 to the other end of the guide part 100. Since the height of the other end of the guide part 100 is higher than the height of one end of the guide part 100, when the cam assembly 312 moves to the other end of the guide part 100, the cam assembly 312 moves upward to position the turntable mechanism 2.

[0027] In the above structure, the sliding assembly 311 drives the guide part 100 to move horizontally, and drives the longitudinally moving cam assembly 312 to move upward to position and support the rotating turntable mechanism 2. The turntable support mechanism not only improves the rotation accuracy of the turntable mechanism 2, but also improves the support strength of the turntable mechanism 2, which can prevent the turntable 221 from deforming, and effectively improves the service life of the equipment.

[0028] like Figure 3 As shown, in one embodiment, the guide portion 100 of the turntable supporting mechanism includes a first horizontal portion 001, an inclined portion 002 and a second horizontal portion 003, the first horizontal portion 001 is connected to one end of the inclined portion 002, the second horizontal portion 003 is connected to the other end of the inclined portion 002, and the height of the first horizontal portion 001 is lower than the height of the second horizontal portion 003.

[0029] Specifically, when the sliding assembly 311 and the guide portion 100 are in the initial state, the cam 105 of the cam assembly 312 is located on the first horizontal portion 001. When the sliding assembly 311 drives the guide portion 100 to move horizontally, the cam 105 of the cam assembly 312 moves along the first horizontal portion 001 through the inclined portion 002 to the second horizontal portion 003, so that the cam assembly 312 moves upward to position and support the turntable mechanism 2. The two guide portions 100 can be driven to move and adjust the height of the longitudinal movement of the two cam assemblies 312 by a first cylinder. This configuration saves the cost of configuring a cylinder separately for the cam assembly 312.

[0030] like Figure 2 As shown, in one embodiment, the sliding assembly 311 of the turntable support mechanism includes a horizontal driving mechanism 101 and a connecting plate 102. The horizontal driving mechanism 101 is installed on the support frame 1, the driving end of the horizontal driving mechanism 101 is connected to the connecting plate 102, and the two ends of the connecting plate 102 are respectively connected to the two guide parts 100.

[0031] Specifically, the horizontal driving mechanism 101 drives the connecting plate 102 to drive the two guide parts 100 to move horizontally in one direction at the same time, so that the two cam assemblies 312 move upward or downward at the same time. This arrangement facilitates driving the guide part 100 to drive the cam assembly 312 to move up and down.

[0032] like Figure 2 As shown, in one embodiment, the horizontal driving mechanism 101 of the turntable supporting mechanism is a first cylinder. This arrangement facilitates driving the connecting plate 102 to drive the two guide parts 100 to move.

[0033] like Figure 2 As shown, in one embodiment, the cam assembly 312 of the turntable support mechanism includes a fixed frame 103, a connecting frame 104, a cam 105 and a positioning member 106, the fixed frame 103 is fixedly connected to the support frame 1, the connecting frame 104 is longitudinally slidably matched with the fixed frame 103, the cam 105 is rotationally connected to the bottom of the connecting frame 104, the positioning member 106 is fixedly connected to the top of the connecting frame 104, and the cam 105 is rollingly matched with the guide portion 100.

[0034] Specifically, the fixing frame 103 is fixedly connected to the supporting frame 1, a second slide rail is vertically arranged on the fixing frame 103, a second slider is vertically arranged on the connecting frame 104, the second slider is longitudinally slidably matched with the second slide rail, the cam 105 is rotatably connected to the bottom of the connecting frame 104 through a rotating shaft, the cam 105 is located on the guide portion 100 and rolls with the guide portion 100, one end of the positioning member 106 is fixed to the top of the connecting frame 104, and the other end of the positioning member 106 is positioned and matched with the turntable mechanism 2. When the guide portion 100 moves, the cam 105 rolls, and the cam 105 is acted on by the tilt angle force of the guide portion 100, so that the connecting frame 104 drives the cam 105 and the positioning member 106 to move upward along the connecting frame 104 to support and position the turntable mechanism 2. This arrangement facilitates the support and positioning of the turntable mechanism 2.

[0035] like Figure 1As shown, in one embodiment, the turntable mechanism 2 of the turntable support mechanism includes a rotation drive mechanism 21 and a turntable assembly 22, the rotation drive mechanism 21 is installed on the support frame 1, the driving end of the rotation drive mechanism 21 is connected to the turntable assembly 22, and the bottom end of the turntable assembly 22 is provided with a positioning head 23 for positioning and cooperating with the cam assembly 312.

[0036] Specifically, the rotary drive mechanism 21 is a rotary motor. When the rotary motor drives the turntable assembly 22 to rotate to a specified position, the positioning member 106 of the cam assembly 312 moves upward, so that the positioning head 23 of the turntable assembly 22 extends into the positioning member 106. This arrangement drives the turntable assembly 22 to rotate and cooperates with the positioning member 106 for positioning, which effectively improves the positioning effect.

[0037] like Figure 1 As shown, in one embodiment, the turntable assembly 22 of the turntable support mechanism includes a turntable 221 and two trays 222 symmetrically arranged on the turntable 221, the trays 222 are positioned and matched with the turntable 221, and two support assemblies 223 for driving the trays 222 to perform lifting movements are symmetrically arranged at the bottom of the turntable 221.

[0038] Specifically, the mold support assembly 223 drives the tray 222 to move up and down through the turntable 221. This arrangement facilitates the driving tray 222 to drive the product or mold to move.

[0039] like Figure 1 As shown, in one embodiment, the mold support assembly 223 of the turntable support mechanism includes four second cylinders 004, and the four second cylinders 004 are respectively installed on the four end corners of the bottom of the turntable 221, and the driving ends of the four second cylinders 004 pass through the turntable 221 and are connected to the tray 222.

[0040] Specifically, the four second cylinders 004 are fixedly mounted on the four end corners of the bottom of the turntable 221, and correspond to the four end corners of the tray 222. The four second cylinders 004 simultaneously drive the tray 222 to move the product or mold up and down. This arrangement facilitates the stable lifting and lowering movement of the tray 222.

[0041] like Figure 1 As shown, in one embodiment, two limit switch assemblies for preventing the turntable 221 from rotating and over-loading are provided on the support frame 1 of the turntable support mechanism. The limit switch assembly includes two limit switches 41, and the two limit switches 41 are fixed to the support frame 1 through columns 42.

[0042] Specifically, columns 42 are provided on both sides of the rotating motor, and two limit switches 41 are provided on the top of the columns 42. The two limit switches 41 monitor the rotation angle of the turntable 221. If the rotation angle of the turntable 221 exceeds the range, an alarm signal is issued to notify the staff to handle it in time. This setting is convenient for monitoring the rotation angle of the turntable 221.

[0043] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
