Description

Technical Field

[0001] This utility model relates to the field of electric turntable technology, specifically an electric horizontal turntable. Background Technology

[0002] The horizontal turntable of a single-color injection molding machine usually refers to the turntable structure on the injection molding machine used for mold switching and molding operations. The horizontal turntable of a single-color injection molding machine is mainly used to achieve rapid mold switching and positioning. The horizontal turntable can achieve high-precision positioning through mechanical, electrical or hydraulic systems. The structural design of the horizontal turntable makes it more stable when carrying the mold, reducing deformation and wear caused by gravity.

[0003] Horizontal turntables can support heavy molds. When the horizontal turntable rotates while supporting the mold, its inertia increases. Some existing electric horizontal turntables are driven by a motor and gear transmission components. However, some horizontal turntables do not effectively limit the rotation range, which affects the accuracy of the turntable rotation and makes the controllability of the supported mold poor, making them inconvenient to use.

[0025] 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.

[0026] Please see Figure 1-4 This utility model provides a technical solution: an electric horizontal turntable 141, comprising,

[0027] There are two fixing plates 10, and multiple Green Columns 11 are fixedly connected between the two fixing plates 10.

[0028] The limit frame 12 is provided with multiple green columns 11 that pass through adjacent limit frames 12 and are slidably connected to them;

[0029] Shaft 14 is rotatably connected to the outside of the limiting frame 12, and a turntable 141 is fixedly sleeved on the outer wall of shaft 14.

[0030] The control plate 15 is rotatably connected to the outer wall of the limiting frame 12. The control plate 15 is used to drive and position the turntable 141.

[0031] The drive module 17 is located outside the limit frame 12 and is used to control the turntable 141.

[0032] In practice, the servo motor 171 is started to drive the support arm 172 to rotate, which in turn moves the guide block 173. The guide block 173 is inserted into the control groove 152 and causes the control plate 15 to rotate. The support arm 172 rotates one revolution, causing the circular plate 162 and the gear ring 163 to rotate 90 degrees. Thus, the turntable 141 rotates 90 degrees through the meshing of the gear ring 163 and the gear 142. During the process, multiple positioning plates 175 will successively limit the limit groove 151, thereby limiting the angle of each rotation of the limit groove 151 to 90 degrees.

[0033] The electric push rod 13 can drive the limit frame 12 to move, and can separately control the two limit frames 12 and the turntable 141, so that the two turntables 141 can move laterally at a uniform speed and in a stable manner to adjust their positions.

[0034] See Figure 4 Multiple limiting sleeves 121 are fixedly connected to the two outer side walls of the limiting frame 12. Green column 11 penetrates the adjacent limiting sleeve 121. Multiple ball bearings 122 are equidistantly rotatably connected to the inner wall of the limiting sleeve 121.

[0035] In practice, multiple ball bearings 122 and two limiting sleeves 121 are used to stably slide and limit the limiting frame 12 laterally. The ball bearings 122 can avoid direct contact with the limiting sleeves 121, thereby reducing sliding friction. When the electric push rod 13 is activated to adjust the limiting frame 12 laterally, it is smoother and the position of the turntable 141 can be adjusted more easily.

[0036] See Figure 1 Each of the two limit frames 12 is provided with an electric push rod 13 on one side. The Green column 11 passes through the adjacent electric push rod 13 and is fixedly connected to it. The output end of the electric push rod 13 is fixedly connected to the outer wall of the adjacent limit frame 12.

[0037] In practice, the electric push rod 13 is fixed on the two Green columns 11. Activating the electric push rod 13 can drive the limit frame 12 to move, and can separately control the two limit frames 12 and the turntable 141, so that the two turntables 141 can move horizontally at a uniform speed to adjust their positions.

[0038] See Figure 2-3 A gear 142 is fixedly sleeved on the outer wall of shaft 14. A mounting plate 16 is fixedly connected to the outer wall of the limiting frame 12. Shaft 161 is rotatably connected to the bottom of the mounting plate 16. Shaft 161 passes through the control plate 15 and is fixedly connected to it. A circular plate 162 is fixedly sleeved on the outer wall of shaft 161. A gear ring 163 is fixedly sleeved on the outer wall of the circular plate 162. The gear ring 163 meshes with the gear 142.

[0039] Multiple limiting grooves 151 and regulating grooves 152 are equidistantly provided on the outer wall of the regulating plate 15, and the limiting grooves 151 and regulating grooves 152 are distributed alternately.

[0040] The drive module 17 includes a servo motor 171 fixedly connected to one side of the mounting plate 16. A support arm 172 is fixedly sleeved on the output end of the servo motor 171, and a guide block 173 is fixedly connected to one end of the support arm 172.

[0041] A clamping plate 174 is fixedly sleeved on the output end of the servo motor 171, and multiple positioning plates 175 are fixedly sleeved at equal intervals on the outer wall of the clamping plate 174.

[0042] In specific implementation, shaft 14 limits the rotation of turntable 141 and gear 142, and shaft 161 limits the rotation of control plate 15, circular plate 162 and gear ring 163. Gear 142 and gear ring 163 have the same number of teeth and mesh with each other. The servo motor 171 is started to drive the support arm 172 to rotate, which drives the guide block 173 to move. The guide block 173 is inserted into the control groove 152 and moves the control plate 15 to rotate. The support arm 172 rotates one revolution, causing the circular plate 162 and gear ring 163 to rotate 90 degrees. Thus, the meshing of gear ring 163 and gear 142 causes turntable 141 to rotate 90 degrees. During the process, multiple positioning plates 175 will successively limit the limit groove 151, thereby limiting the angle of each rotation of the limit groove 151 to 90 degrees.

[0043] Working principle: The servo motor 171 is started to drive the support arm 172 to rotate, which drives the guide block 173 to move. The guide block 173 is inserted into the control groove 152 and moves the control plate 15 to rotate. The support arm 172 rotates one revolution, causing the circular plate 162 and the gear ring 163 to rotate 90 degrees. Thus, through the meshing of the gear ring 163 and the gear 142, the turntable 141 rotates 90 degrees. During the process, multiple positioning plates 175 will successively limit the limit groove 151, thereby limiting the angle of each rotation of the limit groove 151 to 90 degrees.

[0044] The electric push rod 13 can drive the limit frame 12 to move, and can separately control the two limit frames 12 and the turntable 141, so that the two turntables 141 can move laterally at a uniform speed and in a stable manner to adjust their positions.
