Description

Technical Field

[0001] This utility model belongs to the field of machine tool auxiliary equipment technology, specifically relating to an automatic loading and unloading system for machine tools. Background Technology

[0002] In the current machine tool processing field, most workpieces are transferred using robotic arms and hoppers, and then loaded and unloaded by operators using overhead cranes. This method is time-consuming, labor-intensive, and has a low degree of automation. Therefore, automatic loading and unloading systems for machine tools are used. However, when the telescopic clamping mechanism of existing machine tools grabs heavy objects or extends and retracts significantly, the center of gravity shifts, generating non-axial lateral tension on the chain of the lifting mechanism. The meshing structure of the chain and sprocket has low tolerance to lateral forces. Long-term stress will cause chain deformation and sprocket tooth wear, thereby shortening the life of the automatic loading and unloading system. Therefore, there is an urgent need for an automatic loading and unloading system for machine tools with a long actual service life. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides an automatic loading and unloading system for machine tools.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automatic loading and unloading system for machine tools, including a telescopic clamping mechanism and a base plate, and further including a rotating mechanism, a lifting mechanism, a support plate, a support block, a follow-up balancing mechanism and a controller. The lifting mechanism includes a sprocket and chain transmission assembly and a transition plate. The sprocket and chain transmission assembly and the transition plate are detachably connected. The sprocket and chain transmission assembly is installed on the upper surface of the support plate.

[0005] The rotating mechanism includes a rotary motor, a vertical cylinder, a spline connector, and a cylinder motor connector. The lower end of the vertical cylinder is detachably connected to the upper end of the base plate. The vertical cylinder is vertical in its length direction. The vertical cylinder is detachably connected to the rotary motor through the cylinder motor connector. The lower end of the spline connector is detachably connected to the upper end of the rotary motor.

[0006] The support plate includes a support rod body and an annular support part. The lower end of the support rod body and the upper end of the annular support part are fixedly connected. The lower end face of the annular support part is in contact with the support block. The lower end of the support block is in contact with the upper end face of the base plate. A spline groove is provided on the support rod body. The support rod body is slidably connected to the spline connector in the vertical direction through the spline groove.

[0007] The follow-up balancing mechanism includes a balancing cylinder and a balancing counterweight. The balancing cylinder is horizontal in the length direction. The balancing cylinder is detachably connected to the side of the adapter plate away from the telescopic clamping mechanism. The end of the balancing cylinder away from the adapter plate is detachably connected to the balancing counterweight.

[0008] The rotary motor, vertical cylinder, lifting mechanism, telescopic clamping mechanism, and balance cylinder are all connected to the controller, which is mounted on the support rod body.

[0009] Preferably, the sprocket and chain drive assembly includes a chain, a driving wheel, a driven wheel, a lifting support column, and a drive motor, wherein the lower end of the lifting support column is fixedly connected to the upper end of the support rod body;

[0010] The lifting support column is vertical in length direction. The driving wheel and the driven wheel are rotatably connected to the lifting support column. The driving wheel and the driven wheel are both in contact with the inner side of the chain. The adapter plate is detachably connected to the chain. The driving wheel is detachably connected to the drive motor. The drive motor is communicatively connected to the controller.

[0011] Preferably, the driven wheel is located directly above the driving wheel.

[0012] Preferably, the support block includes a support block body, on which a guide ring groove is formed, and the lower end face of the annular support part is in contact with the bottom surface of the guide ring groove.

[0013] Preferably, the vertical cross-section of the guide ring groove is an isosceles trapezoid.

[0014] Preferably, the support plate also includes a counterweight block, and the support plate also includes a counterweight mounting column. The lower end of the counterweight mounting column is detachably connected to the upper end of the support rod body. The counterweight mounting column is vertical in the length direction. The counterweight block has a counterweight sliding hole in the vertical direction. The counterweight block fits against the side of the counterweight mounting column through the counterweight sliding hole.

[0015] Preferably, the vertical cylinder is coaxial with the rotary motor.

[0016] Preferably, the telescopic clamping mechanism includes a horizontal telescopic cylinder, a fixed connecting plate, a clamping cylinder, and a clamping seat. The horizontal telescopic cylinder is horizontal in its length direction and is fixedly connected to the side of the adapter plate. The end of the horizontal telescopic cylinder away from the adapter plate is detachably connected to the clamping cylinder through the fixed connecting plate. The clamping cylinder is detachably connected to the clamping seat. The length direction of the horizontal telescopic cylinder is perpendicular to the length direction of the clamping cylinder.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0018] (1) The vertical cylinder is detachably connected to the rotary motor through the cylinder motor connector. When not in operation, the spline connector at the top of the rotary motor is separated from the spline groove. The whole consisting of the support plate, lifting mechanism and telescopic clamping mechanism will not continuously apply force to the rotary motor, which can improve the actual service life of the rotary motor. When in operation and the rotary motor needs to work, the spline connector at the top of the rotary motor is engaged with the spline groove, and the vertical cylinder continues to extend until the support block is separated from the ring support part. The rotation of the rotary motor is controlled by the controller to drive the whole consisting of the support plate, lifting mechanism and telescopic clamping mechanism to rotate accordingly, which greatly reduces the friction between the support block and the ring support part, making it more labor-saving and energy-saving.

[0019] (2) The side of the balance cylinder away from the telescopic clamping mechanism is detachably connected to the adapter plate. The end of the balance cylinder away from the adapter plate is detachably connected to the balance counterweight. When the telescopic clamping mechanism extends or shortens, the controller controls the balance cylinder with the balance counterweight to extend or shorten in the opposite direction. This ensures that the center of the whole consisting of the telescopic clamping mechanism, the follow-up balance mechanism and the adapter plate is on the adapter plate. This avoids the generation of a large lateral force on the chain when the material to be grabbed is heavy or the telescopic clamping mechanism extends or shortens significantly, thus improving the actual service life of the lifting mechanism.

[0020] (3) The lower end face of the annular support is in contact with the inner side of the guide ring groove, and the guide ring groove plays a guiding role;

[0021] (4) The vertical cross section of the guide ring groove is trapezoidal, which reduces the probability of friction between the side of the guide ring groove and the annular support;

[0022] (5) The vertical cylinder is coaxial with the rotary motor, making the rotary motor run more smoothly. Attached Figure Description

[0045] Example 1

[0046] The following is combined with Figures 1 to 10 Please provide a detailed description of the automatic loading and unloading system for machine tools, such as... Figure 1 and Figure 2 As shown, an automatic loading and unloading system for machine tools includes a telescopic clamping mechanism 3 and a base plate 5, as well as a rotating mechanism 1, a lifting mechanism 2, a support plate 6, a support block 7, a follow-up balancing mechanism 8, and a controller.

[0050] The rotary motor 11, vertical cylinder 12, lifting mechanism 2, telescopic clamping mechanism 3 and balance cylinder 81 are all connected to the controller, which is installed on the support rod body 61.

[0051] like Figure 3 , Figure 4 and Figure 5 As shown, the sprocket and chain drive assembly includes a chain 21, a drive wheel 22, a driven wheel 23, a lifting support column 24, and a drive motor. The lower end of the lifting support column 24 is fixedly connected to the upper end of the support rod body 61.

[0052] The lifting support column 24 is vertical in the length direction. The driving wheel 22 and the driven wheel 23 are rotatably connected to the lifting support column 24. The driving wheel 22 and the driven wheel 23 are both in contact with the inner side of the chain 21. The adapter plate 25 is detachably connected to the chain 21. The driving wheel 22 is detachably connected to the drive motor. The drive motor is communicatively connected to the controller.

[0053] Driven wheel 23 is located directly above driving wheel 22.

[0054] like Figure 10 As shown, the support block 7 includes a support block body 71, and a guide ring groove 72 is provided on the support block body 71. The lower end face of the annular support part 62 is in contact with the bottom surface of the guide ring groove 72.

[0055] like Figure 10 As shown, the vertical cross-section of the guide ring groove 72 is an isosceles trapezoid.

[0056] like Figure 3 As shown, it also includes a counterweight 4, and the support plate 6 also includes a counterweight mounting column 63.

[0059] Working principle of automatic loading and unloading system for machine tools:

[0060] When not in operation, the vertical cylinder 12 is in a shortened state, the spline connector 13 at the upper end of the rotary motor 11 is separated from the spline groove, and the whole consisting of the support plate 6, the lifting mechanism 2 and the telescopic clamping mechanism 3 will not continuously apply force to the rotary motor 11, and the time when the rotary motor 11 is subjected to pressure is greatly reduced.

[0061] When the rotating motor 11 is in operation and needs to work, the vertical cylinder 12 extends under the action of the controller, so that the spline connector 13 at the upper end of the rotating motor 11 engages with the spline groove. The vertical cylinder 12 continues to extend until the support block 7 separates vertically from the annular support part 62. The rotation of the rotating motor 11 is controlled by the controller to drive the support plate 6, the lifting mechanism 2 and the telescopic clamping mechanism 3 to rotate accordingly, which greatly reduces the friction between the support block 7 and the annular support part 62.

[0062] As the technical solution of this utility model, the hardware settings provided are only for facilitating the implementation of braking control based on the hardware facilities. How to implement braking control and the specific braking control method are not the technical problems to be solved or the objects to be protected by this utility model.

[0063] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
