Description

Technical Field

[0001] The utility model relates to the technical field of tailstock locking, in particular to a tailstock locking device for a turning machining center. Background Art

[0002] With the continuous development of society and the continuous progress of technology, the technology related to tailstock locking is also constantly improving. At present, a turning machining center is often used to machine disc-shaped or shaft-shaped parts. During this process, the center on the tailstock needs to extend to press against the workpiece, or a clamping mechanism arranged on the tailstock spindle is used to clamp the workpiece to achieve the positioning of the workpiece.

[0003] At present, the tailstock is generally slidably mounted on the body of the turning machining center through a guide rail, and the tailstock can be moved according to the processing requirements. When the position of the tailstock is determined, it is necessary to manually lock the tailstock, and the operation is relatively cumbersome and inconvenient, which is not conducive to the quick locking of the tailstock. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the following disadvantages in the prior art. At present, the tailstock is generally slidably mounted on the body of the turning machining center through a guide rail, and the tailstock can be moved according to the processing requirements. When the position of the tailstock is determined, it is necessary to manually lock the tailstock, and the operation is relatively cumbersome and inconvenient, which is not conducive to the quick locking of the tailstock. Therefore, a tailstock locking device for a turning machining center is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A tailstock locking device for a turning machining center includes a body guide rail and a tailstock bottom plate. The tailstock bottom plate is slidably arranged on the body guide rail. An electric push rod is fixedly installed on the tailstock bottom plate. The driving end of the electric push rod is fixedly connected with a bent rod, and two cross plates are fixedly connected to the bent rod.

[0007] An installation cavity is formed on the tailstock bottom plate. Two pressing plates are slidably connected in the installation cavity. A plurality of friction protrusions are fixedly connected to one side surface of each pressing plate. Two rotating components are arranged in the installation cavity. Each rotating component includes a gravity rod rotatably installed on one inner wall of the installation cavity. The cross section of the gravity rod is L-shaped, and a rotating piece is fixedly connected to each gravity rod.

[0008] Preferably, each rotating piece is made of plastic material, and the two rotating pieces are arranged in a V-shaped pattern.

[0009] Preferably, the cross section of each pressing plate is T-shaped, and an arc-shaped rubber block is fixedly connected to one side surface of the pressing plate.

[0010] Preferably, both inner walls of the installation cavity are fixedly connected with springs, and the two springs are respectively fixedly connected with the two pressing plates.

[0011] Preferably, the upper end of the bending rod is fixedly connected with a slider, and a pulley is rotatably connected to the slider.

[0012] Preferably, the cross-section of the slider is in an I-shaped arrangement, and sliding grooves for the up-and-down sliding of the slider are provided on both inner walls of the installation cavity.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] During the movement of each pressing plate, the rough friction protrusions on each surface will be in close contact with the surface of the machine body guide rail, and after the movement of each arc-shaped rubber block, it will be in close contact with the lower surface of the machine body guide rail. The frictional force between the friction protrusions and the arc-shaped rubber block and the machine body guide rail is large enough to effectively prevent the relative sliding between the tailstock base plate and the machine body guide rail, realizing the rapid locking of the tailstock base plate, eliminating the need for manual locking of the tailstock, and making the operation more convenient and fast.

Detailed Embodiment

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and clarity, and are not used to limit the scope of implementation of the present utility model. The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the scope of implementation of the present utility model.

[0021] Reference Figures 1 - 3 , a tailstock locking device for a turning machining center, comprising a machine body guide rail 1 and a tailstock bottom plate 2. The tailstock bottom plate 2 is slidably arranged on the machine body guide rail 1. An electric push rod 3 is fixedly installed on the tailstock bottom plate 2. The driving end of the electric push rod 3 is fixedly connected with a bent rod 4. Two cross plates 9 are fixedly connected to the bent rod 4. An installation cavity 14 is formed on the tailstock bottom plate 2. Two pressing plates 8 are slidably connected in the installation cavity 14. A plurality of friction protrusions 6 are fixedly connected to one side surface of each pressing plate 8. Two rotating components are arranged in the installation cavity 14. Each rotating component includes a gravity rod 12 rotatably installed on one inner wall of the installation cavity 14. The cross section of the gravity rod 12 is L-shaped. A rotating piece 11 is fixedly connected to each gravity rod 12.

[0022] Each rotating piece 11 is made of plastic material. The two rotating pieces 11 are arranged in a V-shaped pattern. The gravity rod 12 has a relatively large mass, and the plastic rotating piece 11 has a relatively small mass. In the initial state, the L-shaped gravity rod 12 is vertically downward, the two rotating pieces 11 are arranged in a V-shaped pattern, and the surface of the gravity rod 12 does not contact the surface of the pressing plate 8. The cross section of each pressing plate 8 is T-shaped. An arc-shaped rubber block 15 is fixedly connected to one side surface of the pressing plate 8. During the movement of each pressing plate 8, the rough friction protrusions 6 on each surface will be in close contact with the surface of the machine body guide rail 1. After the movement of each arc-shaped rubber block 15, it will be in close contact with the lower surface of the machine body guide rail 1. The friction between the friction protrusions 6 and the arc-shaped rubber block 15 and the machine body guide rail 1 is relatively large, which can effectively prevent the relative sliding between the tailstock bottom plate 2 and the machine body guide rail 1.

[0023] Both inner walls of the installation cavity 14 are fixedly connected with springs 13. The two springs 13 are respectively fixedly connected to the two pressing plates 8. During the rotation of each L-shaped gravity rod 12, one end of it will move against the surface of the corresponding pressing plate 8, causing the distance between the two pressing plates 8 to increase, and the spring 13 deforms. The upper end of the bent rod 4 is fixedly connected with a slider 7. A pulley 5 is rotatably connected to the slider 7. The cross section of the slider 7 is I-shaped. Both inner walls of the installation cavity 14 are provided with sliding grooves 10 for the up and down sliding of the slider 7. The sliding grooves 10 can limit the movement track of the slider 7. The cross section of the part of the slider 7 in contact with the pulley 5 is circular. When the tailstock bottom plate 2 moves along the machine body guide rail 1, the pulley 5 will roll along the surface of the machine body guide rail 1 to facilitate the rapid movement of the tailstock bottom plate 2.

[0024] In the present utility model, during use, the tailstock base plate 2 can move along the machine body guide rail 1, and the pulley 5 simultaneously rolls along the surface of the machine body guide rail 1. When the tailstock base plate 2 moves to a suitable position, the electric push rod 3 drives the bending rod 4 to move downward, and the slider 7 also moves downward, thereby driving the pulley 5 to separate from the surface of the machine body guide rail 1. During the process of the two cross plates 9 moving downward together with the bending rod 4 inside the installation cavity 14, they will respectively abut against the corresponding rotating pieces 11 and move, causing the two rotating pieces 11 to change from an eight-shaped arrangement to an inverted eight-shaped arrangement. Under the transmission action of the two rotating pieces 11, the two gravity rods 12 rotate simultaneously. After one end of each L-shaped gravity rod 12 rotates, it will abut against the surface of the corresponding pressing plate 8 and move, causing the distance between the two pressing plates 8 to increase, and the spring 13 deforms. During the movement of each pressing plate 8, the rough friction protrusions 6 on each surface will be in close contact with the surface of the machine body guide rail 1, and each arc-shaped rubber block 15 will be in close contact with the lower surface of the machine body guide rail 1 after moving. The friction between the friction protrusions 6 and the arc-shaped rubber blocks 15 and the machine body guide rail 1 is relatively large, which can effectively prevent the relative sliding between the tailstock base plate 2 and the machine body guide rail 1, realizing the rapid locking of the tailstock base plate 2, and there is no need to manually lock the tailstock, and the operation is relatively convenient and fast.

[0025] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "connection", "fixation", etc. shall be understood in a broad sense.

[0026] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
