[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.
[0025] Embodiment one
[0026] In the prior art, an inclined lathe machine usually is equipped with a vertical clamp to fix a workpiece. Therefore, when installing the workpiece, the operator must first hold the workpiece horizontally, and then places the area to be fixed into the chuck for fixation. Before the fixation process is completely finished, the operator needs to continuously hold the workpiece to ensure that the fixation angle of the workpiece is correct. This process requires a high physical strength of the operator, which may adversely affect the installation accuracy of the workpiece and the production efficiency.
[0027] Therefore, in order to solve the above problems and realize the functions of reducing the physical strength consumption of the installer and improving the work efficiency, the utility model discloses a lathe clamping base for inclined lathe machining, referring to Figure 1 and Figure 2 , comprising a base 1 and a chuck 3, specifically, the base (1) is internally provided with a cavity, the chuck (3) is fixedly arranged in the cavity, wherein the chuck (3) is provided with an insertion hole (6) at the center of the middle axis on both sides, the two insertion holes (6) are communicated to form a clamping pipeline (5), the outer wall of the base (1) is provided with a guide hole (2), and the guide hole (2) is located at the position corresponding to the chuck (3), and the center of the middle axis of the guide hole (2) and the center of the insertion hole (6) are located on the same straight line.
[0028] In the embodiment, when the workpiece is installed, the operator can put the end to be fixed of the workpiece along the guide hole 2, which provides initial guidance for the workpiece and cooperates with the base 1 to give the workpiece certain support, so that the operator does not need to hold the workpiece all the time, reducing physical exertion. For example, for some long columnar workpieces, the guide hole 2 can prevent the workpiece from tilting or deviating excessively before being put into the chuck 3, improving the convenience and accuracy of installation.
[0029] At the same time, the end of the workpiece entering through the guide hole 2 passes through the insertion hole 6 into the clamping pipe 5, at this time, the user can continuously push the workpiece towards the clamping pipe 5, so that part of the end of the workpiece can be immersed in the clamping pipe 5, thereby improving the clamping depth of the workpiece and further improving the fixing stability of the workpiece. Due to the cooperation of the clamping pipe 5 and the guide hole 2, the workpiece is not easy to slide or displace during installation, which helps to improve the stability of the workpiece during processing.
[0030] In addition, the top of the base 1 can be provided in an open structure to facilitate the installer to observe the landing point of the workpiece on the chuck 3.
[0031] Further, after the end to be fixed of the workpiece is inserted into the clamping pipe 5, at least two sliding grooves 7 are provided on the chuck 3, and the number of clamping jaws 4 is equal to that of the sliding grooves 7. The sliding grooves 7 extend towards the insertion hole 6, and the clamping jaws 4 are slidably arranged in the sliding grooves 7. The user can adjust the position of the clamping jaws 4 in the sliding grooves 7 to clamp the workpiece.
[0032] In a specific embodiment, a lead screw 9 is arranged in the sliding groove 7 and extends along the length direction of the sliding groove 7. The lead screw 9 is arranged in the clamping jaw 4, and a driving member 8 is arranged in the sliding groove 7 for rotating the lead screw 9. Through this arrangement, when the workpiece needs to be clamped, the operator starts the driving member 8, and the driving member 8 drives the lead screw 9 to rotate. Since the lead screw 9 and the clamping jaw 4 are arranged in each other, the rotary motion of the lead screw 9 will be converted into the linear motion of the clamping jaw 4. The threaded structure of the lead screw 9 will make the clamping jaw 4 slide along the sliding groove 7 towards the insertion hole 6 until the workpiece is clamped.
[0033] It should be noted that the driving member 8 can be an electric motor, and the driving member 8 is connected to the upper computer for unified control.
[0034] As a preferred technical solution, four sliding grooves 7 are arranged on the chuck 3 in an X-shaped manner, so that the four clamping jaws 4 can apply clamping force to the workpiece from different directions, which can effectively prevent the workpiece from deviating or deforming due to uneven force.
[0035] Optionally, the side of the clamping jaw 4 facing the insertion hole 6 is provided with a plurality of columnar protrusions, which can increase the friction between the clamping jaw 4 and the workpiece, thereby preventing the workpiece from loosening or rotating during machining due to cutting force, vibration and other factors. For example, when machining some smooth metal columnar workpieces, the columnar protrusions can significantly enhance the gripping force between the clamping jaw 4 and the workpiece, ensuring the stability and safety of the machining process.
[0036] Embodiment two
[0037] On the basis of embodiment one, in order to make the chuck 3 suitable for columnar workpieces of different lengths, referring to Figure 5 The utility model also includes a stop disc 12 for limiting the columnar workpiece, specifically, the inside of the clamping pipeline 5 is provided with the stop disc 12, and the center of the stop disc 12 is distributed with the center of the insertion hole 6;
[0038] In this embodiment, the height of the stop disc 12 in the clamping pipeline 5 is adjustable, and the clamping pipeline 5 can be adapted to columnar workpieces of different lengths by adjusting the height of the stop disc 12, specifically, it further includes a telescopic assembly and a clamping groove, wherein the clamping groove is a through groove opened on the clamping pipeline 5 and extends along the length direction of the clamping pipeline 5, the telescopic assembly includes a telescopic rod 10 and a traction column 11, the telescopic rod 10 is arranged in the inside of the chuck 3, two telescopic rods 10 are oppositely arranged on both sides of the clamping pipeline 5, and the traction column 11 is connected between the stop disc 12 and the telescopic rod 10 through the clamping groove, through this arrangement, the installer can drive the traction column 11 to move in the length direction of the clamping pipeline 5 by starting the telescopic rod 10, so as to adjust the height of the stop disc 12 in the clamping pipeline 5.
[0039] For example, when the length of the workpiece is short, in order to prevent the whole workpiece from sinking into the clamping pipeline 5, the user can move the stop disc 12 towards the insertion hole 6 to shorten the insertable depth of the clamping pipeline 5, on the contrary, if the workpiece is long, the user can move the stop disc 12 away from the insertion hole 6 to increase the insertable depth of the clamping pipeline 5. In this way, the position adjustment of the stop disc 12 can ensure the proper fixation of the workpiece and avoid displacement or tilting of the workpiece during machining.
[0040] In addition, through the setting of the clamping groove, the lifting path of the stop disc 12 can be limited to ensure that the movement of the stop disc 12 in the clamping pipeline 5 will not exceed the predetermined range, and also helps to avoid the stop disc 12 from shaking.
[0041] In this embodiment, the telescopic rod 10 is connected with a telescopic air cylinder, and the telescopic rod 10 can drive the traction column 11 to lift or lower through the telescopic air cylinder.
[0042] In summary, in combination with Embodiment One and Embodiment Two, the working steps of the lathe clamping base for inclined machining are as follows:
[0043] Firstly, the operator puts the end of the workpiece to be machined along the guide hole 2, and uses the initial guiding effect of the guide hole 2 in cooperation with the support of the base 1 to reduce the physical burden of the operator.
[0044] Then, the end of the workpiece passes through the insertion hole 6 into the clamping pipeline 5, and the operator can continue to push the workpiece so that part of the end of the workpiece is immersed in the clamping pipeline 5, thereby increasing the clamping depth and improving the fixing stability of the workpiece.
[0045] Then, the operator adjusts the position of the clamping jaw 4 in the sliding groove 7 and uses the driving member 8 (such as a motor) to clamp the workpiece. The rotary motion of the lead screw 9 is converted into the linear motion of the clamping jaw 4, so that the clamping jaw 4 slides along the sliding groove 7 until the workpiece is clamped.
[0046] When machining workpieces of different lengths, the operator can adjust the height of the stop disc 12 to adapt to workpieces of different lengths. By starting the telescopic rod 10 to drive the traction column 11 to move in the length direction of the clamping pipeline 5, the height of the stop disc 12 in the clamping pipeline 5 is adjusted.
[0047] Finally, the lifting path of the stop disc 12 is limited by the clamping groove to ensure that the movement of the stop disc 12 in the clamping pipeline 5 does not exceed the predetermined range, and to avoid the stop disc 12 from shaking, thereby ensuring the stability of the workpiece during machining.
