Description

Technical Field

[0001] The utility model relates to the technical field of workpiece clamping, and particularly relates to a clamping tool for a turning and milling machine. Background Technique

[0002] The clamping tool for a turning and milling machine is a device used to fix and clamp workpieces on a turning and milling machine. It can ensure the stable position of the workpiece during the machining process, avoid displacement or rotation due to cutting force, so as to guarantee the machining accuracy and the quality of the workpiece surface. This tooling consists of parts such as a fixture body, jaws or chucks, a driving mechanism, positioning elements, and connecting elements. These components work together to adapt to workpieces of different sizes and shapes and meet different machining requirements. When designing, the characteristics of the workpiece, machining requirements, parameters of the turning and milling machine, as well as the convenience and safety of operation need to be considered. By using a suitable clamping tooling, the efficiency of turning and milling machining and the product quality can be effectively improved, and the labor intensity of workers can be reduced.

[0003] The existing Chinese patent (publication number: CN219362387U) proposes a clamping tooling, including a mounting frame erected on the surface of a conveyor belt. A hydraulic lifting rod is embedded on the surface of the mounting frame. The telescopic end of the hydraulic lifting rod is fixedly installed with a lifting plate. The left and right sides of the bottom end of the lifting plate are both fixedly installed with connecting plates. A positive and negative thread screw is rotatably connected between the two connecting plates. The left clamping rod and the right clamping rod are symmetrically thread-connected to the surface of the positive and negative thread screw. This clamping tooling uses the left clamping plate and the right clamping plate to clamp the circuit breaker. Subsequently, the circuit breaker is lifted by the contraction of the hydraulic lifting rod. The hydraulic push rod is used to drive the rack to move. The rack meshes with the gear disk, driving the right shaft rod to rotate, so as to achieve the purpose of flipping the circuit breaker.

[0004] In the above technical solution, during the flipping process, the flipping radius is small, so it has the advantage of high flipping efficiency. And after flipping, by extending the hydraulic lifting rod, the circuit breaker can be stably placed on the surface of the conveyor belt without causing damage to the surface of the circuit breaker, ensuring the product quality of the circuit breaker. However, the contact surface between the clamping component in the above device and the workpiece is too large, which affects the subsequent cutting machining of the workpiece, and only one workpiece can be machined each time, with too low efficiency. The clamping force is not stable enough by using a screw. Therefore, we propose a clamping tooling for a turning and milling machine. Content of the Utility Model

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Such as Figures 1 - 3As shown in the figure, a clamping tooling for a lathe and milling machine includes a base 1. A circular groove 2 is provided at the top of the base 1. A clamping assembly 3 is arranged on one side of the top of the base 1 close to the circular groove 2. The clamping assembly 3 includes a lifting block 31. The lifting block 31 slides in the circular groove 2. A first rotating shaft 32 is rotatably connected to the lifting block 31. A fixing rod 33 is rotatably connected to the first rotating shaft 32. A fixing seat 6 is arranged on one side of the top of the base 1 close to the fixing rod 33. A fourth rotating shaft 7 is rotatably connected to the fixing seat 6. A connecting rod 8 is connected to the fourth rotating shaft 7. The other side of the connecting rod 8 away from the fourth rotating shaft 7 is connected to a fifth rotating shaft 9. The fifth rotating shaft 9 is rotatably connected to the fixing rod 33. One side of the top of the fixing rod 33 is connected to a first arc plate 34. A second rotating shaft 35 is rotatably connected to the first arc plate 34. A second arc plate 36 is rotatably connected to the second rotating shaft 35. A universal shaft 37 is arranged on the other side of the second arc plate 36 away from the second rotating shaft 35. A pressing block 38 is rotatably connected to the universal shaft 37. A power assembly 5 is arranged at the bottom of the lifting block 31. The power assembly 5 includes a protective shell 51. A motor 52 is arranged inside the protective shell 51. The output end of the motor 52 is fixedly connected to a fixing shaft 53. A gear 54 is connected to the fixing shaft 53. A rack 56 is arranged on one side of the protective shell 51 close to the gear 54. The rack 56 is meshed with the gear 54. The top of the rack 56 is connected to the lifting block 31. By setting the power assembly 5, when the motor 52 is started to drive the fixing shaft 53 to rotate, the fixing shaft 53 drives the gear 54 to rotate, the gear 54 drives the rack 56 to slide and rise in the slide rail 55, and the rack 56 drives the clamping assembly 3 at the top to move. When the lifting block 31 rises, it will drive the two fixing rods 33 to move towards the side of the workpiece 10 through the arranged first rotating shaft 32. The workpiece 10 is pressed and clamped by the arranged pressing block 38. The direction can be adjusted according to the shape of the workpiece 10 through the arranged universal shaft 37;

[0032] Furthermore, as shown in Figure 1 the figure: Two limiting rods 11 are arranged on one side of the top of the base 1 close to the fixing seat 6. The workpiece 10 is arranged on the limiting rods 11. The workpiece 10 slides on the limiting rods 11. By setting the limiting rods 11, the workpiece 10 is limited and fixed to prevent the position from shifting during the cutting work;

[0033] In the above solution, there is also a problem that after the angle between the pressing block 38 and the second arc plate 36 is adjusted, during the downward pressing process, the second arc plate 36 cannot be fixed and is prone to shaking, as shown in Figure 3 and Figure 4As shown in the figure: A limiting component 4 is provided on one side of the top of the fixed rod 33 close to the first arc-shaped plate 34. The limiting component 4 includes a housing 41. Inside the housing 41, a support rod 42 is provided. The support rod 42 is fixed to the top of the first arc-shaped plate 34. A third rotating shaft 45 is rotatably connected to the support rod 42. A lever 43 is rotatably connected to the third rotating shaft 45. A connecting member 44 is connected to the lever 43. The connecting member 44 is fixed to the top of the second arc-shaped plate 36. An electric telescopic rod 46 is provided on the top of the first arc-shaped plate 34. The top of the electric telescopic rod 46 is connected to the lever 43. By providing the limiting component 4 and using the principle of the lever 43, the electric telescopic rod 46 can be opened to adjust and fix the angle of the second arc-shaped plate 36, preventing shaking and deviation.

[0034] In the above solution, there is still a problem that when the rack 56 moves up and down, it will shake and deviate, thus affecting the operation of the clamping component 3. For example, Figure 2 As shown in the figure: A slide rail 55 is provided on one side of the protective housing 51 close to the gear 54. The side of the rack 56 away from the gear 54 is slidably connected in the slide rail 55. By providing the slide rail 55, the rack 56 moves more stably during movement and will not shake or deviate.

[0035] Furthermore, as shown in Figure 1 the figure: There are two fixed rods 33. The two fixed rods 33 move away from each other. Support legs 12 are provided at the bottom of the base 1. By providing two fixed rods 33, two workpieces 10 can be clamped and processed simultaneously.

[0036] Working principle: As shown in Figure 1 - Figure 4 the figure, by providing a power component 5, starting the motor 52 drives the fixed shaft 53 to rotate. The fixed shaft 53 drives the gear 54 to rotate. The gear 54 drives the rack 56 to slide and rise in the slide rail 55. The rack 56 drives the clamping component 3 at the top to move. When the lifting block 31 rises, it will drive the two fixed rods 33 to move towards one side of the workpiece 10 through the provided first rotating shaft 32. The workpiece 10 is pressed and clamped by the provided pressing block 38. The direction can be adjusted according to the shape of the workpiece 10 through the provided universal shaft 37. By providing the limiting rod 11, the workpiece 10 is limited and fixed to prevent deviation during the cutting operation. By providing the limiting component 4 and using the principle of the lever 43, the electric telescopic rod 46 can be opened to adjust and fix the angle of the second arc-shaped plate 36, preventing shaking and deviation. By providing the slide rail 55, the rack 56 moves more stably during movement and will not shake or deviate.

[0037] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model.
