Description

Technical Field

[0001] This utility model relates to the field of lathe technology, specifically to a lathe tool post. Background Technology

[0002] The lathe tool post is an important component on a lathe, mainly used to mount and fix cutting tools, and to ensure that the tools maintain a stable and precise position during machining. It plays a key role in turning operations, directly affecting machining accuracy and efficiency.

[0003] Traditional square tool holders use bolt fastening, requiring manual tightening of multiple screws each time a tool is changed. This operation is cumbersome and time-consuming. In addition, existing tool holders lack a quick fine-tuning mechanism, making it impossible to correct the tool height in real time during machining, which affects the machining efficiency of the lathe. Utility Model Content

[0004] The purpose of this utility model is to provide a lathe tool post to solve the problems mentioned in the background art. The traditional square tool post uses bolt fastening, which requires manually tightening multiple screws every time the tool is changed. This operation is cumbersome and time-consuming. At the same time, the existing tool post lacks a quick fine-tuning mechanism, which cannot correct the tool height in real time during the machining process, thus affecting the machining efficiency of the lathe.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lathe tool post, comprising a base and a clamping part:

[0006] The clamping part is located on the top of the base. The clamping part has a clamping frame that is vertically slidably mounted on the top of the base for clamping the tool. A slider is horizontally slidably mounted inside the base. The slider is engaged with the clamping frame. The slider moves to fix the position of the clamping frame. A transmission rod is vertically slidably mounted on the top of the base. The transmission rod is slidably connected to the slider. The transmission rod moves to drive the slider to move.

[0007] By adopting the above technical solution, the up-and-down movement of the transmission rod can drive the slider to move laterally, so that the slider can engage or disengage with the clamping frame, thereby realizing the rapid clamping or release of the tool and improving the tool changing efficiency.

[0008] Preferably, the base also has a slot on the top of the base, and the clamp is vertically embedded in the slot and slidably connected to the base vertically.

[0009] By adopting the above technical solution, the clamping frame can be precisely guided by the slot, ensuring stable sliding of the clamping frame in the vertical direction and preventing the tool from deviating during the machining process.

[0010] Preferably, there are two clamping parts, and the two clamping parts are designed in a mirror symmetrical manner along the center of the base.

[0011] By adopting the above technical solution, dual tool position switching can be achieved through symmetrically arranged clamping parts, improving machining flexibility, reducing tool change time, and making it suitable for multi-process continuous machining.

[0012] Preferably, the base also has a groove a inside the base, the slider is embedded in the groove a and is laterally slidably connected to the base, and a spring a is provided at one end of the slider, the spring a being located between the base and the slider.

[0013] By adopting the above technical solution, the movement trajectory of the slider can be restricted by the slide groove a, ensuring the stability of its lateral movement. At the same time, the spring a provides a reset force, so that the slider automatically returns to its original position when no force is applied, thereby improving the reliability of the clamping mechanism.

[0014] Preferably, the base also has a groove b formed inside the base, the transmission rod is vertically embedded in the groove b and slidably connected to the base laterally, and a spring b is provided at the bottom of the transmission rod, the spring b being located between the base and the transmission rod.

[0015] By adopting the above technical solution, the vertical movement of the transmission rod can be guided by the slide groove b, ensuring the linkage accuracy between the transmission rod and the slider. At the same time, the spring b provides an upward restoring force, so that the transmission rod maintains its initial position when no external force is applied, which facilitates operation.

[0016] Preferably, the clamping part also has a locking tooth a disposed on the side of the clamping frame, and a locking tooth b disposed at the end of the slider near the clamping frame, wherein the locking tooth a and the locking tooth b are engaged and connected.

[0017] By adopting the above technical solution, the clamping frame can be locked by the meshing of clamping teeth a and b, ensuring that the tool will not loosen during the machining process, thereby improving machining accuracy and safety.

[0018] Preferably, the number of teeth of the locking tooth b is greater than the number of teeth of the locking tooth a.

[0019] By adopting the above technical solution, the clamping tooth b can effectively mesh with the clamping tooth a when the clamping frame is at any height position in the slot.

[0020] Preferably, the clamping part also has a sliding shaft disposed inside the slider, and the transmission rod has a guide groove inside, the sliding shaft being embedded in the guide groove and slidably connected to the transmission rod.

[0021] By adopting the above technical solution, the vertical movement of the transmission rod can be converted into the lateral movement of the slider through the cooperation of the sliding shaft and the guide groove, thereby realizing the transmission of force and the conversion of direction, and ensuring the smooth operation of the clamping mechanism.

[0022] Compared with the prior art, the beneficial effects of this utility model are: by providing a clamping part, the slide block can be moved laterally by the up and down movement of the transmission rod, so that the slide block can be engaged or disengaged from the clamping frame, thereby realizing the quick clamping or release of the tool and improving the tool changing efficiency. The symmetrical arrangement of the clamping parts enables the switching of dual tool positions, improving the processing flexibility, reducing the tool changing time, and is suitable for multi-process continuous processing.

[0030] 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.

[0031] Example 1

[0032] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a technical solution: a lathe tool post, including a base 1 and a clamping part 2.

[0033] The clamping part 2 is located on the top of the base 1. The clamping part 2 has a clamping frame 201 that is vertically slidably mounted on the top of the base 1 for clamping the tool. A slider 202 is horizontally slidably mounted inside the base 1. The slider 202 is engaged with the clamping frame 201. The slider 202 moves to fix the position of the clamping frame 201. A transmission rod 203 is vertically slidably mounted on the top of the base 1. The transmission rod 203 is slidably connected with the slider 202. The transmission rod 203 moves to drive the slider 202 to move. The up and down movement of the transmission rod 203 can drive the slider 202 to move horizontally, so that the slider 202 engages or disengages from the clamping frame 201, thereby realizing the rapid clamping or release of the tool and improving the tool changing efficiency.

[0034] Example 2

[0035] Please see Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: a lathe tool post, including a clamping part 2, a slider 202, and a transmission rod 203.

[0036] A slot 101 is vertically provided on the top of the base 1. The clamping frame 201 is vertically embedded in the slot 101 and vertically slidably connected to the base 1. The slot 101 can accurately guide the clamping frame 201, ensuring stable sliding of the clamping frame 201 in the vertical direction and preventing the tool from deviating during the machining process.

[0037] There are two clamping parts 2, which are designed in a mirror symmetrical manner along the center of the base 1. The dual tool position switching can be achieved through the symmetrically arranged clamping parts 2, which improves the machining flexibility, reduces the tool change time, and is suitable for multi-process continuous machining.

[0038] A horizontal groove a102 is provided inside the base 1. The slider 202 is embedded in the groove a102 and is slidably connected to the base 1. A spring a208 is provided at one end of the slider 202. The spring a208 is located between the base 1 and the slider 202. The groove a102 can limit the movement trajectory of the slider 202 and ensure its lateral movement stability. At the same time, the spring a208 provides a reset force so that the slider 202 automatically returns to its original position when no force is applied, thereby improving the reliability of the clamping mechanism.

[0039] A vertical groove b103 is provided inside the base 1. The transmission rod 203 is vertically embedded in the groove b103 and is slidably connected to the base 1 laterally. A spring b209 is provided at the bottom of the transmission rod 203. The spring b209 is located between the base 1 and the transmission rod 203. It can guide the vertical movement of the transmission rod 203 through the groove b103 to ensure the linkage accuracy between the transmission rod 203 and the slider 202. At the same time, the spring b209 provides an upward restoring force so that the transmission rod 203 maintains its initial position when no external force is applied, which is convenient for operation.

[0040] A locking tooth a204 is integrally provided on the side of the clamping frame 201, and a locking tooth b205 is provided at the end of the slider 202 near the clamping frame 201. The locking tooth a204 and the locking tooth b205 are engaged and connected. The clamping frame 201 can be locked by the engagement of the locking tooth a204 and the locking tooth b205, ensuring that the tool will not loosen during the machining process, thereby improving machining accuracy and safety.

[0041] The number of teeth of the clamping tooth b205 is greater than the number of teeth of the clamping tooth a204, so that the clamping tooth b205 can effectively engage with the clamping tooth a204 when the clamping frame 201 is at any height position in the slot 101.

[0042] A sliding shaft 206 is integrally provided inside the slider 202, and a guide groove 207 is provided inside the transmission rod 203. The sliding shaft 206 is embedded in the guide groove 207 and slidably connected to the transmission rod 203. Through the cooperation of the sliding shaft 206 and the guide groove 207, the vertical movement of the transmission rod 203 is converted into the lateral movement of the slider 202, realizing the transmission of force and the conversion of direction, and ensuring the smooth operation of the clamping mechanism.

[0043] Working principle: First, the operator loads the tool into the clamping frame 201 and secures it with bolts. Then, the operator presses down on the transmission rod 203, causing it to move vertically downward along the slide groove b103 against the spring b209. This allows the sliding shaft 206 to slide within the guide groove 207, and the slider 202 to overcome the elastic force of the spring a208, causing the retaining tooth a204 to retract into the base 1. Then, the vertical position of the clamping frame 201 within the slot 101 is adjusted according to the machining requirements. When it is necessary to lock the tool, the operator releases the transmission rod 203, causing it to be lifted by the spring b209. The guide groove 207 inside the transmission rod 203 pushes the sliding shaft 206 to move laterally, causing the slider 202 to move along the slide groove a103. 2. Slide the slider 202 towards the clamping frame 201. As the slider 202 moves, the locking teeth b205 at its end engage tightly with the locking teeth a204 on the side of the clamping frame 201, thereby firmly locking the clamping frame 201 at the current height position. When it is necessary to release the tool or adjust the height, press the transmission rod 203 down again, so that the transmission rod 203 overcomes the spring b209 and moves vertically down along the slide groove b103, thereby allowing the slide shaft 206 to slide in the guide groove 207, and allowing the slider 202 to overcome the elastic force of the spring a208, causing the locking teeth a204 to retract into the base 1, so that the locking teeth b205 and locking teeth a204 disengage. At this time, the clamping frame 201 can slide and adjust freely to achieve quick tool change or height fine adjustment.
