Abstract
Description
Technical Field
[0001] This utility model is applied to the field of mechanical equipment, especially the field of CNC horizontal turning and milling, and specifically relates to a tool setting mechanism applied to horizontal turning and milling. Background Technology
[0002] CNC machine tools require frequent tool setting during machining to reduce the number of trial cuts and improve accuracy. As a multi-functional machining center, the horizontal milling and turning machine has made the tool setting device a basic standard feature.
[0003] Currently used contact tool setters are mostly fixed structures, occupying space in the machining area and easily interfering with the workpiece. In addition, since the tool setter is exposed to the working environment during equipment processing, it often gets contaminated with dust and machining debris. The machining debris can also directly impact the tool setter, causing damage and affecting the tool setting accuracy and the tool setter's lifespan. Utility Model Content
[0004] Purpose of the utility model: In order to overcome the shortcomings of the prior art, this utility model provides a tool setting mechanism for horizontal milling and turning, which achieves efficient and accurate tool calibration through optimized mechanical structure design.
[0005] Technical solution: A tool setting mechanism for horizontal milling and turning, comprising a linear guide fixing bracket, linear guide, linear guide seat, slider pressure block, linear guide pressure plate, tool setting device seat, cylinder connecting plate, buffer bracket, cable chain groove, tool setting device air circuit board, floating joint, buffer, cylinder, tool setting device, tank chain and cable chain fixing bracket.
[0006] The linear guide fixing bracket is fixed on the machine tool casting, the linear guide fixing bracket is equipped with a linear guide seat, and the linear guide is installed on the linear guide seat;
[0007] The tool setter base is fixedly connected to the rail base, and the tool setter is fixedly installed on the tool setter base; the tool setter air circuit board is fixedly installed on the back of the rail fixing bracket.
[0008] The cylinder is connected to the linear rail fixing bracket via a cylinder connecting plate at the end; the cylinder connecting plate is mounted on the linear rail seat; one end of the floating joint is connected to the cylinder, and the other end is connected to the cylinder connecting plate.
[0009] The buffer is connected to the buffer bracket and then fixedly installed on the same plane as the cylinder;
[0010] The cable chain groove is installed above the rail fixing bracket, and the pneumatic cable chain fixing bracket is fixedly installed on the rail seat. Both the pneumatic cable chain fixing bracket and the cable chain groove are connected to the tank chain.
[0011] As an optimization: the two sliders and slider pressure blocks in the linear guide are installed on the linear guide fixing bracket.
[0012] As an optimization: the linear guide and the linear guide pressure plate in the linear guide are installed on the linear guide seat.
[0013] As an optimization: when the machine tool tool needs to be set, the tool setter begins to extend under the combined action of the cylinder, linear guide, and slider. After the cylinder connecting plate touches the linear guide fixing bracket and reaches the hard limit, the tool setter will reach its maximum stroke.
[0014] As an optimization: after the tool setting function is completed, the tool setting device retracts under the drive of the cylinder. After the cylinder reaches its stroke, the tool setting device returns to its origin, thus realizing a complete automatic extension and retraction action.
[0015] Beneficial effects: The specific advantages of this utility model are as follows:
[0016] 1. This utility model uses a cylinder to drive a slider to perform linear reciprocating motion (extend and retract) along a guide rail, forming a closed-loop control link; a low-friction linear module is used between the slider and the guide rail to ensure smooth movement and no machining interference.
[0017] 2. This utility model adopts a mechanical telescopic design to effectively isolate foreign objects such as iron filings and coolant in the processing area, thus avoiding accuracy drift caused by sensor contamination.
[0018] 3. This utility model adopts a double slider connection, and the distributed load reduces the stress concentration at a single point, reduces the error of repeated positioning, and improves the tool setting accuracy.
[0019] 4. The structure of this utility model is hidden behind the safety protection, and the whole is installed in the non-machining area of the machine tool. The installation is not limited by the small space of the machine tool machining area, and the probe of the tool setter will not be affected by cutting fluid, iron filings, etc., which will reduce its service life.
[0020] 5. The structure of this utility model uses a linear guide and a slider to drive the tool setter to extend, resulting in greater stability and better tool setting accuracy.
[0021] 6. This utility model adds a linear guide slider to distribute the load and improve the overall accuracy. Due to friction and assembly gaps, the repeatability of a single slider is relatively large (±0.01~0.03mm). However, the double slider structure has two contact surfaces to share the load, reducing the impact of gaps. The repeatability can reach within ±0.005mm. In addition, the double guide rail can withstand large loads, reduce the risk of mechanism damage, and greatly improve the stability of the mechanism.
[0022] 7. This utility model optimizes and eliminates some complex structural components, reduces the number of operations required by operators, and is safer and more environmentally friendly.
[0023] 8. This utility model limits the position of the mechanism by soft and hard limiting, thereby improving the accuracy of repeated positioning and preventing structural damage caused by overtravel.
[0024] 9. This utility model uses high-strength welded parts to replace cast iron brackets, reducing processing steps by 30% and material costs by 15%.
[0025] 10. This utility model adopts a fixed-end slider + moving-end guide rail configuration, which reduces the size of the bracket by 20% and frees up space resources in the machine tool processing area. Attached Figure Description

[0033] The linear guide fixing bracket 1 is fixed to the machine tool casting. A linear guide seat 3 is mounted on the linear guide fixing bracket 1, and a linear guide 2 is mounted on the linear guide seat 3. Two sliders and a slider pressure block 4 in the linear guide 2 are mounted on the linear guide fixing bracket 1, and the linear guide and linear guide pressure plate 5 in the linear guide 2 are mounted on the linear guide seat 3. This utility model adopts a double slider structure, which improves repeatability and tool setting accuracy, reduces failure rate, increases service life, and reduces subsequent costs. In this utility model, the slider is the fixed end, and the guide rail is the moving end, reducing the size of the fixing bracket, optimizing the area to be processed by the bracket, and reducing costs.

[0036] The buffer 12 is connected to the buffer bracket 8 and then fixedly installed on the same plane as the cylinder 13.
[0037] The drag chain groove 9 is installed above the rail fixing bracket 1, and the pneumatic drag chain fixing bracket 16 is fixedly installed on the rail seat 3. Both the pneumatic drag chain fixing bracket 16 and the drag chain groove (9) are connected to the tank chain 15.
[0038] The working principle (fully automatic) of this utility model device is as follows:
[0039] like Figure 4 As shown, when the machine tool tool needs to be set, the tool setter 14 begins to extend under the combined action of the cylinder, linear guide, and slider. After the cylinder connecting plate 7 touches the linear guide fixing bracket 1 and reaches the hard limit, the tool setter will reach its maximum stroke.
[0040] like Figure 5 As shown, after the tool setting function ends, the tool setting device 14 retracts under the drive of cylinder 13. After cylinder 13 reaches its stroke, the tool setting device 14 returns to its origin, thus realizing a complete automatic extension and retraction action.
