Description

Technical Field

[0001] The invention relates to the technical field of numerically controlled machine tools, in particular to an external rapid tool setting tool for numerically controlled lathes. Background Art

[0002] With the continuous innovation and development of modern military manufacturing industry, the precision of parts processing is getting higher and higher, and the requirements for processing efficiency are also getting higher and higher. Shortening the debugging time of equipment before processing and the clamping and alignment time of tools have a great impact on improving processing efficiency. When installing tools on the turret of CNC lathes, it is necessary to fix the blade on the tool holder and install the tool holder on the tool holder to fine-tune the angle. Workers need to check whether the tip of the blade is on the center axis of the tool holder by visual inspection or by radially marking the blade on the chuck or the workpiece. If the blade angle is offset, when cutting the end face, the tip of the tool passes through the machine tool spindle to form a conical boss on the end face of the workpiece, and the entire plane cannot be cut out. This requires adjusting the relative position relationship between the tool holder and the tool holder again. Therefore, the stability and efficiency of tool clamping and alignment before processing indirectly affect the processing efficiency. However, some equipment such as laser tool setting instruments and optical tool setting instruments are expensive, and some manufacturers cannot afford it. Summary of the invention

[0003] The purpose of the present invention is to provide a fast tool setting tool outside a CNC lathe to solve the problem that the tool setting is judged accurately by manual experience or visual and auditory senses, which lacks stability and consistency and leads to poor processing quality in later use.

[0005] When setting the tool, first install the blade on the tool handle of different lengths, and then install the tool handle in the tool handle mating groove on the tool holder base. According to the length of the tool handle, push the slider to translate the tool setting block to the bottom of the blade. After rotating the tool handle to fit the plane of the blade with the plane of the tool setting block, it can be determined that the tip of the blade has passed through the axis of the tool handle mating groove. Then use the screws to press the tool handle through the locking hole on the tool holder base to fix the tool handle to the tool holder base, and complete the off-machine tool setting work.

[0006] In order to better implement the present invention, further, an anti-skid pad is provided on the knife handle engagement groove to increase the friction between the knife handle and the knife seat base.

[0007] In order to better implement the present invention, further, a plurality of mounting holes are provided on a side of the knife seat base opposite to the locking hole, and screws are passed through the base and assembled on the mounting holes, so that the knife seat base is fixed on the base.

[0008] In order to better implement the present invention, further, a slider is provided on the knife seat base, the knife seat base is slidably connected to the base through the slider, and the sliding path of the knife seat base is parallel to the sliding path of the slider.

[0009] In order to better implement the present invention, further, the slide rail seat is provided with a plurality of through holes, and is assembled with the base by screws passing through the through holes.

[0010] In order to better implement the present invention, further, the knife seat base is made of 15-5PH stainless steel with a heat treatment hardness of HRC36-42.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] Embodiment 1: This embodiment provides a CNC lathe off-machine rapid tool setting tool, specifically, Figure 1-Figure 4 As shown, it includes a base 11, on which a slide rail seat 12 is detachably mounted, on which a slide rail is arranged, on which a slide block 13 is arranged, on which a tool setting block 14 is arranged, and on which a tool holder base 15 is detachably mounted on the base 11, on which a tool handle fitting groove is arranged, and on which a tool setting block 14 is arranged; on which a tool holder base 15 is detachably mounted, and on which a tool handle fitting groove is arranged, and on which a tool handle fitting groove axis is arranged; on which a plurality of locking holes 16 are arranged, and the size of the locking holes 16 is φ8.5 mm, and the locking holes 16 are perpendicular to the tool handle fitting groove axis. The tool holder base 15 is made of 15-5PH stainless steel, and the heat treatment hardness is HRC36-42.

[0022] This solution is used for tool setting before machining on ordinary CNC lathes or turret-type CNC machine tools. When setting the tool, first install the blade on a tool handle of varying lengths of 10 mm to 160 mm, select a tool holder base 15 of corresponding type according to the tool handle (the tool holder base 15 provided in this embodiment has tool holder engagement grooves of φ20 mm, φ40 mm, and φ50 mm, and the specifications of the tool holder base 15 are accurate simulations of the turret-type tool holder of a CNC lathe), and then insert the tool handle into the tool holder engagement groove on the tool holder base 15. In the groove, according to the length of the tool handle, manually push the slider 13 to translate the tool block 14 to the bottom of the blade. After manually rotating the tool handle to fit the blade plane with the tool block 14 plane, it can be determined that the tip of the blade has passed through the axis of the tool handle fitting groove. Then use the screw to press the tool handle through the locking hole 16 on the tool holder base 15 to fix the tool handle and the tool holder base 15. After that, the blade, tool handle and tool holder that have been positioned relative to each other can be directly installed on the machine tool for operation. In this way, stable and efficient tool setting work can be achieved outside the CNC lathe machine tool for tools with an overhang length of 10mm to 160mm.

[0023] Embodiment 2: This embodiment is further expanded on the basis of Embodiment 1. Figure 5 , Figure 6 As shown, the knife handle engaging groove is provided with an anti-skid pad 18 , and the anti-skid pad 18 is made of rubber, so as to increase the friction between the knife handle and the knife seat base 15 .

[0024] After the shank is inserted into the shank fitting groove, the shank is pressed down by screws through the locking holes 16 on the tool holder base 15 to fix the shank to the tool holder base 15. Since the screws press down the anti-skid pad 18, the anti-skid pad 18 presses down the shank, thereby effectively preventing the shank and the tool holder base 15 from rotating relative to each other, thereby ensuring the stability of subsequent cutting operations.

[0025] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0026] Embodiment 3: This embodiment is further expanded on the basis of the above embodiment. Figure 6 As shown, a plurality of mounting holes 17 are provided on the side of the knife seat base 15 opposite to the locking hole 16, and the knife seat base 15 is fixed on the base 11 by M6 screws passing through the base 11 and assembled on the mounting holes 17. The knife seat base 15 is fixed on the base 11 by M6 screws, which has good stability and is easy to disassemble.

[0027] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0028] Embodiment 4: This embodiment is further expanded on the basis of Embodiment 3. Figure 1 As shown, a slider is provided on the tool holder base 15 , and the tool holder base 15 is slidably connected to the base 11 via the slider, and the sliding path of the tool holder base 15 is parallel to the sliding path of the slider 13 .

[0029] When installing the tool holder base 15, the slider is used to cooperate with the slide groove on the base 11 to ensure that the axis of the tool handle engagement groove is parallel to the sliding track of the slider 13 during the initial installation, and it is also convenient for the mounting hole 17 and the corresponding M6 screw to be positioned and assembled, thereby improving the disassembly and assembly efficiency; due to the presence of the slider, when the tool holder base 15 is subjected to torque, the slider can withstand the torque alone, while the corresponding M6 screw will not, thereby preventing the M6 ​​screw from deformation.

[0030] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0031] Embodiment 5: This embodiment is further expanded on the basis of the above embodiment. Figure 4 As shown, the rail seat 12 is provided with a plurality of through holes, and 10 M6 screws are used to pass through the through holes to assemble with the base 11. By utilizing the quick disassembly and assembly of the M6 ​​screws, when the rail seat 12 and the slider 13 are damaged, they can be quickly replaced.

[0032] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0033] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the present invention.
