Abstract
Description
Technical Field
[0001] This invention relates to the field of machining technology, and in particular to a fixture for CNC insert machining equipment and the CNC insert machining equipment. Background Technology
[0002] CNC cutting inserts (also known as indexable inserts) are core consumable tool components in modern metal cutting. They are typically made of superhard materials such as cemented carbide, ceramics, or cubic boron nitride through precision pressing and sintering, and are widely used in CNC machine tool machining processes such as turning, milling, and drilling. During the manufacturing process of CNC cutting inserts, high-precision grinding and other secondary machining processes are required on all surfaces and cutting edges. These processes all require specialized fixtures for precise positioning and reliable clamping of the inserts to ensure consistency of machining references and operational stability. However, existing fixtures used for CNC cutting insert machining typically have positioning and clamping structures designed only for a single insert. A single clamping operation can only accommodate and fix one insert, making it impossible to achieve simultaneous positioning and batch machining of multiple inserts. When carrying out large-scale production, only a serial operation mode of clamping and processing one piece at a time can be adopted. This results in a low proportion of effective cutting time and long auxiliary time for CNC cutting tools, which seriously restricts the output capacity per unit time and makes it difficult to meet the production needs of modern manufacturing for large-volume and high-efficiency processing of CNC cutting tools.

[0022] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.
[0023] This invention discloses a fixture 10 applied to a CNC insert machining equipment. The CNC insert machining equipment may include a frame (not shown) and the fixture 10, with the fixture 10 detachably connected to the frame. During the manufacturing process of the CNC insert 20, the fixture 10 is used to clamp and fix the CNC insert 20. The frame may include a frame body and an actuator such as a robot arm mounted on the frame body. The frame body may be made of high-strength metal material (such as alloy steel) and installed on the ground to support and fix the fixture 10 and the actuator, ensuring the stable operation of the CNC insert machining equipment. The actuator may be a multi-axis linkage precision grinding module, laser processing module, or EDM module, etc., used to perform high-precision grinding, cutting, or shaping operations on the CNC insert 20 clamped on the fixture 10 to achieve the machining and shaping of the CNC insert 20. Specific embodiments of the frame and actuator can be selected from mature existing technologies, which will not be elaborated here.
[0024] refer to Figure 1 , Figure 2 , Figure 3and Figure 4 In some embodiments, the fixture 10 may include a mounting base 11, a first clamping assembly 12, and a second clamping assembly 13. The mounting base 11 has a clamping groove 11a extending along a first direction for placing a CNC tool set 30. The CNC tool set 30 includes at least two tools 20 sequentially stacked along the first direction. The first clamping assembly 12 is disposed on the mounting base 11 and includes a first pressing end 12a that is slidably fitted to the mounting base 11 and is retractable relative to the mounting base 11 along the first direction. The first pressing end 12a is used to press against one end of the CNC tool set 30. The second clamping assembly 13 is disposed on the mounting base 11 and includes a second pressing end 13a that is slidably fitted to the mounting base 11 and can extend and retract relative to the mounting base 11 in a first direction. The second pressing end 13a is used to press against the opposite end of the CNC tool set 30 so that the CNC tool set 30 is limited and fixed in the clamping groove 11a and protrudes from the end face of the mounting base 11. The portion of the CNC tool set 30 that protrudes from the end face of the mounting base 11 is used for the actuator to perform corresponding processes, such as grinding.
[0025] refer to Figure 1 , Figure 2 and Figure 5 The clamping groove 11a may include a first surface 11a1 and a second surface 11a2 extending along a first direction. Each blade 20 may have a first abutting surface 21 that matches the first surface 11a1 and a second abutting surface 22 that matches the second surface 11a2. Figure 5 As shown, since the first surface 11a1 and the second surface 11a2 of the clamping groove 11a together form a positioning reference, the first pressing end 12a presses against one end of the CNC tool set 30, and the second pressing end 13a presses against the other end of the CNC tool set 30. Furthermore, the first contact surface 21 of each tool 20 abuts against the first surface 11a1, and the second contact surface 22 abuts against the second surface 11a2, thereby positioning and fixing the CNC tool set 30 within the clamping groove 11a, thus ensuring positioning accuracy. It is understood that the specific structure of the clamping groove 11a can be adapted to the specifications or dimensions of the tool 20 to be processed. For example, the width of the clamping groove 11a can be increased according to the width of the tool 20 to ensure that the tool 20 can be accommodated and positioned within the clamping groove 11a.
[0026] refer to Figure 4 and Figure 6In some embodiments, the first clamping assembly 12 includes a first driving member 121 and a first pressing rod 122 linked to the output end of the first driving member 121. The first pressing rod 122 is slidably engaged with the mounting base 11 and has a first pressing end 12a at the end away from the first driving member 121. The mounting base 11 has a circumferentially closed first slide rail 11b, and the first pressing rod 122 passes through the first slide rail 11b and is slidably engaged with the first slide rail 11b. Specifically, the mounting base 11 includes a base 111 and an insert 112. The base 111 has a slot 1111, and the insert 112 is approximately rectangular and is embedded in the slot 1111. It can be detachably connected to the base 111 by means of threaded holes and bolts. The first driving member 121 can be detachably connected to the base 111 using a threaded hole and bolt or similar means. The first slide rail 11b extends from the side of the base 111 facing the first driving member 121 to the side of the insert block 112 opposite to the first driving member 121. The base 111 has a portion of the first slide rail 11b, and the insert block 112 has the other portion of the first slide rail 11b. The insert block 112 can be made of a wear-resistant material, such as high manganese steel, to ensure the movement accuracy of the first pressing rod 122. When the first slide rail 11b is excessively worn due to long-term friction, the damaged insert block 112 can be removed from the base 111 and replaced with a new insert block 112, without replacing the entire base 111, thereby reducing the maintenance cost of the fixture 10. In some embodiments, the first driving member 121 can be a cylinder, and the output end of the first driving member 121 is connected to the first pressing rod 122 to realize the extension and retraction of the first pressing end 12a in a first direction. In other embodiments, the first driving member 121 can be a hydraulic cylinder.
[0027] refer to Figure 3 , Figure 4 , Figure 5 and Figure 6In some embodiments, the base 111 has a mounting groove 111a. The mounting base 11 includes a positioning block 113 detachably connected to the base 111. The positioning block 113 is accommodated within the mounting groove 111a and has a clamping groove 11a that matches the shape of the CNC tool set 30. The CNC tool set 30 protrudes from the end face of the positioning block 113. The slot 1111 communicates with the mounting groove 111a, and in a second direction, the depth of the slot 1111 is greater than the depth of the mounting groove 111a, so as to hold the lower part of the insert 112 inside the base 111, ensuring the reliable positioning of the insert 112 in the base 111 and preventing the insert 112 from shaking during the movement of the first pressing rod 122. In some embodiments, the mounting base 11 has a third direction, and the first direction, the second direction, and the third direction are perpendicular to each other. Specifically, in the third direction, the positioning block 113 is detachably connected to the base 111 on one side of the clamping groove 11a by two or more first fasteners (not shown). Mounting base 11 includes a fixing block 114 detachably connected to base 111. The fixing block 114 is accommodated within mounting groove 111a and is located on the other side of clamping groove 11a in a third direction. The end of positioning block 113 away from fixing block 114 may have connecting holes 1131 spaced apart along a first direction. The bottom of mounting groove 111a has alignment holes 111a1 that match the connecting holes 1131. After the connecting holes 1131 and alignment holes are aligned, a first fastener is inserted. In some embodiments, the first fastener may be a bolt. The first fastener passes through the connecting hole 1131 and can be connected to mounting base 11 by threads or other means with the alignment hole 111a1, thereby initially positioning positioning block 113 on mounting base 11.
[0028] Furthermore, such as Figure 4 , Figure 5 , Figure 6As shown, the fixing block 114 can be fixed in the mounting groove 111a by means of threaded holes and bolts, and one of the fixing block 114 and the positioning block 113 has an abutment area 113a and the other has an abutment boss 114a. The abutment boss 114a has a first inclined surface 114a1 and the abutment area 113a has a second inclined surface 113a1. The first inclined surface 114a1 and the second inclined surface 113a1 are respectively parallel to the first direction and inclined to the second direction. The shape of the abutment boss 114a matches the abutment area 113a and is accommodated in the abutment area 113a, and the first inclined surface 114a1 abuts against the second inclined surface 113a1. In the above structural configuration, from the third-party direction, one end of the positioning block 113 is fixed to the mounting base 11 by a first fastener, and the other end of the positioning block 113 is pressed against the second inclined surface 113a1 by the first inclined surface 114a1 of the fixing block 114, thus fixing the positioning block 113 in the mounting groove 111a, thereby preventing the positioning block 113 from shaking or deflecting during operation. In particular, for cutting inserts 20 of different specifications, the positioning block 113 can be disassembled and replaced, thus eliminating the need to replace the entire fixture 10, thereby improving the versatility of the fixture 10 and reducing the processing cost of the fixture 10.
[0029] refer to Figure 3 , Figure 4 and Figure 7 In some embodiments, the second clamping assembly 13 includes a second driving member 131, a transmission rod assembly 132 linked to the output end of the second driving member 131, and a second pressing rod 133 linked to the transmission rod assembly 132. The second pressing rod 133 is slidably fitted to the mounting base 11 and has a second pressing end 13a at the end away from the transmission rod assembly 132. The mounting base 11 has a circumferentially closed second slide rail 11c, and the second pressing rod 133 passes through and slidably fits into the second slide rail 11c. In some embodiments, the second driving member 131 can be a cylinder, and the output end of the second driving member 131 drives the transmission rod assembly 132 to drive the second pressing rod 133 to slide along the second slide rail 11c to press against the CNC tool insert assembly 30. In other embodiments, the second driving member 131 can be a hydraulic cylinder.
[0030] Specifically, the transmission rod assembly 132 includes a first rod 1321 and a second rod 1322. One end of the first rod 1321 can be rotatably connected to the mounting base 11 by means of a pin and a pin hole, and the other end is rotatably connected to the output end of the second drive member 131 and one end of the second rod 1322. The other end of the second rod 1322 can be rotatably connected to the second pressing rod 133 by means of a pin and a pin hole. The second drive member 131 is rotatably connected to the mounting base 11 and is inclined in the first direction and tilted toward the side where the clamping groove 11a is located. In some embodiments, the mounting base 11 may include a first fixing member 115, a second fixing member 116, and a third fixing member 117. The second fixing member 116 is located between the first fixing member 115 and the third fixing member 117. The first fixing member 115 may have a second slide rail 11c and may be connected to the base 111 by means of threaded hole and bolt to form a mounting groove 111a. The second fixing member 116 may have an opening 1161. The output end of the second driving member 131 passes through the opening 1161 and may be rotatably connected to one end of the first rod 1321 and the second rod 1322 by means of hinge or other means. The second driving member 131 may be rotatably connected to the end of the third fixing member 117 away from the second fixing member 116 by means of pin and pin hole or other means.
[0031] like Figure 4 As shown, in the first direction, the second pressing rod 133, the second rod 1322, and the first rod 1321 are arranged sequentially. The first rod 1321 and the second rod 1322 can be tilted towards the second driving member 131 to form an angle, which can be greater than 90 degrees and less than 180 degrees. In related technologies, the above structural design adopts the principle of toggle linkage force amplification. When the output end of the second driving member 131 is lifted, it drives the second rod 1322 to rotate around the connection point between the second rod 1322 and the second pressing rod 133, and drives the first rod 1321 to rotate around the connection point between the first rod 1321 and the mounting base, so that the angle between the first rod 1321 and the second rod 1322 gradually increases and approaches 180° (i.e., the first rod 1321 and the second rod 1322 tend to be collinear). During this process, the first rod 1321 only undergoes angular displacement relative to the third fixing member 117, thereby converting the lifting motion of the second driving member 131 into the thrust of the second pressing rod 133 along the first direction, and achieving mechanical self-locking pressure maintenance when approaching 180 degrees.
[0032] Furthermore, combined Figure 8The second pressing end 13a has a limiting part 13a1. The end face of the limiting part 13a1 that abuts against the CNC cutting tool assembly 30 has two or more spaced anti-slip grooves 13a11. The limiting part 13a1 also has a protruding stop 13a12. These stop 13a12 prevents the second pressing rod 133 from moving too far towards the side where the second driving member 131 is located, thus preventing it from dislodging from the second slide rail 11c, thereby limiting the movement range of the second pressing rod 133. The anti-slip grooves 13a11 are provided on the end face abutting against the CNC cutting tool assembly 30 to increase the coefficient of friction and prevent the cutting tool 20 from slipping or shifting during processing.
[0033] During the use of the fixture 10 of the CNC cutting tool processing equipment, two or more cutting tools can be stacked sequentially in the clamping groove 11a along the first direction. The first pressing end 12a of the first clamping component 12 presses against one end of the CNC cutting tool group 30, and the second pressing end 13a of the second clamping component 13 presses against the opposite end of the CNC cutting tool group 30, thereby fixing the CNC cutting tool group 30 in the clamping groove 11a to achieve batch processing, thereby improving the production efficiency of the CNC cutting tool 20.
[0034] refer to Figure 4 , Figure 5 , Figure 6 and Figure 9 In some embodiments, the mounting base 11 includes a connecting plate 118 detachably connected to the base 111, a rotating shaft 119 fixedly connected to the fixed plate, and a base 11d rotatably engaged with the rotating shaft 119. In the second direction, the base 111, connecting plate 118, rotating shaft 119, and base 11d are arranged sequentially to adjust the tilt angle of the base 111 relative to the base 11d by the rotational engagement of the rotating shaft 119 and the base 11d, thereby adjusting the machining angle of the cutting insert 20 fixed in the clamping groove 11a, so as to improve the ease of use of the fixture 10. Specifically, the base 11d includes an integrally formed seat body 11d1 and two cantilever arms 11d2. Each cantilever arm 11d2 and the seat body 11d1 together form a rotating shaft hole 11d3. The opposite ends of the rotating shaft 119 are correspondingly inserted and slidably engaged with the rotating shaft hole 11d3 to realize the rotation of the base 111 relative to the base 11d. In some embodiments, the connecting plate 118 can be detachably connected to the base 111 by means of threaded holes and bolts, and the rotating shaft 119 and the connecting plate 118 can be fixedly connected by means of threaded fasteners or locating pins.
[0035] Furthermore, one end of the cantilever 11d2 is spaced apart from the base 11d1 to form a gap 11d4 communicating with the pivot hole 11d3. The cantilever 11d2 has a fastening hole 11d21 communicating with the gap 11d4, and the base 11d1 has a mating hole (not shown) matching the fastening hole 11d21. The fixture 10 includes a second fastener 14, which passes through the fastening hole 11d21, the gap 11d4, and the mating hole to adjust the width of the gap 11d4, thereby adjusting the clamping force on the pivot 119, adjusting the rotational resistance of the pivot 119 in the pivot hole 11d3, and thus achieving preliminary positioning of the base 111 relative to the base 11d, preventing the base 111 from easily rotating the base 11d. In some embodiments, the second fastener 14 can be a bolt, which passes through the fastening hole 11d21, the gap 11d4, and is threaded into the mating hole to adjust the width of the gap 11d4.
[0036] Furthermore, the fixture 10 includes a third fastener 15 and an adjusting member 16. The third fastener 15 is connected to the connecting plate 118 and the base 11d. One end of the adjusting member 16 is connected to the connecting plate 118, and the other end abuts against the base 11d to adjust the tilt angle of the base 111 relative to the base 11d in conjunction with the third fastener 15. In some embodiments, the third fastener 15 may be a bolt. The connecting plate 118 may have an adjusting hole 1181, and the base 11d1 may have a fixing hole 11d5 that matches the adjusting hole 1181 and is threaded into the third fastener 15. The third fastener 15 passes through the adjusting hole 1181 and is threaded into the fixing hole 11d5 to prevent the tilt angle of the base 111 relative to the base 11d from easily increasing. The adjusting member 16 may include a first rod portion 161, an abutment portion 162, and a second rod portion 163. The length of the first rod portion 161 is greater than the length of the second rod portion 163. The second rod portion 163 is used to abut against the base 11d. The first rod portion 161 may be connected to the connecting plate 118 by means of threads or the like, thereby adjusting the height of the abutment portion 162 and the second rod portion 163 protruding from the connecting plate 118, thereby adjusting the tilt angle of the base 111 relative to the base 11d.
[0037] refer to Figure 4 , Figure 6 and Figure 9In some embodiments, the base 11d includes two connecting portions 11d6 protruding from opposite sides of the base body 11d1 along a first direction. Each connecting portion 11d6 has an arc-shaped through groove 11d61 and a scale 11d62 corresponding to the arc-shaped through groove 11d61. The arc-shaped through groove 11d61 is used to fix the fixture 10 to the frame of the CNC cutting tool processing equipment. Specifically, the two connecting parts 11d6 can be integrally formed with the base 11d and protrude from the opposite sides of the base body 11d1 along the first direction, and are located at the end of the base 11d away from the base 111. Each connecting part 11d6 has an arc-shaped through groove 11d61 extending along the third direction, and a scale 11d62 corresponding to the arc-shaped through groove 11d61. The arc-shaped through groove 11d61 can be matched with a specific structure of the frame, such as a through hole, and can be fixed to the frame of the machine frame by using threaded fasteners such as bolts. The arc-shaped through groove 11d61 and the scale 11d62 are used for the user to adjust the installation angle of the fixture 10 relative to the actuator or the frame, thereby adjusting the processing angle of the cutting tool 20 fixed in the clamping groove 11a relative to the actuator, improving the ease of use of the fixture 10.
