Numerical control blade machining clamping tool

Abstract

This utility model discloses a clamping fixture for CNC cutting tool machining, including a clamping mechanism and a protection mechanism. The clamping mechanism includes a support base, a cutting tool that fits against the top of the support base, two clamping plates that fit against the front and rear sides of the cutting tool and are inserted into the support base, a hexagonal bolt slidably connected between the two clamping plates, and a locking member screwed to the outer end of the hexagonal bolt. In this utility model, after the cutting tool body is clamped, the movable end of the control cylinder extends, so that the frame fits onto the cutting edge. Then, the pressure rod, under the pressure of the sleeve, tightly fits against the outside of the cutting edge. When the cutting edge contacts the object being cut, a distance sensor detects the distance between the frame and the object in real time. The contraction amplitude of the movable ends of the two cylinders is the same as the depth to which the cutting edge enters the object, thereby effectively protecting the parts of the cutting tool other than the cutting tool body and reducing the probability of cutting tool damage.

Description

Technical Field

[0001] This utility model relates to the field of clamping tooling technology, specifically to clamping tooling for CNC cutting tool machining. Background Technology

[0002] CNC cutting inserts are a general term for indexable turning inserts, and are the mainstream products in modern metal cutting applications. They are mainly used in turning, milling, parting-off grooving, and thread turning of metals. Based on material, they can be divided into coated inserts, cermet inserts, non-metallic ceramic inserts, carbide inserts, and superhard inserts. Their characteristics include high efficiency and high wear resistance, increasing machining efficiency by more than four times compared to traditional welded inserts and alloy inserts. With continuous advancements in coating technology, breakthroughs in key technologies for wear resistance and high-temperature resistance will further improve efficiency and reduce machining costs.

[0003] Currently used blade clamping fixtures mostly clamp the blade at the back of the blade. Although the clamping is secure, it lacks protection for the blade, making it very easy for parts other than the back of the blade to crack and be damaged during cutting. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A clamping fixture for CNC cutting tool machining includes a clamping mechanism and a protective mechanism. The clamping mechanism includes a support base, a cutting tool that fits against the top of the support base, two clamping plates that fit against the front and rear sides of the cutting tool and are inserted into the support base, a hexagonal bolt that is slidably connected between the two clamping plates, and a locking element that is screwed to the outer end of the hexagonal bolt. The protective mechanism includes a frame that is movably sleeved on the outside of the cutting tool, two cylinders connected between the support base and the frame, a distance sensor embedded in the top of the frame, multiple sleeves that pass through multiple corners of the frame, and a pressure rod that fits against the front and rear sides of the cutting tool and is connected between the two sleeves.

[0007] By adopting the above technical solution, after the blade body is clamped, the movable end of the control cylinder extends, so that the frame fits onto the blade edge. Then, the pressure rod is squeezed by the sleeve and fits tightly against the outside of the blade edge. When the blade edge contacts the object being cut, the distance sensor detects the distance between the frame and the object in real time. The contraction amplitude of the movable ends of the two cylinders is the same as the depth of the blade edge entering the object, thereby effectively protecting the parts of the blade other than the blade body and reducing the probability of blade damage.

[0008] In a preferred embodiment, the present invention can be further configured such that: the locking member is located on the front side of the support base, the locking member is composed of a nut and a rotating rod, the rotating rod is installed on one side of the nut, and the outer end of the rotating rod is machined into a spherical surface.

[0009] In a preferred embodiment, the present invention can be further configured such that two cylinders are located on both sides of the blade, and the two cylinders are connected in series.

[0010] In a preferred embodiment, the present invention can be further configured such that: the distance sensor is located on the rear side of the blade, and both the cylinder and the distance sensor are electrically connected to an external PLC.

[0011] In a preferred embodiment, the present invention can be further configured such that both ends of the pressure rod are bent, and the pressure rod is made of an elastic metal material.

[0012] In a preferred embodiment, this utility model can be further configured such that two springs are connected between the two clamping plates, both springs are located inside the support base and are vertically symmetrical about the hexagonal bolt.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, after the blade body is clamped, the movable end of the control cylinder extends, so that the frame fits onto the blade edge. Then, the pressure rod is squeezed by the sleeve and fits tightly against the outside of the blade edge. When the blade edge contacts the object being cut, the distance sensor detects the distance between the frame and the object in real time. The contraction amplitude of the movable ends of the two cylinders is the same as the depth of the blade edge entering the object, thereby effectively protecting the parts of the blade other than the blade body and reducing the probability of blade damage.

[0015] 2. In this utility model, the blade is placed between two clamping plates, and then the locking member is tightened. The locking member presses against the clamping plate that is close to it. Then, under the transmission of force, the two clamping plates form a clamping structure, which effectively fixes the back of the blade. The structure is simple and the clamping is convenient.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0026] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0027] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a clamping fixture for CNC cutting tool processing. Example

[0028] Combination Figure 1-5 As shown, the clamping fixture for CNC cutting tool processing provided by this utility model includes a clamping mechanism 100 and a protection mechanism 200. The clamping mechanism 100 includes a support base 110, a cutting tool 120 that is attached to the top of the support base 110, two clamping plates 130 that are respectively attached to the front and rear sides of the cutting tool 120 and inserted into the support base 110, a hexagonal bolt 140 that is slidably connected between the two clamping plates 130, and a locking member 150 that is screwed to the outer end of the hexagonal bolt 140.

[0029] The protection mechanism 200 includes a frame 210 movably sleeved on the outside of the blade 120, two cylinders 220 connected between the support base 110 and the frame 210, a distance sensor 230 embedded in the top of the frame 210, multiple sleeves 240 passing through multiple corners of the frame 210, and a pressure rod 250 respectively attached to the front and rear sides of the blade 120 and connected between the two sleeves 240.

[0030] Furthermore, the locking member 150 is located on the front side of the support base 110. The locking member 150 is composed of a nut 151 and a rotating rod 152. The rotating rod 152 is installed on one side of the nut 151. The outer end of the rotating rod 152 is machined into a spherical surface. The structural design of the locking member 150 makes it convenient for operators to rotate the locking member 150.

[0031] Furthermore, the pressure rod 250 is bent at both ends and is made of elastic metal material. The shape design of the pressure rod 250 can firmly fit the blade part of the blade 120, effectively improving the stability of the blade 120 when cutting.

[0032] Furthermore, two springs 300 are connected between the two clamping plates 130. Both springs 300 are located inside the support base 110 and are vertically symmetrical about the hexagonal bolt 140. The springs 300 can open the two clamping plates 130 to facilitate the installation of the blade 120. Example

[0033] Combination Figure 1 and Figure 4 As shown, based on Embodiment 1, two cylinders 220 are located on both sides of the blade 120, and the two cylinders 220 are connected in series. The series design allows the two cylinders 220 to work synchronously, effectively preventing the frame 210 from getting stuck during lifting. Example

[0034] Combination Figure 1-5 As shown, in the above embodiment, the distance sensor 230 is located on the rear side of the blade 120. Both the cylinder 220 and the distance sensor 230 are electrically connected to an external PLC. Using an external PLC can improve the intelligence of this device during use and enhance the comfort of using the device.

[0035] The working principle and usage process of this utility model are as follows: In the initial state, the locking member 150 is at the outermost end of the hexagonal bolt 140. Then, the two ends of the spring 300 press the two clamping plates 130, making the two clamping plates 130 as far apart as possible. Then, the blade 120 is placed between the two clamping plates 130, with the back of the blade 120 in contact with the top of the support base 110. Then, the locking member 150 is tightened, and the nut 151 presses the clamping plate 130 close to it. Then, under the transmission of force, the two clamping plates 130 move closer together and clamp the blade 120. Then, the control... The movable end of the cylinder 220 extends, allowing the frame 210 to fit over the blade 120. Then, under the pressure of the two sleeves 240, the pressure rod 250 fits against the blade 120. The two pressure rods 250 cooperate to form a clamping mechanism for the blade. When the blade contacts the object being cut, the distance sensor 230 detects the distance between the frame 210 and the object in real time. The contraction amplitude of the movable ends of the two cylinders 220 is the same as the depth to which the blade enters the object, thereby effectively protecting the parts of the blade 120 other than the blade body and reducing the probability of damage to the blade 120.

[0036] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
