Description

Technical Field

[0001] The utility model relates to the field of numerical control processing equipment, in particular to a laser tool setting instrument structure. Background Art

[0002] The laser tool setter is a tool that uses laser technology to achieve precise positioning between the tool and the workpiece. Its working principle is that the laser transmitter and receiver of the laser tool setter are fixed on both sides of the tool setter respectively. When the tool passes through the laser beam of the tool setter, the intensity of the beam irradiated on the receiver will change, thus generating a trigger signal to sense the state of the tool and cooperate with the software system of Dongfang Instrument to alarm or automatically compensate for the deviation of the tool. Since long-term use will cause the installation of the laser tool to loosen, the hardware error cannot be corrected by software, so a tool setter structure that can be manually calibrated is required.

[0003] Chinese patent CN220481099U discloses a laser tool setting instrument, including a support plate, a laser tool setting instrument is installed on the inner side of the support plate, a laser head is installed inside the two laser tool setting instruments, a micro electric push rod is installed inside the support plate, a connecting assembly is provided at the opposite ends of the two micro electric push rods, a No. 1 limit plate and a No. 2 limit plate are provided at the opposite ends of the two connecting assemblies, and auxiliary balls are rotatably connected to the surfaces of the opposite sides of the No. 1 limit plate and the No. 2 limit plate. Through the coordinated use of the support plate, the laser tool setting instrument, the laser head, the micro electric push rod, the connecting assembly, the No. 1 limit plate, the No. 2 limit plate, the auxiliary balls and the air gun head, the tool can be limited between the No. 1 limit plate and the No. 2 limit plate, and multiple auxiliary balls can be used to facilitate the tool limit without hindering the movement detection of the tool, thereby avoiding the tool from tilting and shaking.

[0004] There are still several points for improvement in the above documents: lack of protection for laser tools, the waste chips generated by parts processing will affect the detection accuracy; the splashing of cutting fluid during processing will penetrate into the interior of the laser tool along the connection between the tool and the processing table, causing damage to the workpiece.

Detailed implementation manners

[0024] To further understand the features, technical means, specific purposes and functions achieved by the present utility model, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0025] See Figures 1 to 6 As shown, a structure of a laser tool setter includes a protective shell 6, a tool setter 2 that generates laser, and a top cover 1 that rotatably closes the protective shell 6. The tool setter 2 includes an instrument base 3 for positioning and installation, an adjusting block 4 for manually calibrating the tool setter 2, and a cylinder 5 for controlling the telescopic movement of the tool setter 2 in the protective shell 6. The protective shell 6 is an irregular box body with a cavity. The top cover 1 is rotatably installed on the top of the protective shell 6. The tool setter 2 is arranged in the cavity. The instrument base 3 is installed at the bottom of the cavity of the protective shell 6 and is connected below the tool setter 2. The adjusting block 4 is installed on the surface of the protective shell 6 and passes through the outer wall of the protective shell 6 to be connected with the instrument base 3. The cylinder 5 is installed at the bottom of the cavity of the protective shell 6 and is connected with the tool setter 2 and the top cover 1.

[0026] This structure drives the tool setter 2 to extend and retract in the cavity of the protective housing 6 through the air cylinder 5. At the same time, the top cover 1 is connected to the air cylinder 5 to ensure that the top cover 1 can automatically open when the tool setter 2 extends out of the protective housing 6 and automatically close when it is retracted into the protective housing 6, effectively protecting the tool setter 2 during part processing and avoiding the influence of cutting fluid and waste chips on the accuracy of the tool setter 2. The adjustment block 4 is used to control the movement of the instrument base 3 in the protective housing 6, facilitating the precise adjustment of the detection position of the laser of the tool setter 2.

[0027] See Figure 3 As shown, a base 31, a stop block 32, a pressing plate 33 and a support rod 34 are connected to the instrument base 3. The base 31 is installed on the lower surface of the instrument base 3 and is in the cavity of the protective housing 6. The stop block 32 is installed at the bottom of the cavity of the protective housing 6 and is connected to the base 31. The pressing plate 33 is installed on the inner wall of the protective housing 6 and is connected to the side surface of the base 31. The support rod 34 is installed at the center of the upper surface of the instrument base 3.

[0028] The base 31 is used to position and install the instrument base 3. The stop block 32 is used to limit the movement range of the instrument base 3 on the base 31, avoiding the tool setter 2 being stuck by the protective housing 6 and unable to retract due to excessive lateral movement. The pressing plate 33 is used to press the instrument base 3 onto the base 31 to prevent the installation from loosening during long-term use and affecting the detection accuracy. The support rod 34 is used to support the extension and retraction of the tool setter 2 on the instrument base 3.

[0029] See Figure 3 As shown, a linear sliding groove 311 is provided on the base 31, and a limit pin 312 is provided on the side surface of the instrument base 3. The linear sliding groove 311 is arranged on the upper surface of the base 31 and is fitted with the bottom of the instrument base 3.

[0030] The linear sliding groove 311 provides guidance for the movement of the instrument base 3 on the base 31. The limit pin 312 is used to position and install the adjustment block 4, facilitating the adjustment block 4 to control the movement distance of the instrument base 3.

[0031] See Figures 1 to 4 As shown, a rotating rod 41 and a knob 42 are provided on the adjustment block 4. One end of the rotating rod 41 is inserted into the outer walls of the adjustment block 4 and the protective housing 6 and is connected to the instrument base 3, and the other end is installed with the knob 42.

[0032] By rotating the knob 42 on the adjustment block 4, the telescopic movement of the rotating rod 41 on the adjustment block 4 is controlled. The telescopic movement of the rotating rod 41 drives the instrument base 3 to move in the linear sliding groove 311 on the base 31. Rotating and adjusting the length of the rotating rod 41 can not only precisely control the telescopic distance but also avoid the displacement of the instrument base 3 caused by the vibration during part processing.

[0033] See Figures 1 to 5 As shown, a push rod 53 is installed at the center of the air cylinder 5, a rear frame 52 is installed at the bottom of the air cylinder 5, and a connecting plate 51 is installed at the top of the push rod 53. The connecting plate 51 is in contact with the bottom of the tool setter 2.

[0034] The rear frame 52 is used to reduce the contact area between the cylinder 5 and the protective housing 6, avoiding large vibrations on the protective housing 6 when the cylinder 5 operates. The push rod 53 drives the connecting plate 51 to expand and contract under the action of the cylinder 5. Since the connecting plate 51 is connected to the bottom of the tool setter 2, the expansion and contraction of the connecting plate 51 drives the expansion and contraction of the tool setter 2.

[0035] See Figure 6 As shown, a connecting rod 511, a rocker 512 and a rotating interface 513 are connected to the connecting plate 51. The connecting rod 511 is installed on the side of the connecting plate 51, and a rotating interface 513 is provided at the top of the connecting rod 511. The rocker 512 is inserted into the rotating interface 513 and fixedly connected to the top cover 1.

[0036] Since the top cover 1 is also connected to the connecting plate 51, when the tool setter 2 expands and contracts, the top cover 1 can open or close the protective housing 6 synchronously, ensuring the integrated installation of the tool setter 2 and the top cover 1. When the connecting plate 51 rises, the connecting rod 511 drives the movement of the rocker 512 through the rotating interface 513 to control the opening of the top cover 1. When the connecting plate 51 descends, the connecting rod 511 pulls the rocker 512 to close the top cover 1.

[0037] See Figure 5 As shown, an air chamber 531 is provided inside the cylinder 5. The proximity switch 533 is installed at the bottom of the push rod 53, and the throttle valve 532 is provided on the rear frame 52 and communicated with the air chamber 531.

[0038] The throttle valve 532 is used to control the flow rate of the gas in the air chamber 531 to control the movement speed of the cylinder 5. Since the push rod 53 expands and contracts in the air chamber 531 as the cylinder 5 moves, a proximity switch 533 is provided at the top of the push rod 53 to further control the detection position of the laser on the tool setter 2.

[0039] See Figure 1 and Figure 2 As shown, a bracket 61 and a waterproof interface 62 are provided on the protective housing 6. The bracket 61 is installed on the side of the protective housing 6 and is below the adjustment block 4. The waterproof interface 62 is provided on the side of the protective housing 6 and is on the same side of the protective housing 6 as the bracket 61. The rotating shaft 63 is provided at the top of the protective housing 6 and is connected to both sides of the top cover 1.

[0040] The bracket 61 is used to install the entire tool setting instrument structure on the processing tool. The waterproof interface 62 is used to prevent cutting fluid from flowing into the protective housing 6. The rotating shaft 63 serves as the rotation center of the top cover 1.

[0041] The above embodiments merely represent one or several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several variations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the appended claims.
