Description

Technical Field

[0001] This utility model belongs to the technical field of tool adjusters, specifically relating to a portable tool adjuster device that can be assembled and disassembled. Background Technology

[0002] my country's manufacturing industry is at a critical stage of transformation towards high-end and intelligent manufacturing. Industries such as automobiles, aerospace, and precision electronics are experiencing a surge in demand for efficient and high-precision machining equipment. As a core component of machining, the precision of cutting tools directly affects product quality. During workpiece machining, workers need to repeatedly adjust and measure the radial runout of the cutting tools, which is time-consuming and results in long tool adjustment times, thus hindering the improvement of production efficiency.

[0003] Therefore, the above problems urgently need to be solved. Utility Model Content

[0004] Purpose of the utility model: In order to overcome the above shortcomings, this utility model provides a portable tool adjuster that can be assembled and disassembled, which can quickly disassemble the various parts of the device for easy storage and transportation, and can quickly install and remove tools, thereby improving measurement efficiency and production efficiency.

[0005] Technical Solution: To achieve the above objectives, this utility model provides a portable, assembleable and detachable knife adjuster device, including a base. A first base platform and a second base platform are detachably connected to the top surface of the base via fasteners. A column is detachably connected to the top surface of the first base platform via fasteners. The column connects to a first positioning mechanism and a measuring mechanism. A second positioning mechanism is connected to the top surface of the second base platform. The first and second positioning mechanisms are arranged opposite to each other, and the measuring mechanism is located between the first and second positioning mechanisms. The first positioning mechanism is connected to the column via a support arm. A first through hole is provided at the end of the support arm away from the column. The first positioning mechanism is connected to the first through hole. A pull rod is connected to the upper end of the first positioning mechanism, which pulls the first positioning mechanism, causing it to move along the first through hole. To ensure accurate connection, positioning pins are connected between the base and the first and second base platforms, and between the first base platform and the column. The specific position of the positioning pins can be adjusted according to actual conditions.

[0006] This invention is mainly used for the inspection and adjustment of detachable inserts, including boring bars, milling cutters, deep hole drills, and step drills. It is used to detect the radial runout of inserts after initial installation or replacement, ensuring tool accuracy and preventing deviations due to installation issues. Typically, to ensure tool stability and accuracy during machining, both ends of the tool have central positioning holes. In this invention, the tool is placed on top of a second positioning mechanism, with its positioning head extending into the tool's central positioning hole. Pulling the lever lifts the first positioning mechanism, placing the end of the tool away from the second positioning mechanism below it. Pulling the lever again causes the first positioning mechanism to extend into the tool's central positioning hole. The first and second positioning mechanisms then position and fix the tool through the central positioning hole. A measuring mechanism is then used to inspect the insert. If the radial runout exceeds the tolerance, pulling the lever lifts the first positioning mechanism, removes the tool, and re-adjusts and reinstalls it. This invention improves the convenience of tool installation and removal by fixing the tool with a lever, shortens inspection time, and increases tool adjustment efficiency and production efficiency. Meanwhile, this utility model sets the entire device into three parts: a base, a first base platform, and a second base platform. The first base platform and the second base platform can be disassembled and separated from the base, which facilitates storage and transportation and improves the convenience of the device.

[0007] Furthermore, in the aforementioned assembleable and detachable portable tool adjuster device, an upper positioning block and a lower positioning block are respectively provided on the upper and lower sides of the first through hole. Each of the upper and lower positioning blocks has a through hole, which is coaxially arranged within the first through hole. The first positioning mechanism includes a first center, a shaft, and a pull pin. The shaft is connected to the first center, and the end of the shaft away from the first center is threadedly connected to the pull pin. The head of the pull pin is located within a countersunk through hole in the upper positioning block. A spring is fitted onto the pull pin, with both ends of the spring abutting against countersunk holes on the top surface of the shaft and the bottom surface of the upper positioning block, respectively. The shaft is connected within the first through hole and can move along it. When the pull rod lifts the pull pin, the spring compresses; when the pull rod is released, the spring applies a thrust to the shaft, causing the first center to move downwards. The spring then causes the first center to abut against the tool, ensuring tool positioning. The shaft and the pull stud are threaded together. Rotating the pull stud causes the shaft to extend. Adjusting the height of the first center ensures that after the pull rod is released, the first center applies a certain holding force to the tool, ensuring the stability of the tool positioning.

[0008] Furthermore, in the aforementioned assembleable and detachable portable tool adjuster device, the upper positioning block is provided with a rocker slot, and a rocker block is hinged within the rocker slot. The rocker block has a rocker portion located below the head of the pull stud. A pull rod is connected to the end of the rocker block away from the pull stud, and the pull rod is inclined. When it is necessary to lift the first center point, the pull rod is pressed down, causing the pull rod to rotate. The rotation of the rocker block causes the rocker portion to move upward, pushing the pull stud upward. The pull stud then lifts the shaft and the first center point, allowing the tool to be installed. The rocker block acts as a lever, allowing the operator to overcome the spring force and move the first center point with less force, improving operational convenience.

[0009] Furthermore, in the aforementioned assembleable and detachable portable tool adjuster device, the shaft portion is provided with a first guide groove, which is arranged axially along the shaft portion. The lower positioning block is provided with a first threaded through hole, which is arranged radially along the shaft portion. A set screw is internally threaded into the first threaded through hole, and the set screw extends into the first guide groove. During the upward or downward movement of the shaft portion, the set screw moves along the first guide groove, restricting the rotation of the shaft portion and ensuring the straightness and stability of the movement of the first center point.

[0010] Furthermore, in the aforementioned assembleable and detachable portable tool adjuster device, the second positioning mechanism includes a second center and a bushing. The bushing is connected to the outside of the second center, and its upper end is provided with an external thread. An adjusting ring is threadedly connected to the upper end of the bushing. The second base platform is provided with a second through hole, which is vertically arranged, and the bushing is slidably connected within the second through hole. A thrust bearing is provided in a groove on the top of the second base platform, and the thrust bearing is located between the adjusting ring and the second base platform. A second guide groove is vertically provided on the outer wall of the bushing, and a second threaded through hole is provided on the side wall of the second base platform. The second threaded through hole is arranged radially along the bushing, and a set screw is threadedly connected to the second threaded through hole, extending into the second guide groove. The outer diameter of the adjusting ring is larger than the outer diameter of the top of the second base platform. When the cutting tool is installed between the first and second positioning mechanisms, rotating the adjusting ring prevents the bushing from rotating due to the set screw extending into the second guide groove. The adjusting ring drives the bushing to rise or fall, which in turn drives the second center to rise or fall, accommodating cutting tools of different lengths, adjusting preload, or meeting testing requirements. A thrust bearing is incorporated to reduce friction between the adjusting ring and the second base, making adjustment easier and smoother.

[0011] Furthermore, in the aforementioned assembleable and detachable portable tool adjuster device, the measuring mechanism includes a measuring support plate, a detection rod, and a sleeve. The measuring support plate and the column are slidably connected, and the measuring support plate is threaded with a locking screw. The measuring support plate and the sleeve are connected, and the detection rod is slidably connected within a through hole in the sleeve. A dial indicator is connected to the sleeve, and the detection rod and the dial indicator connected to the sleeve abut against each other. During measurement, the detection rod transmits the detected radial runout of the tool to the dial indicator connected to the sleeve.

[0012] The measuring support plate and column are slidably connected and locked in place with locking screws, enabling the measuring mechanism to detect different height positions of the cutting tool and improving the flexibility of the device. Simultaneously, the measuring rod abuts against the cutting tool, transmitting the radial runout of the tool to the dial indicator, reducing wear on the dial indicator and extending its service life. Furthermore, by replacing the measuring rod with different lengths, it can accommodate cutting tool sizes of different diameters, further enhancing the device's flexibility.

[0013] Furthermore, in the aforementioned assembleable and detachable portable knife adjuster device, the detection rod includes a core rod and a detection block, with the detection block connected to one end of the core rod. The sleeve includes a tube and a connecting part, which are integrally connected. The tube has a third through hole along its axis, and the connecting part has a mounting hole. The axis of the mounting hole and the axis of the third through hole are set at an angle, and the mounting hole and the third through hole communicate with each other. A dial indicator is installed in the mounting hole, and the core rod is slidably connected in the third through hole. The dial indicator installed in the mounting hole abuts against the core rod.

[0014] The detection block is made of wear-resistant material, and the end furthest from the connection part is semi-circular to reduce wear, decrease the contact area with the tool, and reduce detection errors. The inner surface of the third through hole and the outer surface of the core rod both have high smoothness and high fit, reducing detection errors caused by friction.

[0015] Furthermore, in the aforementioned assembleable and detachable portable tool adjuster device, there are two or more measuring mechanisms. Multiple measuring structures can simultaneously detect the radial runout of the tool at different positions.

[0016] Furthermore, in the aforementioned assembleable and detachable portable tool adjuster device, the column is connected to a guide rail, which is vertically positioned. The support arm is slidably connected to the guide rail, and the support arm has a threaded hole in which a locking bolt passes. The guide rail allows the support arm to slide along it, ensuring stable movement. The locking bolt secures the support arm to a suitable height on the guide rail. The measuring support plate is also slidably connected to the guide rail and locked in place by the locking bolt.

[0017] As can be seen from the above technical solution, this utility model has the following beneficial effects: This utility model is a portable tool adjuster device that can be assembled and disassembled. By pulling the lever to fix the tool, it improves the convenience of installing and disassembling the tool, shortens the testing time, and improves tool adjustment efficiency and production efficiency. At the same time, this utility model sets the entire device into three parts: a base, a first base platform, and a second base platform. The first and second base platforms can be detached from the base, facilitating storage and transportation and improving the convenience of the device. The radial runout of the tool is transmitted to the dial indicator through the detection rod, reducing wear and increasing service life. Attached Figure Description

[0026] Example 1

[0027] like Figure 1-2 The illustrated portable tool adjuster includes a base 1. A first base platform 2 and a second base platform 3 are detachably connected to the top surface of the base 1 via fasteners. A column 4 is connected to the top surface of the first base platform 2. A first positioning mechanism 5 and a measuring mechanism 7 are connected to the column 4. A second positioning mechanism 6 is connected to the top surface of the second base platform 3. The first positioning mechanism 5 and the second positioning mechanism 6 are arranged opposite to each other, and the measuring mechanism 7 is located between the first positioning mechanism 5 and the second positioning mechanism 6. The first positioning mechanism 5 is connected to the column 4 via a support arm 51. A first through hole 50 is provided at the end of the support arm 51 away from the column 4. The first positioning mechanism 5 is connected to the first through hole 50. A pull rod 52 is connected to the upper end of the first positioning mechanism 5. The pull rod 52 pulls the first positioning mechanism 5, causing the first positioning mechanism 5 to move along the first through hole 50.

[0028] In this embodiment, an upper positioning block 501 and a lower positioning block 502 are respectively provided on the upper and lower sides of the first through hole 50. The upper positioning block 501 and the lower positioning block 502 are each provided with a through hole, and the through holes of the upper positioning block 501 and the lower positioning block 502 are coaxially arranged in the first through hole 50. The first positioning mechanism 5 includes a first center 53, a shaft portion 54, and a pull stud 55. The shaft portion 54 is connected to the first center 53, and the end of the shaft portion 54 away from the first center 53 is threadedly connected to the pull stud 55. The head of the pull stud 55 is located in the countersunk through hole of the upper positioning block 501. A spring is sleeved on the pull stud 55, and the two ends of the spring abut against the grooves provided at the top of the shaft portion 54 and the bottom of the upper positioning block 501, respectively.

[0029] like Figure 2-3 The portable knife adjuster device shown is assembleable and detachable. The upper positioning block 501 is provided with a rocker slot 5011, and a rocker block 503 is hinged in the rocker slot 5011. The rocker part 5031 of the rocker block 503 is located on the lower side of the head of the pull stud 55. A pull rod 52 is connected to the end of the rocker block 503 away from the pull stud 55. The pull rod 52 is set at an angle.

[0030] like Figure 4 The assembleable and detachable portable tool adjuster device shown has a shaft portion 54 with a first guide groove 541, which is axially arranged along the shaft portion 54. The lower positioning block 502 has a first threaded through hole 5021, which is radially arranged along the shaft portion 54. A set screw is internally threaded into the first threaded through hole 5021, extending into the first guide groove 541. During the upward or downward movement of the shaft portion 54, the set screw moves along the first guide groove 541, restricting the rotation of the shaft portion 54 and ensuring the straightness and stability of the movement of the first tip 53.

[0031] like Figure 5 The portable tool adjuster device shown is assembleable and detachable. The second positioning mechanism 6 includes a second center 61 and a bushing 62. The bushing 62 is connected to the outside of the second center 61, and its upper end has an external thread. An adjusting ring 63 is threadedly connected to the upper end of the bushing 62. The second base 3 has a second through hole 31, which is vertically arranged. The bushing 62 is slidably connected within the second through hole 31. A thrust bearing 64 is located in a groove at the top of the second base 3, positioned between the adjusting ring 63 and the second base 3. A second guide groove 621 is vertically arranged on the outer wall of the bushing 62. The second base 3 has a second threaded through hole 32, which is threadedly connected to a set screw that extends into the second guide groove 621.

[0032] When the tool is installed between the first positioning mechanism 5 and the second positioning mechanism 6, the rotating adjusting ring 63 restricts the bushing 62 from rotating due to the set screw extending into the second guide groove 621. The bushing 62 does not rotate. The adjusting ring 63 drives the bushing 62 to rise or fall relative to the adjusting ring 63, thereby driving the second center 61 to rise or fall, adapting to tools of different lengths, adjusting the preload, or meeting the testing requirements.

[0033] like Figure 6 The portable tool adjuster device shown is assembleable and detachable. The measuring mechanism 7 includes a measuring support plate 71, a detection rod 72, and a sleeve 73. The measuring support plate 71 and the column 4 are slidably connected, and the measuring support plate 71 is threaded with a locking screw. The measuring support plate 71 and the sleeve 73 are connected. The detection rod 72 is slidably connected within a through hole in the sleeve 73. A dial indicator is connected to the sleeve 73, and the detection rod 72 and the dial indicator connected to the sleeve 73 abut against each other. During measurement, the detection rod 72 transmits the detected radial runout of the tool to the dial indicator connected to the sleeve 73.

[0034] In this embodiment, the detection rod 72 includes a core rod 721 and a detection block 722, with the detection block 722 connected to one end of the core rod 721. The sleeve 73 includes a tube portion 731 and a connecting portion 732, which are integrally connected. The tube portion 731 has a third through hole 7311 along its axis, and the connecting portion 732 has a mounting hole 7321. The axis of the mounting hole 7321 and the axis of the third through hole 7311 are angled, and the mounting hole 7321 communicates with the third through hole 7311. A dial indicator is installed in the mounting hole 7321, and the core rod 721 is slidably connected within the third through hole 7311. The dial indicator installed in the mounting hole 7321 abuts against the core rod 721. The detection block is made of a wear-resistant material, and the end furthest from the connecting portion 732 has a semi-circular shape to reduce wear, decrease the contact area with the cutting tool, and reduce detection errors. The inner surface of the third through hole 7311 and the outer surface of the core rod 721 both have high smoothness and high fit, reducing detection errors caused by friction.

[0035] In this embodiment, there are two or more measuring mechanisms 7. To avoid interference between dial indicators after setting multiple measuring mechanisms 7, the mounting holes 7321 should be arranged opposite each other or in parallel.

[0036] In this embodiment, the column 4 is connected to a guide rail 41, which is vertically arranged. The support arm 51 is slidably connected to the guide rail 41. The support arm 51 has a threaded hole 511, and a locking bolt passes through the threaded hole 511. The guide rail 41 is set so that the support arm 51 can slide along the guide rail 41, ensuring movement stability. The locking bolt can fix the support arm 51 at a suitable height on the guide rail 41. The axes of the first tip 53 and the second tip 61 are arranged in a straight line, which is parallel to the guide rail 41.

[0037] Taking the detection of the radial runout of the tool as an example, place the tool on the upper side of the second center point 61 provided in the second positioning mechanism 6. The second center point 61 extends into the center positioning hole of the tool. Press down the pull rod 52. The pull rod 52 drives the toggle 503 to rotate. The rotation of the toggle 503 causes the lifting part 5031 to move upward. The lifting part 5031 pushes the pull stud 55 upward. The pull stud 55 drives the shaft part 54 and the first center point 53 to lift, and the spring is compressed. Move the upper end of the tool to the lower side of the first center point 53. Slowly release the pull rod 52. The pull rod 52 moves upward. The spring resets. The spring pushes the first center point 53 downward. The first center point 53 extends into the center positioning hole at the upper end of the tool, and the tool is positioned and fixed between the first center point 53 and the second center point 61. At this time, the tool can rotate around the tool axis. Rotate the adjusting ring 63 clockwise. The bushing 62 is restricted by the setscrew extending into the second guide groove 621 and does not rotate. The adjusting ring 63 drives the bushing 62 to rise. The bushing 62 drives the second center point 61 to rise to adjust the tool pre-tightening force.

[0038] Insert the dial indicator into the mounting hole 7321 and fix the dial indicator using the side-top bolt. The core rod 721 is slidably connected in the third through hole 7311, and the core rod 721 abuts against the measuring head of the dial indicator. Loosen the side-top screw that fixes the measuring support plate 71 and the guide rail 41. Slide the measuring support plate 71 along the guide rail 41 to the position where the tool is to be measured. Loosen the side-top screw that fixes the pipe part 731 and the measuring support plate 71. Adjust the extending length of the pipe part 731 so that the detection block 722 abuts against the cutting edge of the tool. Rotate the tool. The detection block 722 is displaced by the push of the tool. The detection block 7232 pushes the core rod 721 to move along the third through hole 7311. The dial indicator detects the displacement of the core rod 721 and displays the value through the dial. When the values of each edge of the tool detected by the dial indicator are the same, it is qualified; otherwise, it is unqualified. When disassembling the tool, press down the pull rod 52 to drive the first center point 53 to lift, and remove the tool. The measurement is completed.

[0039] The above embodiments are exemplary. Their purpose is to illustrate the technical concept and features of the present invention so that those skilled in this field can understand the content of the present invention and implement it accordingly. It should not be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
