Description

Technical Field

[0001] This utility model relates to the field of machining tooling technology, and in particular to a five-axis machining tooling for an inducer wheel. Background Technology

[0002] An inducer is an axial flow impeller, usually installed upstream of the first-stage impeller of a centrifugal pump and rotating synchronously with the impeller. Its main function is to reduce the net positive suction pressure of the centrifugal pump by increasing the static pressure at the inlet of the first-stage impeller.

[0003] Triangular chucks are commonly used to clamp the idler wheel in the machining of the idler wheel. However, the clamping blocks of existing triangular chucks are exposed. Metal chips generated during workpiece machining will enter the internal structure of the triangular chuck, interfering with the operation of the triangular chuck. Furthermore, the metal chips that accumulate in the inner ring of the triangular chuck are not easy to clean.

[0004] Therefore, to address the above issues, a five-axis machining fixture for the inducer wheel can be designed to improve the triangular chuck by moving the clamping blocks inside the chuck, thus preventing metal debris from affecting the operation of the chuck. Utility Model Content

[0005] In order to overcome the problem that most of the machining of the inducer wheel uses a triangular chuck to hold the inducer wheel, but the existing triangular chuck has exposed clamping blocks, and metal chips generated during workpiece machining will enter the internal structure of the triangular chuck, interfering with the operation of the triangular chuck, and the metal chips are difficult to clean when they accumulate in the inner ring of the triangular chuck.

[0006] The technical solution of this utility model is as follows: a five-axis machining fixture for an inducer wheel, including a base, a top cover, a connecting threaded component, a transmission slider, a sliding clamp, a transmission gear ring, a guide seat, a threaded rod, and a force-bearing block; the top cover is provided above the base, and the top cover and the base together form an outer shell. The connecting threaded component is provided on the inner side of the outer shell. Three sets of transmission sliders are provided above the base. A sliding clamp is provided above the transmission slider. A transmission gear ring is provided on one side of the transmission slider. A guide seat is provided on the inner side of two sets of transmission sliders. A threaded rod is provided on the inner side of one set of transmission sliders. A force-bearing block is provided at one end of the threaded rod.

[0007] Preferably, the base and the top cover are assembled into a closed shell by setting connecting threaded parts to prevent metal debris from entering the device. The force block receives external power to drive the threaded rod to rotate, causing a set of transmission sliders to move. The transmission gear ring drives two other sets of transmission sliders to move, causing the sliding clamp to hold the workpiece. The guide seat guides the sliding of the transmission sliders to achieve the blocking of metal debris.

[0008] Preferably, the base has multiple sets of fixing holes arranged in a circle on its bottom, and three sets of cleaning grooves on its bottom.

[0009] Preferably, the upper outer ring and inner ring of the base are provided with a first connecting ring, which is convex on the outside and concave on the inside. The upper part of the base is provided with three sets of first connecting holes, which are circular at the top and regular hexagonal at the bottom.

[0010] Preferably, a second connecting hole is provided on the top of the cover. The second connecting hole is two circular segments, with the diameter of the upper circular segment being larger than that of the bottom circular segment. A second connecting ring is provided on the inner and outer rings at the bottom of the cover. The second connecting ring is concave on the outside and convex on the inside.

[0011] Preferably, the inner side of the top cover is provided with three sets of sliding seats, which pass through the inner ring of the top cover, and guide strips are provided on both sides of the inner side of the sliding seats.

[0012] Preferably, the upper part of the transmission slider is provided with helical teeth, and the bottom of the sliding clamp is also provided with helical teeth. The two sets of helical teeth can mesh with each other. The sliding clamp is located inside the sliding seat, and guide grooves are provided on both sides of the sliding clamp. The guide grooves fit together with each other.

[0013] Preferably, the inner side of the transmission slider is provided with a through hole. The through hole of one set of transmission sliders is a threaded hole. The two sets of transmission sliders are slidably connected to the guide seat through ordinary through holes. One set of transmission sliders is threadedly connected to the threaded rod through a threaded through hole.

[0014] Preferably, a rack is provided on the inner side of the transmission slider, and the rack meshes with the transmission gear ring. Multiple sets of transmission sliders are arranged around the circumference of the transmission gear ring.

[0015] The beneficial effects of this utility model are as follows: During workpiece processing, the first connecting ring and the second connecting ring are interlocked, and the base and the top cover are connected and fixed by inserting the connecting threaded parts into the first connecting hole and the second connecting hole, so that the base and the top cover are assembled into a sealed shell. The metal chips generated during processing are difficult to enter the device and affect the operation of the structure. At the same time, the cleaning groove at the bottom of the base makes it easy to use an air gun to blow out the metal chips accumulated in the inner ring of the device, thereby blocking the metal chips and facilitating the long-term normal operation of the tooling, thus enhancing the practical value of the device.

[0024] Please see Figure 2 In this embodiment, the bottom of the base 1 has multiple sets of fixing holes 101 arranged in a circle. The bottom of the base 1 has three sets of cleaning grooves 102. The upper outer ring and inner ring of the base 1 are provided with first connecting rings 104, which are convex on the outside and concave on the inside. The upper part of the base 1 has three sets of first connecting holes 103, which are circular at the top and regular hexagonal at the bottom. The tooling is connected and fixed to the five-axis machining center through the fixing holes 101. The cleaning grooves 102 are used to clean the metal debris on the inner ring of the tooling. The first connecting rings 104 are used to facilitate the docking and splicing of the base 1 and the upper cover 2. The first connecting holes 103 are used to accommodate the connecting threaded parts 3.

[0025] Please see Figure 3In this embodiment, a second connecting hole 201 is provided on the upper part of the cover 2. The second connecting hole 201 is two circular segments, with the diameter of the upper circular segment being larger than that of the bottom circular segment. A second connecting ring 204 is provided on the inner and outer rings at the bottom of the cover 2. The second connecting ring 204 is concave on the outside and convex on the inside. Three sets of sliding seats 202 are provided on the inner side of the cover 2. The sliding seats 202 penetrate the inner ring of the cover 2. Guide strips 203 are provided on both sides of the inner side of the sliding seats 202. The connecting threaded part 3 is accommodated through the second connecting hole 201. The sliding clamp 5 is accommodated by the sliding seat 202. The sliding clamp 5 is guided to slide by the guide strips 203. The second connecting ring 204 facilitates the docking and splicing of the base 1 and the cover 2.

[0026] Please see Figure 4 In this embodiment, a helical tooth 403 is provided on the upper part of the transmission slider 4, and a helical tooth 403 is also provided on the bottom of the sliding clamp 5. The two sets of helical teeth 403 can mesh with each other. The sliding clamp 5 is located inside the sliding seat 202. Guide grooves 501 are provided on both sides of the sliding clamp 5. The guide grooves 501 are interlocked with each other. A through hole 401 is provided on the inner side of the transmission slider 4. The through hole 401 of one set of transmission sliders 4 is a threaded hole. The two sets of transmission sliders 4 are slidably connected to the guide seat 7 through ordinary through holes 401. One set of transmission sliders 4 is connected to the guide seat 7 through threaded holes. The through hole 401 is threadedly connected to the threaded rod 8. A rack 402 is provided on the inner side of the transmission slider 4. The rack 402 meshes with the transmission gear ring 6. Multiple sets of transmission sliders 4 are arranged around the circumference of the transmission gear ring 6. The through hole 401 is used to make the transmission slider 4 slide to the guide seat 7. The rack 402 drives the transmission gear ring 6 to rotate synchronously with the movement of the three sets of transmission sliders 4. The helical teeth 403 drive the sliding clamp 5 to move and clamp the workpiece. The guide groove 501 and the guide bar 203 are used to make the sliding clamp 5 slide to the sliding seat 202 and guide the sliding.

[0027] When clamping the workpiece, the pressure rod is inserted into the force block 9 and rotated, causing the threaded rod 8 to rotate and drive the transmission slider 4 to move through the threaded connection with a set of transmission sliders 4. The moving transmission slider 4 drives the transmission gear ring 6 through the rack 402 to drive the other two sets of transmission sliders 4 to slide synchronously. The guide seat 7 is slidably connected to the other two sets of transmission sliders 4 through the through hole 401 to guide the sliding of the transmission slider 4. The sliding transmission slider 4 drives the sliding clamp 5 in the sliding seat 202 to move towards the inner ring of the device through the helical teeth 403 to clamp and fix the workpiece. The mutual engagement of the guide bar 203 and the guide groove 501 makes the sliding clamp 5 slidably connected to the sliding seat 202 and guides the sliding.

[0028] During workpiece processing, the first connecting ring 104 and the second connecting ring 204 are interlocked, and the connecting threaded part 3 is inserted into the first connecting hole 103 and the second connecting hole 201 to connect and fix the base 1 and the top cover 2, so that the base 1 and the top cover 2 are assembled into a sealed shell. The metal chips generated during processing are difficult to enter the device and affect the operation of the structure. At the same time, the cleaning groove 102 at the bottom of the base 1 makes it easy to use an air gun to blow out the metal chips accumulated in the inner ring of the device.

[0029] Through the above steps, the base 1 and the top cover 2 are assembled into a closed shell by setting the connecting threaded part 3, which prevents metal debris from entering the device. The force block 9 receives external power to drive the threaded rod 8 to rotate, causing a set of transmission sliders 4 to move. The transmission gear ring 6 drives the other two sets of transmission sliders 4 to move, which in turn drives the sliding clamp 5 to clamp the workpiece. The guide seat 7 guides the sliding of the transmission sliders 4, thereby blocking metal debris, facilitating the long-term normal operation of the tooling, and enhancing the practical value of the device.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
