Description

Technical Field

[0001] This invention relates to the field of oil pump processing technology, specifically a machining center tooling fixture for machining fuel injection pump bodies. Background Technology

[0002] As a core component of the diesel engine fuel system, the fuel injection pump body's machining accuracy directly affects the engine's fuel supply stability, combustion efficiency, and emission performance. During production, the die-cast blank of the fuel injection pump body needs to be precision machined through a machining center. After precision machining, it is convenient for subsequent assembly. When the pump body blank is processed in the machining center, it needs to be clamped by a specified tooling to facilitate loading and unloading operations and achieve precise machining of the parts.

[0003] However, when clamping pump bodies, traditional tooling is mostly customized for a single model of pump body, with fixed positions for the vertical plate, pressure plate and positioning block. It is difficult to adapt to the clamping requirements of pump bodies of different specifications and sizes. When switching products, it is often necessary to disassemble and readjust the fixture or replace the entire set of tooling, resulting in long downtime and seriously affecting the production cycle. Meanwhile, the lack of chip sorting and collection components on the clamping fixture means that metal chips and coolant generated during processing can easily scatter onto the machine tool's worktable, making cleaning difficult. This not only pollutes the working environment, but the accumulated chips can also scratch the machined surface or enter the machine tool's interior, causing wear on the slider and guide rails and affecting the equipment's accuracy. Summary of the Invention

The side plates at both ends of the two horizontal plates are detachably connected to the opposite sides of the two turntables via fasteners. Support blocks are detachably installed at the bottom of each of the two mounting bases.

[0012] Specifically, each of the two mounting bases has a control mechanism for driving and controlling the turntable installed inside.

Each of the two fixing plates has a detachable locking block installed on its top. Each of the bottom ends of the two horizontal plates has a locking groove. The two locking blocks are slidably connected to the two sets of locking grooves.

[0014] Specifically, the cross-section of the card block and the card slot are both "T" shaped structures, and the length of the card block is greater than the width between the two horizontal plates.

[0015] Specifically, the card block is equipped with a locking mechanism for limiting the position of the collection box after installation. The locking mechanism includes a protrusion.

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] like Figure 4 and Figure 5 As shown, the present invention provides a machining center fixture for machining an injection pump body, comprising a mounting mechanism 1 for placing the part, a clamping mechanism 2 for stabilizing the part on the mounting mechanism 1, and a collection mechanism 5 for collecting and storing debris at the bottom of the mounting mechanism 1.

[0025] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, the mounting mechanism 1 includes two parallel horizontal plates 101, with side plates 102 welded to both ends of the two horizontal plates 101 respectively. A vertical plate 103 is installed between the tops of the two horizontal plates 101. The installation of the two horizontal plates 101 facilitates the connection of the two side plates 102, and the installation of the vertical plate 103 facilitates the division of the two ends of the horizontal plates 101, thereby enabling the placement and processing of two parts.

[0026] Specifically, such as Figure 4As shown, the two horizontal plates 101 are provided with multiple equally spaced fixing holes 105. The bottom ends of the vertical plate 103 are detachably connected to the top of the two horizontal plates 101 by fasteners that fit the fixing holes 105. The vertical plate 103 has a trapezoidal structure. Multiple equally spaced reinforcing ribs 104 are welded between the two horizontal plates 101. The multiple fixing holes 105 facilitate the lateral adjustment of the position of the vertical plate 103, making it suitable for installing parts of different sizes. At the same time, the trapezoidal structure design of the vertical plate 103 increases its stability. The installation of multiple reinforcing ribs 104 ensures a firm connection between the two horizontal plates 101, preventing deformation and ensuring stability during part processing without affecting the processing accuracy.

[0027] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, the clamping mechanism 2 includes cylinders 201. One side plate 102 and the upright plate 103 are detachably mounted with cylinders 201 on the same side, and the other side plate 102 and the upright plate 103 are detachably mounted with irregularly shaped rubber blocks 202 on the same side. Rubber sleeves 203 are installed on the output shafts of the two cylinders 201 respectively. By installing the two cylinders 201 and cooperating with the two irregularly shaped rubber blocks 202, two parts can be clamped. The side of the two rubber blocks 202 closest to the parts matches the outer shape of the parts, so that the parts are clamped stably between the cylinders 201 and the rubber blocks 202 without loosening. The installation of the rubber sleeves 203 helps to prevent wear when clamping the parts. The detachable installation of the cylinders 201 and the rubber blocks 202 with the side plate 102 and the upright plate 103 facilitates disassembly and replacement, realizing the clamping of parts of different models.

[0028] Specifically, such as Figure 1 , Figure 3 and Figure 5 As shown, the collection mechanism 5 includes a collection box 501. The collection box 501 is provided at the bottom of the two horizontal plates 101. The width of the collection box 501 is greater than the width between the two horizontal plates 101. The installation of the collection box 501 facilitates the recycling and storage of debris and coolant that fall during the processing of parts, reducing the pollution of the work surface.

[0029] Specifically, such as Figure 5 As shown, handles 504 are installed on both sides of the collection box 501. A drain pipe 502 is connected to the center of the bottom of the collection box 501. A filter screen 503 is snapped into the inner side of the bottom of the collection box 501. The installation of the two handles 504 facilitates the handling of the collection box 501 during disassembly and assembly, enabling the collection box 501 to be removed for cleaning. The installation of the filter screen 503 facilitates the separation of debris and cooling water. With the cooperation of the drain pipe 502, the filtered cooling water can be discharged and recycled, while reducing the weight of the collection box 501 and making it easier for subsequent disassembly and cleaning.

[0030] Specifically, such as Figure 1 and Figure 2 As shown, each of the two horizontal plates 101 has a rotating mechanism 3 at both ends for adjusting the angle of the parts. The rotating mechanism 3 includes a mounting base 301. Each of the two horizontal plates 101 has a symmetrical mounting base 301 at both ends. The two symmetrical mounting bases 301 are rotatably connected to a turntable 302 on opposite sides via a rotating shaft 303. The side plates 102 at both ends of the two horizontal plates 101 are detachably connected to the opposite sides of the two turntables 302 via fasteners. Support blocks 304 are detachably mounted on the bottom of each of the two mounting bases 301. The cooperation of the two support blocks 304 facilitates the detachable installation of the two symmetrical mounting bases 301 and the worktable. The cooperation of the two turntables 302 facilitates the connection of the side plates 102 at both ends of the two horizontal plates 101, so that the two mounting bases 301 support the two horizontal plates 101. At the same time, the cooperation of the rotating shaft 303 enables the two side plates 102 to rotate with the two turntables 302 and the two mounting bases 301, thereby allowing the parts on the horizontal plates 101 to adjust their direction and achieve processing at different angles.

[0031] Specifically, such as Figure 2 As shown, each of the two mounting bases 301 houses a control mechanism 4 for driving and controlling the turntable 302. The control mechanism 4 includes a first gear 401, which is rotatably connected to each of the two mounting bases 301. The first gear 401 is fixedly connected to the center of the rotating shaft 303. A second gear 403 is also rotatably connected to each of the two mounting bases 301, meshing with the first gear 401. A servo motor 402 is detachably mounted inside each of the two mounting bases 301. The output shaft of the servo motor 402 is connected to the second gear 403. The first gear 401... The diameter of the first gear 401 is larger than that of the second gear 403. Through the installation of the servo motor 402, under the control of the external driver, the servo motor 402 can be precisely controlled. The servo motor 402 drives the second gear 403 to rotate the first gear 401, thereby enabling the rotating shaft 303 to drive the turntable 302 to rotate, thereby adjusting the angle of the parts on the horizontal plate 101 and realizing the processing of the parts at different angles. The different diameters of the first gear 401 and the second gear 403 increase the torque. Furthermore, the design according to a certain ratio enables the servo motor 402 to precisely control the angle of the parts, thereby increasing the processing accuracy.

[0032] Specifically, such as Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, a disassembly and assembly mechanism 6 is installed between the bottom of the horizontal plate 101 and the collection box 501 for disassembling and cleaning the collection box 501. The disassembly and assembly mechanism 6 includes a fixing plate 601. The top of each end of the collection box 501 is welded with a fixing plate 601. The top of each fixing plate 601 is detachably equipped with a locking block 603. The bottom of each end of the two horizontal plates 101 is provided with a locking groove 602. The two locking blocks 603 are slidably connected to the two sets of locking grooves 602. The collection box 501 is detachably slidably connected to the bottom of the horizontal plate 101 through the locking blocks 603 and the locking grooves 602. The installation of the two fixing plates 601 and the collection box 501 facilitates the connection of the two locking blocks 603. The opening of the two locking grooves 602 facilitates the detachable slidable connection of the two locking blocks 603 to the bottom of the horizontal plate 101, making it easy to disassemble and clean the collection box 501 and the bottom of the horizontal plate 101, which is convenient to operate.

[0033] Specifically, such as Figure 3 , Figure 6 and Figure 8 As shown, both the locking block 603 and the slot 602 have a "T" shaped cross-section. The length of the locking block 603 is greater than the width between the two horizontal plates 101. The "T" shaped design of the locking block 603 and the slot 602 facilitates the locking block 603 from falling off the slot 602 after sliding and engaging with it, thus playing a longitudinal limiting role and achieving stable installation between the two locking blocks 603 and the two horizontal plates 101.

[0034] Specifically, such as Figure 6 , Figure 7 and Figure 8 As shown, a locking mechanism 7 is installed on the locking block 603 to limit the movement of the collection box 501 after installation. The locking mechanism 7 includes a protrusion 701. The tops of the two locking blocks 603 are respectively equipped with protrusions 701. The bottom of the protrusion 701 slides elastically with the inside of the locking block 603 through a contact spring 702. The inside of the multiple slots 602 is provided with grooves 703 corresponding to the protrusions 701. The top of the protrusion 701 and the grooves 703 are both hemispherical structures. The top of the protrusion 701 abuts against the inside of the groove 703. Through the cooperation of the contact spring 702, the protrusion 701 and the locking block 603 can slide elastically. The locking block 603 is inserted into the slot 603. When the protrusion 701 is inside the groove 602, because the top of the protrusion 701 is a spherical structure, the protrusion 701 is pressed against the edge of the groove 602 and the spring 702 is compressed and contracted, so that the block 603 can slide smoothly into the groove 602. After the block 603 slides to the designated position, the top of the protrusion 701 is aligned with the groove 703. Under the pressure of the spring 702, the protrusion 701 slides upward and inserts into the groove 703, thus positioning the block 603. The block 603 and the groove 602 are stably engaged and not easy to loosen. By pulling the block 603 with a certain pulling force, the protrusion 701 will be compressed and contracted by the inner wall of the groove 703, so that the block 603 can slide out.

[0035] In use, the two mounting bases 301 are first detachably mounted to the machining center table via two support blocks 304. Then, the two turntables 302 facilitate the connection of the side plates 102 at both ends of the two horizontal plates 101, enabling the two mounting bases 301 to support the two horizontal plates 101. Simultaneously, the rotating shaft 303 allows the two side plates 102 to rotate with the two turntables 302 and the two mounting bases 301, thereby allowing the orientation of parts on the horizontal plates 101 to be adjusted for machining at different angles. Through the installation of the servo motor 402, precise control of the servo motor 402 is achieved under the control of an external driver. The servo motor 402 drives the second gear 403 to rotate the first gear 401, thus achieving rotation... Shaft 303 drives turntable 302 to rotate, enabling the adjustment of the angle of parts on horizontal plate 101 and allowing for machining at different angles. The first gear 401 and the second gear 403 have different diameters, increasing torque. Designed in a specific ratio, the servo motor 402 can precisely control the angle of the parts, increasing machining accuracy. The installation of two horizontal plates 101 facilitates the connection of two side plates 102. The installation of vertical plate 103 facilitates the division of the two ends of the horizontal plate 101, allowing for the placement and machining of two parts. Multiple fixing holes 105 facilitate the lateral adjustment of the vertical plate 103, suitable for mounting parts of different sizes. Furthermore, the trapezoidal structure design of the vertical plate 103 increases its stability. The installation of multiple reinforcing ribs 104 ensures a firm connection between the two horizontal plates 101, preventing deformation and ensuring stability during part processing without affecting machining accuracy. The installation of two cylinders 201, in conjunction with two irregularly shaped rubber blocks 202, clamps the two parts. The shape of the rubber blocks 202 matching the outer side of the parts ensures stable clamping between the cylinders 201 and the rubber blocks 202, preventing loosening. The installation of rubber sleeves 203 reduces wear during part clamping. The detachable installation of cylinders 201 and rubber blocks 202 with the side plates 102 and vertical plates 103 facilitates disassembly and replacement, enabling clamping of different part models. The installation of the collection box 501 facilitates part processing. The system collects and stores fallen debris and coolant, reducing contamination of the work surface. Two handles 504 facilitate easy handling during disassembly and assembly of the collection box 501, allowing for easy removal and cleaning. A filter screen 503 separates debris and coolant, and with the help of a drain pipe 502, the filtered coolant is discharged and recycled, reducing the weight of the collection box 501 and facilitating subsequent disassembly and cleaning. Two fixing plates 601 are installed with the collection box 501, facilitating the connection of two locking blocks 603. Two slots 602 allow for a detachable sliding connection between the two locking blocks 603 and the bottom of the horizontal plate 101, enabling easy disassembly and cleaning of the collection box 501 and the bottom of the horizontal plate 101. The system is easy to operate.The "T"-shaped design of the locking block 603 and the slot 602 ensures that after the locking block 603 and the slot 602 slide and engage, the locking block 603 will not fall off, thus providing a longitudinal limiting function and ensuring stable installation between the two locking blocks 603 and the two horizontal plates 101. The engagement of the contact spring 702 allows the protrusion 701 to slide elastically with the locking block 603. When the locking block 603 is inserted into the slot 602, the protrusion 701, with its spherical top, is abutted by the edge of the slot 602. The subsequent compression of the contact spring 702 allows the locking block 603 to smoothly slide into the slot 602. Once the locking block 603 reaches the designated position, the top of the protrusion 701 aligns with the groove 703. Under the pressure of the contact spring 702, the protrusion 701 slides upwards and inserts into the groove 703, thus positioning the locking block 603. The locking block 603 and slot 602 are stably engaged and not easily loosened. By applying a certain pulling force to the locking block 603, the protrusion 701 is compressed and contracted by the inner wall of the groove 703, allowing the locking block 603 to slide out.
