Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and more specifically, to a highly adaptable milling tooling and fixture. Background Technology

[0002] In existing small-scale milling operations of pump bodies, fixtures are required to hold the pump body in place so that the milling cutter can cut it. Traditional pump body fixtures are typically designed for a single pump type, meaning a custom fixture is made for each type of pump body to hold it in place and complete the milling operation. When processing a different type or specification of pump body, the machine must be stopped, the original fixture removed, and a new fixture installed and adjusted. This results in high fixture setup and production costs, low fixture utilization, and long production preparation and speed adjustment intervals, making it difficult to meet the production demands of high-speed milling. Furthermore, for small-batch, multi-variety production orders, a dedicated fixture needs to be designed for each type of pump, leading to extremely high design, casting material, machining, and management costs. Therefore, a highly adaptable milling tooling fixture is proposed. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address at least one of the aforementioned problems, this utility model first provides a highly adaptable milling fixture with adjustable components connected on a set of fixtures. This fixture is adapted to fix and limit pump bodies of different widths, heights, and thicknesses, thereby improving the adaptability of the fixture.

[0005] (II) Technical Solution

[0006] To solve the aforementioned technical problem, this utility model provides a highly adaptable milling fixture suitable for use in milling positioning on a milling machine. It includes a fixture base and an adjustment assembly. The adjustment assembly includes multiple sets of tilt adjustment columns. The fixture base has several first inclined slots evenly distributed within its body. A connecting limit frame is provided at the lower end of the fixture base. The connecting limit frame has second inclined slots aligned with the first inclined slots. During installation, the tilt adjustment columns are inserted from the second inclined slots into the first inclined slots and then extend outwards. Each tilt adjustment column has a connecting frame, and each connecting frame has an adjusting screw. When using the fixture base, a pump body abutment column is placed on the adjusting screw to abut against the pump body to be milled.

[0007] Furthermore, the connecting limiting frame is welded to the clamp base, and the first inclined slot is connected to the second inclined slot.

[0008] Furthermore, the inner wall of the first inclined slot is configured as a first grinding panel, the inner wall of the second inclined slot is configured as a second grinding panel, and the side panel of the tilt adjustment column is configured as a third grinding panel.

[0009] Furthermore, a setting panel is provided at the center of the upper end face of the clamp base. The setting panel is set below the edge of the clamp base. The upper end face of the tilt adjustment column is parallel to the setting panel, and the lower end face of the tilt adjustment column is parallel to the upper end face of the tilt adjustment column.

[0010] Furthermore, each set of tilt adjustment columns is provided with several adjustment through holes, which are parallel to each other along the direction of the tilt adjustment column, and the spacing between adjacent adjustment through holes is the same.

[0011] Furthermore, the connecting limiting frame is provided with independent first slots and second slots at each of the tilt adjustment columns. When the tilt adjustment column is in place, the first slot is provided with a first positioning pin, which is inserted into a set of adjustment through holes of the tilt adjustment column. The second slot is provided with a second positioning pin, which is inserted into the next set of adjustment through holes of the tilt adjustment column.

[0012] Furthermore, the fixture base has a central slot in the center, a central adjusting post in the central slot, and a plurality of connecting sockets evenly arranged on the side of the central adjusting post, the spacing of the connecting sockets being the same as the spacing between the adjusting through holes.

[0013] Furthermore, the central adjusting column is provided with a first abutment, a second abutment, or a third abutment. The first abutment has one alignment hole corresponding to the connection port, the second abutment has two alignment holes corresponding to the connection port, and the third abutment has three alignment holes corresponding to the connection port.

[0014] Furthermore, the upper end of the tilt adjustment column is provided with a set of welding grooves, and the bottom of the connecting frame is provided with welding columns, which are welded to the welding grooves.

[0015] Furthermore, both the clamp base and the connecting limit frame are solid structures, and the clamp base, the connecting limit frame, and the tilt adjustment column are made of the same material.

[0016] (III) Beneficial Effects

[0017] This utility model provides a highly adaptable milling fixture, which features multiple sets of tilt adjustment columns on the fixture base to achieve multi-point limiting and abutment of the pump body. The point-to-point abutment reduces the impact and wear caused by single-point abutment force on the fixture and pump body. By cooperating with the connecting limit frame to change the specific extension position of the tilt adjustment columns, the specific spacing of each connecting frame on the abutment plane can be changed to adapt to pump bodies of different diameters and lengths. The width of the pump body abutment column on the adjusting screw can be adjusted according to requirements, further adapting to clamping pump bodies of different diameters and lengths. This solution features abutment seats with different widths for alignment adjustment, adjusted according to the extension of the tilt adjustment column and the thickness of the pump body edge, to achieve abutment processing for pump bodies of different thicknesses. This solution is adaptable to abutment and limiting use for multiple sets of pump bodies of different lengths, widths, and thicknesses within a certain range, differing from the traditional "one tool, one use" model and improving the adaptability of the fixture.

Detailed Implementation

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0031] See Figures 1 to 10 This utility model provides a highly adaptable milling fixture suitable for use with a milling machine for milling positioning. It includes a fixture base 1 and an adjustment assembly. The adjustment assembly includes multiple sets of tilt adjustment columns 5. The fixture base 1 has a plurality of first inclined slots 102 evenly distributed within its body. A connecting limit frame 9 is provided at the lower end of the fixture base 1. The connecting limit frame 9 has second inclined slots 903 respectively aligned with the first inclined slots 102. During installation, the tilt adjustment columns 5 are inserted from the second inclined slots 903 into the first inclined slots 102. 2. Extend outwards; each of the inclined adjustment columns 5 is provided with a set of connecting frames 6, and each of the connecting frames 6 is provided with a set of adjusting screws 7. When using the fixture base 1, the pump body abutment column 8 is placed on the adjusting screw 7 to abut against the pump body to be milled. The same pump body abutment column 8 of the same specification is provided on multiple sets of adjusting screws 7 to limit the position of the pump body to be milled. The pump body abutment column 8 can be selected with different diameters according to the diameter distance at the abutment position of the pump body to be milled, so as to achieve the first layer of adaptability of the tooling fixture in this solution.

[0032] Multiple sets of tilt adjustment columns 5 have the same specifications, and each set of tilt adjustment columns 5 tilts from the inside of the connecting limit frame 9 towards the edge of the clamp base 1. The tilt angle of each set of tilt adjustment columns 5 is the same, which facilitates the replacement of worn or bent tilt adjustment columns 5. The connection position between the tilt adjustment column 5 and the clamp base 1 can be adjusted in multiple positions. When the upper end face of the tilt adjustment column 5 is on the same plane as the setting panel 2, the pump body abutment column 8 on the adjusting screw 7 forms a clamping groove directly between it and the central adjustment column 3 to clamp and limit the edge of the pump body to be milled. When the tilt adjustment column 5 extends from the setting panel 2 at different heights, different abutment seats are set on the central adjustment column 3 to form clamping grooves with different distances from the setting panel 2 between them and the pump body abutment column 8, so as to adapt to the clamping and positioning of the pump bodies to be milled with different outer diameters at the abutment end.

[0033] See Figure 5 The connecting limit frame 9 is welded to the fixture base 1, and the first inclined slot 102 is connected to the second inclined slot 903. During the period when the fixture is designed and put into use, the connecting limit frame 9 and the fixture base 1 are always in a welded connection state, that is, the tilt adjustment column 5 is directly inserted into the first inclined slot 102 from the second inclined slot 903. The diameter of the connecting limit frame 9 is much smaller than the diameter of the fixture base 1. On the basis of being able to accommodate and stabilize multiple sets of tilt adjustment columns 5, the diameter of the connecting limit frame 9 is reduced as much as possible to achieve a certain purpose of saving raw materials. The length of the fixture structure is increased axially to complete the lever-type balance limit of the bottom column of the tilt adjustment column 5 and to provide a space for accommodating the column.

[0034] The inner wall of the first inclined slot 102 is set as the first grinding panel, the inner wall of the second inclined slot 903 is set as the second grinding panel, and the side panel of the tilt adjustment column 5 is set as the third grinding panel. The tilt adjustment column 5 is put into use after the gear adjustment and fixed installation are completed. During the clamping operation of the tilt adjustment column 5, the third grinding panel rubs against the first grinding panel and the second grinding panel in real time, which effectively enhances the contact and limiting stability of the first inclined slot 102 and the second inclined slot 903 on the tilt adjustment column 5, and prevents the tilt adjustment column 5 from loosening under force.

[0035] See Figure 1 and Figure 2 A mounting panel 2 is provided at the center of the upper end face of the fixture base 1. The mounting panel 2 is set below the edge of the fixture base 1. The upper end face of the tilt adjustment column 5 is parallel to the mounting panel 2, and the lower end face of the tilt adjustment column 5 is parallel to the upper end face of the tilt adjustment column 5, which facilitates the installation and use of the lower end face of the tilt adjustment column 5 and the mounting device. The mounting panel 2, together with the upper end face of the tilt adjustment column 5 which is on the same plane, forms the first type of fixture structure for milling the pump body, which completes the limiting support for the pump body. When the tilt adjustment column 5 is not on the same plane as the mounting panel 2, the fixture base 1, together with the mounting panel 2, forms a support and limiting adjustment device for the tilt adjustment column 5.

[0036] The connection between the fixture base 1 and the edge of the mounting panel 2 is provided with a hardened and reinforced edge 101. The hardened and reinforced edge 101 is set as an arc-shaped connecting edge, which effectively enhances the edge structural stress of the fixture base 1 and facilitates the processing of the base. Multiple sets of fixture connecting rods 104 are evenly arranged on the bottom edge of the fixture base 1 for connecting with the fixture assembly to the fixing column at the milling machine mounting end.

[0037] See Figures 5 to 7Each set of tilt adjustment columns 5 is provided with several adjustment through holes 502. The adjustment through holes 502 are parallel to each other along the direction of the tilt adjustment column 5, and the spacing between adjacent adjustment through holes 502 is the same. Multiple sets of adjustment through holes 502 are provided to adjust the specific installation position of the tilt adjustment column 5. By adjusting the adjacent adjustment through holes 502 at different positions to establish a connection with the connecting limit frame 9, the extension distance of the tilt adjustment column 5 on the setting panel 2 can be changed.

[0038] The connecting limit frame 9 is provided with an independent first slot and a second slot at each of the tilt adjustment columns 5. When the tilt adjustment column 5 is in place, the first slot is provided with a first positioning pin 901, which is inserted into a set of adjustment through holes 502 of the tilt adjustment column 5. The second slot is provided with a second positioning pin 902, which is inserted into the next set of adjustment through holes 502 of the tilt adjustment column 5. The connecting limit frame 9 fixes the connection of the connecting limit frame 9 to each set of tilt adjustment columns 5 by aligning the two sets of slots with the two adjacent sets of adjustment through holes 502 on the tilt adjustment column 5, inserting the first positioning pin 901 into the first slot, and inserting the second positioning pin 902 into the second slot.

[0039] See Figure 1 and Figure 5 The fixture base 1 has a central slot 103 in the center, and a central adjusting column 3 is provided in the central slot 103. Several connecting slots 4 are evenly provided on the side of the central adjusting column 3. The spacing between the connecting slots 4 is the same as the spacing between the adjusting through holes 502. When the adjusting through holes 502 at different positions are used to fix the first positioning pin 901 and the second positioning pin 902, the upper end face of the tilting adjusting column 5 protrudes at different positions, and the height and width of each group of adjusting screws 7 are different. It is necessary to change the connection position relationship between each group of abutment seats and the central adjusting column 3 so that the relevant abutment seats can cooperate with the adjusting screws 7 at various locations to complete the limiting abutment of the pump body to be milled, and complete the width between the fixture and the pump body.

[0040] See Figure 1 , Figures 8 to 10 The central adjusting column 3 is provided with a first abutment 31, a second abutment 32, or a third abutment 33. The first abutment 31 has one alignment hole corresponding to the connection port 4, the second abutment 32 has two alignment holes corresponding to the connection port 4, and the third abutment 33 has three alignment holes corresponding to the connection port 4. When the tilting adjusting column 5 extends from the setting panel 2, the distance between it and the setting panel 2 and the distance between it and the central adjusting column 3 will change. Different distances correspond to different abutments placed on the central adjusting column 3 to adapt to the limiting use of pump bodies of different widths, thus completing the second adjustment of the clamp.

[0041] The distance between the central adjusting column 3 and the tilt adjusting column 5 will not change from the setting panel 2. The thickness of the three sets of abutment sidewalls can be changed according to the thickness of the specific pump body edge to adapt to the working requirements of pump body limiting and milling operations with different pump body edge thicknesses, thus completing the third adjustment of the fixture.

[0042] When the first positioning pin 901 is inserted into the uppermost adjustment through hole 502 of the tilt adjustment column 5, and the second positioning pin 902 is inserted into the first set of adjustment through holes 502 below the above-mentioned adjustment through hole 502, the upper end face of the tilt adjustment column 5 is on the same plane as the setting panel 2. At this time, the center adjustment column 3 does not need to be placed with an abutment seat.

[0043] Reference Figure 5 and Figure 8 When the uppermost adjustment through hole 502 of the tilt adjustment column 5 moves upward, the first positioning pin 901 is inserted into the second set of adjustment through holes 502 starting from the top of the tilt adjustment column 5, and the second positioning pin 902 is inserted into the first set of adjustment through holes 502 below the above-mentioned adjustment through hole 502, at this time the first abutment seat 31 with a set of alignment holes is placed on the central adjustment column 3.

[0044] Reference Figure 6 and Figure 9 When the two sets of adjustment through holes 502 at the top of the tilt adjustment column 5 move upward, the first positioning pin 901 is inserted into the third set of adjustment through holes 502 starting from the top of the tilt adjustment column 5, and the second positioning pin 902 is inserted into the first set of adjustment through holes 502 below the aforementioned adjustment through holes 502, at this time, a second abutment seat 32 with two sets of alignment holes is placed on the central adjustment column 3; refer to Figure 7 and Figure 10 When the three sets of adjustment through holes 502 at the top of the tilt adjustment column 5 move upward, the first positioning pin 901 is inserted into the fourth set of adjustment through holes 502 starting from the top of the tilt adjustment column 5, and the second positioning pin 902 is inserted into the first set of adjustment through holes 502 below the above-mentioned adjustment through holes 502, at this time the third abutment seat 33 with three sets of alignment holes is placed on the central adjustment column 3.

[0045] This embodiment only provides four extension positions for the tilt adjustment column. In other embodiments, the tilt angles of the tilt adjustment column 5, the first tilt slot 102, and the second tilt slot 903 can be adjusted within the production allowable range. This, combined with the design of adjustment through holes 502 with different spacings, positioning pins, and mating seats, can improve the adaptability of the fixture. The principles of other embodiments that change the angle and specifications are the same as those in this application, and will not be described again here.

[0046] The upper end of the tilt adjustment column 5 is provided with a set of welding grooves 501, and the bottom of the connecting frame 6 is provided with welding columns. The welding columns are welded to the welding grooves 501. The tilt adjustment column 5 uses the welding grooves 501 to establish a welding connection with the connecting frame 6. The welded connecting frame 6 will not come off the tilt adjustment column 5 during normal use, thereby ensuring the firmness of the connecting frame 6.

[0047] Both the fixture base 1 and the connecting limit frame 9 are solid structures. The fixture base 1, the connecting limit frame 9, and the tilt adjustment column 5 are made of the same material to ensure the stability of the fixture base 1 and the connecting limit frame 9 in limiting the tilt adjustment column 5 and the structural strength of limiting the milling of the pump body. This embodiment does not restrict the material limitation of the fixture structure, but only restricts the fixture structure to be made of the same material to facilitate the generation of mutual forces, ensure the structural strength and hardness of the fixture, and complete the limiting function of milling the pump body.

[0048] This utility model provides a highly adaptable milling fixture, which uses a fixture base 1 and a connecting limit frame 9 to limit the installation of multiple sets of tilt adjustment columns 5. The tilt adjustment columns 5 form a certain angle with the fixture base 1. By changing the position of the tilt adjustment columns 5 on the fixture base 1 and the connecting limit frame 9, the width and height of the connection between the upper end of the tilt adjustment column 5 and the pump body can be changed. In conjunction with the width adjustment of the pump body abutment column 8, the fixture assembly can achieve the abutment limit of the pump body to be milled, thereby improving the adaptability of the fixture assembly.

[0049] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
