Description

Technical Field

[0001] This application relates to the field of lathe fixtures, and more particularly to a tooling fixture. Background Technology

[0002] A milling machine is a machine tool that uses a milling cutter to machine various surfaces of a workpiece. Typically, the rotation of the milling cutter is the primary motion, while the movement of the workpiece and the cutter constitutes the feed motion. It can machine planes, grooves, various curved surfaces, gears, and more. During milling, the workpiece needs to be clamped in a fixture, and then the milling head drives the milling cutter to perform the milling process.

[0003] Existing workpieces such as Figure 1 As shown, it includes a body 1, on which two workpiece holes 2 are milled through both sides of the workpiece thickness direction. A circular arc surface 3 is milled on one side of the body 1 in the thickness direction. Existing workpieces are prone to deformation when directly clamped with a bench vise because they have a through hole in the center. Utility Model Content

[0004] In order to reduce the probability of workpiece deformation under stress when clamped and fixed, this application provides a tooling fixture.

[0005] The tooling fixture provided in this application adopts the following technical solution:

[0006] A tooling fixture includes a platform, on which a milling hole fixing component is provided. The milling hole fixing component has a placement groove. A fixing shaft is provided in the placement groove corresponding to the workpiece hole. A clamping block is slidably disposed on the side wall of the placement groove. The clamping block slides toward the fixing shaft to clamp the workpiece. The fixing shaft is slidably disposed on the milling hole fixing component and is housed in the milling hole fixing component by sliding.

[0007] By adopting the above technical solution, the fixed shaft can support and shape the workpiece hole when the clamping block clamps the workpiece, reducing the probability of the workpiece being deformed by force when it is clamped and fixed. The fixed shaft, which can be slidably set, can be stored in the milling fixing part after the workpiece is fixed and the milling is performed, thereby reducing the impact of the fixed shaft on the milling process.

[0008] Optionally, the milling fixing member has several placement slots evenly formed along the length of the platform.

[0009] By adopting the above technical solution, several placement slots can simultaneously mount multiple workpieces on the fixture, thereby facilitating the machining of workpiece holes for multiple workpieces after a single tooling operation.

[0010] Optionally, the platform is provided with a milling arc fixing component, the milling arc fixing component is provided with a groove, and an air expansion shaft is provided in the groove corresponding to the workpiece hole of the workpiece.

[0011] By adopting the above technical solution, the workpiece is fixed by an air shaft after the groove restricts its position, which facilitates the milling machine to mill the arc surface of the workpiece.

[0012] Optionally, the depth of the groove and the length of the air shaft are both less than half the thickness of the workpiece.

[0013] By adopting the above technical solution, the range of the workpiece's arc surface milling is half the workpiece thickness. The groove and air shaft, which are less than half the workpiece thickness, can reduce the impact on the workpiece's arc surface milling.

[0014] Optionally, the milling arc fixing member has several grooves evenly formed along the length of the platform.

[0015] By adopting the above technical solution, the setting of multiple slots can simultaneously mount multiple workpieces on the fixture, thereby facilitating the machining of the arc surfaces of multiple workpieces after a single tooling setup.

[0016] Optionally, both the milling hole fixing component and the milling arc fixing component can be detachably mounted on the platform, and two of each component are provided on the platform.

[0017] By adopting the above technical solution, both the detachable milling hole fixing component and the milling arc fixing component can be replaced when damaged. Thus, the fixture can still be used normally after replacement when the milling hole fixing component or the milling arc fixing component is damaged, reducing the probability of the fixture being scrapped directly when damaged.

[0018] Optionally, the platform includes a mounting platform and a rotating platform. The milling hole fixing component and the milling arc fixing component can be detachably mounted on the mounting platform. The rotating platform is fixed at the end of the mounting platform and is rotatably mounted on the milling machine tooling table.

[0019] By adopting the above technical solution, the rotary table can be easily connected to the driving components, thereby facilitating the rotation of the table body and enabling milling operations in multiple directions.

[0020] Optionally, the mounting platform is a rectangular platform, and the two milled hole fixing parts and the two milled arc fixing parts are respectively arranged around the rectangular platform. The two milled hole fixing parts are arranged on two opposite sides of the mounting platform, and the two milled arc fixing parts are arranged on two opposite sides of the mounting platform.

[0021] By adopting the above technical solution, the rectangular mounting platform can easily control the rotation angle of the control body, and the milling hole fixing parts and milling arc fixing parts set on the opposite side can easily observe the unprocessed surface to understand what kind of milling process is being performed on the surface being processed, thereby facilitating the observation of whether there are any problems in the processing.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] The fixed shaft can support and shape the workpiece hole when the clamping block clamps the workpiece, reducing the probability of the workpiece being deformed by force when it is clamped and fixed. The fixed shaft, which can be slidably set, can be stored in the milling fixing part after the workpiece is fixed and the milling is performed, thereby reducing the impact of the fixed shaft on the milling process.

[0024] After the workpiece is positioned by the groove, it is fixed by the air shaft, which facilitates the milling machine to mill the arc surface of the workpiece.

[0025] The detachable milling hole fixture and milling arc fixture can be replaced if damaged, so that the fixture can still be used normally after replacement when the milling hole fixture or milling arc fixture is damaged, reducing the probability of the fixture being scrapped directly when damaged;

[0026] By setting the milling arc fixing component and the milling hole fixing component alternately, after milling a hole, the machine can rotate to the milling arc fixing component to mill the arc regardless of whether it rotates forward or backward. This can avoid machining errors caused by incorrect installation, and at the same time, it can be confirmed by looking at one side whether the surface being machined is the milling arc surface or the milling hole surface.

[0031] The following is in conjunction with the appendix Figure 2-3 This application will be described in further detail.

[0032] First, it should be noted that in the description of this application, the use of directional terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" indicates the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used solely for descriptive purposes and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the use of numerical quantifiers such as "first," "second," and "third" is for descriptive purposes only and should not be construed as indicating or implying relative importance. Additionally, in this application, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, interference fits, transition fits, or integral connections; they can refer to direct connections or indirect connections through an intermediate medium. Therefore, those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] This application discloses a tooling fixture, as shown in the embodiments below. Figure 2 The system includes a platform 4, which comprises a rectangular mounting platform 41 and two circular rotating platforms 42 fixed at both ends of the platform 41 along its length. The two circular rotating platforms 42 are coaxially arranged with the center point of the rectangle as their axis. Two milling hole fixing parts 5 and two milling arc fixing parts 9 are detachably mounted on the mounting platform 41. The milling hole fixing parts 5 are used to fix the workpiece for milling the workpiece hole 2, and the milling arc fixing parts 9 are used to fix the workpiece for milling the arc surface 3. The two milling hole fixing parts 5 and the two milling arc fixing parts 9 are respectively set on the four sides of the mounting platform 41. The two milling hole fixing parts 5 are set on two opposite sides of the mounting platform 41, and the two milling arc fixing parts 9 are also set on two opposite sides of the mounting platform 41. By setting the milling arc fixing parts 9 and the milling hole fixing parts 5 alternately, after milling a hole, the platform can rotate to the milling arc fixing part 9 for milling arc regardless of whether it rotates forward or backward. This avoids machining errors caused by incorrect installation and also allows the user to confirm whether the surface being machined is an arc surface or a hole surface by observing one side.

[0034] Reference Figure 2 and Figure 3The milling fixing component 5 has several placement slots 6 evenly distributed along the length of the platform 4. A fixing shaft 7 is provided in each placement slot 6 corresponding to the workpiece hole 2. In this embodiment, two fixing shafts 7 are provided, with their diameters corresponding to the diameters of the two workpiece holes 2. A clamping block 8 is slidably disposed on the side wall of the placement slot 6. The clamping block 8 is driven by an electric push cylinder, which drives the clamping block 8 to be housed in the side wall of the placement slot 6 or to extend towards the fixing shaft 7 to clamp the workpiece. The fixing shaft 7 is slidably disposed on the milling fixing component 5 and is driven by an electric push cylinder. The cylinder-driven fixed shaft 7 supports the workpiece by sliding into or extending out of the milling hole fixing component 5. The fixed shaft 7 can support and shape the workpiece hole 2 when the clamping block 8 clamps the workpiece, reducing the probability of deformation of the workpiece under force when it is clamped and fixed. The fixed shaft 7, which can slide, is retracted into the milling hole fixing component 5 after the workpiece is fixed and milling is performed, thereby reducing the impact of the fixed shaft 7 on the milling process. Since the hole where the fixed shaft 7 is placed is an unmilled hole, the hole diameter cannot reach a uniform standard. Therefore, the fixed shaft 7 is selected with a small diameter and an air expansion function.

[0035] Reference Figure 2 and Figure 3 The milling arc fixing part 9 is provided with a plurality of grooves 10 evenly along the length direction of the platform 4. An air shaft 11 is provided in the groove 10 corresponding to the workpiece hole 2 of the workpiece. In this embodiment, two air shafts 11 with different diameters are provided in the workpiece hole 2 corresponding to the workpiece. The depth of the groove 10 and the length of the air shaft 11 are both less than half the thickness of the workpiece. In this embodiment, the range of the arc surface milled to the workpiece is half the thickness of the workpiece. The groove 10 and the air shaft 11, which are less than half the thickness of the workpiece, can reduce the impact on the arc surface milling of the workpiece.

[0036] The implementation principle of this application embodiment is as follows: First, several batches of workpieces that have not been milled are installed on the milling hole fixing part 5 and clamped and fixed by the fixing shaft 7 and the clamping block 8. Then, the table body 4 is installed in the milling machine to mill the workpiece hole 2. After two to three batches of milling, the unprocessed workpieces are installed on the milling hole fixing part 5, and the workpieces that have been milled are installed on the arc milling fixing part 9. Then, the table body 4 is installed in the milling machine to perform one milling hole and one arc milling. While the milling machine is performing milling hole and arc milling, another batch of workpieces that have not been milled and the workpieces that have been milled are installed on another table body 4 outside the milling machine. After the workpieces on the table body 4 in the milling machine are processed, the table body 4 is replaced and the workpieces on the other table body 4 are processed until all the workpieces to be processed are milled.

[0037] It should be noted that the above embodiments are only used to illustrate this application and are not intended to limit the technical solutions described in this application. Although this specification has described this application in detail with reference to the above embodiments, those skilled in the art should understand that they can still make modifications or equivalent substitutions to this application. All technical solutions and improvements that do not depart from the spirit and scope of this application should be covered within the scope of the claims of this application.
