Description

Technical Field

[0001] This utility model relates to the field of machining technology, and more specifically, to an adjustable fixture and machine tool. Background Technology

[0002] Currently, when machining workpieces on machine tools, in order to ensure that the surface of the workpiece meets the technical requirements such as dimensions and geometric shape specified in the drawings, the workpiece is usually fixed by a fixture before machining to achieve the positioning and clamping of the workpiece.

[0003] In related technologies, most machine tool fixtures are special tooling fixtures that can only fix one type of workpiece, resulting in poor versatility. For example, when the workpiece model is changed, the old fixture is difficult to fix the workpiece, and a matching fixture needs to be replaced, which seriously affects the processing efficiency. Utility Model Content

[0004] The problem this invention solves is how to improve the versatility of fixtures.

[0005] On one hand, this utility model provides an adjustable clamp, including a support base and a clamping structure. The support base has multiple mounting positions for mounting the clamping structure, and the clamping structure can be selectively mounted at the mounting positions. The clamping structure includes a fixed base, a pressure plate, a first rod structure, a first limiting member, and a first telescopic member. The fixed base is detachably connected to the support base. One axial end of the first rod structure is connected to the fixed base. One end of the pressure plate is movably disposed on the first rod structure. The first limiting member is adjustablely mounted on the first rod structure and located on the side of the pressure plate away from the fixed base. One end of the first telescopic member is fixedly connected to one of the pressure plate and the fixed base, and the other end of the first telescopic member contacts the other of the pressure plate and the fixed base along the axial end face of the first rod structure.

[0006] Optionally, the pressure plate is provided with a through adjustment hole, the extension direction of the adjustment hole intersecting the through direction of the adjustment hole; the first rod structure passes through the adjustment hole and is fixedly connected to the fixed seat; the pressure plate is configured to move along the extension direction of the first rod structure or the extension direction of the adjustment hole through the adjustment hole.

[0007] Optionally, the adjustment hole is an oblong hole or a long hole.

[0008] Optionally, the fixed base is provided with a receiving groove, and one end of the first telescopic member is slidably disposed in the receiving groove along the extension direction of the adjustment hole.

[0009] Optionally, the first telescopic member includes a support rod and an auxiliary rod; one end of the support rod is fixedly connected to the pressure plate, and the other end is slidably connected to the auxiliary rod along the telescopic direction of the first telescopic member; the auxiliary rod is supported in the receiving groove and is configured to slide relative to the receiving groove along the extension direction of the adjusting hole.

[0010] Optionally, the part of the auxiliary rod that contacts the receiving groove has an arc-shaped structure.

[0011] Optionally, the first rod structure is provided with an external thread structure, the first limiting member is provided with a through channel, the channel is provided with an internal thread structure, and the first limiting member is threadedly connected to the first rod structure through the internal thread structure and the external thread structure.

[0012] Optionally, it also includes a connector, wherein the mounting position has a first hole structure, the fixing seat has a through second hole structure, and the connector passes through the first hole structure and the second hole structure to connect the fixing seat and the support seat.

[0013] Optionally, the clamping structure has multiple clamping structures, which are evenly distributed on the support base.

[0014] Secondly, this utility model provides a machine tool device, including the adjustable fixture described above.

[0015] Compared with related technologies, the beneficial effects of this utility model are as follows:

[0016] When using an adjustable fixture, adjustments are needed based on the size of the workpiece. First, the fixed base of the clamping structure is installed at a suitable mounting position on the support base to initially position the workpiece. Since one end of the pressure plate is movably mounted on the first rod structure, moving the pressure plate allows it to be positioned above the workpiece. During this process, one end of the first telescopic member is fixedly connected to one of the pressure plate and the fixed base, while the other end, along the axial direction of the first rod structure, contacts the other. Therefore, the length of the first telescopic member can be adjusted as needed to support the other end of the pressure plate. Then, the position of the first limiting member on the first rod structure is adjusted so that it contacts the pressure plate, thus ensuring the pressure plate stably presses against the workpiece. Compared to traditional fixtures that can only fix one type of workpiece, this adjustable fixture can adapt to the size of the workpiece, offering high versatility. Attached Figure Description

[0032] like Figure 1 , 2 As shown, an adjustable clamp according to an embodiment of the present invention includes a support base 100 and a clamping structure 200. The support base 100 has multiple mounting positions for mounting the clamping structure 200, and the clamping structure 200 can be selectively mounted at the mounting positions. The clamping structure 200 includes a fixed base 201, a pressure plate 202, a first rod structure 203, a first limiting member 204, and a first telescopic member 205. The fixed base 201 is detachably connected to the support base 100. One axial end of the first rod structure 203 is connected to the... The fixed base 201 is connected; one end of the pressure plate 202 is movably disposed on the first rod structure 203; the first limiting member 204 is adjustablely installed on the first rod structure 203 and is located on the side of the pressure plate 202 away from the fixed base 201; one end of the first telescopic member 205 is fixedly connected to one of the pressure plate 202 and the fixed base 201, and the other end of the first telescopic member 205 is in contact with the other of the pressure plate 202 and the fixed base 201 along the axial end face of the first rod structure 203.

[0033] In this embodiment, when using the adjustable fixture, it is necessary to adjust it according to the size of the workpiece to be processed. First, the fixed seat 201 of the clamping structure 200 is installed at a suitable mounting position on the support seat 100 to achieve the initial positioning of the workpiece to be processed. Since one end of the pressure plate 202 is movably set on the first rod structure 203, the pressure plate 202 can be moved to make one end of the pressure plate 202 above the workpiece to be processed. During this process, since one end of the first telescopic member 205 is fixedly connected to one of the pressure plate 202 and the fixed seat 201, and the other end of the first rod structure 203 is in contact with the other one of the pressure plate 202 and the fixed seat 201, the length of the first telescopic member 205 can be adjusted as needed to support the other end of the pressure plate 202. Then, the position of the first limiting member 204 on the first rod structure 203 is adjusted so that the first limiting member 204 contacts the pressure plate 202, thereby causing the pressure plate 202 to be stably pressed against the workpiece to be processed. Compared to traditional fixtures that can only fix one type of workpiece, the adjustable fixture of this invention can be adapted to the size of the workpiece to be processed, and has high versatility.

[0034] Optionally, the pressure plate 202 is provided with a through adjustment hole 2021, the extension direction of the adjustment hole 2021 intersecting the through direction of the adjustment hole 2021; the first rod structure 203 passes through the adjustment hole 2021 and is fixedly connected to the fixing seat 201; the pressure plate 202 is configured to move along the extension direction of the first rod structure 203 or the extension direction of the adjustment hole 2021 through the adjustment hole 2021.

[0035] It is important to understand that the extension direction of the adjustment hole 2021 refers to, for example, Figure 3 As shown, the adjustment hole 2021 extends in the direction of the upper surface of the pressure plate 202.

[0036] Specifically, such as Figure 3 As shown, one end of the pressure plate 202 is provided with a through adjustment hole 2021. The extension direction of the adjustment hole 2021 is perpendicular to the through direction of the adjustment hole 2021. The first rod structure 203 passes through the adjustment hole 2021 and is fixedly connected to the fixed base 201. In other words, the first rod structure 203 stands on the fixed base 201, and the pressure plate 202 is sleeved on the first rod structure 203 through the adjustment hole 2021. The pressure plate 202 can move along the extension direction of the first rod structure 203 or the extension direction of the adjustment hole 2021 through the adjustment hole 2021.

[0037] In this optional embodiment, by providing a through adjustment hole 2021 and having its extension direction intersect with the through direction, the pressure plate 202 can move along the extension direction of the adjustment hole 2021 or the extension direction of the first rod structure 203, thereby realizing multi-dimensional adjustment of the pressure plate 202 to meet the clamping requirements of workpieces of different specifications.

[0038] Optionally, the adjustment hole 2021 is an oblong hole or a long hole.

[0039] In this optional embodiment, the design of the oblong or elongated hole provides a wider adjustment range, facilitating flexible adjustment of the part's position during installation to better adapt to different sizes and assembly requirements. Secondly, the shape of the oblong or elongated hole allows the connector 300 to slide within the hole, compensating for errors during part machining and assembly to a certain extent, thus improving assembly accuracy and reliability. Furthermore, the oblong or elongated hole allows for fine-tuning without disassembling the part, facilitating subsequent maintenance and adjustments.

[0040] Optionally, the fixed base 201 is provided with a receiving groove 2012, and one end of the first telescopic member 205 is slidably disposed in the receiving groove 2012 along the extending direction of the adjusting hole 2021.

[0041] Specifically, such as Figure 4 , 5 As shown, the upper part of the fixed base 201 is provided with a receiving groove 2012. The receiving groove 2012 has a communicating opening on the top wall and the adjacent side wall of the fixed base 201. The lower end of the first telescopic member 205 is slidably disposed in the receiving groove 2012 along the extension direction of the adjustment hole 2021.

[0042] In this optional embodiment, the receiving groove 2012 provides a stable sliding path for the first telescopic member 205, ensuring that it can move smoothly in a predetermined direction during the adjustment process.

[0043] Optionally, the first telescopic member 205 includes a support rod 2051 and an auxiliary rod 2052. One end of the support rod 2051 is fixedly connected to the pressure plate 202, and the other end is slidably connected to the auxiliary rod 2052 along the telescopic direction of the first telescopic member 205. The auxiliary rod 2052 is supported in the receiving groove 2012 and is configured to slide relative to the receiving groove 2012 along the extension direction of the adjusting hole 2021.

[0044] Specifically, such as Figure 4 As shown, the upper end of the support rod 2051 is fixedly connected to the pressure plate 202, and the connection method between the two includes, but is not limited to, adhesive bonding, plugging, or snap-fitting; Figure 6As shown, the auxiliary rod 2052 is provided with a slide 20521 with an upper opening. The lower end of the support rod 2051 is slidably disposed in the slide 20521. The auxiliary component is slidably disposed in the receiving groove 2012, and the upper end surface of the auxiliary component is flush with the upper end surface of the fixed seat 201, and the lower end surface of the auxiliary component is in contact with the bottom wall of the receiving groove 2012.

[0045] In this optional embodiment, the lower end of the support rod 2051 is slidably connected to the auxiliary rod 2052 along the telescopic direction of the first telescopic member 205. In this way, when adjusting the height of the pressure plate 202, the relative positions of the support rod 2051 and the auxiliary rod 2052 can be adjusted, so that the bottom end of the auxiliary rod 2052 is always in contact with the bottom wall of the receiving groove 2012, so as to balance the force on the pressure plate 202 when the first limiting member 204 presses the pressure plate 202.

[0046] Furthermore, the outer wall of the upper end of the auxiliary rod 2052 is provided with a threaded hole 20522 that communicates with its slide rail 20521. The threaded hole 20522 is fitted with a threaded rod. By rotating the threaded rod, the threaded rod can be made to abut against the support rod 2051 inside the slide rail 20521, thereby achieving the fixation between the support rod 2051 and the auxiliary rod 2052.

[0047] Optionally, the part of the auxiliary rod 2052 that contacts the receiving groove 2012 has an arc-shaped structure.

[0048] Specifically, such as Figure 6 As shown, the auxiliary rod 2052 is cylindrical in shape and its bottom end is hemispherical. When the auxiliary rod 2052 is located in the receiving groove 2012, the circumferential sidewall of the auxiliary rod 2052 is in contact with the sidewall of the receiving groove 2012, and the bottom end of the auxiliary rod 2052 is in contact with the bottom wall of the receiving groove 2012.

[0049] In this optional embodiment, when the support rod 2051 moves along the extension direction of the adjustment hole 2021 following the pressure plate 202, the auxiliary rod 2052 can move in the receiving groove 2012. Since the part of the auxiliary rod 2052 that contacts the receiving groove 2012 has an arc-shaped structure, this design can effectively reduce the stress concentration at the contact part, improve the strength and durability of the structure, and at the same time, the arc-shaped structure can also make the auxiliary rod 2052 slide more smoothly in the receiving groove 2012, reduce friction and wear, and further improve the stability and reliability of the clamping structure 200.

[0050] Optionally, the first rod structure 203 is provided with an external thread structure 2031, the first limiting member 204 is provided with a through channel 2041, the channel 2041 is provided with an internal thread structure 2042, and the first limiting member 204 is threadedly connected to the first rod structure 203 through the internal thread structure 2042 and the external thread structure 2031.

[0051] Specifically, such as Figure 7 As shown, the first rod structure 203 is a threaded rod structure, and its circumferential sidewall is provided with an external thread structure 2031; as Figure 8 As shown, the first limiting member 204 is a nut, which has a through channel 2041. The inner wall of the channel 2041 has an internal thread structure 2042. The first limiting member 204 is sleeved on the first rod structure 203 and is threadedly connected to the first rod structure 203.

[0052] In this optional embodiment, the first rod structure 203 and the first limiting member 204 are connected by external and internal threads, which can provide a reliable mechanical connection and ensure a tight fit between the first rod structure 203 and the first limiting member 204. Furthermore, by rotating the first limiting member 204, the position of the first limiting member 204 on the first rod structure 203 can be adjusted, facilitating the restriction of the pressing position of the pressure plate 202.

[0053] Optionally, the adjustable clamp further includes a connector 300, a first hole structure 101 is provided at the mounting position, a second through hole structure 2011 is provided at the fixing seat 201, and the connector 300 passes through the first hole structure 101 and the second hole structure 2011 to connect the fixing seat 201 and the support seat 100.

[0054] Specifically, such as Figure 9 As shown, a first hole structure 101 is provided at the mounting position, and the first hole structure 101 is a threaded hole 20522; as Figure 10 As shown, the fixing base 201 is provided with a through second hole structure 2011, that is, the second hole structure 2011 is a through hole structure 102; the connecting member 300 is a bolt, the shank of the bolt passes through the second hole structure 2011 and is threaded into the first hole structure 101, and the head of the bolt is pressed against the fixing base 201 at the position where the second hole structure 2011 is provided.

[0055] In this optional embodiment, when installing the clamping structure 200, the clamping structure 200 is first moved to a suitable installation location, and the second hole structure 2011 on the fixing base 201 is aligned with the first hole structure 101 at the installation location. Then, the connecting member 300 passes through the first hole structure 101 and the second hole structure 2011 to connect the fixing base 201 and the support base 100, thereby fixing the clamping structure 200 in the suitable installation location. This connection method not only improves the overall structural stability of the fixture but also facilitates disassembly and assembly, allowing users to adjust and maintain the fixture according to actual needs.

[0056] Furthermore, a second hole structure 2011 can be connected to a first hole structure 101 or to multiple second hole structures 2011. There are no restrictions here; it depends on the actual needs.

[0057] Furthermore, such as Figure 5 As shown, the end face of the fixed base 201 away from the support base 100 is provided with a groove structure 2013, and a second hole structure 2011 is provided in the bottom wall of the groove structure 2013. The head of the connector 300 is located in the groove structure 2013. In this way, the groove structure 2013 can not only hide the head of the connector 300 to protect the connector 300, but also reduce the length of the connector 300 in the fixed base 201 due to the presence of the groove structure 2013, thereby saving the cost of the connector 300.

[0058] In this embodiment, the number of first hole structures 101 is not limited and depends on actual needs. Preferably, there are two or more. In this way, when there are two first hole structures 101, the probability of the fixed base 201 rotating axially around the connector 300 can be reduced.

[0059] Optionally, there are multiple clamping structures 200, and the multiple clamping structures 200 are evenly distributed on the support base 100.

[0060] Specifically, the number of clamping structures 200 is not limited and depends on actual needs. As shown in the figure, a through hole structure 102 is provided at the center of the support base 100, and the number of clamping structures 200 is eight. The eight clamping structures 200 are arranged around the through hole structure 102. The eight clamping structures 200 can be located in the same circumference or in different circumferences.

[0061] In this optional embodiment, the multiple evenly arranged clamping structures 200 ensure that the clamping force is applied evenly to all parts of the clamped object, avoiding deformation or slippage caused by uneven force, thereby improving clamping accuracy and safety. Simultaneously, the synergistic effect of the multiple clamping structures 200 can adapt to objects of different shapes and sizes, enhancing the versatility and applicability of the fixture, enabling it to meet diverse industrial production or operational needs.

[0062] Another embodiment of the present invention provides a machine tool device including the adjustable fixture described above.

[0063] The machine tool equipment in this embodiment has the same beneficial effects as the adjustable fixture described above relative to related technologies, so it will not be described again here.

[0064] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
