Description

Technical Field

[0001] The invention belongs to the field of clamps, and in particular relates to a clamp with an adjustable supporting device. Background Art

[0002] A fixture is a tooling with a complete product positioning and orientation. It is used to fix and position various workpieces during the processing process to facilitate the subsequent processing. The fixture usually has a variety of clamping workpieces and has a strong comprehensive fixing ability, so it is widely used in various product processing processes. The fixture is a key structure for installing the workpiece and will directly affect the performance and processing accuracy of the product.

[0003] Usually, a support device is provided on the bottom plate of the fixture to support the workpiece. When in use, the workpiece to be processed will be provided with a support point that matches the support device on the fixture, so that the fixture can better clamp the workpiece and prevent the workpiece from moving during the processing and causing errors in the processing results.

[0004] However, in the actual processing, long-term processing may cause the workpiece support point to deform. Currently, most support devices are fixed. When the workpiece support point is deformed, the clamp support will be abnormal when it needs to be re-clamped for the next process. In the case of clamping deformation, the product processing size will be unstable. Summary of the invention

[0005] In response to one or more of the above defects or improvement needs in the prior art, the present invention provides a clamp with an adjustable support device, which can ensure that the clamp support remains unchanged when the workpiece to be processed is clamped for a long time so that it is deformed, and further ensure the stability of the processing size of the workpiece to be processed.

[0006] To achieve the above-mentioned object, the present invention provides a clamp with an adjustable support device, comprising a clamp plate, characterized in that at least one adjustable support device is provided on the clamping surface of the clamp plate, and the adjustable support device comprises a base and a support ball;

[0007] The base is mounted on the clamping surface of the fixture plate, and a receiving groove is provided on the top surface of the base;

[0008] Part of the support ball is embedded in the receiving groove in a gap-matched manner, and the other part thereof protrudes from the receiving groove. A support surface is provided on the part of the support ball protruding from the receiving groove, and the support surface angle can be changed by rotating the support ball in the receiving groove.

[0009] As a further improvement of the present invention, the base is further provided with an adjustment hole communicating with the containing groove;

[0010] The adjustable support device also includes an adjustment component, which includes an action member and an adjustment member. One end of the action member passes through the adjustment hole to abut against the embedding position of the support ball, and the other end abuts against the adjustment member. Under the action of the adjustment member, the action member can move in the adjustment hole and adjust the depth of the support ball embedded in the accommodating groove.

[0011] As a further improvement of the present invention, the acting member is an adjusting ball, the adjusting member thread is matched with the adjusting hole, and the adjusting ball can move in the adjusting hole under the push of the adjusting member.

[0012] As a further improvement of the present invention, the diameter of the adjusting ball is not greater than the diameter of the supporting ball.

[0013] As a further improvement of the present invention, the action member and the adjustment member are an integrally formed adjustment rod that can reciprocate and telescopically move in the adjustment hole, one end of the adjustment rod extends into the accommodating groove and abuts against the embedded part of the support ball;

[0014] The adjusting rod is a screw matched with the thread of the adjusting hole; or, a driving mechanism is provided at one end of the adjusting rod away from the supporting ball to realize telescopic driving of the adjusting rod in the adjusting hole.

[0015] As a further improvement of the present invention, a limiting plate with a certain thickness is connected to the support surface.

[0016] As a further improvement of the present invention, the accommodating groove is a curved groove.

[0017] As a further improvement of the present invention, the base is fixedly or detachably or adjustably connected to the clamping surface of the clamp plate.

[0018] As a further improvement of the present invention, the base is detachably connected to the clamping surface of the clamp plate, and a connecting hole is further provided on the base, through which a connecting member can connect the base to the clamp plate.

[0019] As a further improvement of the present invention, the base can be adjustably connected to the clamping surface of the clamping plate, the clamping plate is connected with a screw, and the base is also provided with a threaded hole matching the thread. The base can move along the screw through the threaded hole to adjust the distance between the base and the clamping surface of the clamping plate.

[0020] The above-mentioned improved technical features can be combined with each other as long as they do not conflict with each other.

[0021] In general, compared with the prior art, the above technical solution conceived by the present invention has the following beneficial effects:

[0022] (1) The clamp with an adjustable support device of the present invention has a receiving groove on the base, so that the support ball with a support surface can rotate in the receiving groove and the angle of the support surface can be changed, so that the support ball can quickly fit with the support point of the workpiece to be processed. Moreover, even if the support point is clamped and deformed, the support surface can adjust the angle according to actual needs to achieve good support for the deformed support point and ensure that the support position of the workpiece to be processed by the adjustable support device under different deformations meets the processing requirements, so that the final processing size of the workpiece meets the set standard.

[0023] (2) The clamp with an adjustable support device of the present invention has support balls that can fit with the surfaces of workpieces of different shapes, so that workpieces of different shapes can all fit well with the support balls, and the support balls are flexible in movement. When the workpiece to be processed changes, the support balls can compensate for the change of the workpiece under the support of the adjustment member, thereby ensuring that the support position remains unchanged.

[0024] (3) The clamp with an adjustable support device of the present invention, through the receiving groove connected to the adjustment hole and the adjustment component abutting the support ball through the adjustment hole, enables the active member in the adjustment component to adjust the depth of the support ball accommodated in the receiving groove under the drive of the adjustment component, and can further fine-tune the height of the support position. Furthermore, the base is also provided with a threaded hole that can match the screw provided on the clamp plate, and can roughly adjust the overall position of the base, so that the support position can be greatly adjusted to meet the support position of different requirements.

[0025] (4) The clamp with an adjustable support device of the present invention has a simple structure, is easy to install, and has a good automatic alignment function. It can effectively correct the support points of the deformed workpiece to avoid the workpiece being compressed and deformed so that the support points are deformed and incorrect support is caused, thereby resulting in poor processing dimensions. It has good application prospects and practical value. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Example:

[0043] See also Figure 1~Figure 4 The clamp with an adjustable support device in the preferred embodiment of the present invention comprises a clamp plate 1, and at least one adjustable support device 2 is arranged on the clamping surface of the clamp plate 1, and the adjustable support device 2 comprises a base 201 and a support ball 202. The base 201 is mounted on the clamping surface of the clamp plate 1, and a receiving groove 2011 is provided on the top surface thereof. Specifically, a part of the support ball 202 is embedded in the receiving groove 2011 in a gap-matching manner, and another part thereof protrudes from the receiving groove 2011, and a support surface 2021 is provided on the part of the support ball 202 protruding from the receiving groove 2011, and the angle of the support surface 2021 can be changed by the rotation of the support ball 202 in the receiving groove 2011.

[0044] It can be understood that the angle-adjustable support surface 2021 can quickly fit the support point of the workpiece 4 to be processed regardless of whether it is deformed or not, thereby achieving good support for the deformed support point and ensuring that the support position of the adjustable support device 2 for the workpiece 4 to be processed under different deformations meets the processing requirements, so that the final processing size of the workpiece meets the set standard.

[0045] Specifically, the number of adjustable support devices 2 can be set according to the needs. If only one support point of the workpiece 4 to be processed is easily deformed, the original fixed support device at that point can be replaced with an adjustable support device 2. Since the adjustable support device 2 of the present invention can play a good supporting role for the support point regardless of whether it is deformed, it is also feasible to replace all the original fixed support devices with adjustable support devices 2.

[0046] Further, the base 201 is fixedly or detachably or adjustably connected to the clamping surface of the clamp plate 1. When fixedly connected, the base 201 can be integrally formed with the clamp plate 1 or welded to the clamp plate 1. In a preferred embodiment, the base 201 is detachably connected to the clamp plate 1, which is convenient for replacing the support device according to actual processing conditions. Specifically, a connecting hole 2013 is also provided on the base 201, and a connecting member (not shown in the figure) connects the base 201 to the clamp plate 1 through the connecting hole 2013.

[0047] Meanwhile, in the preferred embodiment, the base 201 can also be adjusted to be connected to the clamping surface of the clamping plate 1. A screw is provided on the clamping surface of the clamping plate 1, and a threaded hole (not shown in the figure) matching the screw is provided on the base 201, so that the base 201 can move along the screw through the threaded hole, thereby adjusting the distance between the base 201 and the clamping surface of the clamping plate 1, so that the height of the support ball 202 provided on the base 201 can also be greatly changed, so that the adjustable support device 2 can adapt to more different support requirements.

[0048] Furthermore, in the preferred embodiment, the clamp further comprises a pressing device 3, such as Figure 2 As shown, the clamping device 3 is arranged corresponding to the adjustable supporting device 2 , and is usually arranged just above the supporting point of the workpiece 4 to be processed, so as to be able to clamp the workpiece 4 to be processed onto the adjustable supporting device 2 .

[0049] Preferably, a limiting plate with a certain thickness is connected to the support surface 2021 (not shown in the figure). When the support ball 202 rotates in the receiving groove 2011, when the narrower support surface 2021 part turns to the bottom of the opening of the receiving groove 2011, it is easy to make the support ball 202 flip over, which is not conducive to subsequent support. After the limiting plate with a certain thickness is connected to the support surface 2021, when the support surface 2021 turns to the opening of the receiving groove 2011, it will be limited by the limiting plate, which prevents the support surface 2021 from continuing to turn downward so that the support ball 202 flips over, which is conducive to subsequent support.

[0050] More preferably, the receiving groove 2011 is a curved groove, which can be a semicircular groove with a diameter slightly larger than the supporting ball 202, so that it can rotate in the receiving groove 2011 but cannot move, and is well embedded in the receiving groove 2011, and can play a role of stable support. On this basis, in the preferred embodiment, a flat plate can be set on the receiving groove 2011 to limit the rotation of the supporting ball 202 according to the requirements to match the size of the supporting ball 202, further avoiding the flipping of the supporting ball 202.

[0051] More preferably, if Figure 4 As shown, in the preferred embodiment, the base 201 is further provided with an adjustment hole 2012 communicating with the receiving groove 2011. The adjustable support device 2 also includes an adjustment component 203, which includes an action member and an adjustment member 2032. One end of the action member passes through the adjustment hole 2012 and abuts against the embedded part of the support ball 202, and the other end thereof abuts against the adjustment member 2032. Under the action of the adjustment member 2032, the action member can move in the adjustment hole 2012 and adjust the depth of the support ball 202 embedded in the receiving groove 2011.

[0052] In detail, Figure 3 As shown, in the preferred embodiment, the acting member is an adjusting ball 2031, and the adjusting member 2032 is threadedly matched with the adjusting hole 2012. The adjusting ball 2031 can move in the adjusting hole 2012 under the push of the adjusting member 2032. When the adjusting member 2032 pushes the adjusting ball 2031 to move, the adjusting ball 2031 can further push the supporting ball 202 abutting against it to a depth embedded in the receiving groove 2011. When the adjusting member 2032 does not move, the adjusting ball 2031 can also be well stationary in the adjusting hole 2012, and no adjustment error will be caused.

[0053] In a preferred embodiment, the diameter of the adjusting ball 2031 is not greater than the diameter of the supporting ball 202 , so that the adjustment process is faster and more convenient and it is easy to set more adjusting balls 2031 .

[0054] In more detail, Figure 3 As shown, there are three adjustment holes 2012 and they are parallel to the surface of the base 201. More preferably, the three adjustment holes 2012 are arranged at the same interval, so that the adjustment balls 2031 arranged in the adjustment holes 2012 are in a stable equilateral triangle as a support, which can provide more stable support on the basis of adjustment. Specifically, in the preferred embodiment, the adjustment balls 2031 are steel balls. The steel balls arranged in a triangle can evenly share the force and will not be easily deformed, and can better play a role in stable support. In the specific setting, the same number of adjustment balls 2031 are placed in each adjustment hole 2012, and multiple adjustment balls 2031 can share the force to ensure a more stable support.

[0055] In other embodiments, the action member and the adjustment member 2032 are integrally formed as an adjustment rod (not shown in the figure) that can reciprocate and telescope in the adjustment hole 2012, and one end of the adjustment rod extends into the receiving groove 2011 and abuts against the embedded part of the support ball 202. In this way, the embedded depth of the support ball 202 can be adjusted directly by adjusting one end of the adjustment rod.

[0056] In a specific embodiment, the adjustment rod is a screw rod that matches the thread of the adjustment hole 2012 , and the staff can adjust the position of the other end of the screw rod extending into the receiving groove 2011 by adjusting the screw rod, thereby adjusting the embedding depth of the support ball 202 .

[0057] In another specific embodiment, a driving mechanism is provided at the end of the corresponding adjusting rod away from the supporting ball 202 to realize the telescopic driving of the adjusting rod in the adjusting hole 2012 .

[0058] At this time, the adjustment hole 2012 can be set perpendicular to the plane of the base 201, usually set to one (not shown in the figure). It can be understood that when set in this way, the adjustment rod can also play a certain supporting role, and can share part of the force when the force is large, playing a more stable supporting role than the base 201.

[0059] During installation, the adjustable support device 2 is fixedly connected to the fixture with the side provided with the receiving groove 2011 facing upward, so that the support ball 202 placed in the receiving groove 2011 can contact the workpiece 4 to be processed. The clamping device 3 is preferably a clamping oil cylinder, which is arranged corresponding to the support device, usually arranged just above the support point of the workpiece 4 to be processed, and can play a supporting role at the same time as the support role below the support point of the workpiece 4 to be processed, so that the clamping effect is good.

[0060] The clamp and the clamp with adjustable support device of the present invention have support balls that can fit with the surfaces of workpieces of different shapes, so that workpieces of different shapes can all fit well with the support balls, and the support balls are flexible to move. When the workpiece to be processed changes, the support balls can compensate for the change of the workpiece under the support of the adjustment member to ensure that the support position remains unchanged. In addition, it has a simple structure, is easy to install, has a good automatic alignment function, can effectively correct the support point of the corresponding deformed workpiece, and avoids the workpiece being deformed by pressure deformation, which causes the support point to deform and cause incorrect support, thereby resulting in poor processing size, and has good application prospects and practical value.

[0061] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
