Description

Technical Field

[0001] The utility model relates to the field of honing equipment, and specifically provides a clamp used for honing equipment and the honing equipment. Background Art

[0002] Honing is a method of finishing holes using a honing head with grinding strips (oilstones). During the honing process, the workpiece is fixed, and the honing head is driven by the machine tool spindle to rotate and reciprocate in a straight line. At the same time, the grinding strips act on the workpiece surface with a certain pressure, cutting off a very thin layer of material from the workpiece surface. The cutting track left on the hole wall is usually a cross-net pattern.

[0003] In the honing process of thin-walled workpieces, it is difficult for the fixtures in the prior art to apply uniform clamping force to the workpiece. When the local clamping force is insufficient, the honing head is likely to deform the local area (for example, the notch is deformed) during cutting, thereby failing to ensure the machining accuracy of the hole.

[0004] Therefore, this field needs a new technical solution to solve the above problems. Utility Model Content

[0005] In order to solve the problem of uneven clamping force distribution of the clamp used for honing equipment in the prior art, the utility model provides a clamp for honing equipment. The clamp of the utility model comprises: a plurality of clamping blocks, each of which is provided with a first pressure-bearing portion and a second pressure-bearing portion at both ends, and the clamping block is suitable for being arranged on the outside of the workpiece along the circumferential direction; a first clamping member, the first clamping member comprises a first receiving groove, the first receiving groove comprises a first opening and a first circumferential wall, the first circumferential wall is inclined toward the first opening, at least part of the first pressure-bearing portion is accommodated in the first receiving groove and can slide along the first circumferential wall; and a second clamping member, the second clamping member is detachably connected to the first clamping member and comprises a second receiving groove, the second receiving groove comprises a second opening and a second circumferential wall, the second circumferential wall is inclined toward the second opening, at least part of the second pressure-bearing portion is accommodated in the second receiving groove and can slide along the second circumferential wall, and the first clamping member and the second clamping member can drive the clamping block to move toward the workpiece when they are close to each other.

[0006] The clamp of the utility model comprises a clamp block with two pressure-bearing parts, so that the clamping force applied by the clamp block to the workpiece to be processed can be evenly distributed along the length direction of the clamp block. The clamp block is arranged on the outer side of the workpiece along the circumferential direction, so that multiple clamp blocks can apply clamping force to the workpiece from different directions, and each clamp block can better fit the outer surface of the workpiece locally, overcoming the problem that the traditional clamp that relies on fixed size to constrain the workpiece cannot completely fit the workpiece with dimensional tolerance. The first clamping member comprises a first receiving groove, and at least part of the first pressure-bearing part is accommodated in the first receiving groove. The second clamping member comprises a second receiving groove, and at least part of the second pressure-bearing part is accommodated in the second receiving groove. Therefore, the first clamping member and the second clamping member can lock the clamp block from both ends of the clamp block to keep the clamp block stable. The first receiving groove comprises a first opening and a first circumferential wall, and the first circumferential wall is inclined toward the first opening. The second receiving groove comprises a second opening and a second circumferential wall, and the second circumferential wall is inclined toward the second opening. Through the above configuration, the first pressure-bearing part generates displacement in two directions when sliding relative to the first circumferential wall, that is, it moves toward the workpiece and also moves toward the bottom of the first receiving groove. Similarly, the second pressure-bearing portion also generates displacement in two directions when sliding relative to the second circumferential wall, that is, it moves toward the workpiece and also moves toward the bottom of the second receiving groove. In other words, when the first clamping member and the second clamping member approach each other, the clamping block can be driven to generate displacement toward the workpiece, so as to achieve the effect of each clamping block synchronously squeezing the workpiece from multiple points and evenly distributing the clamping force.

[0007] In the preferred technical solution of the clamp for honing equipment, the first pressure-bearing part includes a first inclined surface matched with the first circumferential wall, and at least a portion of the first inclined surface can abut against the first circumferential wall; the second pressure-bearing part includes a second inclined surface matched with the second circumferential wall, and at least a portion of the second inclined surface can abut against the second circumferential wall. Through the above configuration, the inclined surface not only increases the pressure area of ​​the pressure-bearing part, but also the cooperation of the two surfaces also limits the moving direction of the clamp, thereby improving the stability of the clamp during the tightening or loosening process.

[0008] In the preferred technical solution of the clamp for honing equipment, the first clamp and the second clamp are connected by a thread, and the first clamp and the second clamp are close to each other when rotating in the forward direction of the thread, and are away from each other when rotating in the reverse direction of the thread. Through the setting of the thread, the clamp has a higher adjustment accuracy of the clamping force, so as to provide a proper clamping force for the workpiece, and avoid the clamping force being too small to affect the honing effect or the clamping force being too large to damage the workpiece.

[0009] In the preferred technical solution of the clamp for honing equipment, the first clamp includes an external threaded portion formed on the outer wall of the first clamp; the second clamp includes a stopper surface and a connecting portion, the second opening is formed on the stopper surface, the connecting portion protrudes outward from the stopper surface and surrounds the outer side of the second opening, and the inner wall of the connecting portion is provided with an internal threaded portion matching the external threaded portion. Through the above arrangement, the first clamp and the second clamp are compact in structure and can be configured as a rotating body to improve the production efficiency of the clamp.

[0010] In the preferred technical solution of the clamp for honing equipment, the clamp includes a guide portion, and the guide portion is used to guide the first clamp and the second clamp to approach or move away from each other along the center line direction of the external threaded portion. By setting the guide portion, jamming is avoided when the first clamp and the second clamp rotate relative to each other along the thread, thereby improving the clamping efficiency of the clamp.

[0011] In the preferred technical solution of the clamp for honing equipment, the guide portion includes an annular flange arranged on the outer wall of the first clamp; the guide portion also includes a guide groove arranged on the inner wall of the connecting portion, at least part of the annular flange is accommodated in the guide groove, and the outer wall surface of the annular flange forms a clearance fit with the inner wall surface of the guide groove. Through the above arrangement, the annular flange and the guide groove matched with the annular flange can meet the requirements of processing the first clamp and the second clamp into a rotating body, so as to improve the production efficiency of the clamp. The outer wall surface of the annular flange forms a clearance fit with the inner wall surface of the guide groove, which can ensure that the rotation between the first clamp and the second clamp generated by the thread is relatively smooth, and at the same time, the guide portion can still play the effect of moving the first clamp and the second clamp roughly along the center line direction of the external threaded portion.

[0012] In the preferred technical solution of the clamp for honing equipment, the clamp further includes an elastic reset member; a mounting groove for accommodating the elastic reset member is formed on the side of each clamping block facing the workpiece, and when the first clamping member and the second clamping member move away from each other, the elastic reset member can drive the clamping block away from the workpiece. Through the above arrangement, when the first clamping member and the second clamping member move toward each other to drive the clamping block to press the workpiece, the elastic reset member is compressed. When the first clamping member and the second clamping member move in opposite directions, the clamping force of the clamping member on the clamping block decreases, and the elastic reset member gradually resets and drives the clamping block away from the workpiece, so as to achieve the effect of releasing the workpiece so that it can be taken out by the operator.

[0013] In the preferred technical solution of the fixture for honing equipment, the bottom of the first receiving groove is provided with a through hole, and the through hole is suitable for passing the workpiece or the honing head of the honing equipment. Through the above configuration, the workpiece can be placed in the center of the plurality of clamping blocks through the through hole without disassembling the first clamping member; the honing head can extend through the through hole into the hole to be processed of the workpiece to hone the workpiece.

[0014] In the preferred technical solution of the clamp for the honing device, a connection plate is provided on the outer wall of the second clamping member, and the connection plate is suitable for forming a fixed connection with the honing device. Through the above configuration, the position of the second clamping member is relatively fixed, and the workpiece can be clamped or released by moving the first clamping member.

[0015] The utility model also provides a honing device. The honing device of the utility model includes the fixture for the honing device in the above preferred technical solution. Through the setting of the fixture of the utility model, the honing device can ensure the processing accuracy of thin-walled workpieces. BRIEF DESCRIPTION OF THE DRAWINGS

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] In order to solve the problem of uneven clamping force distribution of the clamp used for honing equipment in the prior art, the utility model provides a clamp 100 for honing equipment. The clamp 100 of the utility model comprises: a plurality of clamping blocks 10, each of which is provided with a first pressure-bearing portion 14 and a second pressure-bearing portion 15 at both ends, and the clamping blocks 10 are suitable for being arranged on the outside of the workpiece 500 along the circumferential direction; a first clamping member 30, the first clamping member 30 comprises a first receiving groove 31, the first receiving groove 31 comprises a first opening 311 and a first circumferential wall 312, the first circumferential wall 312 is inclined toward the first opening 311, at least a portion of the first pressure-bearing portion 14 is accommodated in the first receiving groove 31 and can be arranged along the first circumferential wall 312 sliding; and a second clamping member 40, the second clamping member 40 is detachably connected to the first clamping member 30 and includes a second accommodating groove 41, the second accommodating groove 41 includes a second opening 411 and a second circumferential wall 412, the second circumferential wall 412 is inclined toward the second opening 411, at least part of the second pressure-bearing portion 15 is accommodated in the second accommodating groove 41 and can slide along the second circumferential wall 412, and when the first clamping member 30 and the second clamping member 40 are close to each other, the clamping block 10 can be driven to move toward the workpiece 500.

[0027] Figure 1 It is a schematic assembly diagram of an embodiment of a fixture for honing equipment of the utility model; Figure 2 It is an exploded view of an embodiment of the clamp for honing equipment of the utility model; Figure 3 yes Figure 1 A cross-sectional view of an embodiment of a fixture for a honing apparatus is shown.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the fixture 100 for honing equipment of the present invention comprises a plurality of clamping blocks 10, a first clamping member 30 and a second clamping member 40. The workpiece 500 is suitable for being arranged in the area surrounded by the plurality of clamping blocks 10. The clamping blocks 10 are in direct contact with the workpiece 500 to be processed to clamp the workpiece 500.

[0029] Continue reading Figure 2 and Figure 3 In one or more embodiments, the clamp 100 of the present invention includes five clamping blocks 10. The five clamping blocks 10 are arranged at equal intervals along the circumferential direction on the outside of the workpiece 500. Figure 3 , the side of the clamping block 10 facing the workpiece 500 is the first side 11, and the first side 11 is configured to be an arc surface to adapt to the rotating workpiece 500. Alternatively, the first side 11 may also be configured to be other suitable shapes to adapt to workpieces 500 of other shapes. Alternatively, the clamping blocks 10 may also be configured to be other suitable numbers, but it is necessary to ensure that the clamping blocks 10 can provide the necessary clamping force. Exemplarily, when the number of the clamping blocks 10 is 2, the clamping blocks 10 need to be configured roughly opposite to each other to avoid setting the two clamping blocks 10 on the same side of the workpiece 500. Alternatively, the clamping blocks 10 may also be configured to form different spacing distances from each other.

[0030] In one or more embodiments, the clamp 100 further includes an elastic return member 20. The elastic return member 20 is configured as an elastic retaining ring. An inwardly recessed mounting groove 13 is formed on the first side 11 of each clamp 10. The mounting groove 13 on each clamp 10 accommodates part of the elastic retaining ring. When a force is applied to the multiple clamps 10, their inward contraction movement (i.e., moving toward the workpiece 500) will compress the elastic retaining ring. When the force on the clamp 10 is reduced or removed, the compressed elastic retaining ring will restore its original shape and drive the clamp 10 to expand outward (i.e., away from the workpiece 500). Alternatively, the setting of the elastic retaining ring and the mounting groove 13 can also be cancelled, and other suitable structures can be used to enable the clamp 10 to expand outward when the force on the clamp 10 is reduced or removed. Exemplarily, the elastic return member 20 can also be configured as a spring wire, a torsion spring structure, etc., and accordingly, the mounting groove 13 is also replaced with other structures that can be compatible with the spring wire, the torsion spring structure, etc.

[0031] Continue reading Figure 2 and Figure 3 In one or more embodiments, each clamp block 10 has a first pressure-bearing portion 14 at one end and a second pressure-bearing portion 15 at the other end opposite thereto. The first pressure-bearing portion 14 includes a first inclined surface 141, and the second pressure-bearing portion 15 includes a second inclined surface 151. Figure 3, the side of the clamping block 10 facing away from the workpiece 500 is the second side 12, and the first inclined surface 141 and the second inclined surface 151 are both arranged on the second side 12. The height of the first inclined surface 141 relative to the first side 11 gradually decreases in the direction away from the middle part of the clamping block 10, and similarly, the height of the second inclined surface 151 relative to the first side 11 also gradually decreases in the direction away from the middle part of the clamping block 10. Alternatively, the first pressed portion 14 and the second pressed portion 15 can also be configured into other suitable shapes according to actual needs.

[0032] Figure 4 1 is a schematic structural diagram of an embodiment of the first clamping member of the clamp for honing equipment of the utility model. Figure 3 and Figure 4 As shown, in one or more embodiments, the first clamping member 30 is configured as a substantially cylindrical body of revolution for ease of processing. A first receiving groove 31 is formed on the first clamping member 30, and the first receiving groove 31 is used to accommodate at least a portion of each first pressure-bearing portion 14. The first receiving groove 31 has a first opening 311 and a first circumferential wall 312. The first circumferential wall 312 is an inner wall of the first receiving groove 31. The first circumferential wall 312 is inclined toward the first opening 311, and the first pressure-bearing portion 14 can slide along the first circumferential wall 312. When the first pressure-bearing portion 14 slides along the first circumferential wall 312, it generates displacement in two directions, that is, it moves toward the workpiece 500 while also moving toward the bottom of the first receiving groove 31 opposite to the first opening 311.

[0033] In one or more embodiments, a through hole 32 is provided at the bottom of the first receiving groove 31, and the workpiece 500 or the honing head can pass through the through hole 32. Alternatively, the through hole 32 for passing the workpiece 500 or the honing head can also be provided on the second clamping member 40.

[0034] Continue reading Figure 3 and Figure 4In one or more embodiments, an external threaded portion 33 is provided on the outer wall of the first clamping member 30. Through the external threaded portion 33, the first clamping member 30 can be installed in a predetermined threaded hole and apply pressure to the clamping block 10 by threaded fastening to clamp the workpiece 500. Alternatively, the setting of the external threaded portion 33 can be eliminated, and other methods can be used to adjust the force on the clamping block 10. In one or more embodiments, the clamp 100 also includes a guide portion, which is used to guide the first clamping member 30 and the second clamping member 40 to move along the center line direction of the external threaded portion 33. Alternatively, the setting of the guide portion can also be eliminated. In one or more embodiments, the guide portion includes a first guide portion 34 provided on the first clamping member 30. The first guide portion 34 is configured as an annular flange 341 provided on the outer wall of the first clamping member 30. The annular flange 341 is spaced apart from the external threaded portion 33, and a thread backing groove is formed between the annular flange 341 and the external threaded portion 33 to facilitate the processing of the external threaded portion 33. The outer wall surface of the annular flange 341 is configured as a cylindrical surface, and the center line of the cylindrical surface coincides with the center line of the external threaded portion 33. Alternatively, the first guide portion 34 may also be configured in other suitable shapes.

[0035] Continue reading Figure 2 and Figure 3 In one or more embodiments, the second clamping member 40 is also configured as a substantially cylindrical body of revolution to facilitate processing and match with the first clamping member 30. Alternatively, the second clamping member 40 may also be configured into other suitable shapes according to actual needs. The second clamping member 40 includes a second accommodating groove 41, which is used to accommodate at least a portion of each second pressure-bearing portion 15. The second accommodating groove 41 includes a second opening 411 and a second circumferential wall 412. The second opening 411 faces the first opening 311, so that the second clamping member 40 and the first clamping member 30 can clamp the clamping block 10 together. The second circumferential wall 412 is the inner wall of the second accommodating groove 41. The second circumferential wall 412 is inclined toward the second opening 411, and the second pressure-bearing portion 15 can slide along the second circumferential wall 412. The second pressure-bearing portion 15 moves in two directions when sliding along the second circumferential wall 412, i.e., it moves toward the workpiece 500 and also moves toward the bottom of the second receiving groove 41 opposite to the second opening 411, so that when the first clamping member 30 and the second clamping member 40 approach each other, the first pressure-bearing portion 14 moves toward the bottom of the first receiving groove 31 and also moves toward the workpiece 500 placed in the middle of the plurality of clamping blocks 10. Similarly, the second pressure-bearing portion 15 moves toward the bottom of the second receiving groove 41 and also moves toward the workpiece 500. Therefore, both ends of each clamping block 10 are subjected to the force to move toward the workpiece 500, so that each clamping block 10 can synchronously squeeze the workpiece 500 at multiple points to ensure the honing accuracy.

[0036] In one or more embodiments, the second clamping member 40 includes a stop surface 42 and a connecting portion 43. The second opening 411 is formed on the stop surface 42, and the connecting portion 43 is also arranged on the stop surface 42 and protrudes outward from the stop surface 42 to form a substantially cylindrical shape. The connecting portion 43 surrounds the outer side of the second opening 411, and an internal thread portion 44 is provided on the inner wall of the connecting portion 43. The internal thread portion 44 matches the external thread portion 33, including but not limited to the center lines of the two coinciding, so that a threaded connection can be formed between the second clamping member 40 and the first clamping member 30, so that the two can be controlled to move toward or away from each other through the thread, and it is also convenient to control the clamping force applied by the first clamping member 30 and the second clamping member 40 to the clamping block 10. In an alternative embodiment, the first clamping member 30 and the second clamping member 40 can also form a sliding connection between them by other suitable means, such as a snap connection, so as to control the magnitude of the clamping force when the first clamping member 30 and the second clamping member 40 are close to each other.

[0037] In one or more embodiments, on the stop surface 42, the connection portion 43 is at a predetermined distance from the second opening 411, so that after the first clamping member 30 moves a certain distance toward the second clamping member 40 through the thread, it stops moving under the obstruction of the stop surface 42, and at this time, the maximum pressing stroke of the clamp 100 of this size is reached. If the workpiece 500 still cannot be pressed after reaching the maximum pressing stroke, the clamp 100 of another appropriate size should be replaced.

[0038] Continue reading Figure 3 In one or more embodiments, the guide portion further includes a second guide portion 45 disposed on the inner wall of the connecting portion 43. In one or more embodiments, the second guide portion 45 is configured as a guide groove 451. The structure of the guide groove 451 matches the annular flange 341. For example, the inner wall surface of the guide groove 451 is also configured as a cylindrical surface, and the center line of the cylindrical surface coincides with the center line of the internal thread portion 44, so that at least part of the annular flange 341 is accommodated in the guide groove 451 and can move along the center line direction of the cylindrical surface. Alternatively, the guide portion can also be configured as other suitable structures to guide the first clamping member 30 and the second clamping member 40 to approach or move away from each other along the center line direction of the external thread portion 33. In one or more embodiments, the outer wall surface of the annular flange 341 and the inner wall surface of the guide groove 451 form a clearance fit, so that the rotation between the first clamping member 30 and the second clamping member 40 generated by the thread is relatively smooth, and at the same time, the guide portion can still ensure that the first clamping member 30 and the second clamping member 40 move approximately along the center line direction of the external thread portion 33.

[0039] Continue reading Figure 2 and Figure 3In one or more embodiments, a connection plate 46 is provided on the outer wall of the second clamping member 40. The connection plate 46 is suitable for forming a fixed connection with a predetermined honing device, and the connection method includes but is not limited to screw connection, clamping connection, etc. Alternatively, the connection plate 46 can be eliminated or set at other suitable positions of the fixture 100.

[0040] The utility model also provides a honing device, which comprises the fixture 100 for the honing device.

[0041] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
