Description

Background

In the processing process of parts of a photovoltaic production line, the processing surfaces of some parts have a certain inclination angle relative to other surfaces, and when the parts are processed by adopting a conventional clamping and processing technology, the processed surfaces of the parts have defects.

Example 1

The embodiment of the disclosure provides a clamp, which comprises a bearing seat 1, a first positioning block 2, a second positioning block 3, a second positioning block 311 and a sliding component, wherein the bearing seat 1 is provided with a bearing surface 11, the bearing surface 11 is an inclined surface, the first positioning block 2 is arranged on the bearing surface 11 and is provided with a first clamping part 211, the second positioning block 3 is arranged on the bearing surface 11 in a first direction A and is opposite to the first positioning block 2, the second positioning block 3 is provided with a second clamping part 311 opposite to the first clamping part 211, a clamping space 4 is formed between the first clamping part 211 and the second clamping part 311, the first clamping part 211 and the second clamping part 311 have a height difference in a second direction B, the second positioning block 3 can slide relative to the bearing surface 11 along the first direction A through the sliding component so as to adjust the size of the clamping space 4, and the second direction B is perpendicular to the first direction A.

Specifically, as shown in fig. 1 to 5, the bearing seat 1 is used for bearing the first positioning block 2, the second positioning block 3 and the sliding component. The bearing seat 1 is provided with a bearing surface 11, the bearing surface 11 is an inclined surface, namely, the bearing surface 11 forms an included angle with a horizontal plane, and the horizontal plane can be an operation table top. The included angle between the bearing surface 11 and the horizontal plane is not specifically limited, and may be set according to actual needs, and the extension length of the bearing surface 11 may also be set according to actual needs. The first positioning block 2 is arranged on the bearing surface 11, the first positioning block 2 can be detachably fixed on the bearing surface 11, and the position of the first positioning block 2 relative to the bearing surface 11 can be adjusted at any time according to the requirement. The first positioning block 2 may be any shape, such as a cuboid, a cube, etc. The first clamping portion 211 of the first positioning block 2 may be a clamping surface, to-be-clamped piece 15 implements surface clamping, or the first clamping portion 211 of the first positioning block 2 is a clamping column, to-be-clamped piece 15 implements line clamping or point clamping.

The second positioning block 3 is opposite to the first positioning block 2 along the first direction a, the second positioning block 3 has a second clamping portion 311 opposite to the first clamping portion 211, the second clamping portion 311 may be a clamping surface, and the workpiece 15 is clamped by a surface, or the second clamping portion 311 of the second positioning block 3 is a clamping column, and the workpiece 15 is clamped by a line or a point. The second positioning block 3 may be any shape, such as a cuboid, a cube, etc. The second positioning block 3 can slide relative to the bearing surface 11 along the first direction a by a sliding assembly so as to adapt to the clamping pieces 15 with different sizes. Since the bearing surface 11 is an inclined surface, the first clamping portion 211 of the first positioning block 2 and the second clamping portion 311 of the second positioning block 3 have a height difference in the second direction B, and the position of the first positioning block 2 relative to the bearing surface 11 can be adjusted as required at any time. In addition, by adjusting the positions of the first positioning block 2 and the second positioning block 3 relative to the bearing surface 11, the height difference between the first clamping portion 211 and the second clamping portion 311 can be adjusted so as to adapt to the to-be-clamped pieces 15 having different inclined planes.

The sliding assembly may include a linear slide rail and a slider, and the combination of the linear slide rail and the slider may allow the second positioning member 9 to move smoothly along a predetermined direction, or may further include a screw nut mechanism, which drives a nut engaged with the screw to move by rotating the screw, thereby driving the second positioning block 3 to move linearly, or may use a gear to engage with a fixedly installed rack, and realize linear movement of the second positioning block 3 by rotating the gear.

The fixture and the machine tool provided by the disclosure comprise a bearing seat 1, a first positioning block 2, a second positioning block 3 and a sliding assembly. When machining a part having a bevel, an operator places the part to be machined in the clamping space 4. The distance between the second positioning block 3 and the first positioning block 2 is adjusted through the sliding assembly so as to adapt to the size of the part to be machined. Because the bearing surface 11 is an inclined surface, the first clamping part 211 of the first positioning block 2 and the second clamping part 311 of the second positioning block 3 generate a height difference, so that the inclination of the part to be processed is compensated, and the inclined surface of the part to be processed is converted into a horizontal surface parallel to a machine tool workbench.

In some embodiments, the sliding assembly comprises a sliding groove 51 extending along a first direction A, a sliding block provided on the second positioning block 3 and adapted to the sliding groove 51 so as to enable the second positioning block 3 to be slidingly connected to the carrying surface 11, and an adjusting rod 52 extending along the first direction A, one end of which is connected to the second positioning block 3 and the other end of which is rotatably connected to the carrying seat 1, so that the adjusting rod 52 can slide along the first direction A relative to the carrying seat 1.

Specifically, as shown in fig. 1, the chute 51 may extend along the first direction a, and the length thereof may be set according to actual needs. The number of the sliding grooves 51 may be one or more, and when the number of the sliding grooves 51 is plural, the plurality of sliding grooves 51 may be disposed at intervals in the third direction C. The sliding groove 51 may be a T-shaped groove, and the sliding block may be a sliding block adapted to the sliding groove 51, such as a T-shaped bolt. The provision of the T-shaped chute 51 allows easy insertion and removal of T-bolts or other accessories, and allows adjustment and reconfiguration of the second positioning block 3 without damaging the overall structure. One end of the adjusting rod 52 is connected to the second positioning block 3, and the other end is connected to the bearing seat 1 by means of a rotational connection, in addition, the adjusting rod 52 can be in threaded connection with the bearing seat 1, when the position of the second positioning block 3 needs to be adjusted, the adjusting rod 52 can be rotated manually or mechanically, so that the adjusting rod 52 rotates relative to the bearing seat 1 and slides along the first direction a to push the second positioning block 3 connected with the adjusting rod to slide along the sliding groove 51. The sliding assembly not only improves the operation convenience and flexibility of the clamp, but also improves the processing quality and the production efficiency through the accurate positioning capability and the stable clamping effect.

In some embodiments, the device further comprises a guide rod 6 embedded in the bearing surface 11 along the first direction A, wherein the guide rod 6 penetrates through the first positioning block 2 and the bearing seat 1, and an elastic piece 7 stretches and contracts along the first direction A, is sleeved on the guide rod 6, and has one end propped against the first positioning block 2 and the other end propped against the second positioning block 3.

Specifically, as shown in fig. 3, in order to make the first positioning block 2 be more stably fixed on the bearing seat 1, the fixture further includes a guide rod 6, the guide rod 6 extends along the first direction a and is embedded in the bearing surface 11, and the guide rod 6 penetrates through the first positioning block 2 and the bearing seat 1 to fix the first positioning block 2 and the bearing seat 1 together. In addition, the first clamping portion 211 of the first positioning block 2 is located at an end of the first positioning block 2 away from the bearing surface 11, the second clamping portion 311 of the second positioning block 3 is located at an end of the second positioning block 3 away from the bearing surface 11, and when the first positioning block 2 and the second positioning block 3 clamp the workpiece 15 to be clamped, the workpiece 15 to be clamped is located at an end of the first positioning block 2 and the second positioning block 3 away from the bearing surface 11. In order to prevent the first positioning block 2 and the second positioning block 3 from contracting relatively when clamping the to-be-clamped piece 15 due to uneven stress, one sides of the first positioning block 2 and the second positioning block 3 close to the bearing surface 11 are away from each other, and one sides of the first positioning block 2 and the second positioning block 3 away from the bearing surface 11 are away from each other, so that the clamping force for clamping the to-be-clamped piece 15 is uneven, an elastic piece 7 is sleeved on the guide rod 6, the elastic piece 7 extends along the first direction A, one section of the elastic piece is propped against the first positioning block 2, and the other end of the elastic piece is propped against the second positioning block 3. By sleeving the guide rod 6 with an elastic member 7 (such as a spring), a pre-tightening force can be provided between the first positioning block 2 and the second positioning block 3. When clamping the to-be-clamped piece 15, the elastic piece 7 can provide a uniform reverse force to help balance the external force applied to the positioning block and prevent the deformation or displacement of the positioning block caused by uneven stress. In addition, the presence of the elastic element 7 gives the clamp a certain self-adapting capacity. When the size of the to-be-clamped piece 15 changes, the elastic piece 7 can automatically adjust the compression degree of the to-be-clamped piece to adapt to different clamping requirements, so that the stability of the clamping force is maintained.

Specifically, as shown in fig. 1, the first spacer 21 may have a height higher than the first positioning block 2 or lower than the first positioning block 2, and the second spacer 31 may have a height higher than the second positioning block 3 or lower than the second positioning block 3. When the size of the workpiece 15 to be clamped is small, in order to prevent the first positioning block 2 and the second positioning block 3 from being damaged by a tool being processed when the workpiece 15 to be clamped is processed, the first spacer 21 is higher in height than the first positioning block 2, and the second spacer 31 is higher in height than the second positioning block 3. The provision of the first and second shims 21, 31 increases the contact area between the first and second positioning blocks 2, 3 and the bearing surface 11, thereby improving the stability of the overall clamping system. The use of the first and second shims 21, 31 helps to distribute the pressure, reduce localized stress concentrations, and make the clamping more secure. The first clamping portion 211 and the second clamping portion 311 are designed as L-shaped grooves, which can provide better positioning and clamping effects. The L-shaped groove can be better adapted to different shapes and sizes of the to-be-clamped piece 15, and multidirectional support is provided, so that the clamping precision is improved. The L-shaped grooves make it easier to align the members 15 to be clamped, and in particular, provide better guiding in the case of positioning in multiple directions.

In some embodiments, the side of the first positioning block 2 near the bearing surface 11 extends out of the protruding portion 22, and the bearing surface 11 is provided with a groove adapted to the protruding portion 22, so that the protruding portion 22 is embedded in the bearing seat 1.

The bearing surface 11 is provided with a groove adapted to the projection 22, in which groove the projection 22 is embedded, and further, the fixing of the first positioning block 2 to the bearing seat 1 can be enhanced by penetrating the projection 22 and the bearing seat 1 through the guide rod 6. The protruding part 22 is matched with the groove of the bearing surface 11, so that the first positioning block 2 can be effectively prevented from being displaced or loosened due to the action of external force in the clamping process, the stability in the processing process is ensured, the contact area between the first positioning block 2 and the bearing surface 11 is increased, the rigidity of the integral structure is enhanced, and the deformation resistance is improved.

The first locking portion and the first locking member may be engaged with each other by a recess and a protrusion, for example, the first positioning block 2 has a recess, and the first spacer 21 has a corresponding protrusion. During installation, the bulge is inserted into the groove, and then the gasket is fixed on the positioning block by lightly rotating or pressing. The first locking part and the first locking part can be in threaded connection, for example, a threaded hole is formed in the first positioning block 2, and a threaded column or a bolt matched with the threaded hole is formed in the first gasket 21. The second locking part has the same structure as the first locking part, and the second locking member has the same structure as the first locking member, and a repeated explanation is omitted.

In some embodiments, the connecting piece 8 is rotatably disposed at one side of the first positioning block 2, and the connecting piece 8 is provided with a fixing portion, the positioning piece 9 extends along a third direction C and is detachably connected to the fixing portion, one end of the positioning piece 9, which is away from the fixing portion, is a positioning portion for abutting against the to-be-clamped piece 15, and the third direction C is perpendicular to the second direction B and the first direction a.

When the clamp clamps the small-sized piece 15 to be clamped, the positioning piece 9 can abut against one end of the piece 15 to be clamped along the third direction C.

In some embodiments, the bearing seat 1 comprises a base 12, a supporting portion 13 extending along a second direction B, and a bearing plate 14 disposed on the base 12, wherein one end of the bearing plate 14 is supported on the base 12 through the supporting portion 13, so that the bearing plate 14 forms a height difference along the first direction a, and the supporting portion 13 can stretch and retract along the second direction B to adjust the height difference along the two ends of the bearing plate 14.

Specifically, as shown in fig. 1, the base 12 is a basic part of the carrying seat 1 for fixing the entire structure and providing support. The base 12 may be a planar or shaped structure to accommodate different mounting environments. The supporting portion 13 is a structure extending in the second direction B for supporting one end of the carrier plate 14. The support 13 is designed to allow it to telescope in the second direction B to adjust the height difference across the carrier plate 14. The supporting part 13 may employ various telescopic mechanisms such as a telescopic rod to implement the telescopic of the supporting part 13, a length adjustment of the telescopic rod to change the inclination angle of the supporting plate 14, a hydraulic cylinder or an air cylinder to implement the telescopic of the supporting part 13, a hydraulic or pneumatic control system to adjust the inclination angle of the supporting plate 14, a screw elevating mechanism to adjust the height of the supporting plate 14 by rotating a handle or a motor, etc. The carrying plate 14 is disposed on the base 12, one end of which is supported by the supporting portion 13, and the other end of which is directly placed on the base 12. The design of the carrier plate 14 needs to ensure that it can withstand the weight of the first and second positioning blocks 2 and 3 and the piece 15 to be clamped and can remain stable when the height difference is adjusted. By adjusting the telescopic length of the supporting portion 13, the height difference of both ends of the loading plate 14 can be changed. When the supporting portion 13 is extended, one end of the loading plate 14 is raised, and when the supporting portion 13 is shortened, one end of the loading plate 14 is lowered. The height difference of the carrier plate 14 is adjusted according to workpieces of different sizes. By using a telescopic rod or a hydraulic cylinder as the supporting portion 13, the height of the carrier plate 14 can be conveniently adjusted to accommodate workpieces having different slope sizes. This design not only improves the flexibility of the clamping, but also ensures stability and accuracy in the clamping process.

In some embodiments, the base 12 is provided with a U-shaped securing aperture 10.

Specifically, as shown in fig. 1 to 5, when the jig is fixed to a machine tool, a U-shaped fixing hole 10 is provided in a base 12 in order to facilitate adjustment of the position of the jig with respect to the machine tool. The U-shaped fixing holes 10 can be positioned quickly during installation, and the fixing bolts only need to penetrate through the U-shaped fixing holes 10 without accurately aligning with hole positions.
