[0030] A fixture is a process device used during machining to quickly secure the workpiece and maintain the correct relative position of the machine tool, cutting tool, and workpiece. In other words, tooling fixtures are indispensable components of machining. Driven by the development of machine tool technology towards high speed, high efficiency, precision, composite, intelligent, and environmentally friendly directions, fixture technology is developing towards high precision, high efficiency, modularity, combination, versatility, and economy. However, existing fixtures suffer from poor fixing effects.
[0031] Based on the above problems, the blocking side and the top surface of the support in this embodiment can not only increase the contact area between the fixture and the workpiece, but also restrict the horizontal movement of the workpiece through the combination of the positioning part and the connecting part; the first fixing component can restrict the vertical movement of the workpiece by pressing the workpiece against the top surface of the support platform; thereby improving the positioning effect of the workpiece.
[0032] Figure 1 The diagram shown is a schematic diagram of workpiece 10 in an embodiment of this disclosure. Figure 2 The diagram shown is a schematic representation of the overall structure of the machining fixture in an embodiment of this disclosure. Figure 3 The diagram shown is a top view of the overall structure of the machining fixture in an embodiment of this disclosure. Figure 1 , Figure 2 and Figure 3 In the example, the workpiece 10 has a cavity 101 and a connecting portion 102. The machining fixture includes a support platform 20 and a first fixing assembly 30. The support platform 20 includes a support portion 21 for insertion into the cavity 101 and at least one positioning portion 22; the support portion 21 has at least one stopping side surface 211 that stops and engages with the side wall of the cavity 101, and at least one supporting top surface 212 that abuts against the top wall of the cavity 101; the at least one positioning portion 22 is concave-convexly fitted to the connecting portion 102. The first fixing assembly 30 is disposed on the support platform 20; the first fixing assembly 30 includes at least one clamping member 31 to press the workpiece 10 against the top surface of the support platform 20 after the workpiece 10 is engaged with the support portion 21 and the positioning portion 22.
[0033] The advantages of the above configuration are that the blocking side 211 and the supporting top surface 212 of the support part 21 can not only increase the contact area between the fixture and the workpiece 10, but also restrict the horizontal movement of the workpiece 10 through the concave-convex cooperation of the positioning part 22 and the connecting part 102; the first fixing component 30 can restrict the vertical movement of the workpiece 10 by pressing the workpiece 10 against the top surface of the support platform 20; thereby improving the positioning effect of the workpiece 10.
[0034] For example, the axis of the support portion 21 is not coaxial with the axis of the positioning portion 22. In this way, the workpiece 10 can be prevented from rotating during processing due to the coaxiality of the support portion 21 and the positioning portion 22, thereby ensuring the processing accuracy and pass rate of the workpiece 10.
[0035] Exemplarily, one of the connecting portion 102 and the positioning portion 22 is implemented as a hole, and the other is implemented as a post that engages with the hole. In this embodiment, the connecting portion 102 is implemented as a connecting hole, and the positioning portion is implemented as a positioning pin inserted into the connecting hole. In another embodiment, the connecting portion 102 is implemented as a connecting pin, and the positioning portion 22 is implemented as a positioning hole that engages with the connecting pin.
[0036] In this embodiment, the blocking side surface 211 can be implemented as several spaced-apart arcuate surfaces. In another embodiment, the blocking side surface 211 can be implemented as a complete annular surface. When the blocking side surface 211 is implemented as a complete annular surface, the cross-sectional shape of the blocking side surface 211 matches the cross-sectional shape of the cavity 101. When the cavity 101 is an irregular shape, the blocking side surface 211 is implemented as several spaced-apart arcuate surfaces. In another embodiment, the blocking side surface 211 can be implemented as a plane or a curved surface.
[0037] exist Figure 2 In the example, the support portion 21 includes a support base 213 and a support column 214; the support base 213 is detachably disposed on the support platform 20, and the support column 214 is detachably disposed on the top wall of the support base 213; the stop side 211 is formed on the side wall of the support base 213, and the support top surface 212 is formed on the top wall of the support column 214. Exemplarily, the detachable connection is implemented as a screw connection or a snap-fit connection. This facilitates the operator in replacing or repairing damaged support columns 214 or those missing support top surfaces 212, thereby avoiding processing failures caused by damage to the support column 214 or the missing support top surfaces 212, and thus improving the pass rate of the workpiece 10.
[0038] exist Figure 2 and Figure 3 In this example, multiple support top surfaces 212 are implemented. These multiple support top surfaces 212 are evenly and spaced apart on the top surface of the support portion 21. That is, multiple support columns 214 are implemented.
[0039] For example, the clamping member 31 is configured such that when the workpiece 10 is picked up or placed, the clamping member 31 disengages from the workpiece 10 and avoids the workpiece 10 from approaching or moving away from the pick-up or place path of the support table 20. Figure 4The diagram shown is a cross-sectional view of the machining fixture in an embodiment of this disclosure. Figure 4 In the example, each clamping member 31 includes a connecting plate 311, a clamping plate 312, and a first telescopic member 313. The first telescopic member 313 is implemented as a hydraulic cylinder or a pneumatic cylinder. The clamping plate 312 includes a first clamping end 3121 and a first driving end 3122; one end of the connecting plate 311 is hinged to the support platform 20, and the other end is hinged between the first clamping end 3121 and the first driving end 3122; the output end of the top of the first telescopic member 313 is hinged to the first driving end 3122; wherein, when the output end of the first telescopic member 313 retracts, the first clamping end 3121 of the clamping plate 312 is driven to disengage from the workpiece 10 and avoid the workpiece 10 approaching or moving away from the pick-up and put-down path of the support platform 20.
[0040] Those skilled in the art will understand that when the first telescopic member 313 retracts, the first driving end 3122 of the clamping plate 312 is pulled downwards, causing the first clamping end 3121 of the clamping plate 312 to swing upwards. As the first telescopic member 313 continues to retract, the output end of the first telescopic member 313, via the clamping plate 312, drives the connecting plate 311 to swing away from the workpiece 10, thereby avoiding the path for picking up and placing the workpiece 10. The advantage of this arrangement is that it avoids the path for picking up and placing the workpiece 10, thus facilitating the operator's installation or removal of the workpiece 10 and improving the processing efficiency of the workpiece 10. When the first telescopic member 313 extends, the first clamping end 3121 of the clamping plate 312 performs the opposite steps, and therefore will not be described in detail here.
[0041] exist Figure 2 and Figure 3 In the example, the support platform 20 has a clamping area extending along a first direction; the clamping members 31 are implemented in two pairs; the two pairs of clamping members 31 are spaced apart along the first direction, and the support portion 21 is located between the two pairs of clamping members 31; two clamping members 31 in each pair are disposed opposite each other on adjacent sides of the first direction; wherein, when the workpiece 10 is engaged with the support portion 21, the two pairs of clamping members 21 press the workpiece 10 against the top surface of the support platform 20. For example, the two clamping members 31 located on the left side of the workpiece 10 are a pair, and the two clamping members 31 located on the right side of the workpiece 10 are a pair, and each clamping member 31 has the same structure. The advantage of this arrangement is that the even distribution of the two pairs of clamping members 31 can simultaneously press each part of the workpiece 10 against the support platform 20, avoiding tilting or other situations caused by uneven force on the workpiece 10.
[0042] In another embodiment, the clamping members 31 may also be implemented as a pair. The pair of clamping members 31 are symmetrically arranged; the support portion 21 is located between the pair of clamping members 31; and when the workpiece 10 is engaged with the support portion 21 and the positioning portion 22, the workpiece 10 is pressed against the top surface of the support platform 20.
[0043] exist Figure 2 and Figure 3 In the example, the machining fixture further includes a second fixing component 40 disposed on the support platform 20. The second fixing component 40 includes a stop block 41 and a clamping member 42; wherein, when the workpiece 10 is engaged with the support portion 21 and the positioning portion 22, the clamping member 42 clamps the workpiece 10 against the stop block 41.
[0044] Exemplarily, the stop block 41 is disposed on the support platform 20 and located on one side of the line connecting the support portion 21 and the positioning portion 22. The clamping member 42 includes a second telescopic member 421 and a pressing plate 422. The second telescopic member 421 is implemented as a hydraulic cylinder or a pneumatic cylinder. The pressing plate 422 includes a second clamping end 4221 and a second driving end 4222. The middle portion of the pressing plate 422 is hinged to the cylinder body of the second telescopic member 421, and the output end of the second telescopic member 421 is hinged to the second driving end 4222; wherein, when the output end of the second telescopic member 421 extends, the second clamping end 4221 of the pressing plate 422 applies a clamping force to the workpiece 10 in a direction close to the stop block 41, thereby preventing the workpiece 10 from loosening.
[0045] In summary, the embodiments of this disclosure provide a machining fixture and production equipment. The machining fixture includes a support platform and a first fixing component. The support platform includes a support portion for insertion into the cavity and at least one positioning portion; the positioning portion has at least one stopping side surface that stops and engages with the side wall of the cavity, and at least one supporting top surface that abuts against the top wall of the cavity; the at least one positioning portion is concave-convexly engaged with the connecting portion.
