DETAILED DESCRIPTION

[0033] The technical solution of the present invention is further described below in conjunction with specific embodiments and drawings.

[0034] See also Figure 1-3 As shown, this embodiment provides a processing device for wrench jaws, which is used for fully automatic and high-precision processing of movable wrench jaws 29, including a frame 1, a material dividing mechanism, a feeding mechanism, a clamping mechanism, a first processing mechanism and a second processing mechanism arranged on the frame 1.

[0035] See also Figure 2 As shown, the first processing mechanism, the clamping mechanism, and the second processing mechanism are arranged along the left and right directions (i.e. Figure 2 The clamping mechanism and the feeding mechanism are arranged in a spaced manner along the front-to-back direction (i.e. Figure 2 The two axes are arranged alternately in the up and down directions.

[0036] The first processing mechanism is used for milling out the mouth surface 291 of the workpiece (referring to the wrench jaws 29, the same below); the second processing mechanism is used for synchronously milling out the tooth surface 293 and the teeth 292 of the workpiece.

[0037] The above-mentioned material distribution mechanism includes a first vibration plate 20 arranged on the frame 1, and a first material discharge channel 21 having one end connected to the first vibration plate 20. Through the vibration of the first vibration plate 20, the workpieces enter the first material discharge channel 21 one by one. The first material discharge channel 21 is arranged obliquely to enable the workpieces to slide under the action of gravity. The bottom end (i.e., the material discharge end) of the first material discharge channel 21 is a discharge end 211, which extends in the horizontal direction and has a certain length, and can prevent the workpieces from sliding out.

[0038] The feeding mechanism comprises a first mounting seat 2 arranged on the frame 1, a first driving assembly 3 arranged on the first mounting seat 2 and a linear guide rail 4, see Figure 2 As shown, the linear guide rail 4 is along the front-to-back direction (i.e. Figure 2 The first drive assembly 3 is a drive cylinder and is arranged on the right side of the linear guide rail 4. A clamping seat 5 is slidably arranged on the linear guide rail 4. The clamping seat 5 is provided with a cavity for accommodating a workpiece. The cavity passes through the clamping seat 5 in the left-right direction. The top of the cavity is provided with an opening that passes through the top and bottom and is connected to the left and right, which is used to suspend the workpiece and allow the workpiece to move left and right therein. The first mounting seat 2 is also provided with a second drive assembly 6 located below the discharge end 211 of the first material discharge channel 21. The second drive assembly 6 is a drive cylinder and is used to push the workpiece in the discharge end 211 into the clamping seat 5.

[0039] The above-mentioned first processing mechanism includes a second mounting seat 7 arranged on the frame 1, a first sliding seat 8 arranged on the second mounting seat 7 and slidable in a direction parallel to the linear guide rail 4, a first processing component 9 arranged on the first sliding seat 8, a servo drive component 10 and a first material receiving seat 11.

[0040] See also Figure 2 As shown, the first drive assembly 3 is located on the right side of the linear guide rail 4, and the first processing mechanism is located on the left side of the linear guide rail 4. When the first receiving seat 11 and the clamping seat 5 slide to align with the first drive assembly 3, the first drive assembly 3 pushes the workpiece in the clamping seat 5 to the left and pushes it into the first receiving seat 11. In this embodiment, the first processing assembly 9, the servo drive assembly 10 and the first receiving seat 11 slide synchronously.

[0041] In this embodiment, there are two groups of servo drive components 10, each group of servo drive components 10 includes a fifth mounting seat 101 arranged on the first sliding seat 8, a transmission chain arranged on the fifth mounting seat 101, a servo motor 102 arranged on the fifth mounting seat 101 and used to drive the transmission chain, and a first push rod 103 connected to the top of the transmission chain. The movement direction of the first push rod 103 is parallel to the horizontal plane and perpendicular to the linear guide rail 4. Figure 2 As shown, the first group of servo drive components 10, the first processing component 9, and the second group of servo drive components 10 are arranged in the front-to-back direction (i.e. Figure 2 The first material receiving seat 11 is arranged at the right end of the second group of servo drive components 10 at the rear.

[0042] See also Figure 2 As shown, the first processing assembly 9 includes a milling cutter 91 rotatable around its own axis and disposed on a first sliding seat 8 , and a first motor 92 for driving the milling cutter 91 to rotate, wherein the axis of the milling cutter 91 is perpendicular to the linear guide rail 4 .

[0043] The second processing mechanism includes a vertical axis (i.e. Figure 2 The third mounting seat 12 is provided on the frame 1 and is rotatable (in a direction perpendicular to the paper surface), the second sliding seat 13 is provided on the third mounting seat 12 and is slidable in a horizontal straight line direction, and the second processing assembly is provided on the second sliding seat 13. Since different workpieces have different requirements for the inclination angle of the teeth 292, the third mounting seat 12 is rotatable to meet the processing of workpieces with different requirements.

[0044] See also Figure 2 As shown, the second processing mechanism further includes a lifting seat 19 which is liftable and arranged on the second sliding seat 13, and the second processing assembly includes a first broach 14 which is arranged at the bottom of the lifting seat 19 and whose bottom surface is inclined up and down along the sliding direction of the second sliding seat 13. The first broach 14 is used for milling the teeth 292 and the tooth surface 293 at the same time, which not only improves the processing efficiency, but also avoids the problem of matching accuracy between the teeth 292 and the tooth surface 293 when they are milled separately. Since the bottom surface of the first broach 14 extends obliquely, when the second sliding seat 13 slides, the first broach 14 processes the workpiece from shallow to deep, which not only helps the workpiece to be processed and formed, but also reduces the wear of the first broach 14 and increases the service life of the first broach 14. By setting the lifting seat 19, workpieces of different heights can be processed.

[0045] The clamping mechanism comprises a fourth mounting seat 15 disposed on the frame 1 and located between the first processing mechanism and the second processing mechanism, and a first clamping assembly 16 and a second clamping assembly 17 disposed on the fourth mounting seat 15 and arranged in sequence along a direction perpendicular to the linear guide rail 4 .

[0046] See also Figure 2 As shown, the first clamping assembly 16 and the second clamping assembly 17 are arranged in the left-right direction, the first clamping assembly 16 is arranged on the first processing mechanism side, and the second clamping assembly 17 is arranged on the second processing mechanism side.

[0047] The first clamping assembly 16 includes a pair of first clamping blocks 161 that can slide toward or away from each other, and a first driving cylinder 162 for driving the pair of first clamping blocks 161 to move synchronously. The pair of first clamping blocks 161 are arranged in the front-to-back direction (i.e. Figure 2 The two axes are arranged alternately in the up and down directions.

[0048] The second clamping assembly 17 includes a pair of second clamping blocks 171 that can slide toward or away from each other, and a second driving cylinder 172 for driving the pair of second clamping blocks 171 to move synchronously. Figure 2 The two axes are arranged alternately in the up and down directions.

[0049] The clamping center lines of the pair of first clamping blocks 161 and the clamping center lines of the pair of second clamping blocks 171 coincide with each other and are perpendicular to the linear guide rail 4 .

[0050] When the workpiece is in the clamping seat 5, the first material receiving seat 11, the first clamping assembly 16 and the second clamping assembly 17, its tooth surface 293 faces upward and is hung therein, and its top end is higher than the top ends of the clamping seat 5, the first material receiving seat 11, the first clamping assembly 16 and the second clamping assembly 17 respectively.

[0051] The second servo drive assembly 10 is used to push the workpiece in the first receiving seat 11 into the first clamping assembly 16 so that the first processing mechanism can process the workpiece in the first clamping assembly 16 .

[0052] The first servo drive assembly 10 is used to push the workpiece processed in the first clamping assembly 16 into the second clamping assembly 17 , so that the second processing mechanism can process the workpiece in the second clamping assembly 17 .

[0053] Since both sets of servo drive components 10 are driven by the servo motor 102 , the workpiece can be accurately pushed to the set position, greatly improving the processing accuracy.

[0054] By providing two groups of servo drive components 10, processing time can be saved and processing efficiency can be improved.

[0055] The second processing mechanism further includes a third driving assembly 18 disposed on the second sliding seat 13, and the second clamping assembly 17 includes a retractable stopper (not shown in the figure) extending into the clamping groove thereof, and a third driving cylinder 173 disposed on one of the second clamping blocks 171 and used for driving the stopper to retract. The third driving assembly 18 is a driving cylinder that slides synchronously with the second processing assembly.

[0056] See also Figure 2 As shown, when the first servo drive assembly 10 drives the workpiece to the right to enter the second clamping assembly 17, the third drive cylinder 173 drives the limit member to retract to make way; then the third drive cylinder 173 drives the limit member to extend, and the third drive assembly 18 pushes the workpiece back to the left to make it contact with the limit member, so as to further accurately position the workpiece.

[0057] By setting the relative positions of the feeding mechanism, the clamping mechanism, the first processing mechanism and the second processing mechanism, when the second processing mechanism mills the tooth 292 and the tooth surface 293, the first processing mechanism is used to cooperate with the feeding mechanism to feed another workpiece, and to mill the mouth surface 291. By setting the feeding stroke, the first processing mechanism and the second processing mechanism can complete the separate processing of the two workpieces at the same time, thereby reducing the waiting time and greatly improving the processing efficiency.

[0058] See also Figure 1 As shown, in this embodiment, the above-mentioned processing device for the wrench jaws also includes a second vibration plate 22 arranged on the frame 1, and a second feeding channel 23 connected to the second vibration plate 22 at one end. The second feeding channel 23 is inclined to enable the workpiece to slide under the action of gravity.

[0059] The frame 1 is provided with a sixth mounting seat 24, on which a movable second material receiving seat 25 and a fixed material discharge trough 26 are provided. The second material receiving seat 25 is used to receive the workpiece output from the other end of the second material discharge channel 23 and transport it to the top of the material discharge trough 26. The workpiece in the second material receiving seat 25 is pushed downward into the material discharge trough 26 by the lifting second push rod 27. Since the material discharge trough 26 is provided with a second broach (not shown in the figure), the workpiece is milled with a small shoulder 294 by the second broach during the downward movement. The material discharge end of the second material discharge channel 23 is located above the movement path of the second material receiving seat 25, and the material discharge trough 26 is located below the movement path of the second material receiving seat 25.

[0060] The bottom of the material discharge chute 26 is connected to the material distribution mechanism through the feeding channel 28 . The workpiece pushed to the bottom of the material discharge chute 26 by the second push rod 27 enters the first vibration plate 20 through the feeding channel 28 after being completely processed by the second broach.

[0061] The working process of this embodiment is described in detail below:

[0062] S1: The second vibration plate 22 drops the workpiece onto the second material receiving seat 25 through the second material discharge channel 23. The second material receiving seat 25 then moves to above the material discharge trough 26. The second push rod 27 pushes the workpiece downward into the material discharge trough 26. The second broach mills a small shoulder 294 on the workpiece.

[0063] S2: The workpiece climbs up to the first vibration plate 20 through the feeding channel 28, slides down to the discharge end 211 through the first discharge channel 21, and after the clamping seat 5 moves to align with the discharge end 211, the second driving assembly 6 pushes the workpiece at the discharge end 211 into the clamping seat 5;

[0064] S3: The clamping seat 5 and the second group of servo drive components 10 move to align with the first drive component 3 respectively, and the first drive component 3 pushes the workpiece in the clamping seat 5 into the first receiving seat 11;

[0065] S4: The second servo drive assembly 10 moves to align with the first clamping assembly 16, and the servo motor 102 drives the first push rod 103 to extend, and pushes the workpiece in the first receiving seat 11 into the first clamping assembly 16. After it is in place, the first drive cylinder 162 drives the two first clamping blocks 161 to clamp the workpiece, and the first processing assembly 9 moves to align with the workpiece, and the milling cutter 91 is used to mill the workpiece surface 291;

[0066] S5: After the processing is completed, the first group of servo drive components 10 moves to align with the first clamping component 16, the first clamping component 16 releases the workpiece, the third drive cylinder 173 drives the limit piece to retract, and the servo motor 102 drives the first push rod 103 to extend, and push the workpiece in the first clamping component 16 into the second clamping component 17, and then the third drive cylinder 173 drives the limit piece to extend, and the third drive component 18 pushes the workpiece back to the limit piece, and adjusts the angle between the first broach 14 and the workpiece through the third mounting seat 12, and then the first broach 14 mills the teeth 292 and the tooth surface 293 of the workpiece.
