Detailed Description
The technical solution of the present application will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1, the apparatus for turning threads on a substrate disclosed in the embodiment of the present application mainly includes a worktable 31, a cutting portion 32, a substrate 11, a first fixture 13, a second fixture 15, a telescopic device 21, a driving device 22, and the like, where two cutting portions 32 are installed on the worktable 31 and slidably connected to the worktable, and are used to cut threads at two ends of the substrate.
The base body 11 is fixedly mounted on the worktable 31 and located between the two cutting portions 32, and is provided with a through hole 12, and both ends of the through hole 12 are open ends and are responsible for mounting the first clamp body 13 and the second clamp body 15.
Referring to fig. 2 to 4, one end of the first fixture body 13 is inserted into the through hole 12, so that the first fixture body 13 can slide back and forth along the axial direction of the through hole 12 under the pushing of an external force. The first fixture body 13 is provided with a first positioning through hole 14, and the first positioning through hole 14 is used for positioning the drilling tool base body.
One end of the second clamp body 15 is also inserted into the through hole 12 and is slidably connected with the base body 11 through the through hole 12, and one end thereof is also slidably connected with the first clamp body 13, which has the function of ensuring the relative positional accuracy between the first clamp body 13 and the second clamp body 15.
It should be understood that there is an error in the processing of the through hole 12, and the error increases as the length of the through hole 12 increases, and if only the through hole 12 is used as a positioning reference, the relative position accuracy of the first clamp body 13 and the second clamp body 15 cannot be ensured, so that the first clamp body 13 and the second clamp body 15 need to be connected together by a sliding connection, so that the relative position relationship can be ensured during the movement of the two.
In some possible implementations, one end of the first clamp body 13 is inserted into the second positioning through hole 16 on the second clamp body 15 or one end of the second clamp body 15 is inserted into the first positioning through hole 14 of the first clamp body 13.
The minimum radius of curvature of the first locating through hole 14 and the second locating through hole 16 are equal, so that the drill base body can be conveniently located.
Since the number of the cutting portions 32 is two, simultaneous cutting can be performed, that is, the existing four steps are simplified into one step, and no error is accumulated in the entire machining process.
The drilling tool base body is clamped and rotated through the telescopic device 21 and the driving device 22, when the telescopic device 21 works, the first clamp body 13 and the second clamp body 15 are pulled to move towards the direction close to each other, in some possible implementation modes, the telescopic device 21 uses an air cylinder, a bearing is installed on the working end of the telescopic device, the bearing is clamped in a groove in the outer wall of the first clamp body 13, when the telescopic device 21 acts, the first clamp body 13 is pushed to move through the bearing, the moving mode of the second clamp body 15 is the same as that of the first clamp body, and the description is omitted here.
The driving device 22 is also mounted on the base 11 and functions to drive the first clamp body 13 and the second clamp body 15 to rotate, because after the first clamp body 13 and the second clamp body 15 clamp the drill base, only one of the first clamp body 13 and the second clamp body 15 is driven to rotate, and the other two clamp bodies rotate along with the rotation, therefore, the driving device 22 can drive the first clamp body 13 to rotate, can drive the second clamp body 15 to rotate, and certainly can also drive the drill base to rotate.
As for the manner of driving, a friction force may be used, for example, a friction wheel is mounted on the output shaft of the driving device 22, and the friction wheel abuts on the first clamp body 13 or the second clamp body 15.
Use the base member screw thread turning equipment that this application embodiment provided, can press from both sides the both ends of drilling tool base member simultaneously tightly, like this, just can carry out thread machining at both ends simultaneously, compare in the mode of changing anchor clamps and equipment behind the single thread machining before, it is very obvious, the precision of this kind of processing mode is higher because the change instrument in the middle of having saved has reduced the error accumulation.
It should be understood that in general thread machining, a three-jaw chuck is used for fixing, the three-jaw chuck can only fix one end of a drill base body, and sliding and shaking conditions are easy to occur in the machining process, and particularly, the sliding degree and the shaking degree are further increased along with the increase of the length of the drill base body.
The movement of the first and second clamp bodies 13, 15 is effected by means of a telescopic device 21, the telescopic device 21 being mounted on the base body 11,
the first clamp body 13 and the second clamp body 15 clamp the drilling tool base body in the process of approaching to each other, after machining is completed, the first clamp body 13 and the second clamp body 15 are far away from each other, and at the moment, the machined drilling tool base body can be taken out.
On the whole, the base body thread turning equipment provided by the embodiment of the application changes the machining mode of the base body of the drilling tool, changes the conventional single-head multiple machining into double-head synchronous machining, reduces the process steps and improves the machining precision. In the usage scenario of the multi-drill base connection, the stability of the multi-drill base connection during rotation is higher.
From another perspective, it can be understood that, because of the machining accuracy, the drill base machined with a single-head multiple-pass is used, when a plurality of drill bases are connected, the actual axis of the drill bases and the theoretical axis are not coincident, and the misalignment ratio is high, and when the double-head synchronous machining is used, the actual axis of the drill bases and the theoretical axis are not completely coincident, but the misalignment ratio is greatly reduced, so that the stability is higher during the rotation.
In one embodiment of the present application, a first tapered snap ring 17 is provided on an outer wall of the first clamp body 13, and a maximum outer diameter of the first tapered snap ring 17 is increased in a direction away from the base body 11, so that after the first tapered snap ring 17 contacts the base body 11, the base body 11 applies a pressure to the first clamp body 13 through the first tapered snap ring 17, so that a minimum radius of curvature of the first positioning through hole 14 is reduced, thereby clamping one end of the drill base body.
Similarly, a second conical snap ring 18 is arranged on the outer wall of the second clamp body 1, and the function of the second conical snap ring 18 is the same as that of the first conical snap ring 17, and details are not repeated here.
Referring to fig. 3, as an embodiment of the base threading device provided in the application, a plurality of first expansion joints 131 are added on the first fixture body 13, an axis of the first expansion joints 131 is parallel to an axis of the first fixture body 13, one end of the first expansion joints 131 is an open end, and the other end of the first expansion joints 131 is a closed end.
The first expansion joint 131 is used for increasing the deformation degree of the first fixture body 13 and improving the clamping effect of the drill base body.
It will be appreciated that the clamping force is the only force that will ensure that no relative sliding will occur between the drill base and the first clamp body 13 during machining, so the clamping effect will be better the greater the clamping force, but the increased clamping force will result in deformation of the drill base, so the use of a wrap-around clamping force is more appropriate, reducing the pressure per unit area by increasing the contact area.
After the contact area is increased, the deformation degree of the first clamp body 13 can be increased by increasing the first expansion joint 131, so that the clamping force can be further increased. It can be considered that after the first expansion joints 131 appear, the first fixture bodies 13 between the adjacent first expansion joints 131 are independent, and the deformation degree is larger under the action of pressure.
Referring to fig. 3, as an embodiment of the substrate threading device provided in the application, a plurality of second expansion joints 151 are added on the second fixture body 15, an axis of the second expansion joints 151 is parallel to an axis of the second fixture body 15, one end of the second expansion joints is an open end, and the other end is a closed end.
The function of the second expansion joint 151 is the same as that of the first expansion joint 131, and reference may be made to the above description, which is not repeated herein.
Referring to fig. 2, as an embodiment of the substrate thread turning apparatus provided in the application, a plurality of first through holes 132 are added to the first fixture body 13, the number of the first through holes 132 is the same as that of the first expansion joints 131, and each of the first through holes 132 is communicated with the closed end of the corresponding first expansion joint 131, so as to further improve the deformation degree of the first fixture body 13.
It should be understood that, the larger the width of the first fixture body 13 between two adjacent first expansion joints 131 is, the larger the pressure required for deformation is, after the first through holes 132 are added, the width of the first fixture body 13 between two adjacent first through holes 132 is reduced, and the pressure required for deformation is reduced, so that the first fixture body 13 is more easily deformed, and meanwhile, the contact area with the drilling tool base body is also ensured.
Referring to fig. 3, as a specific embodiment of the substrate thread turning device provided in the application, a plurality of second through holes 152 are also added to the second fixture body 15, the number of the second through holes 152 is the same as that of the second expansion joints 151, and each second through hole 152 is communicated with the closed end of the corresponding second expansion joint 151, which also has an effect of further improving the deformation degree of the first fixture body 13.
Referring to fig. 2 and 3, as an embodiment of the substrate thread turning apparatus provided by the application, a first arc-shaped block 141 is provided on an inner wall of the first positioning through hole 14, and a second arc-shaped block 142 is added on an inner wall of the second positioning through hole 16, and the first arc-shaped block 141 and the second arc-shaped block 142 are used for contacting with the drill substrate and applying pressure to the drill substrate.
The number of the first arc-shaped blocks 141 is the same as that of the first expansion joints 131, and one first arc-shaped block 141 is arranged between any two adjacent first expansion joints 131; the number of the second arc-shaped blocks 142 is the same as that of the second expansion joints 151, and one second arc-shaped block 142 is arranged between any two adjacent second expansion joints 151.
In addition, the minimum radius of curvature of the first arc-shaped block 141 is equal to the minimum radius of curvature of the second arc-shaped block 142, and the minimum radius of curvature of the first arc-shaped block 141 is smaller than the minimum radius of curvature of the first positioning through-hole 14.
After first arc piece 141 and second arc piece 142 appear, first locating through-hole 14 just no longer contacts with the drilling tool base member with second locating through-hole 16, from the angle of processing consideration, and the required work load will descend, and is corresponding, and the precision during processing also can improve, because compare in processing first locating through-hole 14 and second locating through-hole 16, it is obviously easier to the processing of first arc piece 141 and second arc piece 142, and the machining precision is also controlled more easily.
Referring to fig. 5, it should be understood that the control of the cutting portion 32, the retracting device 21 and the driving device 22 can be performed by the controller 6, and the controller 6 stores corresponding programs capable of controlling the cutting portion 32, the retracting device 21 and the driving device 22 to perform corresponding actions according to a set sequence.
