[0002] In order to facilitate the installation of the front spring pressure plate (referred to as front spring pressure plate), the connecting hole of the front spring pressure plate needs to be processed during processing, and the two end faces of the connecting hole need to be processed. The shape of the front spring pressure plate is irregular, and the multiple end faces of the connecting hole need to be processed by turning up and down. Manual labor intensity is large, and it needs to be aligned and processed. It takes a long time and has low processing efficiency. The outer side end face of each connecting hole is easy to be processed during processing. The inner side end face of the connecting hole cannot be directly penetrated by the drill bit. Generally, the drill bit needs to be disassembled, the connecting shaft of the drill bit is inserted into one of the connecting holes, and then the drill bit is installed for processing. The distance between the two connecting holes is small, which makes it difficult to install the drill bit, and the operation is complex, and there is a safety hazard. In view of this, the countersinking machine for the front spring pressure plate is designed. SUMMARY

[0003] The technical problem to be solved by the present application is to provide a countersinking machine for front spring pressure plate which can automatically flip and continuously process multiple end faces of connecting holes with high efficiency.

[0004] To solve the above technical problems, the present application comprises a rack, and the structural characteristics are: one side of the rack is connected with a turntable capable of vertical sliding, forward and backward sliding and rotating through a turntable driving mechanism, an end face of the turntable away from the turntable driving mechanism is provided with a clamping mechanism capable of clamping the front spring pressure plate, a bracket supporting one end of the connecting hole of the front spring pressure plate is arranged on the rack, a sliding plate vertically sliding driven by a sliding plate driving mechanism is arranged on one side of the bracket, a drill bit driving motor is connected to one end of the sliding plate, and the drill bit driving motor is connected with a drill bit rotating connected to the other end of the sliding plate through a transmission mechanism.

[0005] Further, the turntable driving mechanism comprises a stand column installed on one side of the rack, a sliding seat vertically sliding driven by a first driving mechanism is connected to the stand column, a cross bar forward and backward sliding driven by a second driving mechanism is connected to the sliding seat, a large gear rotating driven by a third driving mechanism is connected to the cross bar, and the turntable is installed on one side of the large gear.

[0006] Further, the clamping mechanism comprises a clamping plate vertically installed on the turntable, two clamping rods respectively matched with the connecting grooves of the front spring pressure plate are arranged on one side of the clamping plate, a clamping block driving cylinder is installed on an end face of the clamping plate away from the clamping rods, and a clamping block matched with the groove on the front spring pressure plate is connected to the piston rod of the clamping block driving cylinder.

[0007] Further, the free end of each of the clamping rods extends obliquely away from the clamping plate.

[0008] Further, the bracket comprises two vertical plates arranged vertically side by side and a supporting plate arranged horizontally between the two vertical plates, and the supporting plate is spaced apart from the top end of the vertical plates.

[0009] Further, the inner side edge of the top end of each vertical plate is provided with a chamfer facilitating the sliding of the front spring plate, the output shaft of the pinion gear drive motor is provided with a sleeve, the gear shaft of the pinion gear is rotatably connected with the sleeve, and a torsion spring is arranged between the gear shaft and the sleeve.

[0010] Further, the lower part of the rack is provided with an inlet channel and an outlet channel arranged vertically side by side, the turntable is provided with a push plate driven by a push plate drive cylinder to slide forward and backward, and the turntable is provided with a sensor for detecting the position of the front spring plate.

[0011] Further, the inlet channel and the outlet channel each comprise a channel formed by the elongated clamping plate and clamping rod, the clamping plate of the inlet channel is provided with a conveyor belt driven by a conveyor belt drive motor, and the conveyor belt drive motor and the sensor are connected with a controller.

[0012] Further, the transmission mechanism comprises two transmission gears rotatably connected side by side on the sliding plate, one of the transmission gears is connected with the drill bit drive motor, and the other transmission gear is connected with the drill bit.

[0013] Further, the depth of the counterbore of the drill bit is equal to the height difference between the initial machining position of the sliding plate and the position when the sliding plate abuts against the bracket.

[0014] With the above structure, the turntable drive mechanism drives the turntable to slide vertically, forward and backward, and rotate, and cooperates with the drill bit on the slide to continuously countersink the multiple end faces of the connecting hole. This process eliminates the need for manual manipulation of the front spring pressure plate during machining, resulting in high machining efficiency. By providing a slide and a transmission mechanism, the drill bit can be inserted into the inner side to countersink the inner end face of the connecting hole, eliminating the need for drill bit installation and removal, reducing time and improving countersinking efficiency. A bracket supports one end of the connecting hole of the front spring pressure plate, securing the front spring pressure plate during countersinking to prevent it from swinging. By providing a chamfer on the inner side of the top of the vertical plate to facilitate the sliding of the front spring pressure plate, and by installing a sleeve on the output shaft of the pinion drive motor and connecting the sleeve to a torsion spring, the turntable can avoid tilting errors when it rotates 180 degrees. By providing the torsion spring and chamfer, the front spring pressure plate can be aligned by floating when the turntable's tilt angle does not reach 180 degrees. This avoids the need for high-precision large and small gears, reducing equipment costs. By setting up a feed channel, a conveyor belt, a discharge channel, a push plate, and a sensor, the front spring pressure plate slides into the clamping mechanism along the feed channel. The sensor ensures that the front spring pressure plate enters the set position. The turntable and the drill bit cooperate to complete the countersinking process. The material is then automatically discharged under the action of the discharge channel. Manual operation only requires pushing the front spring pressure plate into the feed channel. The entire countersinking process is completed automatically, which is highly efficient and reduces operational safety hazards. By setting the countersinking depth of the drill bit to the height difference between the initial processing position of the slide and the position when it abuts the bracket, that is, when the slide slides to abut the bracket on the bracket during processing, the processing is completed. This simplifies the program control of the vertical sliding of the slide, simplifies the operating steps, and reduces the manufacturing cost of the countersinking machine.

[0028] The stand 21 is mounted on one side of the frame 1, the sliding seat 22 vertically slidable on the stand 21, the crossbar 23 forward and backward slidable on the sliding seat 22 and the large gear 24 rotatably connected on the crossbar 23, refer to Figure 1 、 Figure 2 and Figure 6 , the sliding seat 22 is slidably connected with the crossbar 23 driven forward and backward by a second driving mechanism, specifically, the second driving mechanism includes a horizontal walking motor 223 mounted on the sliding seat 22, a horizontal walking gear 224 engaged with a row of tooth grooves arranged on the crossbar 23 is connected on the output shaft of the horizontal walking motor 223, wherein the right side of the sliding seat 22 is provided with an opening, the horizontal walking gear 224 passes through the opening to engage with the tooth grooves to realize the forward and backward sliding of the crossbar 23, that is, to drive the forward and backward sliding of the rotating disc 3, of course, the second driving mechanism can also be realized by a ball screw, a chain or an air cylinder. The crossbar 23 is rotatably connected with the large gear 24 driven by a third driving mechanism, specifically, the third driving mechanism includes a pinion driving motor 231 mounted on the end of the crossbar 23, a pinion 232 engaged with the large gear 24 is connected on the output shaft of the pinion driving motor 231, in use, the pinion driving motor 231 is used to drive the pinion 232 to rotate to drive the rotation of the large gear 24, the rotating disc 3 is mounted on one side (front side) of the large gear 24 through a connecting piece, the rotating large gear 24 will drive the rotating disc 3 to rotate, that is, to realize the rotation of the front spring pressing plate 9, to realize the taping work of the end face of the plurality of connecting holes 91 of the front spring pressing plate 9 (i.e. the front spring pressing plate 9 on both ends of the connecting hole 91), preferably, the large gear 24 is rotatably connected with the crossbar 23 through a cylinder shaft, and a through hole coaxial with the axis is arranged on the large gear 24, so that the line can pass through conveniently, avoiding the interference with the line when the rotating disc 3 rotates.

[0029] Refer toFigure 3 and Figure 7 The end face of the rotating disc 3 away from the rotating disc driving mechanism 2 is provided with a clamping mechanism 4 capable of clamping the front spring pressing plate 9, that is, the front end face of the rotating disc 3 is provided with the clamping mechanism 4, the front spring pressing plate 9 is irregular in shape, and the clamping mechanism 4 is arranged according to the characteristics of the connecting groove 92 and the recess 93 of the front spring pressing plate 9. Specifically, the clamping mechanism 4 comprises a clamping plate 41 vertically installed on the rotating disc 3, two clamping rods 42 respectively matched with the connecting groove 92 of the front spring pressing plate 9 and located on one side of the clamping plate 41. When the front spring pressing plate 9 is clamped, the axis of the rotating disc 3 is located on the middle section of the front spring pressing plate 9 (the center line of the connecting hole 91 is also located on the middle section), that is, when the rotating disc 3 rotates by 180 degrees or an integer multiple of 180 degrees, the plane composed of the center line of the connecting hole 91 of the front spring pressing plate 9 coincides with the axis of the rotating disc 3, and the connecting hole 91 on the front spring pressing plate 9 is symmetrical about the axis of the rotating disc 3 before and after rotation. In this way, after the rotating disc 3 rotates by 180 degrees, it only needs to adjust the front and rear positions and the vertical position to perform the counterbore machining, thereby avoiding the adjustment of the left and right positions. Preferably, in order to facilitate the placement of the front spring pressing plate 9, the free end of each clamping rod 42 is inclined to extend away from the clamping plate 41, that is, the opening of the end part is increased, thereby facilitating the insertion of the front spring pressing plate 9 into the clamping mechanism 4 along the front side of the clamping rod 42.

[0030] The end face of the clamping plate 41 away from the clamping rod 42 is provided with a clamping block driving cylinder 43, the piston rod of the clamping block driving cylinder 43 is connected with a clamping block 44 matched with the recess 93 on the front spring pressing plate 9. In the initial state, the clamping block 44 is located in the clamping block placing groove provided on the clamping plate 41, thereby avoiding interference with the clamping block 44 when the front spring pressing plate 9 is inserted from the front side. When the front spring pressing plate 9 is clamped, the front spring pressing plate 9 is clamped between the clamping plate 41 and the clamping rod 42, and the clamping block driving cylinder 43 drives the end of the clamping block 44 to abut against the recess, thereby avoiding the front spring pressing plate 9 from moving forward and backward relative to the rotating disc 3. Under the action of the clamping block 44, the front spring pressing plate 9 is firmly fixed on the clamping mechanism 4 on the front side of the rotating disc 3, thereby facilitating the subsequent rotating disc 3 to carry the front spring pressing plate 9 to rotate by 180 degrees for counterbore machining.

[0031] Referring to Figure 4 and Figure 5 The rack 1 is provided with a bracket 5 supporting one end of the connecting hole of the front spring pressing plate 9. Specifically, the bracket 5 comprises two vertical plates 51 arranged vertically and side by side and a supporting plate 52 horizontally arranged between the two vertical plates 51, and the supporting plate 52 is spaced apart from the top end of the vertical plate 51. The bottom end of the vertical plate 51 can be directly fixed on the rack 1. Preferably, a fixed plate is detachably installed on the rack 1, the bottom ends of the two vertical plates 51 are fixed on the fixed plate respectively, the position of the fixed plate can be adjusted, and after adjustment, the fixed plate and the rack 1 are fixedly connected by bolts. In this way, the position of the bracket 5 can be adjusted before counterboring, thereby reducing the installation error. Figure 3 and Figure 10As shown, when the counterboring is performed, the other end of the end face of the connecting hole 91 of the front spring pressing plate 9 to be machined is abutted on the supporting plate 52 (i.e. when the outer end of a connecting hole 91 is machined, the inner end face of the connecting hole 91 needs to be abutted on the supporting plate 52), at this time, the two vertical plates 51 on the upper side of the supporting plate 52 can further limit the left and right swinging of the front spring pressing plate 9 when counterboring, therefore, the top end of the supporting plate 52 and the vertical plate 51 are spaced, and the distance is generally 1-5 cm. Preferably, in order to facilitate the abutment of the end face of the connecting hole 91 of the front spring pressing plate 9 on the supporting plate 52, the top end of each vertical plate 51 is provided with a chamfer 511 on the inner side of the edge, which facilitates the sliding of the front spring pressing plate 9. The chamfer shown in the figure is a straight chamfer, and it can also be a round chamfer. By providing the chamfer 511, the spacing at the upper end can be increased, and the front spring pressing plate 9 is easily inserted between the two vertical plates 51. When the pinion 232 drives the gear 24 to rotate 180 degrees, errors are easily generated. When the machining precision of the gear 24 and the pinion 232 is improved in order to reduce errors, the cost is easily increased.

[0032] Preferably, the output shaft of the pinion driving motor 231 is provided with a sleeve, wherein the sleeve is fixedly connected with the output shaft of the pinion driving motor 231, and the gear shaft of the pinion 232 is rotatably connected with the sleeve, i.e. the gear shaft of the pinion 232 is inserted into the sleeve to achieve rotational connection. Alternatively, a bearing can be provided on the gear shaft of the pinion 232, the inner ring of the bearing is fixedly connected with the gear shaft of the pinion 232, the outer ring of the bearing is fixedly connected with the sleeve, and a torsional spring is arranged between the gear shaft of the pinion 232 and the sleeve, i.e. the torsional spring is sleeved on the gear shaft, one end of the torsional spring is connected with the gear shaft, and the other end is connected with the sleeve. In use, the end of the gear shaft can be protruded by a connecting column with a smaller diameter than the gear shaft, and the torsional spring is sleeved on the connecting column. The torsional force of the torsional spring is relatively large, and the torsional spring hardly deforms when the pinion 232 drives the gear 24 to rotate. When the rotating disc 3 vertically moves to insert the end of the front spring pressing plate 9 between the two vertical plates 51, if the rotating disc 3 is not rotated by 180 degrees but by 179 degrees, under normal circumstances, the end of the front spring pressing plate 9 cannot be inserted between the two vertical plates 51 on the upper side of the supporting plate 52, but the rotating disc 3 can float under the action of the torsional spring, so that the end of the front spring pressing plate 9 can be smoothly inserted between the two vertical plates 51 above the supporting plate 52. Of course, a chamfer 511 can also be provided on the front side of the top end of the vertical plate 51, and the front spring pressing plate 9 is inserted between the two vertical plates 51 from the front side in use.

[0033] Referring to Figure 4 and Figure 5, one end of the slide plate 6 is connected with a drill bit driving motor 61, the drill bit driving mechanism is power connected with a drill bit 63 which is rotationally connected with the other end of the slide plate 6 through a transmission mechanism 62, specifically, the slide plate 6 is arranged in a U shape, that is, it comprises an upper side plate, a lower side plate and a front side plate fixedly connected to the front ends of the upper side plate and the lower side plate, wherein the transmission mechanism 62 comprises two transmission gears rotationally connected on the slide plate 6 and meshing with each other, that is, the two transmission gears are rotationally connected between the upper side plate and the lower side plate, one of the transmission gears is power connected with the drill bit driving motor 61, and the other transmission gear is connected with the drill bit 63, so that the drill bit driving motor 61 rotates to drive the drill bit 63 to rotate to achieve the purpose of counterboring, which not only counterbores the outer end surface of the connecting hole 91, but also extends into and counterbores the inner end surface (that is, the inner end surface of the axial two end surfaces) of the connecting hole 91, that is Figure 10 The connecting hole 91 in the middle two figures is counterbored. It avoids the installation and removal of the drill bit, saves time and improves the counterboring efficiency. The slide plate driving mechanism 64 in the figure is fixed with a rack 641 at the front end of the slide plate 6, and a gear driving motor 642 is installed on the bracket 5, a gear 643 meshing with the rack 641 is installed on the output shaft of the gear driving motor 642, and in order to ensure the vertical sliding of the slide plate 6, two vertical sliding rods are fixed on the slide plate 6, and if the slide plate 6 does not swing after installation, one or two mounting seats for the vertical sliding rods can be provided on the bracket 5, of course, other ways can also be used to realize the vertical sliding of the slide plate 6, for example, the slide plate 6 can be driven to vertically slide by a ball screw or an air cylinder, and a bench drill or a drill press can also be installed on the machine frame 1, wherein the output shaft of the bench drill or the drill press connected with the drill bit is power connected with the transmission mechanism 62, so that the rotation of the drill bit 63 can be realized, and the up and down movement can also be realized.

[0034] Preferably, in order to simplify the program control of the vertical sliding of the slide plate 6, simplify the operation steps and reduce the manufacturing cost of the counterboring machine, the counterboring depth of the drill bit 63 is equal to the height difference between the initial processing position of the slide plate 6 and the position when it abuts against the bracket 5, that is, no matter where the slide plate 6 is initially located, as long as it vertically slides to abut against the bracket 5 (specifically, the bracket 5 in the bracket 5), it indicates that the processing is completed, the lower end surface of the slide plate 6 can directly abut against the bracket 5, or a fixed block can be provided on the bracket 5, when the slide plate 6 abuts against the fixed block, it also indicates that the processing is completed, so that the vertical sliding of the slide plate 6 can be automatically controlled, and manual driving can also be used, especially when the slide plate 6 is driven to descend by the bench drill, the operator does not need to observe whether the slide plate 6 slides to the set position, as long as it abuts (does not move), it indicates that the counterboring processing is completed, which is simple to operate.

[0035] In order to improve the processing efficiency, preferably, the feeding channel 7 and the discharging channel 8 are arranged below the rack 1 in parallel, specifically, the feeding channel 7 and the discharging channel 8 each include a channel formed by the elongated clamping plate 41 and the clamping rod 42, wherein the clamping plate 41 and the clamping rod 42 are fixed below the operating table of the rack 1 through the rod, and of course, other channels can also be arranged, as long as the direction of the front spring pressing plate 9 during sliding can be ensured to be consistent, in use, the front spring pressing plate 9 is pushed into the feeding channel 7, and initially, a plurality of front spring pressing plates 9 can be pushed in at a time, when the rotating disc 3 slides to the lower side corresponding to the feeding channel 7, one front spring pressing plate 9 is manually pushed to make the front spring pressing plate 9 close to the rotating disc 3 slide onto the clamping mechanism 4, preferably, the clamping plate 41 of the feeding channel 7 is provided with a conveying belt 71 driven by a conveying belt driving motor, the side wall of the front spring pressing plate 9 located on the feeding channel 7 is in contact with the conveying belt 71, and the front spring pressing plate 9 is conveyed to the clamping mechanism 4 through the conveying belt 71, in order to increase the friction, the surface of the conveying belt 71 can be provided with protrusions or rubber strips, the rotating disc 3 is provided with a sensor 32 for detecting the position of the front spring pressing plate 9, when the rear end of the front spring pressing plate 9 abuts against the rotating disc 3, the sensor 32 detects the signal, the sensor can be a distance sensor, a proximity switch or a travel switch, as long as the front spring pressing plate 9 contacting the rotating disc 3 can be detected, the conveying belt driving motor and the sensor 32 are both controlled by the controller, when the rotating disc 3 slides to the lower side corresponding to the feeding channel 7, the conveying belt driving motor drives the conveying belt to convey the front spring pressing plate 9, until the rear end of the last side of the front spring pressing plate 9 contacts the rotating disc 3, the sensor 32 sends a signal to the controller, and the controller controls the conveying belt driving motor to stop, so that the front spring pressing plate 9 is directly pushed into the feeding channel 7, and the feeding can be quickly and accurately completed, and manual observation is saved.
