Description

Technical Field

[0001] The present invention relates to the technical field of workpiece processing, and specifically relates to a positioning transfer and conveying structure for workpiece processing. Background Technique

[0002] A bearing is a mechanical element that restricts relative movement within the required range of motion and reduces friction between moving parts. The design of a bearing can provide free linear movement of moving parts or free rotation around a fixed axis, or prevent movement by controlling the vector of the normal force acting on the moving parts. During the processing of bearings, a conveyor can convey the inner and outer steel rings of the bearings.

[0003] However, when conveying the inner and outer steel rings of a bearing through a conveyor belt, the steel rings are generally directly placed on the conveyor belt through the previous process. Since the moving positions of the steel rings are not restricted, when moving towards the direction close to the conveying component, they are likely to be crowded together, which is not convenient for the conveying component to transfer them one by one; during the movement, it is also very difficult for the conveying component to ensure the equidistant conveying of the steel rings, which may affect the accuracy of the next process when grasping the steel rings; and the steel rings run off during the conveying process, and may also fall off the conveyor belt, thereby affecting the entire conveying efficiency of the bearing. Summary of the Invention

[0004] In view of the problems in the prior art, the present invention provides a positioning transfer and conveying structure for workpiece processing.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a positioning transfer and conveying structure for workpiece processing, including a conveying frame, on which a material blocking mechanism is fixedly installed; a material conveying mechanism is snap-fitted at a position of the conveying frame close to the material blocking mechanism; a transfer frame and a base are fixed to the bottom of the material conveying mechanism; a limiting mechanism is slidably installed on the transfer frame; and a driving mechanism is rotatably installed on the base.

[0006] The material conveying mechanism includes a stop block and a surrounding plate. The stop block and the surrounding plate are snap-fitted on the conveying frame, and both the stop block and the surrounding plate are fixedly connected to the transfer frame. The bottom end of the surrounding plate is fixedly connected to a bottom plate, on which a rotating shaft is rotatably connected. A chuck is fixedly installed on the rotating shaft. The chuck is annularly and equidistantly provided with a plurality of grooves. Rollers are rotatably installed at one end of the stop block and the surrounding plate close to the transfer frame. The chuck is rotatably connected to the stop block, the surrounding plate, and the bottom plate. The parts of the stop block and the surrounding plate in contact with the chuck are both arranged in an arc surface structure. The base is located at the bottom end of the bottom plate, and the rotating shaft is rotatably connected to the base and is located at the central part of the chuck.

[0007] Specifically, the driving mechanism includes a bracket and a motor, the bracket is fixedly connected to the base, the motor is fixedly installed on the bracket, the output end of the motor is fixedly connected to a rotating rod through a coupling, the rotating rod is fixedly connected to a first guide wheel, the rotating shaft is fixedly connected to a second guide wheel, belts are wrapped around the first guide wheel and the second guide wheel, the rotating rod is rotatably connected to the base, the first guide wheel and the second guide wheel are both arranged in an "I" shape, the inner diameter of the first guide wheel is larger than the inner diameter of the second guide wheel, and the diameter of the rotating rod is larger than the diameter of the rotating shaft.

[0008] Specifically, the limiting mechanism includes a sleeve rod and a handwheel. The sleeve rod is rotatably connected to the transfer frame, a handwheel is fixedly installed on the end of the sleeve rod, and a clamping rod is threadedly connected to the sleeve rod, a support rod is fixedly connected to the clamping rod, two sliding rods are fixedly connected to the support rod, and a clamping block is fixedly installed on the end of the sliding rod. The sleeve rod is located on the side of the transfer frame away from the conveying frame, and the two sliding rods are symmetrically arranged about the clamping rod.

[0009] Specifically, the material blocking mechanism includes a support rod and a support block. The support block is fixedly connected to the conveying frame, the top of the support block is fixedly connected to the support rod, a connecting shaft is fixedly installed on the support rod, and a material blocking rod is fixedly connected to the connecting shaft. The support block is located on a side of the conveying frame close to the stop block, the material blocking rod is inclined, and the end of the stop block and the enclosure close to the material blocking rod are both arranged in an inclined structure.

[0010] The beneficial effects of the present invention are:

[0011] (1) The present invention discloses a positioning transfer conveying structure for workpiece processing. The processed bearing is unloaded onto a conveying frame. The bearing can be moved to a position close to a material-blocking mechanism by a conveyor belt rotating on the conveying frame. Since there is a gap between the material-blocking mechanism and the material-transferring mechanism, the bearing passes through the gap under the driving action of the conveyor belt and moves to a position between the material-blocking mechanism and the material-transferring mechanism, thereby facilitating the subsequent conveying of the bearings one by one. That is, the processed bearing workpiece is unloaded onto the top of the conveying frame. Since a conveyor belt is rotatably installed on the conveying frame, starting the control switch of the conveying frame can cause the conveyor belt to transport the bearing to the position close to the material-blocking mechanism during the rotation process. Near the material blocking rod, the connecting shaft fixed on the material blocking rod is fixed inside the support rod, thereby making the material blocking rod in an inclined state; when the moving bearing contacts the inclined material blocking rod, it is blocked on the outside of the material blocking rod, and a gap is provided between the end of the material blocking rod away from the connecting shaft and the enclosure, and the bearing blocked on the side wall of the material blocking rod can pass through the gap and move to the position between the material blocking rod and the enclosure under the driving action of the conveyor belt, and a chuck is rotatably installed on the inner side of the enclosure, and the bearing can move to the groove provided in the chuck during the movement, so that when the chuck rotates subsequently, the bearings stored in the groove can be transported one by one.

[0012] (2) The positioning transfer and conveying structure for workpiece processing described in the present invention starts the control switch of the driving mechanism installed in the base, so that it drives some components of the material transfer mechanism to rotate. When the material transfer mechanism rotates, the bearings can be inserted into the interior thereof one by one, and then the bearings can be transferred to the transfer rack during the rotation process, that is: turn on the motor switch installed on the bracket, and the motor drives the rotating rod to rotate inside the base. Since a first guide wheel is fixed on the rotating rod, when the first guide wheel rotates with the rotating rod, the belt wrapped around its side wall can drive the second guide wheel to rotate. The second guide wheel is fixed to the side wall of the rotating shaft. When the rotating shaft rotates in the bottom plate and the base, the side wall of the rotating shaft can be fixed. A fixed chuck rotates on the top of the bottom plate, and the chuck drives the bearing engaged in the groove to rotate together, so that the bearing can move toward the direction close to the block. Since a gap is left between the block and the enclosure at one end away from the material blocking rod, a transfer rack is installed at the bottom of the gap, and a conveyor belt is rotatably installed in the transfer rack. When the bearing transported by the chuck rotates and moves to the conveyor belt of the transfer rack, it can be transported out of the block and the enclosure through the moving conveyor belt; and rollers are also rotatably installed at the parts of the block and the enclosure close to the transfer rack. The bearing contacts the roller when moving, which can drive the roller to rotate. The setting of the roller also facilitates reducing the contact area between the bearing and the block and the enclosure.

[0013] (3) The present invention discloses a positioning, transfer and conveying structure for workpiece processing, a rotating limiting mechanism, which adjusts the distance between the bearing and the inner wall of the transfer frame according to the diameter of the bearing. When the conveyor belt installed on the transfer frame rotates, the bearing can be conveyed to the next processing line, that is: before conveying the bearing through the transfer frame, the hand wheel is rotated to drive the sleeve rod to rotate inside the transfer frame. The sleeve rod is threaded with a clamping rod, and a push rod is fixed to the end of the clamping rod away from the hand wheel. When the sleeve rod rotates, the clamping rod can only slide along the inner wall of the transfer frame under the limiting action of the sliding rods fixed on both sides, thereby causing the push rod to slide in the direction close to the conveying frame. When the conveyor belt on the transfer frame drives the bearing to move, the push rod contacts the bearing, so that the bearing can always move in the same straight line, which is beneficial to prevent the bearing from running off and affecting the normal operation of the next processing line.

Detailed implementation manners

[0023] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0024] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 shown, a positioning transfer and conveying structure for workpiece processing according to the present invention includes a conveying rack 1, on which a material blocking mechanism 2 is fixedly installed; a material transferring mechanism 3 is snap-fitted and installed at a position of the conveying rack 1 close to the material blocking mechanism 2; a transfer rack 4 and a base 6 are fixed to the bottom of the material transferring mechanism 3; a limiting mechanism 5 is slidably installed on the transfer rack 4; a driving mechanism 7 is rotatably installed on the base 6;

[0025] Specifically, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the material transfer mechanism 3 includes a stop block 301 and a baffle 302. The stop block 301 and the baffle 302 are snap-fitted and installed on the conveying frame 1, and both the stop block 301 and the baffle 302 are fixedly connected to the transfer frame 4. The bottom end of the baffle 302 is fixedly connected to a bottom plate 306. A rotating shaft 304 is rotatably connected to the bottom plate 306, and the rotating shaft 304 is rotatably connected to the base 6. A chuck 303 is fixedly installed on the rotating shaft 304, and the chuck 303 is rotatably connected to the stop block 301, the baffle 302, and the bottom plate 306. The rotating shaft 304 drives the chuck 303 to rotate on the top of the bottom plate 306, which can make the bearing clamped inside the chuck 303 move towards the direction close to the stop block 301; the parts of the stop block 301 and the baffle 302 in contact with the chuck 303 are both arranged in an arc surface structure. The chuck 303 is provided with a number of grooves 305 at equal intervals in a ring shape. The grooves 305 limit the bearings, so that the bearings are separately clamped inside the chuck 303; a roller 307 is rotatably installed at one end of the stop block 301 and the baffle 302 close to the transfer frame 4. Since there is a gap at one end of the stop block 301 and the baffle 302 away from the baffle rod 201, when the bearing conveyed by the rotation of the chuck 303 moves onto the conveyor belt of the transfer frame 4, it can be conveyed out of the inside of the stop block 301 and the baffle 302 by the moving conveyor belt; when the bearing moves, it contacts the roller 307, which can drive the roller 307 to rotate. Moreover, the setting of the roller 307 also facilitates reducing the contact area between the bearing and the stop block 301 and the baffle 302.

[0026] Specifically, as Figure 5 , Figure 6 and Figure 7 shown, the driving mechanism 7 includes a bracket 701 and a motor 702. The bracket 701 is fixedly connected to the base 6, and the motor 702 is fixedly installed on the bracket 701. The output end of the motor 702 is fixedly connected to a rotating rod 703 through a coupling. A first guide wheel 704 is fixedly connected to the rotating rod 703. The motor 702 drives the rotating rod 703 to rotate inside the base 6, so that the rotating rod 703 drives the first guide wheel 704 to rotate; a second guide wheel 706 is fixedly connected to the rotating shaft 304. A belt 705 is wound around both the first guide wheel 704 and the second guide wheel 706. The first guide wheel 704 drives the belt 705 wound around its side wall to rotate, so as to drive the second guide wheel 706 to rotate. Furthermore, the second guide wheel 706 drives the rotating shaft 304 to rotate in the bottom plate 306 and the base 6; the rotating rod 703 is rotatably connected to the base 6. Both the first guide wheel 704 and the second guide wheel 706 are arranged in an "I" shape structure, which can prevent the belt 705 from falling off from the first guide wheel 704 and the second guide wheel 706.

[0027] Specifically, as Figure 1 , Figure 3 , Figure 4and Figure 5 As shown, the limiting mechanism 5 includes a sleeve rod 503 and a hand wheel 504, the transfer frame 4 is rotatably connected with the sleeve rod 503, the sleeve rod 503 is located on the side of the transfer frame 4 away from the conveying frame 1, and the end of the sleeve rod 503 is fixedly installed with a hand wheel 504, and the hand wheel 504 is rotated to drive the sleeve rod 503 to rotate inside the transfer frame 4, and the sleeve rod 503 is threadedly connected with a clamping rod 502, and the clamping rod 502 is fixedly connected with a push rod 501, and the push rod 501 is fixedly connected with two sliding rods 506. When the sleeve rod 503 rotates, the clamping rod 502 slides along the inner wall of the transfer frame 4 under the limitation of the sliding rod 506; the end of the sliding rod 506 is fixedly installed with a clamping block 505, and the two sliding rods 506 are symmetrically arranged about the clamping rod 502, and the clamping block 505 limits the sliding rod 506 to prevent the end of the sliding rod 506 from sliding out of the transfer frame 4.

[0028] Specifically, Figure 1 and Figure 2 As shown, the blocking mechanism 2 includes a support rod 203 and a support block 204. The conveying frame 1 is fixedly connected with the support block 204. The top of the support block 204 is fixedly connected with the support rod 203. The support rod 203 is fixedly installed with a connecting shaft 202. The connecting shaft 202 is fixedly connected with a blocking rod 201. The processed bearing workpiece is unloaded to the top of the conveying frame 1. Starting the conveying frame 1 can make the conveyor belt convey the bearing to a position close to the blocking rod 201 during the rotation process; the support block 204 is located at On the side of the conveying frame 1 close to the stop block 301, the stop rod 201 is set at an angle; when the moving bearing contacts the stop rod 201, it will be blocked on the outside of the stop rod 201; the stop block 301 and the end of the enclosure 302 close to the stop rod 201 are both set in an inclined structure, and a gap is provided between the end of the stop rod 201 away from the connecting shaft 202 and the enclosure 302. Under the driving action of the conveyor belt, the bearing blocked on the side wall of the stop rod 201 can pass through the gap and move to the position between the stop rod 201 and the enclosure 302.

[0029] When the present invention is in use, first, the processed bearing workpiece is unloaded to the top of the conveyor frame 1. Since a conveyor belt is rotatably installed on the conveyor frame 1, the control switch of the conveyor frame 1 is started, so that the conveyor belt can convey the bearing to a position close to the blocking rod 201 during the rotation process. Since the connecting shaft 202 fixed on the blocking rod 201 is fixed inside the support rod 203, the blocking rod 201 is in an inclined state; when the moving bearing contacts the inclined blocking rod 201, it is blocked on the outside of the blocking rod 201. , and a gap is provided between the end of the blocking rod 201 away from the connecting shaft 202 and the enclosure 302. The bearing blocked by the side wall of the blocking rod 201 can pass through the gap and move to the position between the blocking rod 201 and the enclosure 302 under the driving action of the conveyor belt, and a chuck 303 is rotatably installed on the inner side of the enclosure 302. The bearing can move to the groove 305 provided in the chuck 303 during the movement. In this way, when the chuck 303 rotates later, the bearings stored in the groove 305 can be transported one by one;

[0030] Turn on the switch of the motor 702 installed on the bracket 701, and the motor 702 drives the rotating rod 703 to rotate inside the base 6. Since the first guide wheel 704 is fixed on the rotating rod 703, when the first guide wheel 704 rotates with the rotating rod 703, the belt 705 wrapped around its side wall can drive the second guide wheel 706 to rotate. The second guide wheel 706 is fixed to the side wall of the rotating shaft 304. When the rotating shaft 304 rotates in the bottom plate 306 and the base 6, the chuck 303 fixed on its side wall can rotate on the top of the bottom plate 306. The chuck 303 drives the bearing engaged in the groove 305 to rotate together, so that the bearing can move toward the direction close to the stopper 301. The stopper 301 and the enclosure 302 are moved in a rotational manner, and a roller 307 is also rotatably installed at the part of the stopper 301 and the enclosure 302 close to the transfer frame 4. The bearing contacts with the roller 307 when the bearing moves to the stopper 301 and the enclosure 302, and the roller 307 can be driven to rotate. The setting of the roller 307 is also convenient for reducing the contact area between the bearing and the stopper 301 and the enclosure 302.

[0031] Before the bearing is conveyed by the transfer rack 4, rotate the handwheel 504 to drive the sleeve rod 503 to rotate inside the transfer rack 4. A clamping rod 502 is threadedly connected to the sleeve rod 503, and an abutting rod 501 is fixed to the end of the clamping rod 502 away from the handwheel 504. When the sleeve rod 503 rotates, the clamping rod 502 can only slide along the inner wall of the transfer rack 4 under the limiting action of the sliding rods 506 fixed on both sides, so that the abutting rod 501 slides towards the conveying rack 1. When the bearing is moved by the conveyor belt on the transfer rack 4, the abutting rod 501 contacts the bearing, which can make the bearing move in a straight line all the time, thus facilitating the prevention of the bearing from running off track and affecting the normal operation of the next processing line.
