Description

Technical Field

[0001] This invention relates to the field of bearing processing technology, and in particular to a grease injection cap device for bearing processing. Background Technology

[0002] In bearing manufacturing, grease injection and capping are key processes to ensure bearing performance and service life. Traditional bearing grease injection and capping operations are mostly completed manually or with semi-automated equipment, which presents several problems:

[0003] When operated manually, workers need to position the bearings, add grease, place the end caps, and press them together. This is not only labor-intensive and inefficient, but also makes it difficult to ensure the uniformity of grease application and the consistency of the pressing force. This can easily lead to quality problems such as poor bearing lubrication, loose end caps, or damage from overpressure. Semi-automatic equipment lacks effective monitoring and alarm mechanisms during operation. When key components such as motors and push rods used for bearing delivery and pressing malfunction, timely detection is not possible, and the equipment will continue to operate according to the preset program. This results in the continuous production of defective products and increases production costs. Summary of the Invention

[0004] This invention relates to a grease injection capping device for bearing processing, which solves the problem that existing semi-automatic equipment used for bearing capping lacks an effective monitoring and alarm mechanism for the equipment's operating status.

[0005] This invention provides a grease injection capping device for bearing processing, specifically comprising: a machine body; a transmission groove with a circular groove structure is formed on the left side of the top surface of the machine body, and a transmission plate with a circular block structure is disposed inside the transmission groove; the transmission plate is coaxially arranged with the transmission groove, and the diameter of the transmission groove is larger than the diameter of the transmission plate; a drive mounting groove is formed on the bottom surface of the machine body relative to the transmission groove, and a set of motors is fixedly installed inside the drive mounting groove, with the shaft end of the motors passing through the transmission groove and fixedly connected to the central part of the transmission plate; a limiting guide groove is formed on the top surface of the machine body, with one end of the limiting guide groove passing through the transmission groove and the other end passing through the right end surface of the machine body; the width of the limiting guide groove is one centimeter larger than the diameter of the bearing; a conveying mounting groove is formed on the bottom surface of the inner end of the limiting guide groove, with one end of the conveying mounting groove passing through the transmission groove and the other end passing through the right end surface of the machine body; a set of belt conveyors is installed inside the conveying mounting groove, and the belt conveyors convey to the left.

[0006] Furthermore, the outer circumferential surface of the transmission plate is provided with twelve transmission slots in an arc-shaped array; the circular outline formed by the transmission slots is tangent to the inner circumferential surface of the transmission slot.

[0007] Furthermore, a discharge slot is provided between the rear side of the bottom surface of the inner end of the transmission groove and the rear end face of the machine body. The bottom surface of the inner end of the discharge slot is an inclined surface structure that slopes downwards and backwards. When the motor is not running, one transmission slot corresponds to the position of the limiting guide slot, and another transmission slot corresponds to the position of the discharge slot. The top opening of the discharge slot is directly below the transmission slot.

[0008] Furthermore, a supporting block is fixedly installed on the upper left side of the machine body via two support plates. A set of electric push rods is fixedly installed on the top surface of the supporting block. The push rod end of the electric push rod passes through the bottom surface of the supporting block and is fixedly installed with a pressure plate for bearing cover operation. When the motor is not running, a transmission slot is coaxial with the pressure plate.

[0009] Furthermore, a control box is fixedly installed on the support plate located on the front side. The control box is electrically connected to the belt conveyor, motor, and electric push rod. A set of pressure sensors is embedded in the left side of the inner circumference of the transmission groove. The pressure sensors are electrically connected to the control box.

[0010] Furthermore, a lower sensing groove is provided on the left side of the bottom surface of the inner end of the transmission groove. A set of rotary proximity switches is fixedly installed inside the lower sensing groove. The rotary proximity switches are electrically connected to the control box, and the sensing end of the rotary proximity switches faces upward. The bottom surface of the transmission plate is arranged in a circular array with twelve lower mating sensing blocks embedded in it, which can cooperate with the rotary proximity switches. The twelve lower mating sensing blocks are adjacent to twelve transmission slots. When a transmission slot and the pressure plate are coaxial, the lower mating sensing block adjacent to that transmission slot corresponds to the position of the lower sensing groove. At this time, the lower mating sensing block is within the sensing range of the rotary proximity switch. When the lower mating sensing block is misaligned with the lower sensing groove, the lower mating sensing block is out of the sensing range of the rotary proximity switch.

[0011] Furthermore, a rotation status audible and visual alarm is fixedly installed on the top surface of the machine body, and the rotation status audible and visual alarm is electrically connected to the control box; the control box also has a rotation frequency determination timing module electrically connected to it; when the control box controls the motor shaft to rotate, the motor shaft drives the transmission plate to rotate one-twelfth of a revolution, and simultaneously controls the rotation frequency determination timing module to start timing; the timing value of the rotation frequency determination timing module is one second longer than the time it takes for the motor shaft to drive the transmission plate to rotate one-twelfth of a revolution; when the rotation induction proximity switch senses the lower mating induction block, the rotation induction proximity switch sends a feedback signal to the control box, and the control box controls the rotation frequency determination timing module to stop timing; when the timing value of the rotation frequency determination timing module is reached, the rotation frequency determination timing module sends a feedback signal to the control box, and the control box controls the rotation status audible and visual alarm to start.

[0012] Furthermore, an upper sensing groove is formed on the bottom surface of the supporting block relative to the pressure plate. A set of telescopic proximity switches is fixedly installed inside the upper sensing groove, with the sensing end of the telescopic proximity switches facing downwards. The telescopic proximity switches are electrically connected to the control box. An upper mating sensing block is embedded in the top surface of the pressure plate relative to the upper sensing groove, which can cooperate with the telescopic proximity switches. When the push rod end of the electric push rod is in the fully retracted state, the upper mating sensing block is within the sensing range of the telescopic proximity switches. When the push rod end of the electric push rod extends, the upper mating sensing block leaves the sensing range of the telescopic proximity switches.

[0013] Furthermore, a telescopic status audible and visual alarm electrically connected to the control box is fixedly installed on the top surface of the supporting top block; a telescopic frequency determination and timing module electrically connected to it is provided inside the supporting top block; when the pressure sensor senses pressure, the pressure sensor feeds a feedback signal to the control box, the control box controls the push rod end of the electric push rod to extend or retract once, and simultaneously controls the telescopic frequency determination and timing module to start timing; the timing value of the telescopic frequency determination and timing module is one second longer than the time for the push rod end of the electric push rod to extend or retract once; when the telescopic proximity switch interferes with the upper mating sensing block, the telescopic proximity switch feeds a feedback signal to the control box, the control box controls the telescopic frequency determination and timing module to stop timing; when the timing value of the telescopic frequency determination and timing module is reached, the telescopic frequency determination and timing module feeds a feedback signal to the control box, the control box controls the telescopic status audible and visual alarm to start.

[0014] This invention provides a grease injection cap device for bearing processing, which has the following beneficial effects:

[0015] The limiting guide groove of this invention is one centimeter wider than the bearing diameter, which provides good guidance and limiting for the bearing. Combined with a belt conveyor, it ensures stable bearing transport, effectively avoiding offset and jamming during transport. This ensures the bearing accurately enters the transmission slots of the transmission plate. The outer circumference of the transmission plate has twelve transmission slots arranged in a ring array. Driven by a motor, the bearing can be continuously fed and moved. The pressure plate, driven by an electric push rod, completes the capping operation. The entire process is automated through a control box, reducing manual intervention, significantly improving production efficiency, and meeting the needs of continuous production. When the bearing moves to the pressure sensor position, the pressure sensor feeds a signal back to the control box, triggering the electric push rod to drive the pressure plate for capping. The program set in the control box ensures consistent pressure and stroke for each capping operation, effectively avoiding quality problems such as loose end caps and overpressure damage caused by uneven capping force in manual operation or traditional equipment, thus improving the quality stability of the bearing products.

[0016] This invention's equipment, through the configuration of a rotation-inductive proximity switch, a lower-side sensing block, and a rotation frequency determination and timing module, can promptly activate an audible and visual alarm when the motor-driven transmission plate malfunctions and the rotation time exceeds a set value. This allows staff to stop the machine for repairs in a timely manner, preventing the fault from escalating and causing product damage. Furthermore, the equipment, through the configuration of a telescopic-inductive proximity switch, an upper-side sensing block, and a telescopic frequency determination and timing module, can monitor the telescopic state of the electric push rod. When the telescopic state of the electric push rod malfunctions, an audible and visual alarm is activated, ensuring the normal operation of the capping process. Attached Figure Description

[0034] Example 1: Please refer to Figures 1 to 9 :

[0035] This invention proposes a grease injection capping device for bearing processing, comprising: a body 1, a transmission groove 101 with a circular groove structure opened on the left side of the top surface of the body 1, and a transmission plate 3 with a circular block structure disposed inside the transmission groove 101; the transmission plate 3 is coaxially arranged with the transmission groove 101, and the diameter of the transmission groove 101 is larger than the diameter of the transmission plate 3; a drive mounting groove 1012 is opened on the bottom surface of the body 1 relative to the transmission groove 101, and a set of motors 108 is fixedly installed inside the drive mounting groove 1012, the shaft end of the motors 108 passing through the transmission groove 101 and fixedly connected to the axial part of the transmission plate 3; the body 1 A limiting guide groove 103 is provided on the top surface, one end of which passes through the transmission groove 101, and the other end passes through the right end face of the machine body 1; the width of the limiting guide groove 103 is one centimeter larger than the diameter of the bearing; a conveying installation groove 107 is provided on the bottom surface of the inner end of the limiting guide groove 103, one end of which passes through the transmission groove 101, and the other end passes through the right end face of the machine body 1; a set of belt conveyors 104 is installed inside the conveying installation groove 107, and the belt conveyors 104 convey to the left; the outer circumference of the transmission plate 3 has twelve transmission slots 301 with arc-shaped groove structures arranged in a ring array; the transmission slots 301 constitute... The circular outline of the transmission groove 101 is tangent to the inner circumferential surface of the transmission groove 101; a discharge slot 106 is formed between the rear side of the bottom surface of the inner end of the transmission groove 101 and the rear end face of the machine body 1, and the bottom surface of the inner end of the discharge slot 106 is an inclined surface structure that slopes downward to the rear; when the motor 108 is not running, one transmission slot 301 corresponds to the position of the limiting guide slot 103, and another transmission slot 301 corresponds to the position of the discharge slot 106, and the top opening end of the discharge slot 106 is directly below the transmission slot 301; a supporting top block 2 is fixedly installed on the upper left side of the machine body 1 by two support plates 201. A set of electric push rods 202 are fixedly installed on the top surface of the supporting block 2. The push rod end of the electric push rod 202 passes through the bottom surface of the supporting block 2 and is fixedly installed with a pressure plate 204 for bearing cover operation. When the motor 108 is not started, a transmission slot 301 is coaxial with the pressure plate 204. A control box 105 is fixedly installed on the support plate 201 located on the front side. The control box 105 is electrically connected to the belt conveyor 104, the motor 108 and the electric push rods 202. A set of pressure sensors 109 is embedded in the left side of the inner circumference of the transmission slot 101. The pressure sensors 109 are electrically connected to the control box 105.

[0036] The transmission groove 101 has a lower sensing groove 1010 on the left side of the bottom surface of its inner end. A set of rotational proximity switches 1011 are fixedly installed inside the lower sensing groove 1010. The rotational proximity switches 1011 are electrically connected to the control box 105, and the sensing end of the rotational proximity switches 1011 faces upward. The bottom surface of the transmission plate 3 has twelve lower mating sensing blocks 302 embedded in a circular array, which can sense and cooperate with the rotational proximity switches 1011. The twelve lower mating sensing blocks 302 are respectively The twelve transmission slots 301 are adjacent to each other. When a transmission slot 301 and the pressure plate 204 are coaxial, the lower mating sensing block 302 of the adjacent transmission slot 301 corresponds to the lower sensing groove 1010. At this time, the lower mating sensing block 302 is within the sensing range of the rotation sensing proximity switch 1011. When the lower mating sensing block 302 and the lower sensing groove 1010 are misaligned, the lower mating sensing block 302 is removed from the sensing range of the rotation sensing proximity switch 1011. A rotation status audible and visual alarm 102 is fixedly installed on the top surface and is electrically connected to the control box 105. The control box 105 also contains a rotation frequency determination and timing module 1013, which is electrically connected to it. When the control box 105 controls the shaft end of the motor 108 to rotate, the shaft end of the motor 108 drives the transmission plate 3 to rotate one-twelfth of a revolution, and simultaneously controls the rotation frequency determination and timing module 1013 to start timing. The timing value of the rotation frequency determination and timing module 1013 is more than the rotation value of the motor 108. The shaft end drives the transmission plate 3 to rotate one-twelfth of a revolution in one second; when the rotation sensing proximity switch 1011 senses the lower mating sensing block 302, the rotation sensing proximity switch 1011 sends a feedback signal to the control box 105, and the control box 105 controls the rotation frequency determination timing module 1013 to turn off the timing; when the timing value of the rotation frequency determination timing module 1013 is reached, the rotation frequency determination timing module 1013 sends a feedback signal to the control box 105, and the control box 105 controls the rotation status audible and visual alarm 102 to start.

[0037] The supporting top block 2 has an upper sensing groove 206 on its bottom surface relative to the pressure plate 204. A set of telescopic proximity switches 207 is fixedly installed inside the upper sensing groove 206, with the sensing end of the telescopic proximity switches 207 facing downwards. The telescopic proximity switches 207 are electrically connected to the control box 105. An upper mating sensing block 205, which can cooperate with the telescopic proximity switches 207, is embedded in the top surface of the pressure plate 204 relative to the upper sensing groove 206. When the push rod end of the electric push rod 202 is fully retracted, the upper mating sensing block 205 is within the sensing range of the telescopic proximity switches 207. When the push rod end of the electric push rod 202 extends, the upper mating sensing block 205 leaves the sensing range of the telescopic proximity switches 207. A telescopic status audible and visual alarm 203, electrically connected to the control box 105, is fixedly installed on the top surface of the supporting top block 2. The support block 2 is internally equipped with a telescopic frequency determination and timing module 208 electrically connected to it. When the pressure sensor 109 senses pressure, the pressure sensor 109 sends a feedback signal to the control box 105. The control box 105 controls the push rod end of the electric push rod 202 to extend or retract once, and simultaneously controls the telescopic frequency determination and timing module 208 to start timing. The timing value of the telescopic frequency determination and timing module 208 is one second longer than the time it takes for the push rod end of the electric push rod 202 to extend or retract once. When the telescopic proximity switch 207 interferes with the upper mating sensing block 205, the telescopic proximity switch 207 sends a feedback signal to the control box 105, and the control box 105 controls the telescopic frequency determination and timing module 208 to stop timing. When the timing value of the telescopic frequency determination and timing module 208 is reached, the telescopic frequency determination and timing module 208 sends a feedback signal to the control box 105, and the control box 105 controls the telescopic status audible and visual alarm 203 to start.

[0038] The working principle of this embodiment:

[0039] The bearing to be capped is placed in the inlet of the limiting guide groove 103 on the right end face of the machine body 1. Since the width of the limiting guide groove 103 is one centimeter larger than the diameter of the bearing, it can guide and limit the bearing to prevent it from shifting during the conveying process. At the same time, the belt conveyor 104 in the conveying installation groove 107 starts to the left and drives the bearing to move along the limiting guide groove 103 towards the transmission groove 101 through friction.

[0040] When the bearing is delivered to the end of the limiting guide groove 103, it will enter the transmission slot 301 on the outer circumference of the transmission plate 3. Since there is a transmission slot 301 that is aligned with the outlet of the limiting guide groove 103 in the initial state, it can ensure that the bearing enters the transmission slot 301 accurately.

[0041] The control box 105 sets the interval time for each rotation of the motor 108. When the interval time is reached, the motor 108 shaft drives the transmission plate 3 to rotate clockwise by one-twelfth of a turn, thereby feeding the bearing into the transmission slot 301. When the bearing is fed to the left side of the inner circumferential surface of the transmission slot 101, the circular outline formed by the transmission slot 301 is tangent to the inner circumferential surface of the transmission slot 101. Therefore, the bearing that is limited and locked in the transmission slot 301 will contact the pressure sensor 109 on the left side of the inner circumferential surface of the transmission slot 101. The pressure sensor 109 will sense the pressure of the bearing and feed the signal back to the control box 105, triggering the subsequent capping process. Furthermore, when the control box 105 controls the shaft end of the motor 108 to rotate, it will simultaneously control the rotation frequency determination timing module 1013 to start timing.

[0042] Because the timing value of the rotation frequency determination timing module 1013 is one second longer than the time it takes for the transmission plate 3 to rotate one-twelfth of a revolution driven by the shaft end of the motor 108, if the motor 108 is in normal operation, the rotation induction proximity switch 1011 will sense the lower cooperating induction block 302 and send a feedback signal to the control box 105 to control the timing of the rotation frequency determination timing module 1013 to turn off, thus avoiding false alarms. However, if the motor 108 malfunctions and its rotation time exceeds the timing value of the rotation frequency determination timing module 1013, the rotation frequency determination timing module 1013 cannot be turned off. When the timing value of the rotation frequency determination timing module 1013 is reached, the rotation frequency determination timing module 1013 sends a feedback signal to the control box 105, and the control box 105 controls the rotation status audible and visual alarm 102 to start, so as to remind the surrounding staff that the motor 108 has malfunctioned and needs to be stopped and repaired in time, so as to avoid damage to the bearings caused by the operation due to the malfunction.

[0043] When pressure sensor 109 senses pressure, it sends a feedback signal to control box 105. Control box 105 controls the extension and retraction of the push rod end of electric push rod 202 once, and simultaneously controls the extension and retraction frequency determination timing module 208 to start timing. When the push rod end of electric push rod 202 extends, it will synchronously drive the pressure plate 204 to move downward, thereby performing a capping operation on the bearing corresponding to its position, and then automatically retracting to complete one capping operation. Furthermore, when electric push rod 202 is in normal operation, the extension and retraction time of the push rod end of electric push rod 202 will not exceed the timing value of extension and retraction frequency determination timing module 208. Therefore, after the push rod end of electric push rod 202 retracts normally, the upper cooperating sensing block 205 will be within the sensing range of extension and retraction proximity switch 207, and extension and retraction proximity switch 207 will sense... After the upper sensing block 205 is engaged, a feedback signal is sent to the control box 105. The control box 105 controls the extension frequency determination timing module 208 to shut down to avoid false alarms. However, if the electric push rod 202 malfunctions and the extension time of its push rod end exceeds the timing value of the extension frequency determination timing module 208, the extension frequency determination timing module 208 cannot be shut down. When the timing value of the extension frequency determination timing module 208 is reached, the extension frequency determination timing module 208 sends a feedback signal to the control box 105. The control box 105 then activates the extension status audible and visual alarm 203 to alert surrounding personnel that the electric push rod 202 has malfunctioned and needs to be stopped for maintenance in time to avoid damage to the bearings caused by the malfunction.

[0044] After the bearing capping process is completed, the bearing with the capped cap is transferred to the unloading slot 106 under the continuous feeding of the bearing by the motor 108 and the transmission plate 3. Since the top opening of the unloading slot 106 is directly below the transmission slot 301, the bearing will disengage from the transmission slot 301 and fall into the unloading slot 106. Since the bottom surface of the unloading slot 106 is a sloped structure that slopes downwards and backwards, the bearing will slide out along the sloped surface of the unloading slot 106 and complete the finished product collection operation.

[0045] The process of this equipment is automatically executed in a cycle through the program settings of the control box 105. The twelve transmission slots 301 on the transmission plate 3 can sequentially receive bearings to achieve continuous processing.
