Description

Technical Field

[0001] The invention belongs to the field of metal workpiece processing equipment, and in particular relates to an automatic material collecting and rubbing machine for producing transmission parts. Background Art

[0002] Rubbing refers to processing specific textures or patterns on the metal surface to increase the friction coefficient of the transmission component surface, improve the grip between components, avoid slipping, and improve transmission efficiency. In this process, the rubbing machine plays a vital role. According to the different transmission methods, the rubbing machine is mainly divided into two categories: one is the electrical system transmission based on sensors and actuators, and the other is the mechanical system transmission relying on pure mechanical structure.

[0003] The electrical system driven rubbing machine has become the mainstream choice of the current fully automatic rubbing machine due to its advantage of easy automation. However, it has also exposed some problems in practical application:

[0004] First, the sensors in the electrical system are very sensitive to the temperature, humidity and other conditions of the working environment. External interference can easily cause sensor reading distortion and affect the accuracy of the rubbing. Therefore, the rubbing machine driven by the electrical system has more stringent requirements on the processing environment and needs to operate in a relatively stable environment to ensure the accuracy of the sensor and the quality of the rubbing.

[0005] Secondly, compared with mechanical system transmission, the design of electrical system transmission is more complicated, involving the precise coordination of multiple links such as sensors, actuators and control systems. This means that in terms of installation, commissioning, daily maintenance and troubleshooting, relevant professional knowledge and technical support are required, which increases the use threshold and maintenance costs.

[0006] Finally, in order to ensure the consistency and high quality of the rubbing effect, the rubbing machine driven by the electrical system often needs to be equipped with high-precision sensors and advanced control systems. Although these high-tech components can significantly improve the performance and efficiency of the equipment, they also correspondingly push up the overall cost of the rubbing machine, which may constitute a certain economic burden for users with limited budgets or small manufacturers.

[0030] In addition, in this specific embodiment, if the connection or fixing method between components is not specifically described, the connection or fixing method can be through bolt fixing or pin fixing, or pin shaft connection and the like commonly used in the prior art, and therefore, it will not be described in detail in this embodiment.

[0031] Embodiment 1

[0032] The invention discloses an automatic material receiving and rubbing machine for producing transmission parts, which is used for rubbing the wires. The material consumed in the production of the equipment is wire, specifically metal wire coils. The transmission components produced by the equipment specifically include tooth branches, watch accessories, and transmission shafts and threaded shafts of toys.

[0033] See also Figure 1 , 2 3. The flower rubbing machine includes a material rack for placing raw materials; it also includes a workbench 1 and a processing mechanism 2 arranged on the workbench 1, the processing mechanism 2 is provided with a cutter 21 for wire cutting and a flower rubbing tool 22 for processing the wire after cutting; the flower rubbing machine also includes a feeding mechanism 3 arranged at the front end of the processing mechanism 2; the feeding mechanism 3 includes a first slide rail 31 and a slider 32 slidably arranged on the first slide rail 31, a limit plate 33 is provided on the end of the first slide rail 31 close to the processing mechanism 2, and the limit plate 33 and the slider 32 are respectively provided with a first clamping assembly and a second clamping assembly for fixing the wire; through the precise cooperation of the first clamping assembly and the second clamping assembly, the accurate position of the wire during the processing is ensured, and the flower rubbing accuracy is improved.

[0034] The top surfaces of the limit plate 33 and the slider 32 are at the same horizontal height to ensure the stability of the wire during movement. The first clamping assembly and the second clamping assembly respectively include a first clamping rod 34 and a second clamping rod 35, one end of the first clamping rod 34 and the second clamping rod 35 are swingably connected to one side of the limit plate 33 and the slider 32, and a first spring 36 is provided between the first clamping rod 34 and the limit plate 33 and between the second clamping rod 35 and the slider 32; under the action of the first spring 36, the cooperation between the first clamping rod 34 and the limit plate 33 and the cooperation between the second clamping rod 35 and the slider 32 can fix the wire. The horizontal design of the limit plate 33 and the slider 32, combined with the elastic support of the first spring 36, ensures the stability and reliability of the wire during movement and reduces the processing error caused by the unstable movement of the wire. The reciprocating motion of the slider 32 realizes automatic feeding and resetting of the wire, wherein the first clamping assembly and the second clamping assembly ensure the firm fixation and easy release of the wire through the spring and lever principle.

[0035] The first clamping assembly and the second clamping assembly can both switch between a loose state and a clamping state, and the feeding mechanism 3 is divided into a feeding state and a reset state when in operation; the automatic supply and position adjustment of the wire is realized by switching the states of the first clamping assembly and the second clamping assembly (i.e., a loose state and a clamping state). When the feeding mechanism 3 is in a feeding state, the slider 32 is away from the limit plate 33, the first clamping assembly is in a loose state, and the second clamping assembly is in a clamping state, allowing the slider 32 to move toward the limit plate 33 to realize the feeding of the wire; in the feeding state, the slider 32 is away from the limit plate 33, at which time the second clamping assembly is in a clamping state to fix the wire, and the first clamping assembly is in a loose state, allowing the slider 32 to move toward the limit plate 33 to complete the feeding process of the wire. When the feeding mechanism 3 is in the reset state, the slider 32 is close to the limit plate 33, the first clamping assembly is in the clamping state, and the second clamping assembly is in the loose state, so that the slider 32 moves away from the limit plate 33 to achieve reset; in the reset state, the slider 32 is close to the limit plate 33, at which time the first clamping assembly enters the clamping state to fix the wire, and the second clamping assembly is in the loose state, so that the slider 32 can move away from the limit plate 33 to complete the reset process. The feeding mechanism 3 can cycle back and forth between the feeding state and the reset state; the feeding mechanism 3 can cycle back and forth between the feeding state and the reset state, and through continuous mechanical action, the automatic supply of wire is realized, which greatly improves the production efficiency and automation level of the flower twisting machine; thereby greatly reducing manual intervention, improving production efficiency, and reducing labor intensity.

[0036] Specifically, the feeding mechanism 3 combines mechanical principles with automated operation to achieve automatic feeding and resetting of the wire, ensuring the continuity and efficiency of the processing process. The feeding mechanism 3 not only simplifies the operation process, but also improves the stability and reliability, continuity and efficiency of the equipment.

[0037] See also Figure 1 , 23. The flower rubbing machine also includes a control mechanism 4, which is used to lift the first clamping rod 34 and the second clamping rod 35 to loosen the fixation of the wire; the control mechanism 4 includes a first transmission shaft 41 and a vertical rod 42 arranged on the workbench 1, and the first transmission shaft 41 is provided with a first cam 43, a second cam 44 and a first transmission wheel 45, which converts the rotational motion into linear motion to drive the subsequent linkage mechanism to move. The vertical rod 42 is provided with a first connecting rod 46 and a second connecting rod 47; the first transmission wheel 45 is arranged at the front end of the first transmission shaft 41, and a third connecting rod 48 is rotatably arranged at the eccentric position of the first transmission wheel 45, and the other end of the third connecting rod 48 is rotatably connected to the slider 32 to drive the slider 32 to move on the first slide rail 31; the first transmission wheel 45 is connected to the third connecting rod 48 through an eccentric design, thereby driving the slider 32 to move along the first slide rail 31. The middle parts of the first connecting rod 46 and the second connecting rod 47 are swingably connected to the vertical rod 42, one end of the first connecting rod 46 and the second connecting rod 47 are in contact with the first cam 43 and the second cam 44 respectively, and the other ends of the first connecting rod 46 and the second connecting rod 47 are respectively located below the first clamping rod 34 and the second clamping rod 35. Specifically, the eccentric position refers to a position on the first transmission wheel 45 that is offset from the rotation center. The eccentric mechanism uses this deviation to generate a non-concentric motion trajectory for converting the rotational motion into a reciprocating linear motion or a swinging motion; the eccentric setting of the subsequent second transmission wheel 53 is also the same.

[0038] The slider 32 is also provided with a wire pressing plate 37, and the wire passes through the wire pressing plate 37 and then passes into the first clamping assembly, thereby preventing the wire from shifting when the first clamping assembly is switched to a loose state; effectively preventing the wire from shifting when the clamping assembly is switched to a loose state, thereby ensuring the wire positioning accuracy during the processing process.

[0039] The first connecting rod 46 and the second connecting rod 47 are both provided with a torque spring, and the first connecting rod 46 is controlled by the torque spring to always keep in contact with the first cam 43, and the second connecting rod 47 is controlled by the torque spring to always keep in contact with the second cam 44. The provision of the torque spring ensures that the first connecting rod 46 and the second connecting rod 47 are always in contact with the first cam 43 and the second cam 44, and stable power transmission can be maintained even at high-speed operation, avoiding control misalignment caused by mechanical wear or vibration, and extending the service life of the equipment.

[0040] When the first transmission shaft 41 rotates, under the action of the first cam 43, the first connecting rod 46 pries the first clamping rod 34 to lift, so that the first clamping assembly is switched to a released state; under the action of the second cam 44, the second connecting rod 47 pries the second clamping rod 35 to lift, so that the second clamping assembly is switched to a released state. Specifically, the first connecting rod 46 and the second connecting rod 47 control the lifting action of the first clamping rod 34 and the second clamping rod 35 respectively through contact with the first cam 43 and the second cam 44. When the first transmission shaft 41 rotates, the shapes of the first cam 43 and the second cam 44 change, and the force is transmitted through the first connecting rod 46 and the second connecting rod 47, so that the first clamping rod 34 and the second clamping rod 35 are lifted, thereby realizing the switching of the first clamping assembly and the second clamping assembly between the released state and the clamped state.

[0041] Specifically, the feeding mechanism 3 is driven by the control mechanism 4, so that the feeding process of the equipment requires almost no human intervention, with a high degree of automation, reduced operating difficulty, and improved production efficiency. The control mechanism 4 realizes precise control of wire clamping and release through the combination of cams and connecting rods; it not only improves processing efficiency and finished product quality, ensures the stability of the wire during processing, but also ensures the efficiency and reliability of equipment operation.

[0042] See also Figure 1 , 4 5. The processing mechanism 2 also includes a push block 23 and a vertically arranged slide 24; after the rubbing process is completed, the wire can fall naturally by its own gravity without the need for an additional power device, which not only saves energy, but also simplifies the equipment structure, realizes automatic material collection, and improves the automation level of the production line. The cutter 21 and the rubbing tool 22 are both arranged on the moving end of the slide 24; the slide 24 controls the cutter 21 to cut the wire, and then the push block 23 pushes the cut wire to the rubbing tool 22 to ensure the rubbing processing quality of the wire. The processing mechanism 2 also includes a push rod 25 and a limit block 26, and the limit block 26 and the rubbing tool 22 are arranged adjacent to each other; the push rod 25 pushes the cut wire to the limit block 26, and when the push block 23 pushes the wire to the rubbing tool 22, the rubbing processing position of the wire is ensured to be accurate.

[0043] Specifically, the cutting position of the wire by the cutter 21 is precisely controlled by the vertical movement of the slide 24; then, the push rod 25 pushes the cut wire to the limit block 26, and the limit block 26 adjacent to the rubbing tool 22 ensures that the position of the wire is accurate during the rubbing process, thereby improving the processing accuracy. Finally, the cut wire is pushed to the rubbing tool 22 by the push block 23 for processing. The processing mechanism 2 avoids processing errors caused by wire position deviation through mechanical positioning, thereby ensuring the consistency of the finished product.

[0044] The processing mechanism 2 also includes a second transmission shaft 51 and a push rod 52, and the two ends of the second transmission shaft 51 are respectively provided with a second transmission wheel 53 and a bevel wheel 54; the push rod 25 is arranged on the slide rod 55, and a second slide rail is provided to control the movement of the push rod 25; a fourth connecting rod 56 is rotatably provided at the eccentric part of the second transmission wheel 53, and the other end of the fourth connecting rod 56 is rotatably connected to the slide rod 55; the push rod 25 is driven by the fourth connecting rod 56 to perform the wire feeding operation; the end face of the bevel wheel 54 is inclined; the push block 23 is arranged on the third slide rail; the middle part of the push rod 52 is rotatably arranged on the workbench 1, one end of the push rod 52 contacts the push block 23, and the other end of the push rod 52 contacts the inclined part of the bevel wheel 54; the push rod 52 pushes the push block 23 to operate under the action of the bevel wheel 54, thereby ensuring the position accuracy of the wire during the cutting and rubbing process, and greatly improving the quality and consistency of the finished product. A second spring 57 is provided between the push block 23 and the workbench 1 , and the second spring 57 controls the push rod 52 to always keep in contact with the bevel wheel 54 .

[0045] Specifically, the second transmission shaft 51 passes through the second transmission wheel 53 and the bevel wheel 54 at both ends, and the second transmission wheel 53 drives the fourth connecting rod 56 to drive the push rod 25 to move along the second slide rail to complete the wire feeding task; at the same time, the interaction between the bevel wheel 54 and the push rod 52 causes the push block 23 to move along the third slide rail to accurately push the wire to the rubbing tool 22. The second spring 57 ensures that the push rod 52 and the bevel wheel 54 maintain continuous contact, and the cooperation of the third cam 58 and the swing arm 59, through the elastic control of the reset spring, ensures the stability of the baffle at the bottom of the slide 24, prevents the wire from falling before the rubbing process, and improves the safety and stability of the processing process.

[0046] The processing mechanism 2 also includes a threading plate 27 and a wire placement plate 28, the threading plate 27 has a threading hole 271 and a top thread hole 272 on the same vertical line, and the wire placement plate 28 has a threading groove 281; the threading hole 271 is located above the top thread hole 272, and the threading groove 281 is connected to the top thread hole 272; the wire passes through the threading hole 271, falls into the threading groove 281 after being cut by the cutter 21, and is then pushed to the limit block 26 by the push rod 25 through the top thread hole 272, thereby ensuring the orderly flow and positioning of the wire.

[0047] A third cam 58 is also provided on the second transmission shaft 51; a baffle is provided at the bottom end of the slide 24 (not shown in the figure), and the baffle is used to prevent the wire from falling before the wire is rubbed; the baffle has a swing arm 59, one end of which is swingably provided on the slide 24, and the other end of the swing arm 59 is in contact with the third cam 58; the swing arm 59 is provided with a reset spring, and the reset spring controls the swing arm 59 to always be in contact with the third cam 58.

[0048] Specifically, the baffle is located at the bottom of the slide 24, and its main function is to prevent the wire from falling due to any unexpected factors before the wire is rubbed, thereby ensuring the continuity and safety of the processing process. This is achieved by physical blocking to ensure that the wire will not leave the processing area before the processing is completed. The swing arm 59 of the baffle is in close contact with the third cam 58, so that the baffle can dynamically adjust its position according to the needs of the processing process. The rotational movement of the third cam 58 is converted into the swing of the baffle through contact with the swing arm 59, thereby achieving timely release or blocking of the wire. It ensures precise control of the wire during the processing process and avoids processing errors caused by premature or late release of the wire. The reset spring set on the swing arm 59 ensures that the baffle can be quickly reset after each action is completed and keeps in contact with the third cam 58. It not only improves the processing efficiency, but also ensures the stable operation of the equipment and avoids safety hazards caused by unstable baffle position.

[0049] See also Figure 1 , 6 The wire rubbing machine also includes a straightening mechanism 6 arranged on the workbench 1, and the straightening mechanism 6 is arranged at the front end of the feeding mechanism 3; the straightening mechanism 6 includes a horizontal mounting plate 61, a vertical mounting plate 62 and a straightening wheel 63; the straightening wheel 63 is staggered on the horizontal mounting plate 61 and the vertical mounting plate 62 in a front-to-back manner; the wire can be straightened from multiple angles to ensure that the wire can achieve the required straightness in both the horizontal and vertical directions after passing through the straightening mechanism 6.

[0050] Specifically, when the wire passes through the straightening wheel 63, the straightening wheel 63 will exert a certain pressure and guiding effect on the wire, and eliminate the bending deformation of the wire through the action of mechanical force. The staggered straightening wheels 63 can apply force to the wire from different directions, so as to more comprehensively correct the shape of the wire, and ensure that the wire has reached the ideal straightness before entering the feeding mechanism 3, which provides a good foundation for the subsequent cutting and rubbing processing. The straightening wire has a higher straightness, which helps to improve the accuracy and consistency of the rubbing processing, reduce the processing error caused by the bending of the wire, and ensure the quality of the finished product; at the same time, by pre-straightening the wire, the jitter and deviation of the wire during the processing can be reduced, making the cutting and rubbing operations more stable and improving the processing efficiency. Reducing the bending deformation of the wire reduces the mechanical stress during the processing, helps to protect the cutting tool and the rubbing tool 22, and prolongs the service life of the equipment; and the automated straightening process reduces the dependence on manual intervention, simplifies the operation process, reduces the difficulty of operation, and improves the automation level of the production line.

[0051] Furthermore, the front end of the straightening mechanism 6 is also provided with a cleaning mechanism for cleaning the wire surface; by cleaning the wire in advance, the machine is avoided from stopping for cleaning due to surface impurities during processing, thereby improving production efficiency. A clean wire surface is conducive to improving the rubbing effect, reducing processing defects caused by surface contamination, and ensuring the consistency and aesthetics of the finished product; furthermore, clean processing materials reduce the wear on the rubbing tool 22, prolong the service life of the equipment, and reduce maintenance costs.

[0052] Embodiment 2

[0053] The difference between the rubbing machine in this embodiment and the rubbing machine in the first embodiment is that the third connecting rod 48 and the top rod 25 are further limited in this embodiment, and the specific conditions are as follows:

[0054] The third connecting rod 48 is a telescopic device, specifically a telescopic cylinder and a telescopic rod; the distance between the slider 32 and the limit plate 33 after resetting in the first embodiment is the length of the wire to be cut during feeding. By adjusting the telescopic device to change the length of the third connecting rod 48, and then changing the distance between the slider 32 and the limit plate 33, the length of the wire to be cut during feeding can be controlled. The top rod 25 can be replaced with the wire required for the rubbing process; it can reduce processing interruptions caused by mechanical wear or damage, and improve the stability and continuous production capacity of the rubbing machine.

[0055] Specifically, the introduction of telescopic devices has enabled the rubbing machine to find a balance between meeting personalized customization needs and efficient mass production. For wire processing that requires customized length, the operator can quickly set the required cutting length by adjusting the telescopic device to achieve precise cutting. In mass production, once the standard cutting length is determined, the telescopic device can be locked in a fixed position to ensure that the cutting length of all wires is consistent, improving production efficiency and consistency of finished products. At the same time, the application of telescopic devices and the innovation of wire replacement have jointly improved the processing efficiency and precision of the rubbing machine, ensuring the consistency and high quality of the rubbing effect.

[0056] The technical effects of the present invention are mainly reflected in the following aspects: the control mechanism 4 in the rubbing machine controls the operation of the feeding mechanism 3 through the combination of the cam and the connecting rod, so that the feeding mechanism 3 can cycle back and forth between the feeding state and the reset state; through continuous mechanical action, the automatic supply of wire is realized, which greatly improves the production efficiency and automation level of the rubbing machine, thereby greatly reducing manual intervention, improving production efficiency, and reducing labor intensity; not only improves the processing efficiency and the quality of the finished product, ensures the stability of the wire in the processing process, but also ensures the efficiency and reliability of the equipment operation. The processing mechanism 2 avoids the processing error caused by the position offset of the wire through mechanical positioning, and ensures the consistency of the finished product; specifically, through the vertical movement of the slide 24, the cutting position of the wire by the cutter 21 is accurately controlled; then, the push rod 25 pushes the cut wire to the limit block 26, and the limit block 26 adjacent to the rubbing tool 22 ensures that the position of the wire is accurate during the rubbing process, and improves the processing accuracy; finally, the cut wire is pushed to the rubbing tool 22 by the push block 23 for processing.

[0057] In addition, as common knowledge in the industry, the material rack, slide 24, first transmission shaft 41, second transmission shaft 51, cleaning mechanism, telescopic cylinder and telescopic rod mentioned above; among them, slide 24 is equipped with an independent driving motor; the first transmission shaft 41 and the second transmission shaft 51 can be driven by independent motors, or by the same motor and driven by a gear chain; the cleaning mechanism can be a simple cloth to wipe the surface of the wire. The above is common knowledge; therefore, its principle and structure will not be described in detail.

[0058] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
