Description

Technical Field

[0001] This utility model relates to the field of connecting rod manufacturing technology, specifically to a connecting rod deburring machine. Background Technology

[0002] Connecting rods are crucial transmission components in mechanical equipment such as engines and compressors. By connecting the piston and crankshaft, they convert the reciprocating linear motion of the piston into the rotational motion of the crankshaft, thereby effectively transmitting power and outputting output. Each end of the connecting rod has a hole of a different size, into which bronze bushings or needle roller bearings are installed, allowing for the insertion of a pin to form a hinge.

[0003] Currently, connecting rods are generally mass-produced using die forging. However, the surface roughness of forged connecting rod blanks is relatively high. Therefore, connecting rod blanks need to undergo precision machining before leaving the factory. In particular, the large and small holes at both ends of the connecting rod must be deburred to ensure surface smoothness and dimensional accuracy.

[0004] However, most existing deburring processes for connecting rods rely on semi-automatic operation. Specifically, workers manually place the connecting rod onto the deburring machine, and after deburring, manually remove it to make room for the next connecting rod. This manual loading and unloading method is not only inefficient but also significantly increases the labor intensity for workers. Prolonged repetitive operations can easily lead to worker fatigue, potentially causing operational errors and affecting the consistency and stability of deburring quality. Furthermore, most existing connecting rod deburring machines can only process one connecting rod at a time, further limiting the improvement of production efficiency.

[0005] Given the aforementioned limitations, it is necessary to improve the existing connecting rod deburring machine to achieve automatic loading and unloading of connecting rods. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] This invention provides a connecting rod deburring machine, which can at least solve the technical problem of how to improve the production efficiency of connecting rods and reduce labor intensity.

[0008] (II) Technical Solution

[0009] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a connecting rod deburring machine, comprising:

[0010] frame;

[0011] The indexing plate is mounted on the frame and has a fixture for accommodating and positioning the connecting rod. The indexing plate is used to transport the connecting rod.

[0012] The feeding device is located on the frame and outside the indexing plate. The feeding device is used to transfer the connecting rod to be deburred onto the fixture.

[0013] The brushing device is mounted on the frame and located outside the indexing plate. The brushing device is used to deburr the walls of the large and small holes of the connecting rod.

[0014] The unloading device is located on the frame and outside the indexing plate. The unloading device is used to transfer the deburred connecting rod out of the fixture.

[0015] Furthermore, the aforementioned fixture includes:

[0016] The base is located on the indexing plate and has a receiving groove for accommodating and limiting the connecting rod;

[0017] The pressure block is slidably mounted on the base. The number of pressure blocks is the same as the number of receiving slots and they are set one-to-one. One end of the pressure block is located in the corresponding receiving slot and is used to abut against the connecting rod in the corresponding receiving slot.

[0018] The elastic element has one end connected to the base and the other end connected to the pressure block. The elastic element has a spring force that drives the pressure block to slide toward the corresponding receiving groove, so that one end of the pressure block slides into the corresponding receiving groove, thereby tightly fixing the connecting rod in the receiving groove.

[0019] In a further configuration, the aforementioned pressure block has a first V-shaped recess at one end within the receiving groove, and a second V-shaped recess symmetrically arranged on the inner wall of the receiving groove. The combination of the first V-shaped recess and the second V-shaped recess is used to guide and limit the position of the connecting rod within the receiving groove.

[0020] Further, the aforementioned feeding device includes:

[0021] The gravity track is mounted on the frame and extends downwards at an incline towards the indexing plate. The gravity track is used to continuously transport the connecting rods one by one.

[0022] The material handling mechanism is mounted on the frame and is used to grab the connecting rod located at the discharge end of the gravity track and remove it from the gravity track.

[0023] The loading mechanism is located on the frame and is used to grab the connecting rod on the material handling mechanism and load it into the receiving slot.

[0024] Furthermore, the aforementioned loading mechanism includes:

[0025] The feeding chuck is used to clamp or release the connecting rod;

[0026] The machine includes a telescopic drive and a rotary drive. The rotary drive is mounted on the frame and is connected to the telescopic drive. The output end of the telescopic drive is connected to the feeding clamp.

[0027] The rotary drive is used to drive the telescopic drive to swing back and forth between the indexing plate and the picking mechanism, so that the loading chuck is positioned relative to the indexing plate or the picking mechanism. The telescopic drive is used to drive the loading chuck to move closer to or away from the indexing plate or the picking mechanism.

[0028] Further, the aforementioned material handling mechanism includes:

[0029] The material chuck is positioned opposite the discharge end of the gravity track and is used to clamp or release the connecting rod.

[0030] The material handling drive unit is mounted on the frame and is connected to the material handling chuck for transmission. The material handling drive unit is used to drive the material handling chuck to move toward or away from the discharge end of the gravity track.

[0031] Further, the aforementioned polishing device includes a large-hole polishing mechanism and a small-hole polishing mechanism, both of which are mounted on the frame. The feeding device, the large-hole polishing mechanism, the small-hole polishing mechanism, and the unloading device are arranged in a ring-shaped interval on the outside of the indexing plate. The large-hole polishing mechanism is used to polish the walls of the large holes in the connecting rod, and the small-hole polishing mechanism is used to polish the walls of the small holes in the connecting rod.

[0032] Furthermore, the aforementioned brushing device also includes at least two pushing mechanisms, which are mounted on the frame. The at least two pushing mechanisms are respectively positioned opposite to the large-hole brushing mechanism and the small-hole brushing mechanism. The pushing mechanisms are used to push the pressure block to slide toward the corresponding receiving groove so as to firmly fix the connecting rod in the receiving groove.

[0033] Further, the aforementioned feeding device includes:

[0034] The feeding conveyor line is located on the frame and is used to continuously convey deburred connecting rods one by one;

[0035] The unloading chuck is used to clamp or release the connecting rod;

[0036] The unloading drive mechanism is mounted on the frame and is connected to the unloading chuck for transmission. The unloading drive mechanism is used to drive the unloading chuck to reciprocate between the indexing plate and the unloading conveyor line.

[0037] (III) Beneficial Effects

[0038] Compared with the prior art, the connecting rod deburring machine provided by this utility model has the following beneficial effects:

[0039] In use, the connecting rod deburring machine provided by this utility model first transfers the connecting rod to the fixture via the feeding device. Then, the indexing plate conveys the connecting rod to a position opposite to the brushing device, which brushes the walls of the large and small holes of the connecting rod to achieve deburring. After deburring, the indexing plate conveys the connecting rod to a position opposite to the unloading device, which transfers the deburred connecting rod out of the fixture. Finally, the indexing plate conveys the empty fixture to a position opposite to the feeding device, so that the feeding device can transfer the connecting rod to be deburred onto the fixture. This process is repeated continuously. It can be seen that this connecting rod deburring machine, through the feeding and unloading devices, can achieve automatic and continuous feeding and unloading of connecting rods, replacing manual labor, thereby effectively improving the production efficiency of connecting rods, reducing labor intensity, and ensuring the consistency and stability of deburring quality.

[0053] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0054] This utility model provides a connecting rod deburring machine to solve the problem of how to improve the production efficiency of connecting rod 7 and reduce labor intensity.

[0055] See Figure 1 and Figure 2 As shown, Figure 1 This is a perspective view of the connecting rod deburring machine in the embodiment. Figure 2 for Figure 1 The enlarged schematic diagram at point A shows that the deburring machine includes a frame 1, an indexing plate 2, a feeding device 3, a brushing device 4, and a discharging device 5.

[0056] The indexing plate 2 is mounted on the frame 1. The indexing plate 2 is equipped with a fixture 21 for accommodating and positioning the connecting rod 7. The indexing plate 2 is used to transport the connecting rod 7.

[0057] The feeding device 3 is installed on the frame 1 and located outside the indexing plate 2. The feeding device 3 is used to transfer the connecting rod 7 to be deburred onto the fixture 21.

[0058] The brushing device 4 is mounted on the frame 1 and located on the outside of the indexing plate 2. The brushing device 4 is used to deburr the walls of the large hole 71 and the small hole 72 of the connecting rod 7.

[0059] The unloading device 5 is mounted on the frame 1 and located outside the indexing plate 2. The unloading device 5 is used to transfer the deburred connecting rod 7 out of the fixture 21.

[0060] When using the connecting rod deburring machine described above, firstly, the feeding device 3 transfers the connecting rod 7 onto the fixture 21. Then, the indexing plate 2 conveys the connecting rod 7 to a position opposite to the polishing device 4, where the polishing device 4 polishes the walls of the large hole 71 and the small hole 72 of the connecting rod 7, thereby achieving the deburring effect. After deburring, the indexing plate 2 conveys the connecting rod 7 to a position opposite to the unloading device 5, which then transfers the deburred connecting rod 7 out of the fixture 21. Finally, the indexing plate 2 conveys the empty fixture 21 to a position opposite to the feeding device 3, so that the feeding device 3 can transfer the connecting rod 7 to be deburred onto the fixture 21. This process is repeated continuously. It can be seen that this connecting rod deburring machine, through the feeding device 3 and the unloading device 5, can achieve automatic and continuous feeding and unloading of the connecting rod 7, replacing manual labor, thereby effectively improving the production efficiency of the connecting rod 7, reducing labor intensity, and ensuring the consistency and stability of the deburring quality.

[0061] The indexing plate 2 mentioned above can also be replaced by existing conveying mechanisms such as conveyor belts, conveyor chains, or transplanting mechanisms.

[0062] See Figure 2 As shown, in one embodiment of the fixture 21, the fixture 21 includes a base 211, a pressure block 212, and an elastic member 213. The base 211 is mounted on the indexing plate 2 by means of screwing or welding, and the base 211 has a receiving groove 2111 for accommodating and limiting the connecting rod 7. The pressure block 212 is slidably connected to the base 211, and the number of pressure blocks 212 and the receiving grooves 2111 are the same and correspond one-to-one. One end of the pressure block 212 is located in the corresponding receiving groove 2111 and is used to abut against the connecting rod 7 in the corresponding receiving groove 2111. One end of the elastic member 213 is connected to the base 211 by means of bonding or abutment, and the other end is connected to the pressure block 212 by means of bonding or abutment. The elastic element 213 has a spring force that drives the pressure block 212 to slide toward the corresponding receiving groove 2111, so that one end of the pressure block 212 slides into the corresponding receiving groove 2111, thereby tightly fixing the connecting rod 7 in the receiving groove 2111. It can be seen that the fixture 21 can accommodate connecting rods 7 of different models and sizes through the receiving groove 2111, effectively improving the applicability of the connecting rod deburring machine. While the connecting rod 7 is installed in the receiving groove 2111, the pressure block 212 can automatically position the connecting rod 7 under the elastic force of the elastic element 213, so that the indexing plate 2 can stably convey the connecting rod 7 to the brushing device 4 and the unloading device 5 in sequence, thereby facilitating the smooth operation of subsequent automatic deburring and automatic unloading.

[0063] See Figure 2As shown, based on the above embodiment, the pressure block 212 has a first V-shaped recess 2121 at one end located within the receiving groove 2111, and the inner wall of the receiving groove 2111 has second V-shaped recesses 2112 symmetrically distributed with the first V-shaped recess 2121. The first V-shaped recess 2121 and the second V-shaped recess 2112 are combined to guide and limit the position of the connecting rod 7 within the receiving groove 2111. Because the connecting rod 7 is clearance-fitted with the receiving groove 2111, the pressure block 212 and the elastic element 213 can only fix the approximate position of the connecting rod 7 in the receiving groove 2111. However, in order to ensure the consistency of the position of the connecting rod 7 in the receiving groove 2111 within the same batch, the symmetrical first V-shaped recess 2121 and the second V-shaped recess 2112 can guide and restrict the position of the connecting rod 7 in the receiving groove 2111, so that the symmetrical center lines of the connecting rods 7 in the same batch are all located on the same straight line within the receiving groove 2111. In this way, the deburring effect of the connecting rod deburring machine can be effectively improved.

[0064] See Figure 1 As shown, in one embodiment of the feeding device 3, the feeding device 3 includes a gravity track 31, a picking mechanism 32, and a loading mechanism 33. The gravity track 31 is mounted on the frame 1 by means of screwing or welding, and extends downwards at an incline towards the indexing plate 2. The gravity track 31 is used to continuously convey the connecting rods 7 one by one. The picking mechanism 32 is mounted on the frame 1 and is used to grab the connecting rods 7 located at the discharge end of the gravity track 31 and remove them from the gravity track 31. The loading mechanism 33 is mounted on the frame 1 and is used to grab the connecting rods 7 on the picking mechanism 32 and load them into the receiving groove 2111. Thus, when feeding the connecting rod 7, the workers first place the connecting rods 7 in batches on the gravity track 31. The gravity track 31 uses the weight of the connecting rods 7 themselves to drive the connecting rods 7 downward along the gravity track 31 to the discharge end of the gravity track 31. No additional material picking drive 322 is needed, which greatly saves the cost of the drive equipment. Then, the material picking mechanism 32 grabs the connecting rods 7 located at the discharge end of the gravity track 31 and leaves the gravity track 31. The loading mechanism 33 grabs the connecting rods 7 on the material picking mechanism 32 and loads them into the receiving slot 2111 of the corresponding fixture 21 and transfers them to the fixture 21 of the indexing plate 2. This realizes the automatic and continuous feeding of the connecting rods 7, thereby effectively improving the production efficiency of the connecting rods 7 and reducing labor intensity.

[0065] See Figure 3 As shown, Figure 3This is a schematic diagram of the indexing plate and loading mechanism in one embodiment. In one implementation of the loading mechanism 33, the loading mechanism 33 includes a loading clamp 331, a telescopic drive member 332, and a rotary drive member 333. The loading clamp 331 is used to clamp or release the connecting rod 7. The rotary drive member 333 is mounted on the frame 1 by screwing or welding and is connected to the telescopic drive member 332. The output end of the telescopic drive member 332 is connected to the loading clamp 331 by screwing or welding. The rotary drive member 333 drives the telescopic drive member 332 to reciprocate between the indexing plate 2 and the picking mechanism 32, so that the loading clamp 331 is positioned relative to the indexing plate 2 or the picking mechanism 32. The telescopic drive member 332 drives the loading clamp 331 to move closer to or away from the indexing plate 2 or the picking mechanism 32. Thus, when the rotary drive 333 drives the telescopic drive 332 to swing to a position opposite to the picking mechanism 32, the telescopic drive 332 drives the loading chuck 331 to move toward the picking mechanism 32, so that the loading chuck 331 can clamp the connecting rod 7 on the picking mechanism 32, thereby realizing the gripping of the connecting rod 7 on the picking mechanism 32; after gripping the connecting rod 7, the telescopic drive 332 first drives the loading chuck 331 to move away from the picking mechanism 32, and then the rotary drive 333 drives the telescopic drive 332 to swing to a position opposite to the indexing plate 2, so that the loading chuck 331 can move with the indexing plate during the swing. 2. Interference occurs; finally, the telescopic drive 332 drives the loading chuck 331 to move toward the indexing plate 2. At the same time, the rotation drive 333 drives the telescopic drive 332 to swing toward the compression elastic member 213, so that one end of the connecting rod 7 is inserted into the receiving groove 2111 at an angle. The connecting rod 7 pushes the pressure block 212 to slide and compress the elastic member 213 until the connecting rod 7 is fully inserted into the receiving groove 2111. The loading chuck 331 releases the connecting rod 7. At the same time, the telescopic drive 332 drives the loading chuck 331 to move away from the indexing plate 2. In this way, the connecting rod 7 can be installed on the above-mentioned fixture 21.

[0066] The aforementioned loading chuck 331 can use an existing gripper cylinder, and the aforementioned telescopic drive component 332 can use an existing telescopic cylinder or telescopic pole, or other linear displacement drive mechanism. Thus, when the telescopic drive component 332 extends, it drives the loading chuck 331 closer to the indexing plate 2 or the material handling mechanism 32; conversely, when the telescopic drive component 332 retracts, it drives the loading chuck 331 away from the indexing plate 2 or the material handling mechanism 32. The aforementioned rotary drive component 333 can use an existing rotary motor or rotary cylinder, or other rotary drive mechanism, and its output end is connected to the telescopic drive component 332 by screwing or welding.

[0067] See Figure 4 As shown, Figure 4This is a partial structural diagram of the gravity track and the material handling mechanism in one embodiment. In one implementation of the material handling mechanism 32, the mechanism includes a material handling clamp 321 and a material handling drive 322. The material handling clamp 321 is positioned opposite to the discharge end of the gravity track 31 and is used to clamp or release the connecting rod 7. The material handling drive 322 is mounted on the frame 1 by screwing or welding and is connected to the material handling clamp 321. The material handling drive 322 drives the material handling clamp 321 to move towards or away from the discharge end of the gravity track 31. It can be seen that the material handling drive 322 and the material handling clamp 321 work together to grasp the connecting rod 7 at the discharge end of the gravity track 31.

[0068] The aforementioned material handling chuck 321 can use an existing gripper cylinder, and the aforementioned material handling drive 322 can use an existing telescopic cylinder or telescopic pole, or other linear displacement drive mechanism. Its output end is connected to the material handling chuck 321 by screwing or welding. Thus, when the material handling drive 322 extends, it can drive the material handling chuck 321 to move toward the discharge end of the gravity track 31. Conversely, when the material handling drive 322 shortens, it can drive the material handling chuck 321 to move away from the discharge end of the gravity track 31.

[0069] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, based on any of the above embodiments, the fixture 21 has at least two receiving slots 2111. The number of gravity rails 31, loading chucks 331, unloading chucks 321, and receiving slots 2111 are the same and are arranged in a one-to-one correspondence. The output end of the telescopic drive member 332 is connected to several loading chucks 331 by means of screwing or welding. The output end of the unloading drive member 322 is connected to several unloading chucks 321 by means of screwing or welding. In this way, the loading device 3 can simultaneously load all receiving slots 2111 of the same fixture 21, further effectively improving the production efficiency of the connecting rod 7.

[0070] See Figure 1 and Figure 4As shown, based on the embodiment of the feeding device 3 including a gravity track 31, a material handling mechanism 32, and a loading mechanism 33, the feeding device 3 may further include a blocking mechanism 34. The blocking mechanism 34 is located upstream of the discharge end of the gravity track 31 and includes a baffle 341 and a baffle drive member 342. The baffle drive member 342 is mounted on the frame 1 by screwing or welding, and its output end is connected to the baffle 341 by screwing or welding. The baffle drive member 342 drives the baffle 341 to move into or out of the gravity track 31. When the baffle 341 moves into the gravity track 31, it can prevent the upstream connecting rod 7 from moving to the discharge end of the gravity track 31. Thus, the feeding device 3 can control the discharge of the connecting rod 7 on the gravity track 31 through the blocking mechanism 34.

[0071] The aforementioned baffle drive 342 can use existing linear displacement drive mechanisms such as telescopic cylinders or telescopic poles. Thus, when the baffle drive 342 extends, it can drive the baffle 341 into the gravity track 31; conversely, when the baffle drive 342 shortens, it can drive the baffle 341 out of the gravity track 31.

[0072] See Figure 1 As shown, in one embodiment of the polishing device 4, the polishing device 4 includes a large-hole polishing mechanism 41 and a small-hole polishing mechanism 42. Both the large-hole polishing mechanism 41 and the small-hole polishing mechanism 42 are mounted on the frame 1, and the feeding device 3, the large-hole polishing mechanism 41, the small-hole polishing mechanism 42, and the unloading device 5 are sequentially arranged in a ring-like pattern on the outer side of the indexing plate 2. The large-hole polishing mechanism 41 is used to polish the wall of the large hole 71 of the connecting rod 7, and the small-hole polishing mechanism 42 is used to polish the wall of the small hole 72 of the connecting rod 7. Thus, the polishing device 4 can deburr the walls of the large hole 71 and the small hole 72 of the connecting rod 7 through the large-hole polishing mechanism 41 and the small-hole polishing mechanism 42.

[0073] See Figure 5 As shown, Figure 5The diagram illustrates the structure of the large-hole brushing mechanism and the pressing mechanism in this embodiment. Based on the above embodiment, the brushing device 4 further includes at least two pressing mechanisms 43. The pressing mechanisms 43 are mounted on the frame 1 via screws or welding. At least two pressing mechanisms 43 are positioned opposite to the large-hole brushing mechanism 41 and the small-hole brushing mechanism 42, respectively. The pressing mechanisms 43 push the pressure block 212 towards the corresponding receiving groove 2111 to secure the connecting rod 7 tightly against the receiving groove 2111. Thus, when the indexing plate 2 transports the fixture 21 to a position opposite to the large-hole brushing mechanism 41 or the small-hole brushing mechanism 42, the pressing mechanism 43 pushes the pressure block 212 of the fixture 21 towards the corresponding receiving groove 2111 to reinforce the connecting rod 7 within the receiving groove 2111. This effectively prevents the connecting rod 7 from shifting during the deburring process, thus avoiding any impact on the deburring effect of the large-hole brushing mechanism 41 and the small-hole brushing mechanism 42.

[0074] The aforementioned pushing mechanism 43 can use existing linear displacement drive mechanisms such as telescopic cylinders or telescopic poles. In this way, when the pushing mechanism 43 extends, it can push the corresponding pressure block 212 to slide; conversely, when the pushing mechanism 43 shortens, it can release the corresponding pressure block 212.

[0075] See Figure 1 and Figure 5 As shown, in one embodiment of the large-hole polishing mechanism 41 and the small-hole polishing mechanism 42, both the large-hole polishing mechanism 41 and the small-hole polishing mechanism 42 include a brush head 411, a rotating mechanism 412, and a position adjusting mechanism 413. The output end of the rotating mechanism 412 is connected to the brush head 411 by means of screwing or welding, etc. The rotating mechanism 412 is used to drive the brush head 411 to rotate, so as to polish the hole wall of the large hole 71 or the small hole 72. The position adjusting mechanism 413 is mounted on the frame 1 by means of screwing or welding, etc., and the output end of the position adjusting mechanism 413 is connected to the rotating mechanism 412 by means of screwing or welding, etc. The position adjusting mechanism 413 is used to drive the rotating mechanism 412 to move toward or away from the indexing plate 2, so as to insert the brush head 411 into the large hole 71 or the small hole 72. In this way, the brush head 411, the rotating mechanism 412 and the position adjustment mechanism 413 work together to brush the walls of the large hole 71 or the small hole 72 to achieve the effect of deburring.

[0076] The diameter of the brush head 411 of the large hole brushing mechanism 41 and the small hole brushing mechanism 42 can be set according to the actual diameter of the large hole 71 and the small hole 72 of the connecting rod 7. The diameter of the brush head 411 of the large hole brushing mechanism 41 must be slightly larger than the diameter of the large hole 71 of the connecting rod 7, and the diameter of the brush head 411 of the small hole 72 must be slightly larger than the diameter of the small hole 72 of the connecting rod 7.

[0077] The number of brush heads 411 and receiving slots 2111 are the same, and they are arranged in a one-to-one correspondence. The rotating mechanism 412 can use existing rotary motor-belt gear transmission or rotary motor-gear transmission mechanisms, and its output end is connected to several brush heads 411 by screwing or welding. Thus, if the fixture 21 is provided with at least two receiving slots 2111, both the large-hole brushing mechanism 41 and the small-hole brushing mechanism 42 can simultaneously brush and deburr the connecting rod 7 in all receiving slots 2111 of the same fixture 21, further effectively improving the production efficiency of the connecting rod 7.

[0078] See Figure 1 and Figure 2 As shown, in one embodiment of the unloading device 5, the unloading device 5 includes an unloading conveyor line 51, an unloading clamp 52, and an unloading drive mechanism 53. The unloading conveyor line 51 is mounted on the frame 1 by means of screwing or welding, and is used to continuously convey deburred connecting rods 7 one by one. The unloading clamp 52 is used to clamp or release the connecting rods 7. The unloading drive mechanism 53 is mounted on the frame 1 and is drivenly connected to the unloading clamp 52. The unloading drive mechanism 53 is used to drive the unloading clamp 52 to reciprocate between the indexing plate 2 and the unloading conveyor line 51. In this way, the unloading drive mechanism 53 and the unloading clamp 52 cooperate to transfer the deburred connecting rods 7 from the indexing plate 2 to the unloading conveyor line 51, and the unloading conveyor line 51 continuously outputs the deburred connecting rods 7 one by one from the deburring machine, thereby realizing the automatic unloading of the connecting rods 7.

[0079] The aforementioned position adjustment mechanism 413 and the aforementioned unloading drive mechanism 53 can use existing three-axis moving mechanisms. The three-axis moving mechanism can adjust the position of the brush head 411 or the unloading clamp 52 so that the brush head 411 is opposite to the large hole 71 or small hole 72 of the connecting rod 7 in the receiving groove 2111, and the unloading clamp 52 is opposite to the handle 73 of the connecting rod 7 in the receiving groove 2111 or opposite to the unloading conveyor line 51. The three-axis moving mechanism can also drive the brush head 411 or the unloading clamp 52 to move up and down so as to complete the deburring, gripping and unloading actions of the connecting rod 7. Alternatively, the aforementioned position adjustment mechanism 413 and unloading drive mechanism 53 can use existing two-axis moving mechanisms. The two-axis moving mechanism only needs to drive the brush head 411 or the unloading clamp 52 to move along the symmetrical center line of the connecting rod 7 in the corresponding receiving groove 2111, so that the brush head 411 is positioned opposite the large hole 71 or small hole 72 of the connecting rod 7, and the unloading clamp 52 is positioned opposite the handle 73 of the connecting rod 7, which greatly saves the cost of the driving equipment. However, the feeding end of the unloading conveyor line 51 needs to be located on the symmetrical center line of the connecting rod 7 in the corresponding receiving groove 2111; and the two-axis moving mechanism also needs to be able to drive the brush head 411 or the unloading clamp 52 to move up and down.

[0080] The aforementioned unloading chuck 52 can use existing gripper cylinders, and the aforementioned unloading conveyor line 51 can be replaced by existing continuous conveying mechanisms such as conveyor belts and conveyor chains. The number of the aforementioned unloading chucks 52 and receiving slots 2111 are the same, and they are arranged in a one-to-one correspondence. Thus, if the fixture 21 has at least two receiving slots 2111, the unloading device 5 can unload materials from all receiving slots 2111 of the same fixture 21 simultaneously, further effectively improving the production efficiency of the connecting rod 7.

[0081] See Figure 2 As shown, based on the above embodiment, the connecting rod deburring machine also includes an air blowing device 6. The air blowing device 6 is installed at the output end of the unloading drive mechanism 53 or on the unloading chuck 52 by means of screwing or welding. Thus, when the unloading chuck 52 is opposite to the receiving groove 2111, or when the unloading chuck 52 grips the connecting rod 7, the air blowing device 6 blows air onto the connecting rod 7, which can remove debris or dust and other particulate matter from the connecting rod 7, thereby further improving the deburring effect of the connecting rod 7.

[0082] The aforementioned air blowing device 6 can use existing air blowing equipment.

[0083] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
