Description

Technical Field

[0001] The invention relates to the technical field of grinding wheel coating, and in particular to a rotary in-situ in-and-out chemical plating device without a fixed attachment point. Background Art

[0002] The base material of the coated grinding wheel is generally made of cemented carbide. First, electric spark grinding and diamond grinding are used to miniaturize the grinding wheel base, and then electroplating, chemical plating and chemical vapor deposition (CVD) are used to grow a layer of diamond-containing coating on the surface of the base.

[0003] The coating bonding strength of chemically plated diamond grinding wheels is generally better than that of electroplating, and the chemically plated Ni-P coating is dense and non-porous, and its hardness, wear resistance and corrosion resistance are better than those of electroplated nickel, which increases the service life of the diamond grinding wheel.

[0004] When performing chemical plating, the grinding wheel needs to be completely immersed in the chemical plating solution. The existing chemical plating equipment generally uses a lifting device to sink one or more groups of grinding wheels to be plated into the chemical plating solution. After the plating is completed, the grinding wheels are lifted and removed. The plating process of two adjacent groups of grinding wheels requires two steps of taking and placing the plated grinding wheels and installing the uncoated grinding wheels, which reduces the plating efficiency.

[0005] In the prior art, two symmetrical flexible transmission racks are arranged, and the transmission chain passes through the plating tank containing the chemical plating solution, driving the grinding wheel carried on it to pass through the plating tank. Although the efficiency is improved, since the plating tank as a whole is a cavity with an opening facing upward, the movement trajectory of the transmission rack needs to be downward first and then upward. It is inconvenient to constrain the movement trajectory of the transmission rack in the plating tank. The long flexible transmission chain will continuously bring out the chemical plating solution from the plating tank during circulation, causing the plating solution to be lost. The rack is immersed in the chemical plating solution for a long time, which may react with the chain, affecting the service life of the chain or the working accuracy of the coating. Moreover, in this type of method, when the workpiece is plated, due to the presence of a clamping position or a supporting position, the coating in this area is often affected. Summary of the invention

[0006] The purpose of the present invention is to provide a rotary in-situ in-and-out chemical plating device without a fixed attachment point, so as to solve the technical problems that the grinding wheel chemical plating device in the prior art has low plating efficiency, it is inconvenient to constrain the moving trajectory of the transmission rack in the plating solution tank, the chain will continuously bring out the chemical plating solution from the plating solution tank during circulation, causing the plating solution to be lost, and the rack is immersed in the chemical plating solution for a long time, which may react with the chain and affect the service life or working accuracy of the chain.

[0007] In order to solve the above technical problems, the present invention specifically provides a rotary in-situ chemical plating device without fixed attachment points, comprising a plating solution tank for containing chemical plating solution and a rotary frame installed above the plating solution tank through a bracket, and a material unloading transmission device and a material loading transmission device are arranged in sequence on the same side of the rotary frame and along the rotation direction of the rotary frame. The material unloading transmission device and the material loading transmission device load and unload materials to the rotary frame according to the frequency cycle of the rotation of the rotary frame, so that the grinding wheel group enters the plating solution tank in sequence to complete the chemical plating;

[0008] The wheel rotating frame includes a shaft rotatably connected to the bracket, and a plurality of evenly distributed rotating arms are symmetrically mounted on the shaft about the center point of the shaft end face, and a hook for supporting the grinding wheel set is mounted at the other end of each rotating arm through a rotating shaft;

[0009] Among them, the loading and conveying device delivers the grinding wheel group to the hook according to the frequency period of the rotation of the wheel frame, and the hook supports the grinding wheel group by flipping its posture and rotates to drive the grinding wheel group into the plating solution pool. After completing the chemical plating, the hook transfers the grinding wheel group to the unloading and conveying device that moves according to the frequency period of the rotation of the wheel frame by flipping its posture.

[0010] Furthermore, the hook is configured to be V-shaped, and one end of the hook is rotatably connected to the rotating arm via a rotating shaft.

[0011] Furthermore, the grinding wheels in the grinding wheel group are movably mounted on the hook via a rotating bracket;

[0012] The rotary support comprises a rotary rod which passes through the centers of a plurality of grinding wheels in sequence, and adjacent grinding wheels are separated by a movable isolation ring, and a limit clip group is fixedly installed at both ends of the rotary rod, and the hook is located in the limit clip group and can move freely to perform posture flipping.

[0013] Furthermore, the grinding wheel group enters the plating solution pool as the wheel rotating frame rotates, so that the grinding wheel group rotates around the wheel rotating rod and is lifted by the wheel rotating rod in a form without a fixed attachment point.

[0014] Furthermore, a stabilizing block is fixedly provided on the plating solution pool at the side of the loading and conveying device, and the stabilizing block is used to support one end of the hook away from the rotating arm so that the hook does not shake when the grinding wheel group is dropped by the loading and conveying device.

[0015] Furthermore, a smooth curved surface is provided on a side of the stabilizing block facing the rotatable frame;

[0016] The starting end of the smooth curved surface produces a relative upward deflection on the hook loaded with the grinding wheel group, and along with the rotation of the rotating arm, the deflection angle of the smooth curved surface to the hook gradually decreases, so that the hook does not shake when leaving the smooth curved surface.

[0017] Furthermore, the loading and unloading transmission device and the unloading and unloading transmission device have the same structure, and both include a transmission roller and two symmetrically arranged transmission toothed belts;

[0018] The loading and unloading transmission device and the unloading and unloading transmission device are both arranged between the rotating arms at both ends of the shaft.

[0019] Furthermore, the starting end of the unloading transmission device is located within the rotation track of the grinding wheel group, so that the coated grinding wheel group can be transferred from the hook to the transmission toothed belt of the unloading transmission device during the rotation of the wheel rotating frame.

[0020] Furthermore, the end of the feeding and conveying device overlaps with a point or a section of the rotation track of the hook wheel, so that the feeding and conveying device can drop the grinding wheel group at its end onto the cyclically rotating hook.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The present invention supports the grinding wheel group by rotating a hook installed on a rotating arm, and realizes high-precision constraint of a rotating path with a simple structure. The hook is always opened upward, so that the unloading transmission device and the loading transmission device can load and unload materials to the rotating frame according to the frequency period of rotation of the rotating frame. At the same time, in the process of the rotating frame rotating to drive the grinding wheel group into the plating liquid pool, the rotating rod of the grinding wheel group rotates, so that the grinding wheel group has no fixed attachment point, and further the grinding wheel group can be plated in a comprehensive and indiscriminate manner. The rotating frame cooperates with the loading transmission device and the unloading transmission device to automatically complete the loading, plating and unloading of the grinding wheel group, and the loading, plating and unloading work are carried out simultaneously, thereby improving the efficiency of plating.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 5 As shown, the present invention specifically provides a rotary in-situ chemical plating device without a fixed attachment point, comprising:

[0033] The plating solution tank 1 is used to contain the chemical plating solution, and its upper end is open;

[0034] The wheel rotating frame 2 is installed above the plating liquid pool 1 through a bracket, and is used to mount the grinding wheel group 5 and rotate;

[0035] The unloading transmission device 3 and the loading transmission device 4 are located on the same side of the rotary frame 2 and are arranged sequentially along the rotation direction of the rotary frame 2. The unloading transmission device 3 and the loading transmission device 4 can load and unload materials to the rotary frame 2 according to the frequency cycle of the rotation of the rotary frame 2, so that the grinding wheel group 5 sequentially enters the plating solution pool 1 to complete chemical plating;

[0036] The wheel rotating frame 2 includes a shaft 201 rotatably connected to the bracket, and a plurality of evenly distributed rotating arms 202 are symmetrically mounted on the shaft 201 about the center point of the shaft end face, and a hook 203 for supporting the grinding wheel group 5 is mounted on the other end of each rotating arm 202 through a rotating shaft;

[0037] Among them, the loading and conveying device 4 delivers the grinding wheel group 5 to the hook 203 according to the frequency period of rotation of the wheel frame 2. The hook 203 supports the grinding wheel group 5 by flipping its posture and rotates to drive the grinding wheel group 5 into the plating solution pool 1. After completing the chemical plating, the hook 203 transfers the grinding wheel group 5 to the unloading and conveying device 3 which moves according to the frequency period of rotation of the wheel frame 2 by flipping its posture.

[0038] The working process of the above-mentioned grinding wheel chemical plating device is as follows:

[0039] The wheel frame 2 is driven to rotate by the driving mechanism, and the wheel frame 2 will drive the multiple groups of rotating arms 202 installed thereon and the hooks 203 installed on the rotating arms 202 to rotate synchronously.

[0040] When the wheel frame 2 rotates, since the wheel frame 2 carries the grinding wheel group 5 through the hook 203, and the hook 203 is installed on the rotating arm 202 through the rotating shaft, under the action of gravity, the hook 203 always opens upward, on the one hand to ensure that the grinding wheel group 5 will not overturn, and on the other hand, it is convenient for the loading and conveying device 4 to deliver the grinding wheel group 5 to the hook 203 according to the frequency cycle of the rotation of the wheel frame 2. After the chemical plating is completed, the hook 203 transfers the grinding wheel group 5 to the unloading and conveying device 3 that moves according to the frequency cycle of the rotation of the wheel frame 2 by flipping its posture; that is, the unloading and conveying device 3 and the loading and conveying device 4 can load and unload materials to the wheel frame 2 according to the frequency cycle of the rotation of the wheel frame 2.

[0041] The unloading conveying device 3 is in front and the loading conveying device 4 is in the back. The unloading conveying device 3 first removes the coated grinding wheel group 5 from the hook 203, and the loading conveying device 4 then puts the uncoated grinding wheel group 5 onto the unloaded hook 203, and then enters the plating solution pool 1 along with the wheel rotating frame 2.

[0042] The wheel rotating frame 2 cooperates with the unloading transmission device 3 and the loading transmission device 4 to automatically and continuously complete the loading, coating and unloading of the grinding wheel group 5.

[0043] Manually, the grinding wheel set 5 to be coated is placed at the starting end of the loading and conveying device 4, and the coated grinding wheel set 5 at the end of the unloading and conveying device 3 is removed.

[0044] Moreover, as the rotating frame 2 rotates, the plated grinding wheel set 5 will leave the chemical plating solution. Since the rotating frame 2 is arranged above the plating solution pool 1, the chemical plating solution remaining on the plated grinding wheel set 5 will drip into the plating solution pool 1, playing the role of plating solution recovery.

[0045] By rotating the hook 203 mounted on the rotating arm 202 to carry the grinding wheel set 5, the hook 203 is always opened upward, so that the unloading transmission device 3 and the loading transmission device 4 can easily load and unload materials to the rotary frame 2 according to the frequency cycle of the rotary frame 2.

[0046] The rotating frame 2 cooperates with the loading and unloading transmission device 4 and the unloading transmission device 3 to automatically complete the loading and unloading of the grinding wheel group 5, and the cyclic rotation of the rotating frame 2 can make the coating work and the loading and / or unloading work be carried out simultaneously, thereby improving the efficiency of the coating of the grinding wheel 502.

[0047] The device brings the grinding wheel group 5 into the plating tank 1 through the circular rotation of the wheel frame 2. Compared with the flexible rack, the rotation path of the wheel frame 2 can be easily constrained, and there is no need to arrange path constraining components in the plating tank 1. The wheel frame 2 itself has a simple structure and does not require high precision. There is no need to worry about long-term immersion in the chemical plating solution affecting the precision. As the wheel frame 2 rotates, the grinding wheel group 5 that has completed the coating will leave the chemical plating solution. Since the wheel frame 2 is arranged above the plating tank 1, the chemical plating solution remaining on the coated grinding wheel group 5 will drip into the plating tank 1, which plays a role in plating solution recovery.

[0048] Furthermore, the hook 203 is configured to be V-shaped, the groove in the middle of the V-shape is the mounting position of the grinding wheel 502, and one end of the hook 203 is rotatably connected to the rotating arm 202 via a rotating shaft.

[0049] The reason for setting it into a V-shape is to eliminate any obstruction at the opening, so that the grinding wheel set 5 can enter the hook 203 more easily.

[0050] Furthermore, the starting end of the unloading transmission device 3 is located within the rotation track of the grinding wheel group 5, so that the coated grinding wheel group 5 can be transferred from the hook 203 to the transmission toothed belt 3402 of the unloading transmission device 3 during the rotation of the wheel frame 2.

[0051] Furthermore, the end of the loading and conveying device 4 overlaps with a point or a section of the rotation trajectory of the hook 203. Preferably, during the rotation of the rotating frame 2, the end of the V-shaped hook 203 that is not connected to the rotating arm 202 can be flush with or slightly lower than the highest point of the end of the transmission toothed belt 3402, so that the loading and conveying device 4 can drop the grinding wheel group 5 at its end onto the hook 203.

[0052] Furthermore, since one end of the hook 203 is rotatably connected to the rotating arm 202, when the feeding and conveying device 4 drops the grinding wheel group 5 onto the hook 203, under the action of the grinding wheel group 5's own gravity and the impact potential energy it carries, the hook 203 will inevitably produce a reciprocating swing / shake that first deflects downward and then deflects upward, and there is a risk of throwing the grinding wheel group 5 out, that is, the grinding wheel group 5 may slip off the hook 203. In particular, in order to make it easier for the grinding wheel group 5 to enter the hook 203, when the hook 203 is set to a V-shape, the probability of the grinding wheel group 5 slipping off the hook 203 is greater.

[0053] Therefore, a stabilizing block 6 is fixedly provided on the side of the loading and conveying device 4 on the plating bath 1 , and the stabilizing block 6 is used to support one end of the hook 203 away from the rotating arm 202 , so that the hook 203 does not shake when the grinding wheel group 5 is placed by the loading and conveying device 4 .

[0054] The reasons for no shaking are:

[0055] When the stabilizing block 6 is in contact with the unloaded hook 203, the hook 203 does not have a relative deflection. When the grinding wheel group 5 is placed on the hook 203, the hook 203 cannot deflect downward due to the obstruction of the stabilizing block 6. This is equivalent to the stabilizing block 6 causing a relative upward deflection of the hook 203 mounted with the grinding wheel group 5, thereby avoiding the shaking of the hook 203 when being hit by the grinding wheel group 5.

[0056] Furthermore, although the above-mentioned stabilizing block 6 can prevent the hook 203 from shaking when being hit by the grinding wheel group 5, it is considered that the hook 203 will be separated from the stabilizing block 6 as the rotating arm 202 rotates. Since the stabilizing block 6 produces a relatively upward deflection of the hook 203 mounted with the grinding wheel group 5, the deflection amplitude is relatively large. Therefore, when the hook 203 is separated from the stabilizing block 6, the hook 203 will still be deflected downward by a large amplitude at one time under the gravity of the grinding wheel group 5, and there is still a risk of being unhooked.

[0057] To this end, the present invention sets the side of the stabilizing block 6 facing the wheel frame 2 as a smooth curved surface 7, the starting end of the smooth curved surface 7 produces a relative upward deflection to the hook 203 loaded with the grinding wheel group 5, and the end of the smooth curved surface 7 has no deflection to the hook 203 loaded with the grinding wheel group 5, and with the rotation of the rotating arm 202, the deflection angle of the smooth curved surface 7 to the hook 203 gradually decreases, completely eliminating the shaking, so that the hook 203 does not shake when it leaves the smooth curved surface 7.

[0058] The following is combined with Figure 5To further explain, at the node where the feeding transmission device 4 puts the grinding wheel group 5 to the hook 203, the end of the V-shaped hook 203 that is not connected to the rotating arm 202 conflicts with the smooth curved surface 7, so that the V-shaped hook 203 is not in a naturally hanging state, that is, it is slightly deflected in the clockwise direction ( Figure 2 The clockwise direction in the figure) is equivalent to that both ends of the V-shaped hook 203 are fixed, and even if the grinding wheel group 5 is put in, it will not shake, so that the grinding wheel group 5 can be stably put on the V-shaped hook 203;

[0059] As the wheel frame 2 rotates, the degree of deflection of the smooth curved surface 7 on the V-shaped hook 203 becomes smaller and smaller, until the V-shaped hook 203 moves to the end of the smooth curved surface 7, and the smooth curved surface 7 does not deflect the hook 203 at all, that is, the hook 203 is in a naturally hanging state at this time. Since the deflection of the hook 203 by the smooth curved surface 7 gradually disappears, the hook 203 will not shake when it leaves the smooth curved surface 7, thereby preventing the hook 203 from shaking and causing the grinding wheel group 5 to fall off.

[0060] The method for making the smooth curved surface 7 is as follows: a scanner can be used to record the movement curve of the hook 203 that is not connected to the rotating arm 202 and rotates a certain distance after the hook 203 carries the grinding wheel group 5 and there is no smooth curved surface 7 to support it, that is, in a naturally hanging state. A smooth curve with gradually smaller deflection can be obtained by rotating slightly clockwise with the end of the curve as the center.

[0061] Furthermore, the grinding wheels 502 in the grinding wheel group 5 are movably mounted on the hook 203 through a rotating bracket;

[0062] The rotary support includes a rotary rod 501 that passes through the centers of multiple grinding wheels 502 in sequence, and adjacent grinding wheels are separated by a movably mounted isolation ring 503. Limiting clip groups are fixedly installed at both ends of the rotary rod 501, and the hook 203 can be inserted into the gap of the limiting clip group, and the gap width is greater than the thickness of the hook 203, so that the hook 203 can move in the gap of the limiting clip group, that is, the hook 203 is located in the limiting clip group and can move freely to perform posture flipping.

[0063] The grinding wheel set 5 enters the plating solution pool 1 as the wheel frame 2 rotates, so that the grinding wheel set 5 rotates around the wheel rod 501 and is lifted by the wheel rod 501 without a fixed attachment point.

[0064] When the wheel frame rotates and drives the grinding wheel group into the plating solution pool, the wheel rod of the grinding wheel group rotates, so that the grinding wheel group has no fixed attachment point, and further enables the grinding wheel group to be fully and indiscriminately plated.

[0065] When the hook 203 passes through the unloading and conveying device 3 , the grinding wheel set 5 is carried by the unloading and conveying device 3 , and as the wheel rotating frame 2 rotates, the grinding wheel set 5 gradually detaches from the hook 203 .

[0066] When the hook 203 passes through the feeding and conveying device 4, the feeding and conveying device 4 puts the grinding wheel group 5 to the hook 203, and the two hooks 203 are clamped into the limit clip groups at both ends of the grinding wheel group 5 to stably support the grinding wheel group 5 and prevent the grinding wheel group 5 from axial separation.

[0067] One specific arrangement of the limit clip set is: two nuts 504 are arranged at intervals at both ends of the rotating rod 501, and the inner nut 504 is used to fix the outermost isolation ring 503 or the grinding wheel 502. It is best that the isolation ring 503 is located at the outermost side to avoid friction between the nut 504 and the grinding wheel 502 when tightening the nut 504;

[0068] The rod body between the inner nut 504 and the outer nut 504 can cooperate with the mounting position of the grinding wheel 502 on the rotating frame 2 to install the grinding wheel set 5 on the rotating frame 2. That is, there is a gap between the inner nut 504 and the outer nut 504, and this gap can be placed on the mounting position of the grinding wheel 502. The nuts 504 on both sides of the gap can play a limiting role to prevent the grinding wheel set 5 from moving away from the mounting position of the grinding wheel 502 in the axial direction of the rotating rod 501.

[0069] Furthermore, considering that during the rotation of the wheel frame 2, the position of the hook 203 is switched back and forth on both sides of the rotating arm 202, and the two ends of the grinding wheel group 5 are respectively placed on two symmetrically arranged hooks 203, in order to avoid the rotating arm 202 from interfering with the hook 203 and the grinding wheel group 5, the hook 203 needs to be set on the inner side of the rotating arm 202.

[0070] The unloading conveying device 3 and the loading conveying device 4 are located on the same side of the rotary frame 2. This arrangement can make the end of the unloading conveying device 3 and the starting end of the loading conveying device 4 on the same side and close to each other, which is convenient for workers to load and unload materials.

[0071] The loading transmission device 4 and the unloading transmission device 3 have the same structure, both including a transmission toothed belt 3402 and a transmission roller 3401. Since the transmission toothed belt 3402 cooperates with the rotating rod 501 of the grinding wheel group 5, and the diameter of the grinding wheel 502 is much larger than the diameter of the rotating rod 501, in order to avoid interference between the transmission toothed belt 3402 and the grinding wheel 502, it is necessary to set the transmission toothed belt 3402 into two symmetrical strands, so that a gap is created between the loading transmission device 4 and the unloading transmission device 3.

[0072] If the transmission roller 3401 also interferes with the grinding wheel 502, it is necessary to separate the transmission rollers 3401 located at the starting end and the end of the transmission toothed belt 3402, that is, to convert the entire long roller into two short rollers; accordingly, the transmission device that originally only required one servo motor to drive now requires two servo motors to drive so that the two transmission toothed belts 3402 can operate synchronously.

[0073] The loading and unloading transmission device 4 and the unloading and unloading transmission device 3 are both arranged between the rotating arms 202 at both ends of the shaft 201. When the wheel frame 2 passes through the unloading and unloading transmission device 3, the end of the grinding wheel group 5 on the hook 203 will contact the transmission toothed belt 3402 and be supported by the transmission toothed belt 3402, so that the grinding wheel group 5 is transferred from the hook 203 to the transmission toothed belt 3402 to complete the handover and unloading of the grinding wheel group 5.

[0074] The end of the feeding and conveying device 4 overlaps with a point or a section of the rotation track of the hook 203 , so that the feeding and conveying device 4 can drop the grinding wheel set 5 at its end onto the cyclically rotating hook 203 .

[0075] When the hook 203 passes through the feeding transmission device 4, the servo motor drives the transmission roller 3401 to rotate, so that the transmission toothed belt 3402 rotates, and the grinding wheel group 5 to be coated at the end of the transmission toothed belt 3402 is dropped onto the hook 203 to complete the feeding.
