Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of clamping tool structures, in particular to a clamping tool for gear surface electroplating. Background Art
[0002] When a batch of non-standard gears are produced in the workshop, the process requires electroplating a layer of nickel on the outer surface of the gears. The nickel layer plays a role in extending the service life of the gears. In the electroplating workshop, the main methods are as follows: Figures 1 and 2 The clamping fixture shown is used in conjunction with an electroplating tank to electroplate gears. The clamping fixture includes a horizontal plate 2, and a plurality of vertical plates 3 are fixed on the bottom surface of the horizontal plate 2 at intervals along its length direction. A support rod 4 is fixed on the front end surface of the lower end of each vertical plate 3, and handles 5 are fixed on the top surface of the horizontal plate 2 and at its left and right ends.
[0003] The method by which workers use the clamping fixture in conjunction with the electroplating tank to electroplate the gear is as follows:
[0004] S1. A worker installs a gear 1 to be electroplated on each support rod 4, that is, hangs the inner top wall of the center hole 6 of the gear 1 on the support rod 4, as shown in FIG. Figure 3 As shown;
[0005] S2, the worker supports the left and right sides of the horizontal plate 2 on the left and right side walls of the plating tank 7 respectively, as shown in FIG. Figure 4 As shown, ensure that each gear 1 is immersed in the electroplating solution of the electroplating tank 7, so that the clamping fixture is installed on the electroplating tank 7;
[0006] S3. The worker clamps the negative electrode of the power supply on the horizontal plate 2, immerses the positive electrode of the power supply into the electroplating solution of the electroplating tank 7, and then turns on the power. After a period of electroplating, a layer of nickel is electroplated on the outer surface of each gear 1;
[0007] S4. The worker turns off the power supply and then removes the clamping tool from the electroplating tank 7. After removing it, the worker removes the gear 1 from the support rod 4, thereby obtaining the required gear 1.
[0008] However, although this clamping fixture can cooperate with the electroplating tank 7 to electroplate the gear 1, in actual operation, it still has the following technical defects:
[0009] I. During the electroplating process in step S3, since the electroplating liquid in the electroplating tank 7 is in a flowing state, the flowing electroplating liquid will drive the gear 1 to shake relative to the stationary support rod 4, causing the inner top wall of the gear 1 to be worn by the support rod 4. However, the process requires that the inner wall of the gear 1 is not damaged by any wear, thereby reducing the production quality of the gear 1.
[0010] II. The cross plate 2 is supported on the electroplating tank 7. Therefore, when the flowing electroplating liquid hits the gear 1, the gear 1 will push the cross plate 2 to move on the top surface of the electroplating tank 7 under the push of the fluid, causing the gear 1 to collide with the inner wall of the electroplating tank 7 and be damaged, thereby further reducing the production quality of the gear 1.
[0011] Therefore, there is an urgent need for a clamping tool that can prevent gear shaking and greatly improve the quality of gear production. Utility Model Content

[0039] The present invention is further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following:
[0040] like Figures 5 to 10 As shown, a clamping fixture for gear surface electroplating, which includes a horizontal plate 2, on the left and right ends of the horizontal plate 2 are respectively welded a left support plate 8 and a right support plate 9, the left support plate 8 is provided with a locking assembly 10 for locking and fixing the horizontal plate 2 on the electroplating tank, a plurality of vertical plates 3 are welded on the bottom surface of the horizontal plate 2 and spaced along its length direction, a support rod 4 is welded on the front end surface of the lower end of each vertical plate 3, a screw rod 11 extending below the horizontal plate 2 is rotatably installed in the horizontal plate 2, a handle 17 is fixedly connected to the top of the screw rod 11, a nut 12 is threadedly connected to the threaded section of the screw rod 11, a lifting plate 13 is welded to the outside of the nut 12, a plurality of fixing plates 14 corresponding to the vertical plates 3 are also welded on the top surface of the lifting plate 13 and along its length direction, a pressure rod 15 is welded on the front end surface of the upper end of each fixing plate 14;
[0041] Two guide rods 16 are fixed to the bottom surface of the horizontal plate 2. These guide rods 16 extend downward through the left and right ends of the lifting plate 13, respectively. Guide holes are defined on both ends of the lifting plate 13, and both guide rods 16 extend downward through these two guide holes. A bearing seat is fixed to the top surface of the horizontal plate 2, and the screw rod 11 is rotatably mounted within the bearing seat. Handles 5 are welded to the top surface of the horizontal plate 2, at both its left and right ends, to facilitate workers in handling the horizontal plate 2.
[0042] The locking assembly 10 includes a locking screw 18 rotatably installed in the left support plate 8, and a polished rod fixed on the inner end surface of the left support plate 8. A pressure block 19 is threadedly connected to the threaded section of the locking screw 18, and the pressure block 19 is mounted on the polished rod; a through hole is opened in the pressure block 19, and the pressure block 19 is mounted on the polished rod through the through hole.
[0043] The working process of this utility model is as follows:
[0044] S1. The worker sets a gear 1 to be electroplated between each support rod 4 and its opposite pressure rod 15. Figure 11 As shown, at this time, the inner top wall of the center hole 6 of the gear 1 is just suspended on the support rod 4;
[0045] S2. The worker manually rotates the handle 17, which drives the screw 11 to rotate. The nut 12 moves linearly downward along the screw 11. The nut 12 drives the lifting plate 13 to move linearly downward along the guide rod 16. The lifting plate 13 drives the various fixed plates 14 on it to move downward synchronously. The fixed plate 14 drives the pressure rod 15 to move downward. When the handle 17 is rotated a certain number of times, the pressure rod 15 just rests on the inner bottom wall of the center hole 6 of the gear 1, thereby fixing the gear 1 between the support rod 4 and the pressure rod 15. Figure 12 As shown;
[0046] S3. The worker supports the left and right sides of the horizontal plate 2 on the left and right side walls of the electroplating tank 7 respectively, and ensures that each gear 1 is immersed in the electroplating solution of the electroplating tank 7, and at the same time ensures that the right support plate 9 is against the right end surface of the electroplating tank 7, as shown in FIG. Figure 13 As shown;
[0047] S4. The worker turns the locking screw 18. Under the thread cooperation between the locking screw 18 and the pressing block 19, the pressing block 19 moves to the right. After a certain number of turns, the pressing block 19 presses against the left end surface of the electroplating tank 7, thereby fixing the horizontal plate 2 on the top surface of the electroplating tank 7. Figure 14 As shown;
[0048] S5. The worker clamps the negative electrode of the power supply on the horizontal plate 2, immerses the positive electrode of the power supply into the electroplating solution of the electroplating tank 7, and then turns on the power. After a period of electroplating, a layer of nickel is electroplated on the outer surface of each gear 1;
[0049] S6. Removal of gear 1: The worker turns off the power supply and then loosens the locking screw 18 to separate the pressure block 19 from the electroplating tank 7. The worker then removes the horizontal plate 2 from the electroplating tank 7 and removes the electroplated gear 1 from the electroplating tank 7. After removal, the worker rotates the handle 17 in the opposite direction to move the nut 12 upward along the screw rod 11. The nut 12 drives the lifting plate 13 upward, the lifting plate 13 drives the fixing plate 14 upward, and the fixing plate 14 drives the pressure rod 15 upward, and the pressure rod 15 separates from the inner bottom wall of the gear 1. Finally, the worker removes the gear 1 from the support rod 4.
[0050] S7. Repeat steps S1 to S6 multiple times to continuously electroplate multiple batches of gears 1.
[0051] Among them, it can be seen from S2 that when the gear 1 is in the electroplating process, since the gear 1 is fixed between the support rod 4 and the pressure rod 15, the electroplating liquid in the electroplating tank 7 in a flowing state will not drive the gear 1 to shake relative to the stationary support rod 4, effectively avoiding the inner top wall of the gear 1 being worn and damaged by the support rod 4. It can be seen that this clamping fixture is better than the Figures 1 to 4The clamping fixture shown plays a good role in protecting the gear 1, thereby greatly improving the production quality of the gear 1.
[0052] From steps S3 to S4, it can be seen that because the right support plate 9 rests against the right end surface of the electroplating tank 7, and the pressure block 19 is pressed against the left end surface of the electroplating tank 7 under the threaded connection force of the locking screw 18, the cross plate 2 is always fixed to the top surface of the electroplating tank 7. Therefore, when the flowing electroplating solution impacts the gear 1, the gear 1 cannot drive the cross plate 2 to move on the top surface of the electroplating tank 7, thereby effectively preventing the gear 1 from colliding with the inner wall of the electroplating tank 7 and being damaged, further improving the production quality of the gear 1.
[0053] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
