Description

Technical Field

[0001] The utility model belongs to the technical field of anode plate processing for hydrometallurgical zinc electrolysis, and particularly relates to a positioning and grinding platform. Background Art

[0002] During the production process of the conductive crossbeam of the anode plate, it is necessary to pour lead water into the copper bar in the shaping cavity. And in order to strengthen the combination of copper and lead, the copper bar needs to be tinned in advance. At present, after the casting of the crossbeam copper bar is completed, the processing of the casting nozzle, flash burrs, conductive contacts, etc. all adopt the method of manual positioning and operation. For example, the nozzle is chopped with a kitchen knife, the flash burrs are scraped with a small knife, and the contacts are double-sided ground with a angle grinder. Moreover, it also involves the situations of handling and turning over, with high labor intensity and low operation efficiency. In addition, the existing operation platform cannot adapt to the external dimensions of the crossbeam after tinning and the crossbeam after lead casting (crossbeams in different processing stages) at the same time, and has poor practicability; and during the moving process of tinning the copper bar, the position of the crossbeam lifting lug often shifts, and there is no effective correction mechanism on the existing operation platform. Therefore, it is necessary to improve the positioning and grinding operation platform in the production process of the existing conductive crossbeam. Summary of the Utility Model

[0003] The utility model aims at the above problems and provides a positioning and grinding platform with accurate crossbeam positioning, stable clamping, capable of correcting the position of the crossbeam lifting lug, convenient operation, low labor intensity, high operation efficiency and strong applicability.

The tinned crossbeam is positioned and placed in the narrow positioning groove of the crossbeam positioning chuck. Then, after the crossbeam clamping mechanism presses and fixes the tinned crossbeam, the position of the crossbeam lug on the crossbeam is corrected by using the lug positioning and clamping mechanism. At the same time, the wider, lead-cast crossbeam can be positioned and placed in the wide positioning groove of the crossbeam positioning chuck, so that after the crossbeam clamping mechanism presses and fixes the lead-cast crossbeam, the casting nozzle is cut and the crossbeam profile is trimmed by using a nozzle cutting tool and a grinding tool.

The driving end of the upper part of the crossbeam clamping cylinder is connected to a crossbeam clamping swing rod, and a crossbeam clamping pressing block is arranged at the front end of the crossbeam clamping swing rod. The crossbeam clamping swing rod is driven to reciprocate by the crossbeam clamping cylinder, and then the crossbeam clamping pressing block at the front end of the crossbeam clamping swing rod is used to press and fix the crossbeam positioned and placed in the crossbeam positioning chuck, so as to facilitate subsequent operations such as correcting the position of the crossbeam lug, cutting the casting nozzle, and trimming the crossbeam profile.

[0007] The lug positioning and clamping mechanism includes a bidirectional telescopic cylinder fixedly arranged on the crossbeam placement platform. The cylinder expansion rods on both sides of the bidirectional telescopic cylinder are arranged along the extension direction of the crossbeam, and cylinder rod connection blocks are respectively arranged at the ends of the cylinder expansion rods on both sides. Lug positioning and clamping blocks are arranged above the upper parts of the cylinder rod connection blocks and above the bidirectional telescopic cylinder. A lug positioning space is arranged between the two lug positioning and clamping blocks. Beam avoidance notches with sizes larger than the width of the crossbeam are respectively arranged on the upper sides of the lug positioning and clamping blocks. When the tinned crossbeam is placed on the crossbeam positioning chuck, the position of the crossbeam lug on the crossbeam is corrected by using the lug positioning and clamping blocks arranged on the cylinder rod connection blocks at the ends of the cylinder expansion rods on both sides. And when the lead-cast crossbeam is placed on the crossbeam positioning chuck, the part of the crossbeam lug is positioned and clamped by the lug positioning and clamping blocks on both sides, which is convenient for cutting and grinding.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] According to Figures 1 to 6Describe in detail the specific structure of the present utility model. The positioning and grinding platform includes a platform bearing support frame 1. A horizontally arranged crossbeam placement platform 2 is provided on the upper part of the platform bearing support frame 1. At both ends on the upper side of the crossbeam placement platform 2, there are respectively provided crossbeam positioning blocks 3 for positioning and placing the conductive crossbeams during the processing. The crossbeam positioning block 3 is composed of a block base body 9. The lower part of the block base body 9 is fixedly connected to the upper side of the crossbeam placement platform 2. An opening is provided in the upper part of the block base body 9. At the opening of the block base body 9, a narrow positioning groove 10 for placing the crossbeam 20 after tinning and a wide positioning groove 11 for placing the crossbeam 22 after lead casting are successively arranged from bottom to top, and the wide positioning groove 11 is communicated with the narrow positioning groove 10. Further, the crossbeam 20 after tinning is positioned and placed in the narrow positioning groove 10 of the crossbeam positioning block 3. After the crossbeam clamping mechanism 4 clamps the crossbeam 20 after tinning, the position of the crossbeam lug 21 on the crossbeam is corrected by the lug positioning and clamping mechanism 5. At the same time, the wider crossbeam 22 after lead casting can be positioned and placed in the wide positioning groove 11 of the crossbeam positioning block 3. After the crossbeam clamping mechanism 4 clamps the crossbeam 22 after lead casting, the casting sprue 23 is cut and the crossbeam shape is trimmed by the sprue cutting tool and the grinding tool.

[0018] On the rear side of the block base body 9 of the crossbeam positioning block 3, there are respectively provided crossbeam clamping mechanisms 4. The crossbeam clamping mechanism 4 includes a crossbeam clamping cylinder 12 vertically arranged on the rear side of the block base body 9. The driving end at the upper part of the crossbeam clamping cylinder 12 is connected to the crossbeam clamping swing rod 13. And a crossbeam clamping pressing block 14 is provided at the front end of the crossbeam clamping swing rod 13. At the same time, the crossbeam clamping pressing block 14 of the crossbeam clamping mechanism 4 is located above the corresponding crossbeam positioning block 3 (the crossbeam placed). Thus, the crossbeam clamping swing rod 13 is driven to reciprocate by the crossbeam clamping cylinder 12. Further, the crossbeam placed in the crossbeam positioning block 3 is clamped by the crossbeam clamping pressing block 14 at the front end of the crossbeam clamping swing rod 13, so as to facilitate the subsequent operations such as the position correction of the crossbeam lug 21, the cutting of the casting sprue 23 and the trimming of the crossbeam shape.

[0019] Between the crossbeam placed on the platform 2 and the crossbeam positioning blocks 3 at both ends, there are two sets of symmetrically arranged lug positioning and clamping mechanisms 5. The lug positioning and clamping mechanism 5 is composed of a bidirectional telescopic cylinder 15 fixedly arranged on the crossbeam placing platform 2, and the cylinder telescopic rods on both sides of the bidirectional telescopic cylinder 15 are arranged along the extension direction of the crossbeam. Moreover, at the ends of the cylinder telescopic rods on both sides, there are respectively cylinder rod connection blocks 16; above the upper part of the cylinder rod connection block 16 and above the bidirectional telescopic cylinder 15, there are lug positioning and clamping blocks 17; there is a lug positioning space 19 between the two lug positioning and clamping blocks 17. On the upper side of the lug positioning and clamping block 17, there are also crossbeam avoidance notches 18 with a size larger than the width of the crossbeam. Then, when the tinned crossbeam 20 is placed on the crossbeam positioning block 3, the lug positioning and clamping blocks 17 arranged on the cylinder rod connection blocks 16 at the ends of the cylinder telescopic rods on both sides are used to correct the position of the crossbeam lug 21 on the crossbeam. And when the lead-cast crossbeam 22 is placed on the crossbeam positioning block 3, the parts of the crossbeam lug 21 are positioned and clamped by the lug positioning and clamping blocks 17 on both sides, which is convenient for cutting and grinding.

[0020] At one end of the crossbeam placing platform 2, there is a side positioning block 7 for positioning the end of the conductive crossbeam, and at the rear side of the middle part of the crossbeam placing platform 2, there is also a rear positioning block 6. Thus, the end of the conductive crossbeam is positioned by the side positioning block 7, and the rear side of the middle part of the tinned crossbeam 20 placed on the crossbeam positioning block 3 is positioned by the rear positioning block 6. Moreover, when the lead-cast crossbeam 22 is placed on the crossbeam positioning block 3, the rear positioning block 6 located below the lead-cast crossbeam 22 (because the lead-cast crossbeam 22 is placed at a higher position on the crossbeam positioning block 3 and the width of the beam is large, so the rear positioning block 6 will be located below the crossbeam at this time) is used to assist in supporting the lead-cast crossbeam 22, improving the use reliability of the device. In addition, between the two sets of lug positioning and clamping mechanisms 5 and at the front side of the middle part of the crossbeam placing platform 2, there is a blanking chute 8 for connecting with the receiving port of the receiving vehicle.

[0021] When the positioning and grinding platform is in use, the tinned crossbeam 20 can be positioned and placed on the crossbeam positioning blocks 3 on both sides and in the narrow positioning groove 10 with a lower position. The side positioning block 7 is used to position the end of the tinned crossbeam 20, and the rear positioning block 6 is used to position the rear side of the middle part of the tinned crossbeam 20 placed on the crossbeam positioning block 3. Then, the crossbeam clamping cylinder 12 is used to drive the crossbeam clamping swing rod 13 to swing, so as to press and fix the tinned crossbeam 20 in the narrow positioning groove 10 through the crossbeam clamping pressing block 14 at the front end of the crossbeam clamping swing rod 13. After that, the lug positioning and clamping mechanism 5 is used to correct the position of the crossbeam lug 21 on the crossbeam by means of the lug positioning and clamping blocks 17 provided on the cylinder rod connecting blocks 16 at the ends of the cylinder telescopic rods on both sides. Subsequently, the corrected tinned crossbeam 20 is placed into the shaping cavity for lead water casting.

[0022] After casting is completed, the lead-cast crossbeam 22 is positioned and placed on the crossbeam positioning blocks 3 on both sides and in the wide positioning groove 11 with a higher position (after lead casting, the width of the crossbeam increases). The side positioning block 7 is used to position the end of the lead-cast crossbeam 22, the rear positioning block 6 located below is used to assist in supporting the lead-cast crossbeam 22, and the lug positioning and clamping blocks 17 on both sides are used to position and clamp the part of the crossbeam lug 21. After that, the crossbeam clamping mechanism 4 is used to press and fix the lead-cast crossbeam 22, and then the casting sprue 23 is cut and the crossbeam profile is trimmed by means of the sprue cutting tool and the grinding tool. The cut casting sprue 23 will slide down through the blanking chute 8 into the receiving cart.
