Description

Technical Field

[0001] This utility model relates to the field of pantograph carbon sliding plate processing technology, and in particular to a carbon sliding plate bonding centerline positioning device. Background Technology

[0002] In the manufacturing process of carbon strips for high-speed rail pantographs, the bonding and positioning process between the carbon strip and the aluminum support is a critical step affecting product quality and production efficiency. Traditional positioning processes suffer from the following technical challenges:

[0003] 1. Challenges of Reliance on Manual Labor and Precision Control: The current process requires two operators to work together, repeatedly measuring the exposed distance between the two ends of the carbon strip and the aluminum support (with an error controlled within ±0.5mm), and then tightening with a torque wrench before re-inspection. This operation mode, relying on manual experience, is prone to positioning deviations due to differences in measurement techniques, resulting in significant fluctuations in the pass rate. Statistics show that approximately 15% of products require disassembly and rework, significantly increasing labor time and material waste.

[0004] 2. Complexity of processes and efficiency bottlenecks: Traditional processes involve multiple steps, including "positioning → initial measurement → fixing → re-measurement," resulting in long lead times for each product. Especially in high-volume production, the repetitive operations of multiple disassemblies and adjustments reduce production line efficiency by more than 20%, making it difficult to meet the needs of large-scale manufacturing of high-speed rail components.

[0005] 3. Cost and resource waste: The labor cost of the two-person collaboration model is relatively high, and the frequent use of measuring tools (such as micrometers and clamps) accelerates equipment wear and tear. At the same time, positioning errors can lead to a large number of defective products, affecting the factory's efficiency. Utility Model Content

[0029] Example 1

[0030] like Figures 1-5 As shown, this utility model provides a technical solution:

[0031] A carbon slide plate bonding centerline positioning device includes, but is not limited to, a first clamping assembly 1, a second clamping assembly 2, and a fixed base 3; the first clamping assembly 1 and the second clamping assembly 2 are arranged in parallel on the fixed base 3; a first lead screw structure 11 is provided on the first clamping assembly 1; a second lead screw structure 21 is provided on the second clamping assembly 2; the center positions of the first lead screw structure 11 and the second lead screw structure 21 are collinear; and both the first lead screw structure 11 and the second lead screw structure 21 are positive and negative tooth ball screw transmission pairs.

[0032] Based on the above structure, the carbon strip 6 can be clamped and fixed by the first lead screw structure 11 during use, and the carbon strip 6 can be centered during the clamping process. The aluminum support 5 can be clamped and fixed by the second lead screw structure 21, and the aluminum support 5 can be centered during the clamping process. Since the centers of the first lead screw structure 11 and the second lead screw structure 21 are collinear, the carbon strip 6 and the aluminum support 5 can be accurately aligned during the clamping and alignment process, avoiding the process of repeated manual verification and measurement. At the same time, with this device, only one person is needed to complete the alignment operation of the carbon strip 6 and the aluminum support 5, which greatly reduces labor costs.

[0033] As an example, the first clamping assembly 1 may include a first rotating handwheel 12, a first connecting seat 13, and a first auxiliary seat 14; a first lead screw structure is disposed between the first connecting seat 13 and the first auxiliary seat 14, a first bearing seat 15 is disposed in the first connecting seat 13, and a second bearing seat 16 is disposed in the first auxiliary seat 14; the first rotating handwheel 12 is connected to the lead screw end in the first lead screw structure.

[0034] Based on the above structure, the first lead screw structure is rotated by the first rotating handwheel 12, causing the clamping part on the first lead screw structure to move, thereby fixing the aluminum support 5. By setting the first bearing seat 15 and the second bearing seat 16 in the first connecting seat 13 and the first auxiliary seat 14 respectively, the first lead screw structure can rotate stably and smoothly between the first connecting seat 13 and the first auxiliary seat 14, so that the clamping part of the first lead screw always moves in a predetermined direction.

[0035] As an example, the first lead screw structure may include a first positive and negative threaded lead screw 111, a first connecting nut 112 and a second connecting nut 113, a first guide rail 114, a first slider 115 and a second slider 116; the first guide rail 114 is disposed on the fixed base 3 and is arranged parallel to the first positive and negative threaded lead screw 111; the first slider 115 and the second slider 116 are sleeved on the first guide rail 114; the first connecting nut 112 and the second connecting nut 113 are respectively disposed at the front and rear ends of the first positive and negative threaded lead screw 111; the first slider 115 and the first connecting nut 112, as well as the second slider 116 and the second connecting nut 113 are respectively connected as a whole by a first connector.

[0036] Based on the above structure, by rotating the first positive and negative threaded rod 111, the first connecting nut 112 and the second connecting nut 113 can simultaneously move towards each other or move away from each other along the length direction of the first positive and negative threaded rod 111. The first guide rail 114 provides guidance and limiting function for the first slider 115 and the second slider 116, so that the first slider 115 and the second slider 116 can move along a predetermined direction.

[0037] As an example, an abutment bracket 117 for clamping and fixing the aluminum support 5 is provided on the first connector. In this embodiment, the abutment bracket 117 is provided at the connection between the first connector and the first slider 115 and the second slider 116 respectively.

[0038] Based on the above structure, by setting the abutment bracket 117, the aluminum support 5 can be clamped when the first slider 115 and the second slider 116 move together. When clamping the aluminum support 5, the abutment bracket 117 moves away from each other in a synchronous manner, so that the abutment bracket 117 abuts against the inner side wall of the aluminum support 5, thereby fixing and centering the aluminum support 5.

[0039] As an example, a locking element 4 is provided on the first positive and negative threaded screw 111 near the first bearing seat 15;

[0040] The locking component 4 may specifically include a locking handle 41, an abutment rod 42, and a fixing sleeve 43; the fixing sleeve 43 is connected to the side wall of the first bearing seat 15, and the fixing sleeve 43 has a through hole for the first positive and negative threaded rod 111 to pass through. The top of the fixing sleeve 43 has a threaded through hole that mates with the abutment rod 42. The locking handle 41 is connected to the abutment rod 42, and the abutment rod 42 has an external thread.

[0041] Based on the above structure, by rotating the locking handle 41, the abutment rod 42 can be raised and lowered in the threaded hole at the top of the fixed sleeve 43, thereby locking the first positive and negative threaded rod 111. When the first positive and negative threaded rod 111 is rotated to the predetermined position, the locking handle 41 is used to lock the first positive and negative threaded rod 111, thereby achieving precise fixation of the position of the aluminum support 5.

[0042] As an example, the second clamping assembly 2 may include a second rotating handwheel 22, a second connecting seat 23, and a second auxiliary seat 24; a second lead screw structure is disposed between the second connecting seat 23 and the second auxiliary seat 24, a third bearing seat 25 is disposed in the second connecting seat 23, and a fourth bearing seat 26 is disposed in the second auxiliary seat 24; the second rotating handwheel 22 is connected to the end of the lead screw in the second lead screw structure.

[0043] Based on the above structure, the second lead screw structure is rotated by the second rotating handwheel 22, causing the clamping part on the second lead screw structure to move, thereby fixing the carbon strip 6. By setting the third bearing seat 25 and the fourth bearing seat 26 in the second connecting seat 23 and the second auxiliary seat 24 respectively, the second lead screw structure can rotate stably and smoothly between the second connecting seat 23 and the second auxiliary seat 24, so that the clamping part of the second lead screw always moves in the predetermined direction.

[0044] As an example, the second lead screw structure may include a second positive and negative threaded lead screw 211, a third connecting nut 212 and a fourth connecting nut 213, a second guide rail 214, a third slider 215 and a second and fourth slider 216; the second guide rail 214 is disposed on the fixed base 3 and is arranged parallel to the second positive and negative threaded lead screw 211; the third slider 215 and the fourth slider are sleeved on the second guide rail 214; the third connecting nut 212 and the fourth connecting nut 213 are respectively disposed at the front and rear ends of the second positive and negative threaded lead screw 211; the third slider 215 and the third connecting nut 212, as well as the fourth slider and the fourth connecting nut 213 are connected as a whole by a second connector.

[0045] Based on the above structure, by rotating the second positive and negative threaded rod 211, the third connecting nut 212 and the fourth connecting nut 213 can simultaneously move towards each other or move away from each other along the length direction of the second positive and negative threaded rod 211. The second guide rail 214 provides guidance and limiting function for the third slider 215 and the fourth slider, so that the third slider 215 and the fourth slider can move along a predetermined direction.

[0046] As an example, a clamping bracket 217 for clamping and fixing the carbon strip 6 is provided on the second connector. In this embodiment, the clamping bracket 217 is provided at the connection between the second connector and the third slider 215 and the fourth slider, respectively.

[0047] Based on the above structure, by setting the clamping bracket 217, the carbon strip 6 can be clamped when the third slider 215 and the fourth slider move together. When clamping the carbon strip 6, the clamping bracket 217 moves towards each other synchronously, so that the clamping bracket 217 abuts against the outer wall of the carbon strip 6, thereby fixing and centering the carbon strip 6.

[0048] As an example, a locking element 4 is provided on the second positive and negative threaded screw 211 near the third bearing seat 25;

[0049] The locking component 4 may specifically include a locking handle 41, an abutment rod 42, and a fixing sleeve 43; the fixing sleeve 43 is connected to the side wall of the third bearing seat 25, and the fixing sleeve 43 has a through hole for the second positive and negative threaded rod 211 to pass through. The top of the fixing sleeve 43 has a threaded through hole that mates with the abutment rod 42. The locking handle 41 is connected to the abutment rod 42, and the abutment rod 42 has an external thread.

[0050] Based on the above structure, by rotating the locking handle 41, the abutment rod 42 can be raised and lowered in the threaded hole at the top of the fixed sleeve 43, thereby locking the second positive and negative threaded rod 211. When the second positive and negative threaded rod 211 is rotated to the predetermined position, the locking handle 41 is used to lock the second positive and negative threaded rod 211, thereby achieving precise fixation of the carbon strip 6 position.

[0051] As an example, the horizontal position of the abutment bracket 117 is not higher than the horizontal position of the clamping bracket, so that the abutment bracket 117 and the clamping bracket are spatially misaligned.

[0052] Based on the above structure, since the aluminum support 5 fixed by the contact bracket 117 is below the carbon strip 6, the height of the contact bracket 117 needs to be set lower than the clamping bracket, so that the fixing operations of the aluminum support 5 and the carbon strip 6 can be performed more smoothly.

[0053] This solution enables the fixing of aluminum brackets 5 and carbon strips 6 of different specifications and lengths by moving the first and second lead screw structures, making the solution more adaptable.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
