Description

Technical Field

[0001] This utility model relates to the field of shot blasting technology for through shafts, and in particular to a through shaft shot blasting clamping fixture. Background Technology

[0002] As a key component in mechanical transmission systems, through shafts are widely used in automobiles, construction machinery, ships and other fields. Their surface quality directly affects assembly accuracy, wear resistance and service life. Shot blasting is an important process to improve the surface performance of through shafts. Among them, it is important to remove the processed through shaft from the shot blasting equipment while ensuring the integrity of the through shaft.

[0003] Place the lifting plate of the through shaft at the bottom of the processed through shaft, remove the through shaft from the shot blasting equipment, and then move the through shaft to a hollow shelf on one side, taking care to prevent collisions between the through shafts.

[0004] Existing shot blasting clamping fixtures for through shafts cause collisions between the removed through shafts and those on the openwork shelf during the removal process from the shot blasting equipment, resulting in damage to the outer surface of the through shafts. Furthermore, when removing through shafts of different lengths, it is necessary to replace them with compatible workpieces, which is a cumbersome process and affects the shot blasting efficiency of the through shafts. Therefore, a shot blasting clamping fixture for through shafts is proposed. Utility Model Content

A receiving plate is provided at the bottom of the sliding plate. Load-bearing hooks are symmetrically provided at the bottom of the receiving plate. A rubber strip is installed on the upper surface of the load-bearing hooks.

[0010] As a preferred embodiment of the through-shaft shot blasting clamping fixture of this utility model, the adjusting mechanism includes a T-shaped block movably installed inside the receiving plate. A limiting pin is provided on one side of the T-shaped block, and a retaining plate is provided on the outer surface of the limiting pin.

A limiting gasket is provided on one side of the retaining plate, and a spring is provided on one side of the limiting gasket.

[0011] As a preferred embodiment of the through-shaft shot blasting clamping fixture of this utility model, multiple telescopic cylinders are evenly distributed at the bottom of the slide plate, the top of the receiving plate is fixedly connected to the output end of the telescopic cylinder, and slide rods are symmetrically arranged on opposite sides of the two connecting rods.

[0012] As a preferred embodiment of the through-shaft shot blasting clamping fixture of this utility model, a through hole adapted to the slide rod is provided on one side of the telescopic cylinder, the telescopic cylinder is slidably connected to the outside of the slide rod through the through hole, and a motor is installed at one end of the lead screw through the connecting rod.

[0013] As a preferred embodiment of the through-shaft shot blasting clamping fixture of this utility model, the receiving plate has a T-shaped groove adapted to the T-shaped block, the T-shaped block is slidably connected inside the T-shaped groove, the clamping plate is movably clamped on the opposite side of every two limiting blocks, and a round hole adapted to the limiting pin is opened at the center of one side of the clamping plate, and the clamping plate is movably installed on the outside of the limiting pin through the round hole.

[0014] In a preferred embodiment of the through-shaft shot blasting clamping fixture of this utility model, the spring is located outside the limiting pin, a semi-circular fixing plate is symmetrically arranged on one side of the clamping plate, and a pull plate is installed on one side of the semi-circular fixing plate.

The limiting pin is slidably connected inside the sliding hole, and the load-bearing hook is fixedly installed at the center of the bottom of the T-shaped block.

[0016] (III) Beneficial Effects

[0017] This utility model provides a through-shaft shot blasting clamping fixture. It has the following beneficial effects:

[0018] 1. The clamping mechanism allows the processed through-shafts to be removed from one side of the shot blasting equipment and placed in a centralized location. With the cooperation of the lead screw and telescopic cylinder, the load-bearing hooks are first moved to the side of the processed through-shaft. The telescopic cylinder then lifts the two load-bearing hooks upwards, detaching the through-shaft from the shot blasting equipment. The lead screw then moves the through-shaft at the top of the load-bearing hook to one side, slowly placing it on the perforated shelf to prevent collisions between through-shafts and surface damage. Simultaneously, the rubber strips provide some protection to the surface of the through-shafts, facilitating the clamping and removal of the processed through-shafts from the shot blasting equipment and preventing collisions between through-shafts that could affect processing quality.

[0019] 2. By adjusting the mechanism, it is possible to use through shafts of different lengths and remove the processed through shaft from the shot blasting equipment. The clamping plate is pulled outward by the pull plate, and the clamping plate is pulled out from the opposite side of the two limit blocks. The clamping plate is pushed towards the other load-bearing hook by the pull plate, which drives the limit pin to move, thereby moving the T-block towards the other load-bearing hook and adjusting the distance between the two load-bearing hooks. This allows for the use of through shafts of different lengths. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Example 1

[0029] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present invention. This embodiment provides a through-shaft shot blasting clamping fixture, including symmetrically arranged support frames 1, a clamping mechanism 2 on one side of the two support frames 1, and an adjustment mechanism 3 at the bottom of the clamping mechanism 2.

[0030] The clamping mechanism 2 includes connecting rods 201 symmetrically installed on opposite sides of two support frames 1. A lead screw 202 is movably installed on opposite sides of the two connecting rods 201 via a bearing seat. A sliding plate 203 is movably installed on the outer surface of the lead screw 202 via a threaded sleeve. A receiving plate 206 is provided at the bottom of the sliding plate 203. A load-bearing hook 207 is symmetrically provided at the bottom of the receiving plate 206. A rubber strip 208 is installed on the upper surface of the load-bearing hook 207.

[0031] Specifically, multiple telescopic cylinders 205 are evenly distributed on the bottom of the slide plate 203. The top of the receiving plate 206 is fixedly connected to the output end of the telescopic cylinder 205. Two connecting rods 201 are symmetrically arranged with sliding rods 204 on opposite sides. Under the action of the telescopic cylinders 205, the receiving plate 206 can be raised and lowered. After the two load-bearing hooks 207 have finished hooking the through shaft, the through shaft can be raised to a certain height, so that the through shaft is removed from the shot blasting equipment.

[0032] Specifically, the telescopic cylinder 205 has a through hole on one side that is adapted to the slide rod 204. The telescopic cylinder 205 is slidably connected to the outside of the slide rod 204 through the through hole. One end of the lead screw 202 passes through the connecting rod 201 and is equipped with a motor 209. When the slide plate 203 is moved by the lead screw 202, the two slide rods 204 ensure that the slide plate 203 always remains horizontal and can move back and forth stably.

[0033] Furthermore, the operation of motor 209 is controlled. The output end of motor 209 drives lead screw 202 to rotate. Under the action of two slide rods 204, lead screw 202 drives slide plate 203 to move in the direction of motor 209. Then, the telescopic cylinder 205 is controlled to run. The output end of telescopic cylinder 205 pushes the receiving plate 206 downward, so that the bottom of the load-bearing hook 207 passes through the shaft. Then, motor 209 is controlled to run in the opposite direction. Similarly, slide plate 203 drives telescopic cylinder 205 to move, thereby driving receiving plate 206 to move, placing load-bearing hook 207 at the bottom of the shaft. Telescopic cylinder 205 is controlled to run in the opposite direction, lifting receiving plate 206 upward. Receiving plate 206 lifts the shaft upward through load-bearing hook 207, disengaging it from shot blasting equipment. Slide plate 203 is controlled to run again, moving the shaft in the direction of motor 209. Then, telescopic cylinder 205 is controlled to run again, moving receiving plate 206 downward, placing the shaft on the hollow shelf.

[0034] Example 2

[0035] Reference Figure 4 and Figure 5 This is the second embodiment of the present invention, which is based on the previous embodiment. The adjusting mechanism 3 includes a T-shaped block 302 movably installed inside the receiving plate 206. A limiting pin 306 is provided on one side of the T-shaped block 302. A retaining plate 303 is provided on the outer surface of the limiting pin 306. Several limiting blocks 301 adapted to the retaining plate 303 are evenly distributed and symmetrically installed on one side of the receiving plate 206. A limiting pad 308 is provided on one side of the retaining plate 303. A spring 307 is provided on one side of the limiting pad 308.

[0036] Specifically, the receiving plate 206 has a T-shaped groove inside that is adapted to the T-shaped block 302. The T-shaped block 302 is slidably connected inside the T-shaped groove. The locking plate 303 is movably locked onto each pair of limiting blocks 301 on opposite sides. A round hole adapted to the limiting pin 306 is opened at the center of one side of the locking plate 303. The locking plate 303 is movably installed on the outside of the limiting pin 306 through the round hole. After the locking plate 303 is locked into each pair of limiting blocks 301 on opposite sides, it can restrict the movement of the T-shaped block 302, thereby adjusting the distance between the two load-bearing hooks 207. The distance between the two load-bearing hooks 207 is adjusted according to the different lengths of the through shaft.

[0037] Specifically, the spring 307 is located outside the limiting pin 306. A semi-circular fixing plate 304 is symmetrically arranged on one side of the clamping plate 303. A pull plate 305 is installed on one side of the semi-circular fixing plate 304. When the pull plate 305 is pulled outward, the clamping plate 303 can be pulled out from between the two limiting blocks 301, contacting the restriction on the T-shaped block 302, pushing the T-shaped block 302 towards the other side of the load-bearing hook 207, adjusting the distance between the two load-bearing hooks 207, and then the clamping plate 303 is clamped back into the opposite side of the two limiting blocks 301 to restrict the movement of the T-shaped block 302.

[0038] Specifically, the limiting pin 306 is located on one side of the two semi-circular fixing plates 304. A sliding hole adapted to the limiting pin 306 is opened on one side of the receiving plate 206. The limiting pin 306 is slidably connected inside the sliding hole. The load-bearing hook 207 is fixedly installed at the bottom center of the T-shaped block 302. Under the action of the sliding hole of the receiving plate 206, the limiting pin 306 can drive the T-shaped block 302 to move in the receiving plate 206, thereby facilitating the adjustment of the position of the load-bearing hook 207 to adapt to the length of the through shaft.

[0039] Furthermore, manually pull the pull plate 305 outward. The pull plate 305, through the action of the semi-circular fixing plate 304, pulls the clamping plate 303 outward from between the two limiting blocks 301. The clamping plate 303 pushes the limiting pad 308 outward, causing the spring 307 to deform. After the clamping plate 303 is pulled out from the opposite side of the two limiting blocks 301, push the pull plate 305 towards the other load-bearing hook 207, thereby moving the T-shaped block 302. The T-shaped block 302 moves the load-bearing hook 207 at the bottom towards the other load-bearing hook 207. After the two load-bearing hooks 207 are connected by the machined through shaft, align the clamping plate 303 with the opposite side of the corresponding two limiting blocks 301. Release the pulling force applied to the pull plate 305. Under the action of the spring 307, push the limiting pad 308, thereby pushing the clamping plate 303 into the opposite side of the corresponding two limiting blocks 301, thus fixing the T-shaped block 302.

[0040] Working principle: The device is connected to an external power supply and controller via a wiring harness. When the processed through shaft needs to be removed from the shot blasting equipment, the operation of motor 209 is controlled. The output end of motor 209 drives the lead screw 202 to rotate. Under the action of the two slide rods 204, the lead screw 202 drives the slide plate 203 to move in the direction of motor 209. Then, the telescopic cylinder 205 is controlled to operate. The output end of telescopic cylinder 205 pushes the receiving plate 206 downward, so that the bottom of the load-bearing hook 207 passes through the shaft. Then, the motor 209 is controlled to reverse the direction. Similarly, by moving the sliding plate 203 to drive the telescopic cylinder 205, which in turn moves the receiving plate 206, the load-bearing hook 207 is placed at the bottom of the through shaft. The telescopic cylinder 205 is then controlled to reverse, lifting the receiving plate 206 upwards. The receiving plate 206, via the load-bearing hook 207, lifts the through shaft upwards, disengaging it from the shot blasting equipment. The sliding plate 203 is then controlled again to move the through shaft in the direction of the motor 209. Finally, the telescopic cylinder 205 is controlled again to move the receiving plate 206 downwards, placing the through shaft onto the perforated shelf. When shot blasting through shafts of different lengths, the distance between the two load-bearing hooks 207 needs to be adjusted. At this time, manually pull the pull plate 305 outwards. The pull plate 305, through the action of the semi-circular fixing plate 304, pulls the clamping plate 303 outwards from between the two limiting blocks 301. The clamping plate 303 pushes the limiting washer 308 outwards, causing the spring 307 to deform. After the clamping plate 303 is pulled out from the opposite side of the two limiting blocks 301, push the pull plate 305 towards the other load-bearing hook 207, thereby moving the T-shaped block 307. 2. Move the T-block 302 so that the bottom load-bearing hook 207 moves to the other load-bearing hook 207. After the two load-bearing hooks 207 have used the machined through shaft, align the clamping plate 303 with the opposite side of the two corresponding limit blocks 301, release the tension applied to the pull plate 305, and under the action of the spring 307, push the limit pad 308, thereby pushing the clamping plate 303 into the opposite side of the two corresponding limit blocks 301, fix the T-block 302 in this position, move away from it as above, and remove the through shaft from the shot blasting equipment.

[0041] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
