Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting equipment, in particular to a structural part pre-treatment shot blasting equipment. Background Art

[0002] Shot blasting equipment usually consists of a sealed shot blasting chamber, which is equipped with a shot blasting wheel and shots. The structural parts are placed in the chamber and the shots are projected at high speed onto the surface of the structural parts through the shot blasting wheel to remove impurities such as oxide scale, dirt, paint, etc. on the surface, thereby achieving the effect of cleaning and roughening the surface.

[0003] The Chinese patent "A Forging Shot Blasting Equipment" authorization announcement number "CN219685114U" uses a motor, a main rod and a hanging rod to achieve rotational shot blasting of the workpiece, thereby improving the shot blasting cleaning effect of the workpiece.

[0004] However, the shot blasting equipment cannot perform shot blasting on the bottom of the workpiece, resulting in a dead angle in the shot blasting of the workpiece, thereby affecting the shot blasting effect of the workpiece.

[0005] Therefore, a structural part pre-treatment shot blasting device is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the present invention is to provide a structural part pre-treatment shot blasting device in order to solve the above problems, thereby improving the problem of dead angles in the shot blasting of workpieces.

[0007] The utility model achieves the above-mentioned purpose through the following technical solutions: a structural part pre-treatment shot blasting device, comprising: a processing box, the top of the processing box is connected to the shot blasting machine, the inner wall of the processing box is fixedly connected to the support plate, and the top of the support plate is provided with an adjustment mechanism; wherein, the adjustment mechanism includes a first motor arranged on the top of the support plate, the output shaft of the first motor is fixedly connected to the placement table, the top of the support plate is provided with a gear, the surface of the gear is meshed with two racks, the surface of the rack is fixedly connected to a driven frame, the inner wall of the driven frame is rotatably connected to a clamping block, and the bottom end of the placement table is provided with a driving assembly.

[0008] Preferably, the drive assembly includes an electric push rod fixedly connected to the bottom end of the placement table, the telescopic end of the electric push rod is fixedly connected to the protective frame, both ends of the gear are rotatably connected to the inner wall of the protective frame, the surface of the rack is slidably connected to the inner wall of the protective frame, the bottom end of the gear is fixedly connected to a second motor, and one end of the clamping block is fixedly connected to a third motor. The gear, rack, clamping block and third motor are used to clamp and flip the structural member, thereby ensuring that the shot blasting equipment can perform a comprehensive shot blasting treatment on the structural member, improving the shot blasting effect of the shot blasting equipment on the structural member. The electric push rod and the protective frame are used to adjust the upward movement of the structural member, ensuring that the structural member does not touch the placement table during flipping, and adjusting the position of the structural member is simple.

[0009] Preferably, the tops of the placement table and the support plate are both provided with through holes, which enable the steel balls ejected by the shot blasting machine to fall into the inner wall of the treatment box for filtration before being subjected to the shot blasting operation again, thus avoiding the inconvenience of later processing of steel balls trapped on the support plate and the placement table.

[0010] Preferably, a follower block is fixedly connected to the bottom end of the placement platform, and a ball bearing is rollingly connected to the inner wall of the follower block. The surface of the ball bearing is rollingly connected to the top of the support plate, and the surface of the follower frame is slidingly connected to the inner wall of the follower block. The ball bearing and the follower block are used to limit the placement platform during rotation, ensuring the stability of the placement platform during rotation.

[0011] Preferably, scrapers are fixedly connected to both sides of the driven block, and the bottoms of the scrapers are in contact with the top of the support plate. The scrapers are used to scrape the steel balls on the support plate, ensuring that the balls are not blocked by the steel balls during rolling.

[0012] Preferably, a blocking frame is fixedly connected to the surface of the driven frame, and the surface of the third motor is fixedly connected to the inner wall of the blocking frame. The blocking frame protects the third motor, prevents steel balls from hitting the surface of the third motor, and ensures the service life of the third motor.

[0013] Preferably, a fixing frame is fixedly connected to the top of the support plate, and the surface of the first motor is fixedly connected to the inner wall of the fixing frame.

[0014] Preferably, a placement frame is fixedly connected to the bottom of the protection frame, and the surface of the second motor is fixedly connected to the inner wall of the placement frame. The placement frame protects the second motor, prevents steel balls from splashing onto the surface of the second motor, and ensures the service life of the second motor.

[0015] The beneficial effects of the utility model are:

[0016] 1. The use of gears, racks, clamping blocks and the third motor realizes the clamping and flipping of the structural parts, thereby ensuring that the shot blasting equipment can perform all-round shot blasting on the structural parts and improving the shot blasting effect of the shot blasting equipment on the structural parts. The use of electric push rods and protective frames realizes the upward adjustment of the structural parts, ensuring that the structural parts will not touch the placement table during flipping, and the adjustment of the position of the structural parts is simple;

[0017] 2.

DETAILED DESCRIPTION

[0023] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0024] When implementing: Figure 1-4As shown, a structural part pre-treatment shot blasting equipment includes: a processing box 1, the top of the processing box 1 is connected to a shot blasting machine 2, the inner wall of the processing box 1 is fixedly connected to a support plate 3, and the top of the support plate 3 is provided with an adjusting mechanism 4; wherein, the adjusting mechanism 4 includes a first motor 41 arranged on the top of the support plate 3, the output shaft of the first motor 41 is fixedly connected to a placement table 42, a gear 43 is provided on the top of the support plate 3, the surface of the gear 43 is meshedly connected with two racks 44, the surface of the rack 44 is fixedly connected with a driven frame 45, the inner wall of the driven frame 45 is rotatably connected with a clamping block 46, and the bottom end of the placement table 42 is provided with a driving assembly 47.

[0025] A bearing pad is fixedly connected to the top of the placement platform 42 . The bearing pad is a rubber component. The bearing pad increases the friction between the structural component and the placement platform 42 , ensuring the stability of the structural component placed on the placement platform 42 .

[0026] Shot blasting equipment is usually composed of a shot blasting room, a steel column, a shot blasting system, a dust removal system, a conveying system, and a control system. The shot blasting process of structural parts by shot blasting equipment is an existing conventional technology, so it will not be described in detail here.

[0027] When it is necessary to perform shot blasting on the structural parts, the structural parts are placed in the processing box 1, and the first motor 41 is started. The output shaft of the first motor 41 rotates to drive the placement table 42 and the structural parts to rotate smoothly. The shot blasting machine 2 transports the steel balls in the processing box 1 and throws them on the surface of the structural parts for shot blasting. After a period of shot blasting, the protective frame 471, the driven frame 45 and the clamping block 46 are driven to move to the appropriate position, and the driving gear 43 rotates. The rotation of the gear 43 drives the two racks 44 to approach each other. The rack 44 moves through the driven frame 45 to drive the clamping block 46 to move, so that the two clamping blocks 46 clamp the structural parts. At this time, the clamping block 46 and the structural parts are driven to move to the appropriate position, and the clamping block 46 and the structural parts are driven to flip to the surface that needs shot blasting, and the flipped structural parts are placed on the placement table 42. At this time, the shot blasting machine 2 starts to shot blast the flipped structural parts.

[0028] like Figure 2 and Figure 4 As shown, the drive assembly 47 includes an electric push rod 472 fixedly connected to the bottom end of the placement table 42, the telescopic end of the electric push rod 472 is fixedly connected to the protective frame 471, both ends of the gear 43 are rotatably connected to the inner wall of the protective frame 471, the surface of the rack 44 is slidably connected to the inner wall of the protective frame 471, the bottom end of the gear 43 is fixedly connected to the second motor 474, and one end of the clamping block 46 is fixedly connected to the third motor 473.

[0029] The first motor 41 , the second motor 474 and the third motor 473 are all servo motors. A servo motor is a motor that can precisely control position, speed and acceleration, and is typically used in applications requiring high-performance motion control and precise positioning.

[0030] Start the electric push rod 472, and the telescopic end of the electric push rod 472 moves up to drive the protective frame 471, the driven frame 45 and the clamping block 46 to move to the appropriate position, then start the second motor 474, and the output shaft of the second motor 474 rotates to drive the gear 43 to rotate, and the gear 43 rotates through the two racks 44 and the driven frame 45 to drive the two clamping blocks 46 to clamp the structural member. At this time, the telescopic end of the electric push rod 472 moves up to drive the structural member to move to the appropriate position, and start the two third motors 473. The output shafts of the two third motors 473 rotate at the same time to drive the clamping block 46 and the structural member to flip to the surface that needs shot blasting, and place the flipped structural member on the placement table 42. At this time, the shot blasting machine 2 performs shot blasting on the flipped structural member.

[0031] like Figure 2 As shown, the tops of the placement table 42 and the support plate 3 are each provided with a through hole 4710. The thrown steel balls pass through the through hole 4710 and fall into the inner wall of the treatment box 1. The inner wall of the treatment box 1 filters the thrown steel balls and then passes through the shot blasting machine 2 and is thrown onto the structural member again, preventing the thrown steel balls from being retained on the placement table 42 and the support plate 3.

[0032] like Figure 4 As shown, the bottom end of the placement table 42 is fixedly connected to a driven block 475, the inner wall of the driven block 475 is rollingly connected to a ball 476, the surface of the ball 476 is rollingly connected to the top of the support plate 3, the surface of the driven frame 45 is slidingly connected to the inner wall of the driven block 475, and both sides of the driven block 475 are fixedly connected to a scraper 478, and the bottom of the scraper 478 contacts the top of the support plate 3.

[0033] The rotation of the placement table 42 drives the driven block 475, the ball 476 and the scraper 478 to move. The moving scraper 478 scrapes the steel balls retained on the support plate 3, so that the ball 476 can roll smoothly on the support plate 3, ensuring that the placement table 42 remains stable during rotation on the support plate 3.

[0034] like Figure 3-4As shown, a blocking frame 477 is fixedly connected to the surface of the driven frame 45, a surface of the third motor 473 is fixedly connected to the inner wall of the blocking frame 477, a fixing frame 479 is fixedly connected to the top of the support plate 3, a surface of the first motor 41 is fixedly connected to the inner wall of the fixing frame 479, a placement frame 4711 is fixedly connected to the bottom of the protection frame 471, and a surface of the second motor 474 is fixedly connected to the inner wall of the placement frame 4711. The blocking frame 477 is used to prevent steel balls from being thrown and hitting the third motor 473, the fixing frame 479 is used to prevent steel balls from splashing onto the first motor 41, and the placement frame 4711 is used to prevent steel balls from splashing onto the second motor 474.

[0035] When the present invention is in use, the structural part is placed in the processing box 1, and the first motor 41 is started. The output shaft of the first motor 41 rotates to drive the placement table 42 and the structural part to rotate smoothly, and the shot blasting machine 2 transports the steel balls in the processing box 1 and throws them onto the surface of the structural part for shot blasting. After a period of shot blasting, the electric push rod 472 is started, and the telescopic end of the electric push rod 472 moves up through the protective frame 471 and the driven frame 45 to drive the clamping block 46 to move to the corresponding position, and the second motor 474 is started. The output shaft of the second motor 474 rotates through the gear 43, the rack 44 and the driven frame 45 to drive the two clamping blocks 46 to clamp the structural part. At this time, the telescopic end of the electric push rod 472 moves up to drive the structural part to move to the appropriate position, and the two third motors 473 are started. The output shafts of the two third motors 473 rotate at the same time to drive the clamping block 46 and the structural part to flip to the surface that needs shot blasting, and place the flipped structural part on the placement table 42. At this time, the shot blasting machine 2 performs shot blasting on the flipped structural part.

[0036] It should be noted that the shot blasting machine 2, the first motor 41, the second motor 474, the third motor 473 and the electric push rod 472 in the above description are all devices with relatively mature applications in existing technologies. The specific models can be selected according to actual needs. At the same time, the shot blasting machine 2, the first motor 41, the second motor 474, the third motor 473 and the electric push rod 472 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0037] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
