Abstract
Description
Technical Field
[0001] This utility model belongs to the field of fitness frame blank processing technology, and in particular relates to a fitness frame blank processing device. Background Technology
[0002] A weightlifting rack is a support structure made of steel rods through welding, assembly, and other processing methods. During exercise, the user uses the weightlifting rack as an aid to lift the barbell and then lower it onto the rack.
[0003] The structure of a fitness strength frame includes poles of varying lengths, such as the support columns, the tie beams between the upper ends of the support columns, and the support columns at the bottom that support the support columns on the ground. Therefore, the steel rod blanks for the steel structure need to be cut according to the drawings. After being cut into rod blanks of different lengths, they undergo further processing steps such as drilling threaded holes and welding auxiliary connectors to obtain the strength frame. Finally, after finishing processes such as painting, the fitness strength frame is complete.
[0004] During the cutting process, operators need to feed steel structural members of a certain length onto the cutting table, where a cutting machine is installed to cut them. During cutting, operators need to support and stabilize the member, continuously pushing it forward. It is crucial to maintain a straight line while pushing the member to avoid uneven cuts.
[0005] However, in actual operation, due to the placement and support of the rod on the material platform during the pushing process, the friction between the rod and the platform results in numerous scratches on the bottom of the rod, requiring subsequent polishing. Secondly, because the rod is made of steel structure material, its length is relatively large at the beginning of the cutting stage, resulting in greater pushing resistance and a higher degree of frictional damage.
[0006] Meanwhile, during the cutting process, it is often necessary to bevel the cut edge of the rod (this bevel cut facilitates the alignment and welding of a pair of rods). Therefore, adjusting the rod's posture is quite difficult for the operator. After adjustment and cutting, the rod needs to be reset, and the relative posture between the rod and the cutting equipment still needs to be corrected during the reset process, making the cutting operation quite complex and difficult. Utility Model Content
[0007] Based on the above background, the purpose of this utility model is to provide a device for processing fitness strength frame blanks.
[0008] To achieve the above objectives, the present invention adopts the following technical solution:
[0009] A device for processing a fitness rack blank includes a pushing mechanism for pushing the blank. The pushing mechanism includes a guide rail with a guide groove on the guide rail. Several support rollers are rotatably connected to the groove walls on both sides of the guide groove.
[0010] The billet is supported on the support rollers on both sides;
[0011] The pushing mechanism further includes a pusher assembly for pushing the rod blank, the pusher assembly including a sliding pusher arm that pushes at the end position of the rod blank;
[0012] A drive seat is fixedly installed at the bottom of the sliding push arm, and the drive seat is limited to slide at the bottom of the guide groove.
[0013] The drive seat is moved by a lead screw structure;
[0014] The guide rail has an integrally formed material guide chamber at the discharge end, and several cylinders for locking the rod blanks are installed on the material guide chamber.
[0015] Preferably, the support roller is equipped with a rotating shaft that is rotatably connected to the guide rail;
[0016] The support roller has an integrally formed annular partition flange located on the inner side of the support roller; the annular partition flange blocks the outer side of the rod blank.
[0017] Preferably, the bottom of the guide rail is provided with a long sliding opening, and the pusher assembly includes a pair of sliding push arms; the sliding push arms are fixedly connected to the top of the drive seat; the drive seat is limited to slide within the long sliding opening;
[0018] The sliding push arm has a locking slot, which limits the end of the rod blank within the locking slot during the pushing process.
[0019] Preferably, the lead screw structure includes a lead screw threadedly connected to the drive seat, a lead screw motor bracket fixedly installed at the rear end of the guide rail, a lead screw rotating bracket fixedly installed at the front end of the guide rail, and the two ends of the lead screw rotatably connected to the lead screw motor bracket and the lead screw rotating bracket, respectively.
[0020] The lead screw motor is mounted on the lead screw motor bracket.
[0021] Preferably, a rolling structure is fixedly connected to the bottom of the drive seat. The roller structure includes a crossbeam fixedly connected to the bottom of the drive seat, and support rollers are rotatably connected to both ends of the crossbeam.
[0022] Bottom support rails are fixedly connected to both sides of the bottom of the guide rail, and support rollers support the rollers as they roll on the bottom support rails.
[0023] Preferably, a rotating mechanism is assembled and connected to the bottom of the pushing mechanism;
[0024] The rotating mechanism is used to adjust the cutting angle of the rod blank.
[0025] Preferably, the rotating mechanism includes a turntable, and a rotating shaft rotatably connected to the turntable is fixedly installed at the bottom center of the guide rail.
[0026] Preferably, symmetrically arranged arc-shaped rotating seats are fixedly connected to both sides of the bottom of the guide rail;
[0027] The arc-shaped turntable has an arc-shaped sliding opening, and the top two sides of the turntable are respectively fixedly installed with limiting and sliding columns that slide within the arc-shaped sliding opening.
[0028] Preferably, the feed hopper is rectangular in shape;
[0029] A cylinder is installed and connected to each side of the feed hopper, and the piston rod of the cylinder passes through the feed hopper.
[0030] This utility model has the following beneficial effects:
[0031] 1. During operation, when the operator turns on the lead screw motor, the drive seat is pushed under the motor's drive, causing the sliding push arm to contact and push the steel billet at its end. This method automatically moves a relatively long steel billet to the cutting table, adjusting the length of the billet to be pushed as needed. Subsequently, the cutting equipment on the cutting table (specifically, a cutting machine disclosed in the prior art) cuts the steel billet to a specific length. This method achieves automatic cutting of the steel billet, offering high cutting efficiency. Furthermore, the use of lead screw pushing, billet rolling, and confinement within the guide rail effectively solves the problem of friction at the bottom of the billet.
[0032] 2. The design of the feed hopper and cylinder structure ensures that during operation, all cylinders are opened until their piston rods press against the top, bottom, and left and right sides of the billet, maintaining the steel billet's positioning. In this positioned state, the positioning point is close to the cutting point, thus maintaining cutting stability and preventing defects such as billet lifting or shaking that could lead to inaccurate cutting.
[0033] 3. The rotating mechanism facilitates the rotation of the guide rail during the cutting process. After rotation, the steel rod blank placed on the guide rail rotates synchronously. In this way, when a bevel cut is required, rotating the guide rail causes the guide rail and the rod blank on the guide rail to tilt relative to the cutting equipment, thereby achieving the bevel cut.

[0045] Example 1
[0046] like Figure 1-6 As shown, a fitness rack blank processing device includes a pushing mechanism 1 for pushing the blank. The pushing mechanism 1 includes a guide rail 11, on which a guide groove is formed (the length of the guide groove is equal to the length of the guide rail 11). Several support rollers 12 are rotatably connected to the groove walls on both sides of the guide groove. Specifically, according to the existing rotatable connection method, a rotating shaft rotatably connected to the guide rail 11 is installed on the support roller 12; an annular partition flange 121 is integrally formed on the support roller, the annular partition flange 121 is located on the inner side of the support roller; the annular partition flange 121 blocks the outer side of the blank.
[0047] During the operation, the steel structure steel rod blank for processing the frame pole is placed into the guide groove, and the posture of the steel rod blank is adjusted. The outer side of the steel structure steel rod blank abuts against the inner side wall of the annular partition flange 121.
[0048] The aforementioned pushing mechanism 1 also includes a pusher assembly for pushing the rod blank, the pusher assembly including a sliding pusher arm 17 that pushes at the end position of the rod blank.
[0049] During the pushing and cutting process using the pusher assembly, the end of the steel rod blank is pushed by the pusher assembly, and the steel rod blank rolls on the support roller due to the resistance. Therefore, this method makes it easy to push and cut the steel rod blank.
[0050] The aforementioned sliding push arm 17 is slidably connected to the bottom of the guide groove; specifically, the bottom of the guide rail 11 is provided with a long sliding opening, and the push frame assembly includes a pair of sliding push arms 17; a drive seat 172 is fixedly installed at the bottom of the pair of sliding push arms 17 (the upper end of the drive seat 172 is limited to slide within the long sliding opening), and the drive seat 172 is pushed by a screw structure.
[0051] Specifically, the lead screw structure includes a lead screw 142 threadedly connected to a drive seat 172 (the upper end of the drive seat 172 is limited to sliding in a long sliding port, and the lead screw 142 is threadedly connected to the lower end of the drive seat 172).
[0052] Correspondingly, a lead screw motor bracket 141 is fixedly installed at the rear end of the guide rail, and a lead screw rotating bracket is fixedly installed at the front end of the guide rail 11 (the top of the lead screw rotating bracket is lower than the bottom of the steel structure billet, so it does not affect the pushing of the steel structure billet). According to the existing method, the two ends of the lead screw 142 are rotatably connected to the lead screw motor bracket 141 and the lead screw rotating bracket respectively (that is, the rotatable connection method of the lead screw 142 is the same as that of the existing lead screw 142, and lead screw bearings are installed on the lead screw motor bracket 141 and the lead screw rotating bracket).
[0053] Meanwhile, a lead screw motor 14, which drives the lead screw 142 to rotate, is mounted on the lead screw motor bracket 141. During operation, when the operator turns on the lead screw 142 motor, the drive seat 172 is pushed under the drive of the lead screw 142 motor, which in turn slides the push arm 17 to abut against the end position of the steel structure billet. In this manner, a relatively long steel billet is automatically pushed to the cutting table, and the length of the billet being pushed is adjusted according to the required cutting length. Subsequently, the cutting equipment on the cutting table (specifically, a cutting machine disclosed in the prior art) cuts the steel billet to a specific length in the conventional manner.
[0054] During operation, to improve the stability of pushing the steel structure billet, a locking slot 171 is provided on the sliding push arm 17. During the pushing process, the end of the billet is limited within the locking slot 171. The locking slot 171 is used to limit the end of the billet within the locking slot 171 during the pushing process, thereby improving the stability of the pushing.
[0055] Example 2
[0056] like Figure 1-6 As shown, in this embodiment, based on the structure of embodiment 1, in order to maintain a high degree of stability during the movement of the drive seat 172, a rolling structure is fixedly connected to the bottom of the drive seat 172. The rolling structure includes a crossbeam 173 fixedly connected to the bottom of the drive seat 172, and support rollers 1731 are rotatably connected to both ends of the crossbeam 173. Bottom support rails 13 (the bottom support rails 13 are L-shaped) are fixedly connected to both sides of the bottom of the guide rail 1, and the support rollers 1731 support and roll on the bottom support rails 13.
[0057] During the pushing process, the rollers roll on the bottom support rail 13. This method improves the stability of pushing the steel structure billet and also enables the cutting of steel structure billets that are slightly longer and heavier during the operation.
[0058] Example 3
[0059] like Figure 1-6As shown, in this embodiment, based on the structure of embodiment 2, in order to position the steel structure blank near the cutting part during the cutting process and ensure that the steel structure blank does not loosen during the cutting process, a guide hopper 15 is integrally formed at the discharge end (front end) of the guide rail 11. Several cylinders 16 for locking the blank are installed on the guide hopper 15. Specifically, a cylinder 16 is assembled and connected to each side of the guide hopper 15, and the piston rod of the cylinder 16 passes through the guide hopper 15.
[0060] Specifically, the guide bin 15 (which is connected to the guide groove) is rectangular in shape; during the material pushing process, the steel structure billet passes through the guide bin 15 and extends into the cutting table in preparation for cutting.
[0061] Subsequently, the piston rods of all cylinders 16 are opened and pressed along the top, bottom, and left and right sides of the billet, maintaining the steel structure billet in position after pressing. In the positioned state, the positioning point is close to the cutting point, thus maintaining the stability of the cutting and avoiding defects such as billet lifting or shaking that would cause inaccurate cutting during the cutting process.
[0062] Example 3
[0063] like Figure 1-6 As shown, in this embodiment, based on the structure of embodiment 2, a rotating mechanism is assembled and connected to the bottom of the pushing mechanism 1. The rotating mechanism facilitates the rotation of the guide rail 11 during the cutting process, and the steel rod blank placed on the guide rail 11 rotates synchronously after rotation. In this way, when it is necessary to perform oblique cutting, the guide rail 11 is rotated, and the guide rail 11 and the rod blank on the guide rail 11 are tilted relative to the cutting equipment, thereby realizing oblique cutting.
[0064] Specifically, the rotating mechanism is used to adjust the cutting angle of the rod blank. Specifically, the rotating mechanism includes a turntable 19 (in the conventional manner, a base 101 is fixedly connected to the bottom of the turntable 19, and the base 101 is fixedly installed on the worktable), and in the conventional rotating connection method, a rotating shaft that is rotatably connected to the turntable 19 is fixedly installed at the bottom center position of the guide rail 11.
[0065] To increase the stability of the rotating guide rail 11, symmetrically arranged arc-shaped rotating seats 18 (the arc-shaped rotating seats 18 correspond to the shape of the circular turntable 19) are fixedly connected to both sides of the bottom of the guide rail 11. During rotation, the guide rail 11 rotates and the arc-shaped rotating seats 18 rotate relative to the turntable 19.
[0066] Meanwhile, an arc-shaped sliding opening 181 is provided on the arc-shaped rotating base 18, and a limiting fixing column 191 that slides within the arc-shaped sliding opening 181 is fixedly installed on both sides of the top of the turntable 19.
[0067] During the rotation, the guide rail 11 rotates, and the arc-shaped rotating seat 18 rotates accordingly. During the rotation, the limiting fixing post 191 slides relative to the arc-shaped sliding opening 181 in an arc shape.
[0068] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
