Description

Technical Field

[0001] This utility model belongs to the field of fitness strength rack processing technology, and in particular relates to a processing device for a steel frame of a fitness strength rack. Background Technology

[0002] A weightlifting rack is a type of fitness support structure composed of steel columns of varying lengths. As an auxiliary support, it allows users to support and place barbells on the rack while lifting them.

[0003] The production process of a fitness weightlifting rack requires numerous processing operations, such as drilling multiple holes in the steel structure column support (the holes are used to install the support rods for the barbell) and welding mounting components, such as connecting ear plates, to the steel structure column.

[0004] During the production process, the workshop can usually only process one piece of steel at a time. The processing method is to place the steel on a pad or workbench and then perform drilling and welding operations.

[0005] During processing, such as welding, it is often necessary to adjust the position of the steel to facilitate welding the connectors onto different surfaces of the steel. However, due to the large length and weight of the steel, flipping it over is extremely laborious. Furthermore, since the steel cannot be kept flat after the connectors are welded to one side, multiple operators are needed to assist in supporting the welding process after flipping the steel over to weld the other side.

[0006] Therefore, the real reason for the above-mentioned technical defects is that the steel material often needs to be constantly adjusted in the process of handling it, and the steel material with a slightly larger length and weight is difficult to adjust in terms of its posture.

[0007] Secondly, the processing of steel often includes processes such as drilling. Therefore, a single piece of steel often involves multiple processing methods (including welding, drilling, polishing, etc.). As a result, if the steel cannot be rotated flexibly, the processing becomes relatively difficult. Utility Model Content

[0008] Based on the above background, the purpose of this utility model is to provide a steel frame processing device for fitness strength racks.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A steel frame processing device for a fitness strength rack includes a single-axis positioner, with a long tooling shaft fixedly installed between the power output ends of the single-axis positioner; and a plurality of support mechanisms for supporting steel materials are assembled and connected between the long tooling shafts.

[0011] The support mechanism includes a bracket mounted on a long tooling shaft, and several V-shaped locking brackets are installed on the outside of the bracket.

[0012] The V-shaped locking frame has sliding grooves on both sides, and an inner groove screw is fixedly installed in the sliding groove. A locking plate for locking the steel material frame is installed between the inner groove screws.

[0013] The spacing between the support mechanisms can be adjusted.

[0014] The long tooling shaft is equipped with several perforated support structures, which provide support for the steel material rack during the perforation process.

[0015] Preferably, the longitudinal cross-sectional shape of the bracket is annular;

[0016] An inner diameter plate is fixedly connected inside the bracket, and a long sliding opening is provided on the long tooling shaft, through which the inner diameter plate is slidably connected.

[0017] Preferably, end brackets are fixedly connected to both ends of the long tooling shaft;

[0018] The end bracket is fixedly installed on the power input end of the single-axis positioner;

[0019] A long adjusting rail is fixedly connected between the two sides of the end bracket, and the inner diameter plate is slidably connected to the long adjusting rail.

[0020] Preferably, the long adjusting rail is threaded with several pairs of adjusting nuts respectively positioned on both sides of the inner diameter plate.

[0021] Preferably, the two ends of the locking plate are slidably connected to the inner groove screw, and the inner groove screw is threaded with a pressing nut for pressing down the locking plate.

[0022] Preferably, the V-shaped locking bracket is fixedly installed on the outer side wall of the bracket by a mounting structure;

[0023] The installation structure includes a locking rod fixedly connected to the bottom of the V-shaped locking frame, and a locking seat that engages with the locking rod is fixedly connected to the outer wall of the bracket. A through screw is installed on the locking seat, and the through screw passes through the locking rod and then through the locking seat.

[0024] A nut is threaded onto the through screw.

[0025] Preferably, the hole-opening support structure includes a sliding sleeve slidably connected to a long tooling shaft, a top screw fixedly connected to the top of the sliding sleeve, and a support screw threadedly connected to the top screw. During the hole-opening process, the support screw is adjusted to support the bottom of the hole-opening position.

[0026] Preferably, the sliding sleeve is threaded with a locking bolt, which is locked onto the long tooling shaft.

[0027] Preferably, a knob is fixedly connected to the outer end of the locking bolt.

[0028] This utility model has the following beneficial effects:

[0029] 1. During operation, the operator can rotate the entire device while welding steel. Because multiple steel pieces are locked and rotated, the device allows for easy switching to the next piece after processing one. The top and sides of the steel pieces can be easily processed during the welding process. Since the steel pieces are suspended and locked, and their position can be adjusted by rotation, it is convenient to weld connecting parts to the top and sides of the steel pieces (in actual operation, when the upper steel piece is rotated to the lower position, the bottom surface of the steel piece is exposed upwards, allowing for welding operations on the bottom surface). This structure allows for convenient adjustment of the steel piece's position during the welding process.

[0030] The above structure greatly reduces the difficulty of welding operations, and at the same time, it enables the simultaneous loading and clamping of multiple steel materials for processing, which greatly improves processing efficiency.

[0031] 2. Several hole-opening support structures are installed on the long tooling shaft. During the hole-opening process of the steel rack, the bottom of the steel material at the hole-opening position is supported by the hole-opening support structures to facilitate hole opening and support the steel material. When the drill bit enters the steel material during the hole-opening process, the bottom position of the steel material is supported, thus increasing the stability of the hole opening.

[0043] Example 1

[0044] like Figure 1-6 As shown, a steel frame processing device for a fitness strength rack includes a single-axis positioner 1, which is a conventional single-axis positioner 1 disclosed in the prior art. That is, similar to existing single-axis positioners 1, the single-axis positioner 1 includes a pair of main units. One main unit houses a motor and drive shaft structure, and the other main unit houses a driven shaft. According to existing methods, a long tooling shaft 3 is fixedly installed between the power output ends of the single-axis positioner 1. Specifically, the two ends of the long tooling shaft 3 are fixedly connected to end brackets 31; the end brackets 31 are fixedly installed on the power input end of the single-axis positioner 1 (i.e., one end bracket 31 is installed on the drive shaft of one main unit, and the other end bracket 31 is installed on the driven shaft of the other main unit).

[0045] Those skilled in the art can learn about the specific structure and working principle of the single-axis positioner 1 disclosed in this utility model, as well as the specific structure and working principle of the long tooling shaft 3 being driven to rotate by the single-axis positioner 1, by consulting technical manuals and dictionaries.

[0046] Several support mechanisms 2 for supporting steel materials 5 are assembled and connected between the aforementioned long tooling shafts 3. Specifically, three support mechanisms 2 are arranged, distributed at the front and rear ends and the middle position of the long tooling shafts 3.

[0047] The specific structure of support mechanism 2 is as follows:

[0048] The support mechanism 2 includes a bracket 21 (the longitudinal cross-sectional shape of the bracket 21 is annular) mounted on the long tooling shaft 3. The bracket 21 is mounted on the long tooling shaft 3 in a sliding connection manner. Specifically, the sliding connection method is as follows: an inner diameter plate 22 is fixedly connected inside the bracket 21, and a long sliding opening is opened on the long tooling shaft 3, in which the inner diameter plate 22 is slidably connected.

[0049] Meanwhile, a long adjusting rail 25 is fixedly connected between the two sides of the end bracket 31, and the inner diameter plate 22 is slidably connected to the long adjusting rail 25. Several pairs of adjusting nuts, respectively positioned on both sides of the inner diameter plate 22, are threaded onto the long adjusting rail 25.

[0050] During operation, the position of the bracket 21 can be adjusted through the above structure, so as to facilitate the support and positioning of a certain length of steel material 5 segments through the bracket 21.

[0051] The adjustment method is as follows: after loosening the adjusting nut, slide the bracket 21. During the sliding adjustment process, the bracket 21 slides on the long tooling shaft 3.

[0052] Several V-shaped locking frames 23 are installed on the outside of the aforementioned bracket 21. The V-shaped locking frames 23 are arranged in a circumferential array. During operation, multiple steel materials 5 are placed along the same straight line position of the V-shaped locking frames 23 (the relative distance between the brackets 21 is adjusted in advance before placing the materials), and then the operator locks the steel materials 5.

[0053] Specifically, the V-shaped locking bracket 23 has sliding grooves on both sides, and an inner groove screw 26 is fixedly installed in the sliding groove. A locking plate 24 for locking the steel material 5 frame is installed between the inner groove screws 26. Specifically, the two ends of the locking plate 24 are slidably connected to the inner groove screws 26, and the inner groove screws 26 are threaded with a pressing nut 261 that presses down on the locking plate 24.

[0054] The locking method is as follows:

[0055] The operator slides down the locking plate 24 until it presses against the steel material 5, and then tightens the lower nut 261. This method locks the steel material 5 in place.

[0056] During operation, the operator can rotate the entire device while welding the steel material 5. Because multiple steel materials 5 are locked and flipped, the device can be switched to process the next steel material 5 after processing one. During processing, the top surface and sides of the steel material 5 can be easily processed. Furthermore, because the steel material 5 is suspended and locked, and its position can be adjusted by flipping, it is convenient to weld connecting parts to the top surface and sides of the steel material 5 (in actual operation, when the upper position of the steel material 5 is flipped to the lower position, the bottom surface of the steel material 5 is exposed upwards, allowing for welding operations on the bottom surface of the steel material 5).

[0057] The above structure enables convenient adjustment of the steel material's position during the welding process.

[0058] The above structure also facilitates other processing of the steel material 5, such as drilling. Since the posture of the steel material 5 can be easily adjusted, the difficulty of drilling is greatly reduced.

[0059] Example 2

[0060] like Figure 1-6 As shown, in this embodiment, based on the structure of embodiment 1, the V-shaped locking bracket 23 is fixedly installed on the outer wall of the bracket 21 by the mounting structure.

[0061] The installation structure includes a locking rod fixedly connected to the bottom of the V-shaped locking bracket 23. A locking seat 211 for engaging the locking rod is fixedly connected to the outer wall of the bracket 21. A through screw is installed on the locking seat 211, which passes through the locking rod and then through the locking seat 211 (through holes are opened on the locking seat 211 and the locking rod). A nut is threaded onto the through screw.

[0062] The above structure allows for easy detachment and installation of the V-shaped locking bracket 23.

[0063] Example 3

[0064] like Figure 1-6 As shown, in this embodiment, based on the structure of embodiment 2, several opening support structures 4 are installed on the long tooling shaft 3. During the opening process of the steel material 5, the bottom of the opening position of the steel material 5 is supported by the opening support structures 4, so as to facilitate the opening while supporting the steel material 5. When the drill bit drills into the steel material 5 during the opening process, the bottom position of the steel material 5 is supported, thus increasing the stability of the opening.

[0065] Specifically, the hole-opening support structure 4 includes a sliding sleeve 41 (which can both slide and rotate) slidably connected to the long tooling shaft 3. A top screw 42 is fixedly connected to the top of the sliding sleeve 41, and a support screw tube 43 is threadedly connected to the top screw 42. During the hole-opening process, the support screw tube 43 is adjusted to support the bottom of the hole-opening position. Specifically, during the hole-opening process, the top screw 42 is turned until its top supports the bottom of the steel material 5 (the position of the hole-opening support structure 4 is pre-adjusted, such as by sliding adjustment of the hole-opening position). Then, the operator uses a hole-opening device, such as a hole-opening screwdriver, to open the hole. The advantage of this method is that, during the hole-opening process, because the support screw tube 43 supports the bottom of the hole-opening position, the cavity of the support screw tube 43 provides a buffer cavity for the drill bit after it penetrates the steel material 5.

[0066] The aforementioned sliding sleeve 41 is threaded with a locking bolt 44, which is locked onto the long tooling shaft 3. A knob is fixedly connected to the outer end of the locking bolt. When the position of the sliding sleeve 41 is adjusted to the opening position, turning the knob causes the inner end of the locking bolt to press against the long tooling shaft 3, thereby positioning the sliding sleeve 41 (positioning by bolt pressing is a conventional positioning method disclosed in the prior art).

[0067] The above structure supports the opening position of the steel material 5 during the opening process, thereby increasing the stability of the opening.

[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.
