Description

Technical Field

[0001] The utility model relates to a tooling for a hook-through shot blasting cleaning machine. Background Art

[0002] In the traditional shot blasting process, a common shot blasting machine used is a hook-through type shot blasting machine. Specifically, a catenary conveyor chain is provided above the shot blasting chamber, and a set of hooks are hung on the catenary conveyor chain. The hanger of the hook is used to introduce the conveying power into the shot blasting chamber, that is, the device for conveying the workpiece is placed outside the shot blasting chamber to prevent the harsh working environment in the shot blasting chamber from affecting the catenary conveyor chain. Accordingly, a gap is opened at the top of the shot blasting chamber for the intervention of the hanger. During shot blasting, the workpiece is suspended by the hook and driven by the catenary conveyor chain, and passes through the shot blasting chamber in a predetermined direction. Therefore, this type of shot blasting machine is generally called a hook-through type shot blasting machine.

[0003] Hook-through shot blasting machines are suitable for a wide range of workpieces, including a wide range of geometric dimensions. For example, if a hook-through shot blasting machine can handle a maximum workpiece size of 2000×2000×2000 (unit: mm), meaning the hook can suspend such a workpiece, the number of hooks suitable for this application is relatively small. However, if the same hook-through shot blasting machine is used to clean a workpiece with dimensions of, for example, 100×100×100 (unit: mm), it would result in significant waste and low overall cleaning efficiency. For ease of explanation, workpieces of varying sizes are referred to as large and small workpieces, respectively.

[0004] Large workpieces can often be directly suspended from a hook, allowing for convenient cleaning on a hook-type shot blasting machine. However, due to size and weight limitations, small workpieces often require specialized tooling designed specifically for cleaning. Simply hanging them from a hook results in waste and relatively low cleaning efficiency, as previously mentioned. In contrast, using tooling specifically for small workpieces requires frequent tooling changes for different workpiece sizes, resulting in low overall cleaning efficiency.

[0005] Typically, in some implementations, a tooling device with several small hooks can be directly hung under a boom suitable for small workpieces. Although this tooling device can be used to shot blast small workpieces in batches, it suffers from poor stability when hung on the hooks and requires frequent tooling changes, resulting in relatively low overall efficiency. Utility Model Content

[0006] The purpose of the utility model is to provide a tool for a hook-through shot blasting cleaning machine with a relatively wide range of applications.

[0019] A pair of ear plates are provided on the side of the main beam to match each wing beam. The part of the wing beam with the hinge shaft hole is located between the two ear plates for passing the hinge shaft. One of the two ear plates constitutes the upper ear plate and the other constitutes the lower ear plate.

[0020] Optionally, the hinge shaft has two half-shaft bodies, each half-shaft body having a head portion larger than the diameter of the shaft body;

[0021] One of the half-axles passes through the upper pin hole on the upper ear plate from top to bottom and matches with the hinge shaft hole; the other half-axle passes through the lower pin hole on the lower ear plate from bottom to top and matches with the hinge shaft hole.

[0039] Generally speaking, for a catenary conveyor chain, a group of hangers are often evenly suspended on the chain ring. The catenary conveyor chain is located outside the shot blasting room. The lower end of the hanger has a hook, and the hook is located in the shot blasting room. The hanger is used to connect the hook in the shot blasting room with the conveyor chain outside the shot blasting room.

[0040] Correspondingly, a slit is opened at the top of the shot blasting chamber, which is located directly below one of the chain edges of the chain ring. The hanger and the slit are usually adapted to be equipped with a dynamic sealing structure, which allows the hanger to move along the slit in a dynamic and sealed manner, thereby carrying the suspended workpiece through the shot blasting chamber. It can be seen from this that the arrangement direction of the hanger is arranged in the direction of passage of the shot blasting chamber simply with respect to the chain edge located directly above the shot blasting chamber. According to the basic reference system determined by the mechanical field regarding operation, it is known that the forward direction is generally determined by the direction of travel, and the reverse direction is the backward direction. Based on the front and back, the left and right can also be determined.

[0041] In addition, front and back are also called longitudinal, length or head-to-tail direction, while left and right are called transverse or width.

[0042] As previously explained, the terms "large" and "small" are used to categorize workpieces, allowing them to be hung in different locations. This should be clear from the examples of this utility model. However, this is not discussed in detail in the examples of this utility model, as different companies may have different requirements, and this can be determined without inventive effort. In the examples of this utility model, "large" and "small" are used to indicate categorization; in other words, they are divided into two categories, and the use of "large" and "small" to designate them is a naming convention.

[0043] In an embodiment of the present invention, a tooling for a hook-through shot blasting machine is provided, which includes a main beam and a wing beam, wherein the main beam is used as a direct mounting carrier for the workpiece, and the wing beam is equivalent to a mounting carrier for the workpiece indirectly hung on the main beam. It can be seen that the carrying capacity of the main beam is greater than that of the wing beam, so that technical personnel in this field can choose the mounting bases for "large workpieces" and "small workpieces" accordingly. Specifically, large workpieces are generally directly mounted on the main beam as the mounting base, and small workpieces are generally directly mounted on the wing beam as the mounting base. After all, the main beam has a mounting part that does not overlap with the wing beam, so small workpieces can also use the main beam as the mounting base at the same time.

[0044] The main beam is a straight beam and is mounted along the chain. There are usually two hanging points, but there can be more, depending on the preset length of the straight beam and the density of the hangers on the chain. Figure 1 In the illustrated structure, the I-beam 1 used as the main beam has two hangers 4 mounted on the conveyor chain, one at each end of the I-beam 1 .

[0045] The structure used to mount the I-beam 1 on the conveyor chain is called the first connecting structure, which is suitable for the hook provided at the lower end of the boom. The first connecting structure should be suitable for the hook, such as a lifting ring or other structure suitable for the hook.

[0046] exist Figure 5 In the illustrated structure, the hanger 4 is a plate-like structure, with the main body being the first plate 41 shown in the figure. The normal to the surface of the first plate 41 is in the direction of extension of the I-beam 1. The hook hole 43 shown in the figure is oriented with its axis in the direction of extension of the I-beam 1 and is located at the upper end of the hanger 4. Alternatively, a steel ring may be welded to the upper end of the first plate 41, forming a lifting ring suitable for hooking.

[0047] Furthermore, in Figure 1 and Figure 4 In the illustrated structure, a set of workpiece hangers 3 are provided on the lower side of the I-beam 1 used as the main beam. The workpiece hangers 3 are fixed on the I-beam 1. Figure 5 and Figure 6 In the installed state, the workpiece hanger 3 and the hanging member 4 are equivalent to being flipped 180 degrees, and the shapes are the same, which will not be described here as an example.

[0048] Since, for example, the workpiece hanger 3 and the hanger 4 both provide a hole-type connection structure, in some implementations, the aforementioned hanging ring may be used, and the hanging ring may be directly welded to, for example, the flange plate of the I-beam 1 .

[0049] Regarding the general concept of I-beams, the two parallel plates on an I-beam are generally called flange plates, also known as side plates; the plate perpendicularly connecting the two flange plates is called the web plate, also known as the waist plate. Accordingly, the workpiece hangers 3 and 4 are primarily mounted on the corresponding flange plates.

[0050] See also Figures 4 to 6 The workpiece hanger 3 and the hanging member 4 are both installed on the I-beam 1 as accessory plates, and the connection between the workpiece hanger 3 and the hanging member 4 and the I-beam 1 can be a detachable connection. Figure 5 As mentioned above, the two have the same structure and can use the same accessories for spare parts, but they are different in the installation method. Therefore, only the hanger 4 is described in detail below, and the workpiece hanger 3 can be referred to and applied.

[0051] Figure 5 The middle hanging piece 4 is a bilaterally symmetrical, roughly polygonal structure with a through slot in the lower part, which is a T-slot 42 as a whole. The shape of the T-slot 42 is made with reference to the shape of the upper and middle part of the I-beam 1, and it appears as a similar figure in the cross section. The T-slot 42 can be slightly larger to facilitate the insertion of the I-beam 1. The slightly larger size mainly reflects the fitting clearance between the two sides of the T-slot 42 and the I-beam 1, and the fitting clearance can be controlled within 1~5mm.

[0052] The T-slot 42 can also be made in a transition fit manner. Simply relying on the fit between the T-slot 42 and the upper flange plate and part of the web of the I-beam 1 can achieve a better combination, and no other connections are required to facilitate, for example, the position adjustment of the hanger 4 on the I-beam 1.

[0053] In some embodiments, after the hanger 4 is adjusted into position, welding can be used to fix the position of the hanger 4 to prevent it from loosening.

[0054] The welding can also be performed to lock the position of the hanger 4, for example, by using a stop pin.

[0055] In addition, for example, a mounting plate can be welded on the upper side of the T-slot 42, and screw holes can be opened on the mounting plate, and then screws or set screws can be used to lock the hanger 4 to the upper flange plate of the I-beam 1.

[0056] As can be seen from the description of the hanger 4 and the workpiece hanger 3, the upper side of the main beam has a primary connection structure for hanging from the hook, while the lower side of the main beam provides a secondary connection structure for mounting the workpiece. The main beam is the base of the tooling and the primary load-bearing component, making it suitable for mounting relatively heavy workpieces.

[0057] Furthermore, regarding the wing spar, Figure 3The hanging rod 8 shown in the figure uses the main beam as the installation base. In other words, it is equivalent to mounting the workpiece on the main beam with the help of the wing beam. Compared with the main beam, this connection method of the wing beam reduces the ability to mount the workpiece. Therefore, it is suitable for mounting workpieces with relatively small weight.

[0058] The presence of the wing spars expands the range and number of workpieces that can be mounted on the main beam. This expansion, while within the main beam's weight-carrying capacity, increases the number of workpieces while necessarily reducing the weight of each workpiece. This is particularly suited for smaller workpieces. This also shows that when shot blasting large workpieces, the main beam bracket is the primary mounting method. When shot blasting small workpieces, the wing spars primarily serve as the mounting base, although the use of workpiece hangers 3 for mounting small workpieces is not excluded. This process eliminates the need for tooling changes, thereby improving overall shot blasting efficiency.

[0059] From the perspective of expanding the mounting range, the wing spars are arranged on both sides of the main beam along the direction of the main beam. Figure 3 In the illustrated structure, four hanging rods 8 serving as wing beams are provided on both sides of the I-beam 1. The hanging rods 8 on both sides are installed on the I-beam 1 in a symmetrical arrangement. Each hanging rod 8 is provided with 8 second workpiece hanging holes 81. Four groups of eight hanging rods 8 can provide fifty-six second workpiece hanging holes 81. While expanding the workpiece mounting range, it is limited by the total load-bearing capacity of the main beam and the load-bearing capacity of the wing beam unit. When using the wing beam for workpiece mounting, the weight of the workpiece unit will inevitably be reduced, making it suitable for mounting small workpieces.

[0060] For example, the second workpiece hanging hole 31 is recorded as the third connecting structure. As mentioned above, the hanging hole is only a structure suitable for hanging the workpiece. In some embodiments, for example, a ring-like structure, a hook-like structure, etc. can be used for hanging the workpiece.

[0061] To reduce interference, the wing spar is connected to the main beam via a vertical hinge, allowing the wing spar to be extended to a first position at a first predetermined angle relative to the main beam, or retracted to a second position at a second predetermined angle relative to the main beam. The first position allows the wing spar to be used for mounting workpieces, while the second position, which can be understood as primarily using the main beam for mounting workpieces, allows the wing spar to be retracted to reduce interference when mounting large workpieces.

[0062] Preferably, if Figure 3 The figure shows the structure of the spar hanger 8 in its first state. The angle between the hanger 8 and the I-beam 1 is 90°, which reduces the interaction between the workpieces. The corresponding second predetermined angle is 0°, which makes the tooling structure the most compact.

[0063] Figure 3The diagram shows a relatively ideal state. If the spar is relatively long, it is difficult to achieve the second predetermined angle of 0° when the spar is in the second state, but it is still in the ultimate folding state. In addition, as a folding consideration, it is relatively appropriate for the second predetermined angle to be no greater than 15°.

[0064] Since vibration or impact of shot materials will be generated during the shot blasting process, in order to ensure the position stability of the wing spar during the shot blasting process when the wing spar is in the second state, an interlocking structure is provided between the wing spar and the main beam so that the wing spar can be locked to the main beam when the wing spar is in the second state.

[0065] When the spar is in its reset state, or second state, it is interlocked with the main beam using the interlocking structure, ensuring a relatively stable second state. One interlocking structure, referred to as the first interlocking structure, comprises a pin hole in the spar and a corresponding latch in the main beam. When the spar is in the second state, the latch is inserted into the pin hole to achieve locking. The pin hole is parallel to the spar's hinge axis.

[0066] As another form of latch, adapted for the second interlocking structure, a first receptacle is provided on the spar and a corresponding second receptacle is provided on the main beam, allowing the latch to be used to lock the spar after it is stowed. When the spar is in the second position, the first receptacle aligns with the second receptacle, allowing the latch to be used to lock the spar.

[0067] The locking efficiency of the latch is relatively high, and the locking reliability is also good. Accordingly, the latch should be a latch that is locked vertically. This type of latch generally has a head or a bend, and the locking is fast and accurate.

[0068] A third interlocking structure is provided, in which a hook with a retaining plate is provided on the wing spar, and a corresponding hook ring is provided on the main beam. During use, the wing spar is directly pushed toward the main beam, and the retaining plate hits the hook ring and is squeezed open until the hook ring releases the push on the retaining plate, causing it to return to its original position, thus forming a lock. For an unfolding type, manually press the retaining plate to swing the spar out. Since the hook with the retaining plate is a common form in the mechanical field, it will not be described in detail here.

[0069] Regarding the fourth interlocking structure, the spar is equipped with a necked portion to be clamped, and the main beam is equipped with a double spring with an inlet and a clamping cavity for clamping. This clamping structure mainly relies on the clamping of the spring to achieve a certain locking force. The force required to swing the spar out only needs to exceed this locking force.

[0070] exist Figure 1 The illustrated structure includes a locking screw 2 which acts as a latch, except that the locking screw 2 and the upper flange plate of the I-beam 1 can be threadedly engaged, which results in relatively good reliability.

[0071] Finally, see the hinged connection between the wing spar and the main beam. Figure 2 In the figure, a pair of hinge bolts 5 are used to construct the hinge, and one of the two hinge bolts 5 is inserted into the corresponding hinge hole from the bottom side, and the other is inserted into the corresponding hinge hole from the top side. At this time, the locking method of the hinge bolt 5 can be reflected in that there is no threaded connection between the hinge bolt and the wing beam, but the hinge body is provided by a part of the screw or the light rod. The hinge bolt 5 can be fixedly connected with the ear plate 7 shown in the figure. This structure has a relatively good anti-loosening effect.

[0072] Also in Figure 2 In the illustrated structure, a pair of ear plates 7 are provided on the side of the main beam, adapted to each wing beam. The part of the wing beam with the hinge shaft hole is located between the two ear plates for passing the hinge shaft; one of the two ear plates 7 constitutes the upper ear plate and the other constitutes the lower ear plate.

[0073] In some embodiments, only one ear plate 7 may be provided, which is located below the upper flange plate of the I-beam 1 , and the space left between the ear plate and the upper flange plate is used for the insertion and installation of the wing spar.

[0074] As mentioned above, the two hinge bolts 5 form two half-axles, that is, the hinge used to hinge the wing spar and the main beam is divided into two parts. The two half-axles are fixed separately to reduce the influence of the wing spar friction on, for example, the threaded pair.

[0075] The half-axle body has a head that is larger than the diameter of the axle body, constituting a constraint, e.g. Figure 2 The hinge shaft bolt 5 shown in the figure has a bolt head larger than the corresponding hinge shaft hole, thereby constraining it.

[0076] For the configuration using two half-axles, one of the half-axles passes through the upper pin hole on the upper ear plate from top to bottom and cooperates with the hinge shaft hole; the other half-axle passes through the lower pin hole on the lower ear plate from bottom to top and cooperates with the hinge shaft hole.

[0077] Figure 2 A method of fixing the half-axle body is also shown in the figure. The hinge bolt 5 shown in the figure is tightened with a nut after passing through the hole opened in the flange plate.

[0078] In addition, in order to improve the overall strength, a reinforcement plate 9 is provided at the portion of the main beam used for connecting with the wing beam.
