Description

Technical Field

[0001] The utility model relates to the technical field of screening tooth processing and detection equipment for toothed roll crushers, and particularly relates to an integrated tooling for screening tooth processing and detection of a toothed roll crusher. Background Art

[0002] A toothed roll crusher, also known as a wolf tooth crusher, is a crushing device widely used in industries such as coal, metallurgy, mining, chemical industry, and building materials, and is particularly suitable for crushing raw coal (including gangue) in large coal mines or coal preparation plants.

[0003] The working principle of a toothed roll crusher mainly lies in the extrusion force and shear force generated by two or four relatively rotating toothed rolls on the material. After the material enters the gap between the toothed rolls, it is subjected to the rotational extrusion and shearing action of the toothed rolls, and thus is broken into the required particle size. Toothed roll crushers are usually used for medium to fine crushing of various materials such as ores and coals. The most important components of a toothed roll crusher are the central shaft and the screening teeth. The fixed installation of the central shaft and the screening teeth is carried out by the keyway on the shaft and the support feet of the screening teeth. The relative installation clearance is only 2 mm. The central shaft is made by precision machining of forgings, while the installation profile of the screening teeth is directly formed by casting, and only the thickness of the screening teeth needs to be processed. Therefore, the profile shape of the screening teeth directly affects the installation. The profile shapes of all screening teeth must be detected and qualified by a special template inspection tool to ensure smooth installation during use. Therefore, it is necessary to provide a professional tooling for the convenient, fast, and accurate detection and processing of the profile shape of the screening teeth.

[0004] The general processing method of existing screening tooth petals is to piece together several petals into a whole circle by welding, and then use a jack to push them apart or directly pry them open after processing, and then polish the welding position, with cumbersome procedures. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art, provide an integrated tooling for screening tooth processing and detection of a toothed roll crusher, and solve the problem of the lack of a professional tooling for the convenient, fast, and accurate detection and processing of the profile shape of the screening teeth.

[0006] The utility model is realized through the following technical solutions:

[0007] An integrated tooling for screening tooth processing and detection of a toothed roll crusher includes a tooling base and a screening tooth locking ring. A cylindrical installation platform is arranged on the tooling base. A plurality of dovetail installation grooves are arranged around the cylindrical installation platform. The dovetail installation grooves are matched and installed with the dovetail installation heads on the screening tooth petals. Two locking ring installation columns are correspondingly arranged on the tooling base. A set of screening tooth locking rings is clamped between two layers of tooth teeth of the screening tooth petals. The two sides of the screening tooth locking ring are correspondingly installed on the locking ring installation columns, so as to fixedly install a plurality of screening tooth petals arranged around the tooling base.

[0008] Furthermore, the tooling base is a circular plate structure, and a plurality of installation slots are arranged around the tooling base.

[0009] Furthermore, a plurality of supporting bosses are arranged on the tooling base around the cylindrical installation table.

[0010] Furthermore, the top end of the supporting boss is a spherical structure. The spherical structure design makes the contact surface between the supporting boss and the support member small, with point contact and three points on one plane, which can effectively compensate for the uneven space of the support member.

[0011] Furthermore, a limiting plate is arranged on the gap between two sieve teeth petals added on the cylindrical installation table.

[0012] Furthermore, the limiting plate is a triangular structure. The bottom edge of the limiting plate is vertically connected to the cylindrical installation table, and the tip of the top angle of the limiting plate is aligned with the middle position of the lower tooth of the sieve tooth petal.

[0013] Furthermore, the sieve tooth locking ring includes two semi-locking rings, and the head and tail of the two semi-locking rings are connected by bolts to form a surrounding structure.

[0014] Furthermore, a locking ear platform for connecting with the locking ring installation post is arranged at the head end of the semi-locking ring, and the sieve tooth locking ring is sleeved on the locking ring installation post through the locking ear platform for installation and fixed connection.

[0015] Furthermore, a set of sieve tooth locking rings is arranged at the bottom of the sieve tooth petal. The set of sieve tooth locking rings arranged at the bottom of the sieve tooth petal and the set of sieve tooth locking rings arranged in the middle of the sieve tooth petal cooperate with each other to fixedly install the sieve tooth petal on the tooling base.

[0016] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0017] 1. The integrated tooling for sieve tooth processing and detection of a toothed roll crusher according to the present invention, by providing a professional tooling for sieve tooth petal detection and processing, by matching and installing the dovetail installation head of the sieve tooth petal in the dovetail installation groove of the cylindrical installation table, and then adding and fixing through the sieve tooth locking ring, solves the problem that the general processing method of the sieve tooth petal is to weld several petals into a whole circle for processing.

[0018] 2. The integrated tooling for sieve tooth processing and detection of a toothed roll crusher according to the present invention, through the arranged limiting plate, there is a gap between adjacent sieve tooth petals during actual installation and use. The function of this limiting plate can effectively prevent the situation that there is no gap between adjacent sieve tooth petals during assembly, that is, if the length of the sieve tooth petal is too long, it will not fit into this tooling. The limiting plate is designed as a triangular protrusion to provide a reference for scribing, leveling the lower row of teeth of the sieve tooth petal to be flush with the triangle, so that the teeth are on the same plane.

[0034] Embodiment 1

[0035] Such as Figure 1-8As shown in the figure, the present utility model relates to an integrated tooling for the processing and detection of the screening teeth of a toothed roll crusher. The most important components of the toothed roll crusher are the toothed roll 15 composed of the screening tooth mounting shaft 14 and the screening tooth flap 5. The fixed installation of the screening tooth mounting shaft 14 and the screening tooth flap 5 is carried out by the keyway on the shaft and the support feet of the screening teeth. The relative installation clearance is only 2 mm. The screening tooth mounting shaft 14 is made by precision machining of forgings, while the installation profile of the screening tooth flap 5 is directly formed by casting, and only the thickness of the screening teeth needs to be processed. The general processing method of the existing screening tooth flaps is to piece together several flaps into a whole circle by welding for processing. After processing, the jack is used to push it open or directly pried open, and then the welding position is polished. The process is cumbersome. The tooling provided by the present utility model for the professional detection and processing of the screening tooth flap 5 is to match and install the dovetail mounting head 6 of the screening tooth flap 5 on the dovetail mounting groove 4 of the cylindrical mounting table 3, and then fix it by installing the screening tooth locking ring 2. The tooling mainly includes a tooling base 1 and a screening tooth locking ring 2. The tooling base 1 is provided with a cylindrical mounting table 3. A plurality of dovetail mounting grooves 4 are arranged around the cylindrical mounting table 3. The dovetail mounting grooves 4 are matched and installed with the dovetail mounting heads 6 on the screening tooth flap 5. The position of the cylindrical mounting table 3 is about 10 mm lower than the thickness of the product (screening tooth flap 5). The purposes of doing this are: 1. To prevent the tooling from being damaged. 2. To directly measure the height dimension directly protruding from the tooling, and then judge whether the total thickness of the product is qualified. The cylindrical mounting table 3 is designed as a whole-circle tooling with grooves according to the screening tooth mounting shaft 14, which can detect whether the screening tooth flap 5 can be smoothly placed. If it can be smoothly placed in the tooling, it means that the product can be smoothly installed on the shaft during use. If it cannot be placed, it means that there are redundant interference parts in the product and it needs to be polished again. In batch production, it can be used as a detection tool to avoid re-detection after processing.

[0036] Two locking ring mounting columns 8 are correspondingly arranged on the tooling base 1. The locking ring mounting columns 8 can be screws for installing the screening tooth locking ring 2. Through nuts or other locking structures, there is a distance between the locking ear platforms 7 on the semi-locking ring 13 and the end faces of the locking ring mounting columns 8. The pre-tightening force is generated by bolts, so as to achieve the purpose of locking the screening tooth flap 5. (The two end faces of the locking block cannot be directly designed to be flush, otherwise the pre-tightening force effect cannot be achieved). A set of screening tooth locking rings 2 are clamped between the two layers of tooth teeth 9 of the screening tooth flap 5. The two sides of the screening tooth locking ring 2 are correspondingly installed on the locking ring mounting columns 8, so as to fixedly install a plurality of screening tooth flaps 5 arranged around the tooling base 1.

[0037] The tooling base 1 is of a circular plate structure, and a plurality of installation slots 10 are arranged around the tooling base 1. The tooling is installed on the vertical lathe workbench through the installation slots 10.

[0038] As Figure 3As shown in the figure, there are multiple supporting bosses 11 on the tooling base 1 around the cylinder adding platform 3. Considering the uneven surface of the sieve tooth lobe 5 before processing, the purpose of setting these bosses is to place the sieve tooth lobe 5 on the multiple supporting bosses 11 for leveling. After leveling, the sieve teeth are tightened by bolts through the locking blocks to prevent the product from loosening during processing. The top of the supporting boss 11 is a spherical structure. The spherical structure design makes the contact surface between the supporting boss 11 and the support member small, with point contact and three points on one plane, which can effectively compensate for the unevenness of the support member space.

[0039] As Figure 1-5 shown, for an integrated tooling for sieve tooth processing and detection of a toothed roll crusher of the present utility model, the operating principle is that the tooling base 1 installs the tooling on the vertical lathe workbench surface through the installation slot 10. A set of sieve tooth locking rings 2 are installed at the bottom of the cylinder adding platform 3, and both sides of the sieve tooth locking ring 2 are correspondingly installed on the locking ring installation posts 8. Multiple cast sieve tooth lobes 5 are installed around the cylinder adding platform 3 by matching the dovetail installation heads 6 of the sieve tooth lobes 5 with the dovetail installation grooves 4 on the cylinder adding platform 3; then a set of sieve tooth locking rings 2 are clamped between the two layers of tooth teeth 9 of the sieve tooth lobe 5, and both sides of the sieve tooth locking ring 2 are correspondingly installed on the locking ring installation posts 8. The two sets of sieve tooth locking rings 2 are fixedly installed on the locking ring installation posts 8 through fasteners to fixedly install the sieve tooth lobe 5, and the sieve tooth lobe 5 is processed by a lathe. After the upper side of the sieve tooth lobe 5 is processed, a set of sieve tooth locking rings 2 between the two layers of tooth teeth 9 of the sieve tooth lobe 5 are removed, the sieve tooth lobe 5 is turned over up and down, and then the sieve tooth lobe 5 is fixedly installed and the other side of the sieve tooth lobe 5 is processed.

[0040] As Figure 6-8 shown, the completed sieve tooth lobe 5 is detected by the sieve tooth special card plate inspection tool 16, and the qualified sieve tooth lobe 5 can be installed on the sieve tooth installation shaft 14 to form the toothed roll 15 of the toothed roll crusher.

[0041] For an integrated tooling for sieve tooth processing and detection of a toothed roll crusher of the present utility model, by providing a tooling for professional detection and processing of the sieve tooth lobe 5, by matching the dovetail installation head 6 of the sieve tooth lobe 5 with the dovetail installation groove 4 on the cylinder adding platform 3, and then through the installation and fixation of the sieve tooth locking ring 2, the problem that the general processing method of the sieve tooth lobe is to weld several lobes into a whole circle for processing is solved.

[0042] Embodiment 2

[0043] As Figure 1-8 shown, for an integrated tooling for sieve tooth processing and detection of a toothed roll crusher of the present utility model, on the basis of the above embodiment, a limiting plate 12 is provided on the gap between two sieve tooth lobes 5 added to the cylinder adding platform 3.

[0044] The limiting plate 12 is of a triangular structure. The bottom edge of the limiting plate 12 is vertically connected to the cylinder mounting table 3, and the tip of the apex angle of the limiting plate 12 is aligned with the middle position of the lower layer of teeth 9 of the sieve tooth flap 5.

[0045] Through the provided limiting plate 12, there is a gap between adjacent sieve tooth flaps 5 during actual installation and use. The function of this limiting plate 12 can effectively prevent the situation where there is no gap between adjacent sieve tooth flaps 5 during assembly. That is, if the length of the sieve tooth flap 5 is too long, it will not fit into this tooling. The limiting plate 12 is designed as a triangular protrusion to provide a reference for scribing, leveling the lower row of teeth 9 of the sieve tooth flap 5 to be flush with the triangle, so that the teeth 9 are on the same plane.

[0046] For the integrated tooling for sieve tooth processing and detection of a toothed roll crusher of the present utility model, by providing a professional tooling for detecting and processing the sieve tooth flap 5, by fitting and installing the dovetail mounting head 6 of the sieve tooth flap 5 into the dovetail mounting groove 4 of the cylinder mounting table 3, and then fixing and installing it through the sieve tooth locking ring 2 provided, it solves the problem that the general processing method of the sieve tooth flap is to weld several flaps into a complete circle for processing.

[0047] Embodiment 3

[0048] As Figure 1-8 shown, for the integrated tooling for sieve tooth processing and detection of a toothed roll crusher of the present utility model, on the basis of the above embodiment, the sieve tooth locking ring 2 includes two half locking rings 13, and the head and tail of the two half locking rings 13 are connected by bolts to form a surrounding structure.

[0049] The head end of the half locking ring 13 is provided with a locking ear platform 7 connected to the locking ring mounting post 8, and the sieve tooth locking ring 2 is sleeved on the locking ring mounting post 8 through the locking ear platform 7 for fixed connection.

[0050] Another set of sieve tooth locking rings 2 is provided at the bottom of the sieve tooth flap 5. The set of sieve tooth locking rings 2 provided at the bottom of the sieve tooth flap 5 and the set of sieve tooth locking rings 2 provided in the middle of the sieve tooth flap 5 cooperate with each other to fixedly install the sieve tooth flap 5 on the tooling base 1.

[0051] For the integrated tooling for sieve tooth processing and detection of a toothed roll crusher of the present utility model, by providing a professional tooling for detecting and processing the sieve tooth flap 5, by fitting and installing the dovetail mounting head 6 of the sieve tooth flap 5 into the dovetail mounting groove 4 of the cylinder mounting table 3, and then fixing and installing it through the sieve tooth locking ring 2 provided, it solves the problem that the general processing method of the sieve tooth flap is to weld several flaps into a complete circle for processing.

[0052] As Figure 7The figure shows a schematic diagram of a special clamping plate fixture 16 for sieve teeth. After the sieve tooth lobe 5 is processed on an integrated tooling, the special clamping plate fixture for sieve teeth is used to detect the contour shape of the sieve tooth lobe 5. Only by passing the detection with the special clamping plate fixture for sieve teeth can the smooth installation during use be ensured.
